Default image processor chip inside Canon, Sony, olympus, Fuj?

Dear All,

I just wonder whether all brands of the digital cameras such as Sony, Canon, Olympus, Fuj, Kodak using their own digital imaging processor chip or some of the brand use other vendor chip? If possible, which vendor provides the chip and in what model?

Please help! Thanks!

Best Regards,

There's only examples, but no generalisation, unless the camera manufacturers publish their design specs.

A good example is the different flavor of the Sony's 5Mp CCDs which is used in the 5000/5700, D7/D7i/D7Hi, F707/F717, and E20.

Kodak usually use their own except for the 14n where they source it from Fill factory: http://www.kodak.com/global/en/digit...=0.1.4.6&lc=en

Fuji features their diagonal array CCD where they can also interpolate to higher resolution pictures with their consumer cameras, as well as in the S2 dSLR with a Nikon body...

... and then there's numerous other CCD manufacturers with names you never heard of (especially now with cell phone cameras picking up!)

Dear NHL,

Thanks for the information. But what you mentioned is about CCD/CMOS sensor chip, are there any information about the backend digital IC that handled AE, AF, AWB and jpeg compression?

Best Regards,

You can do a search @ dpReview for any particular camera you're looking for, but I'm more familiar with the D7's. Like most manufacturers, Minolta designed their own Application Specific IC (ASIC) to perfom the A/D as well as control/timings for their camera's CCD followed by a RISC processor from MIPS. The later provides custom image processing as well as to interact between the user and the camera:

You can also follow the previous links that I've posted to acquaint yourself with commercially-of-the-shelf control IC that other manufacturers can used instead of developing their own ASIC.

As to the processors, the most common ones are surprisingly not Intel nor AMD's... They tend to be mostly a RISC type like the low-cost Hitachi Super H or their licensees, if you dig a little deeper even the camera's OS is sourced !!! :lol: :lol: :lol:
