Abstract:
A scheme is provided that enhances the dynamic range performance of images via multiple readouts during one exposure. The readout process circuit structure includes at least an analog-to-digital converter (ADC). The analog-to-digital converter converts analog data generated from an image sensor into digital data, allowing sub-frame readouts for improving a dynamic range of the image sensor. Additionally, methods of partial digitization (not a full number of bits) and image array are provided.
