SmartParts SPDPF70EW (Centrios) 7" digital picture frame review

SmartParts SPDPF70EW / Centrios 7" digital picture frame is about as simple and bargain-basement a frame as you can get.  (Sold as SmartParts in the USA, Centrios in Canada.)  There is no included software (although you can download the OptiPix application from the net, using your frame's serial number).  There's no separate power switch, instead hold down Play/Pause to power it on and off.  There's no way to change the slideshow interval and there's no choice of slide transitions.  It doesn't support Compact Flash, it can take SD/MMC, Memory Stick, and xD.  No remote, no speakers, no MP3s, no video, no format other than JPEG.  The resolution is only 480x234, made even worse by the aspect ratio issue, which means if you want to preserve your digital photo's 4:3 aspect, you really should size your pictures to 312x234, and you will have black bars on either side of the screen (a problem common to all widescreen digital picture frames).

So, it depends who will be using the frame.  If it's for a non-technical user, it might be good.  Other frames have elaborate remote controls and many menus with preferences settings, which could be overwhelming.  This frame is basically fool-proof in that way.  Play/Pause, Prev, Next, Rotate and Switch Display Mode are the only options.  As soon as you put in a memory card it immediately starts running a slideshow.

Side-by-Side

Here is the SmartParts frame (wood frame, left) next to the higher-end Kodak SV811 (black plastic frame).  The difference in the resolution (sharpness of the image) is noticeable (the SV811 has a 800x480 display).

OptiPix

Basically the sole function of OptiPix Pro is to help you load the memory card, it again is about as simple an application as you could get:

1. Select Photos

2. Process and Save Locally

It will "optimize" the photos, oddly what it appears to do is resize large images down to 1024x768.  I don't quite understand how this is an optimization, considering it is still more than double the resolution that the frame can display.

3. Copy to picture frame (removable storage)

It is nice that it walks one through the basic steps, but after it copies to the removable storage, it doesn't provide any instructions on safely stopping/unmounting the drive, so one may end up with improperly disconnected or unclosed file systems.

Also the image quality is not great.  In addition to the low resolution, the display is unusual for an LCD in that it has the appears (under careful examination) of either being underdriven in terms of refresh rate, or being run in an interlaced (alternating lines displayed) mode.  If you look quickly up and down the screen as the display is running, you can actually discern the lines on the screen.  This is quite different from other frames I have seen (e.g. the Kodak SV811 and KSPF-2000 which have smooth, rock-solid LCD displays).

If the price difference were huge between this and higher-end frames it would perhaps be justified, but it's in roughly the same price space as e.g. the Kodak SV710 7" frame (Kodak Easyshare SV-710 7-Inch Digital Picture Frame at Amazon.com), which has a lot more features, albeit the same 480x234 resolution.

I do like the wood frame on the SmartParts.  But to me I would select the SmartParts frame only if it's on sale at a great price, or if you want an absolutely dead-simple frame that's basically impossible to screw up, and if you're sure whoever will be looking at it isn't going to be bothered by (or notice) the flicker in the display.  The frame is bright and the image is certainly acceptable from a distance.  If you want to show off your photos in a more serious or professional way, you're definitely going to want a higher-resolution frame.

Windows and .NET installer cleanup

Sometimes your Windows machine just gets stuck.  It won't let you install new software, or uninstall old software.  You may get errors about missing patches or install files.  This problem can also happen with Office apps and MS Money if you have cloned (made a bootable backup of) your hard drive, using e.g. Western Digital Data Lifeguard Tools™.

For cases like that, when all other options have failed, you can use the Windows Installer CleanUp Utility.  It will go through and clean up (delete) the installer information itself, while leaving the applications and their data untouched.  This has enabled me to install Acrobat 8 when there were uninstall problems with Acrobat 7, and to install the latest version of QuickTime after there were uninstall problems with that as well.  (Note: if you are having persistent problems of this type, you may want to consider doing a complete backup and clean reinstall of Windows, as your registry may be destablising.)

Because it leaves your apps and data intact, it is a fairly safe tool.

A more dangerous but still useful one is .NET Installation Cleanup Utility.  It can help you when you need .NET but are running into install issues.  However be aware

This cleanup tool will delete shared files and registry keys used by other versions of the .NET Framework.  If you run the cleanup tool, you will need to perform a repair or reinstall for all other versions of the .NET Framework that are on your computer to get them to work correctly afterwards.

