Does anyone have any information on the chip inside the Fisher Price video camera that acts as the lens? Is that the same chip found in digitizers? I can think of several interesting uses for such a thing. It must be inexpensive, as the camera sells for around only $100. Any information is appreciated.

The chip is made by Sanyo, with a resolution of 100 by 160 pixels, black and white. It uses a "bucket brigade" technology, which scans the image out by shifting the rows down to an output shifter. I don't remember the number, but you should be able to find it out from Sanyo. Incidently, Seiko Epson/SMOS make a _much_ better device, called the HD7010. It is 244 x 244 pixels, and uses an interesting output scan mechanism that avoids shifting the data across the screen (essentially, it addresses each pixel directly). I don't have my data here at work (I do toy design indepently from my _real_ job), but I will post what I have on _*cheap*_ video circuits in a day or two. (I've looked into it several times in the past) Be patient TRH
