Clocking a CMOS imager - Is this feasible?

i'm in planning stage of project, trying figure out whether it's feasible clock cmos imager of arduinos.  when cmos imager, i'm not talking 1 of system-on-a-chip cameras in mobile phone.  i'm talking detector 8 column address lines, 8 row address lines, reset, clamp, adc start convert, etc., need set in order thing output analog pixel level, digitized off-chip.  of course there boards can (non-programmable, whole frame reads), , asics can better (read out multiple sub-frames), i'm interested in doing on low-cost, programmable, open platform arduino.  end goal give the microcontroller list of sub-frames , have address them @ ~50+ khz pixel rates.

while digital outs can controlled digitalwrite(), slow , i'm not sure how digital outs sync because of latency.  there better ways control digital outs?  timer outputs attractive, can used other simple clock line or pwm?

yes possible.

if sure can use direct port output:-
