Claim:
1. A method of implementing an uneven timing gap between each image capture in an image sensor comprising: capturing by a pixel array image data of a first frame with a first exposure time, a second frame with a second exposure time, a third frame with a third exposure time, and a fourth frame with an fourth exposure time, wherein the first, second, third and fourth exposure times are different, wherein timing gaps between capturing the first and second frames, the second and third frames, and third and fourth frames are uneven, acquiring by an analog-to-digital conversion (ADC) circuitry the pixel data signals, wherein the ADC circuitry that includes a plurality of ADC circuits, wherein the ADC circuitry is disposed in a second semiconductor die, wherein at least one of the pixel groups in each of the pixel sub-arrays is coupled to a different ADC circuit from the pixels groups remaining in each of the pixel sub-arrays; and for each of the first, second, third, and fourth frames, converting by each of the ADC circuits the pixel data signal received from the pixel groups respectively coupled thereto from analog to digital to generate a plurality of ADC outputs.
