Can someone suggest a reasonably-priced monochrome camera module (I
can live with color but don't need it), VGA-resolution camera module
with some kind of buffer and low-speed interface; SPI, I2C, RS232,
etc. SPI would be my preference.
I need two of them, and perhaps two spares, to build a demo platform
for a student to work with very simple stereoscopic machine vision.
Currently he is working with a PC and two USB webcams but he wants a
smaller system to go in a vehicle without requiring huge batteries,
plus he doesn't want the overhead of a USB stack. We've put together a
general block diagram for his circuit and have good candidates for
most of the components, but the cameras are a sticky point.
I really want uncompressed or lossless data (preferably de-Bayerized
if color) - we don't really want to deal with JPEG artifacts. 0.5-1fps
is fine.
All the cellphone camera modules I've looked at appear to be bare
image sensors requiring a real-time DMA ****t to acquire the data. The
Ovis-based hobbyist solutions like the C328R from <http://
www.electronics123.com/s.nl/it.A/id.2027/.f?sc=8&category=241> are
pretty much what I want, except for the unavoidable JPEG compression.
A $50 price point @[EMAIL PROTECTED]
qty 5 is fairly sweet - obviously cheaper would be
better.
Thoughts?
Gracias.
