Well, may be I am all wrong but here is what I see as some fundamental problems!

The Kodak chip is outputting video signal at a typical frequency of 4MHZ and this is before any anti-aliasing filter which means high edge transitions from the CCD.

Even at 20MHz, A/D acquisition time is about 2.4usec - refer to data on page 230-231. This is defined by the internal S/H cap =20pF and the sampling switch impedance. You haven't given the settings for ADCON2?

You are trying to use LF411 or LM741 - these op amps CANNOT handle the signal bandwidth as they will slew rate limit the signal with heavy distortion. But this is academic as you cannot sample the input signal adequately (remember Nyquist) with a Tacq=2usec and even with a minimum Tad =2.

So unless your read out clock is slowed down so that CCD analog output is limited to around 400kHz, I think you are out of luck with the PIC. They don't have video bandwidth ADC.

As Ralph and Steve are trying to figure out from your posting, there is really no info on signal amplitude and shape! Oscilloscope can obviously show these waveforms as it has adequate input bandwidth. Hence my discouraging input..... Anyway, please read datasheet Section 19 and you will get a better idea of how the ADC is configured.
