There are a few common camera chips out there which are used by many
product manufacturers. Zoran's COACH series which was a MIPS core
system-on-a-chip that used to be popular. Many newer cameras with
video are using a chip called Ambarella which is an ARM core. I think
Panasonic has their own.
Keep in mind that in this day and age, having your own chip does not
mean designing it from scratch. Just as COACH and Ambarella use
existing CPU architectures, you can license the processor core,
license mpeg-whatever hardware acceleration blocks, license USB
interfaces, etc - and then pay a fab to make it for you. Still its a
big and risky project though, which is why there's a market for
digital camera chips that often come with a reference firmware/
development kit.
