Hi,

Recently I purchased a small alarm clock with a hidden camera and motion
detector embedded just to see how it works. It stores the video on a small
MMC card and 1GB holds about 20 mins of footage. Upon evaluation I found a
small 640 x 480 camera module connected to an STK1262 controller from
Syntek. This controller compresses the image to be stored on the MMC. I
have been unable to find a similar IC that will convert raw video and
compress it to JPEG/MPEG and Syntek are one of those Chinese companies that
seem very hard to deal with.

I was wondering if anyone out there has had any experience with this sort of
concept and could recommend some IC's for me to look at. The simpler the
better, I'm not interested in high resolution right now

Any feedback would be greatly appreciated.

Best regards


Adrian Hamilton

It has been done in FPGA.

For a consumer product it's probably an ASIC, with purchased IP to do
the compression. You could probably do it in an FPGA, possibly even an
inexpensive one (depending on how you define inexpensive). Dunno if you
could cram it into a DSP, though.

Do you need to implement control loops in software?

Thanks JB and others for your reply,

I have stumbled across the Conexant CX93510 in my searches. Have you have
any experience with this IC. Can I ask what you project involved?


Regards,


Adrian