In other words, after the cleanup you will have to reinstall or repair any versions of .NET you need.  (e.g. to fix .NET 2.0 after running cleanup on .NET 1.1, go into Control Panel->Add or Remove Programs, locate the entry for "Microsoft .NET Framework 2.0", select "Change/Remove" and then select "Repair").

K790 audio jack constructed

There's no FastPort adapter in my K790 phone to let you plug in a set of regular headphones.  So...

One Sony Ericsson MMC-70 FastPort to male 3.5mm audio

One RadioShack (err, TheSource or whatever it's supposed to be called) 3.5mm female-to-female

and hey presto: FastPort headphone adapter

Sony MMC-70 from PureMobile.ca, since SonyStyle.ca doesn't seem to sell it.

In the US, you can buy an MMC-70 from Amazon.com.

So step one in using my K790 phone to replace an iPod is complete. The next test is to see whether it has anywhere near the battery life that is needed.  Ideally I'd like to get 6 hours of audio out of it.  Then I could replace ipod-on-a-plane. Of course, the iPod nano is pretty freaking small anyway, but it's the principle of the thing.  Device consolidation.

Sony GPS Logger On The Go - bridge to your Mac

For the Sony GPS-CS1 (and GPS-CS1KA) only, you can get around the lack of Mac compatibility by using what's called a USB On The Go (OTG) bridge (sometimes called a link bridge or a storage bridge).  This is a stand-alone device that allows two USB storage devices to transfer files directly, without needing a computer in between.  For GPS logger, this will work only with the Sony because it is the only one of the devices that I know of that acts as a regular USB storage device.  (Other GPS loggers provide only a serial-over-USB interface to access their data.)  So the scenario is you attach the Sony to one side of the bridge, and a USB memory key or other Mac-compatible storage device to the other.  Move the files from the Sony to the other storage, and then e.g. remove the USB memory key and use the USB memory with your Mac as you would normally.

The info about the bridge is from Ben Ng, he reports the Acrox OTG Storage Bridge (model OG4) worked, it appears to be the same as the Sharkoon USB Link Bridge (which was circa 2004, model LXZS01 I think).

In general OTG seems to be a 2004-2005 technology without many new devices since then.  The Sima Hitch is one more recent entry into the field, see Communications from Elsewhere for more info.

These devices are often positioned as ways to download or backup images from a digital camera.  If possible you should test the bridge for Sony compatibility beforehand.  In general most of the compatibility issues I have seen reported are for bridging much larger storage devices (which brings all the usual partition size and NTFS issues).  Also the devices usually transfer at slow USB speeds (12Mbps).  The Sony only has a small amount of storage (32MB), with small files, so as long as you're copying it to a normal USB key (e.g. a thumb drive with a few gigs of storage) any compatibility and speed problems should be minimized.

Note: I have not tested this solution myself yet.

If you find other bridges that are compatible, please let me know.

Here are some starting points from Amazon.com, keeping in mind the above issues:

Kodak SV811 digital picture frame vs. KSPF-2000: how much has changed in 7 years?

Summary

It's not really a fair comparison, as the older frame (KSPF-2000) was more expensive than the new, wider one (SV811).  It is interesting to be able to compare similar devices from the same brand, seven years apart.  I actually prefer the industrial design of the older frame.  Plus if I display the entire digital photo in its proper aspect ratio, I don't actually get any more usable display on the widescreen frame than I already had on the old frame.  However, the newer frame has a brighter display, with a wider face-on set of good viewing angles.

I will have a followup review comparing four current digital picture frame models.

Details

Kodak was early to market in the digital photo frame space, with the KSPF-2000.  Courtesy of Internet Archive, you can see what their site looked like on October 19, 2000: KODAK Smart Picture Frame.  There was even a telephone modem based network called StoryBox (that required a subscription), for sending images to frames.  You could also order prints from the frame itself.  The frame is 6.4" diagonal, 640x480: a good match for the aspect ratio of digital photos.  It supports Compact Flash cards only.

The frame was not successful, probably a combination of the market not being ready for it, and the price (U$350 - roughly U$410 in today's dollars, plus a subscription fee).  The situation was however good for those few savvy buyers who understood the product, as they were able to snap the frame up at fire-sale prices after it was discontinued.  (You may still be able to do the same these days, as old frames occasionally show up on eBay.)

It's unfortunate for Kodak that they weren't able to stay in the market, as they could have been a lead player.  Now that they are back in digital picture frame business, they are just one player amongst many brands large and small.

