QV-10A

The QV-10A does not do well in low light levels, such as normal indoor lighting (it does even worse in lower light levels such as a bar) and produces underexposed, noisy (grainy) images which are often blurry because of the long exposure time used at these light levels; otherwise, I would have taken more pictures during the talks. The QV-10A can store 96 separate 320x240 resolution (after aspect ratio correction) still images. The newer QV-100 and QV-300 models can do 640x480. A dye sublimation printer is available which talks directly to the camera for printing the images. Note that the new QV-700 model has a flash.

These images have been processed with cjpeg/djpeg and NetPBM under linux to correct aspect ratio, brightness, and rotation and to produce the thumbnails.

There is a command line program called QVplay available on the net which runs under various un*x variants as well as ms-dos and windows and which allows upload and download of images and taking a picture. There seem to be some utilities for other brands on the same ftp site. Note that while QVplay's documentation is all in Japanese, it is pretty easy to install. Untar, run configure, run make, copy binary. And this command will list available options:

   qvplay -h 

Casio, the company, is pretty worthless. They have been unresponsive to inquiries regarding the camera. The camera is only useful because of a driver program developed by a private individual, who works for sony. Incidently, sony now sells the Sony Mavica which has a power zoom and instead of having a computer interface writes images in standard jpeg format to 3-1/2" floppies, making

Here is someone else's review of the QV-10. Since Casio's web page is down, you won't find a link here. Downloading images