They have a 7" widescreen model, the SV710, but I will look at the larger one, the widescreen 8" SV811 (Kodak SV-811 8-inch Digital Picture Frame at Amazon.com)  The frame resolution is 800x480.

An Aspect of Digital Photos

Aspect ratios: digital camera images are typically 4:3 (1.33...), so e.g. 640x480, 800x600, 1024x768, 1600x1200, 3072x2304.

So it is puzzling why the digital picture frames are all adopting 16:9 (1.77...) aspect ratios, which would be 640x360, 800x450, 1024x576, 1600x900, and so on.  It means that the display is simply not a good scalable match to the image.  I suppose it is probably because most of the small LCD screens being manufactured these days are for DVD players, which do need a 16:9 widescreen ratio, so screens in that form factor are probably cheaper.

So if you set your widescreen frame to "fit entire picture" rather than "fill entire screen", you end up with the rather ridiculous situation of only using the centre of the screen, with black bars on both sides.

Side-by-Side

Here's what they look like side-by-side, the older KSPF-2000 is the one with the wooden frame on the left.

I have to say, I think the styling has gone downhill.  The new model has a wide black frame (which is 1.25" larger than the actual body of the display, I guess to make you feel like you're getting a big step up from a 7" frame). 

Photo: SV811 wide plastic frame

However, the newer model has a noticeably brighter screen, the older KSPF has an almost matte effect on its screen, with a narrow range of good viewing angles.

I had a tough time to capture any images that give a good representation of the frames side-by-side in terms of image quality, sharpness, brightness etc.  There's a lot of complexity with the screens glowing and dependencies on light angles and lighting conditions.  I can certainly say that in terms of sharpness the screens are basically indistinguishable.  In terms of colours, the KSPF shows quite a bit darker than the SV811, and the newer frame is probably the more colour accurate of the two.  Take the next set of images with a grain of salt - slightly different lighting conditions or angles would give different results.

Here are two macro shots of the screens, first the KSPF-2000

and then the SV811

There are other features of the KSPF that I prefer: the controls are simple, with shapes recognizable by touch, and easily accessible, and it has rubberized feet at the back, so it doesn't slide around.  The SV811 has quite complex controls that are at the back of its deep frame, so (unless you are using the remote control), you have to lean quite far over to look at the labels in order to select which of the identical black circular buttons to press.  As well, both the front and back edges are just hard plastic, so it tends to slide easily on a hard surface like a wooden table.

The SV811 built-in controls lack left and right buttons, it only has up and down buttons, so some functions, such as setting the time, appear to only be possible using the remote control.

The firmware that came with the SV811 was 2007.3.27 Worldwide, I upgraded to 2007.7.03 Worldwide

Kodak provides software support for both Windows and Mac, including for frame firmware updates, which is very nice to see.  The firmware update is possible because the frame can mount as a USB drive, so you just attach it to the platform of your choice and copy the firmware update over, and then just run Settings->Upgrade Firmware.

SV811 Mac Firmware upgrade - issues

1. The instructions are written mostly for a Windows PC.

2. The Mac will show drive icons for both the 128MB internal frame memory and the memory card.  The internal memory doesn't have a name assigned.  When you try to unmount these drives, before disconnecting the USB cable, they just automatically remount.  If you just disconnect the cable as the instructions direct, you will get an "unexpected disconnection" message on the Mac.

More on software and features

Almost all the information about the KSPF is gone from the Kodak site.  There are two old FAQS: "Registered, Network-Connected KODAK Smart Picture Frame" and "Non-Network KODAK Smart Picture Frame".

The SV811 frame came with EasyShare 6.2, but version 6.4 is available for download for Windows (version 6.1 for Mac).

The SV811 adds a number of new capabilities beyond what the older KSPF frame can do: the new frame has a built-in speaker (and can play MP3s), it can play movies and it can be mounted on a computer as a USB drive.  It can read directly from digital cameras or USB memory keys and storage devices.

As well it reads multiple card formats, including the ability to support the insertion of both a small-format card (e.g. Memory Stick) and a CF card - it will display both in the interface.

You can also copy between all storage options - between cards and from cards to internal memory.  Copying card to card in this way is pretty darn slow though (of course it will depend on the card read/write performance as well) - I wouldn't doing this unless it is your only option, it doesn't provide any information other than a progress bar, and in my case it failed after a partial copy with an "unable to create file" message.

It can print directly from the frame (over USB) to a PictBridge-enabled printer.

It comes with a remote control that can be used to navigate the interface as well as stop and start slideshows.
