Abstract
An image sensing device and image sensing method are described herein. By way of example, the imaging sensing device includes a two-dimensional array of light sensing elements, each light sensing element being configured to generate an output signal indicative of an intensity level of light impinging on the light sensing element, one or more analog-to-digital converters configured to digitize output signals read out from the array of light sensing elements to generate digital output pixel values, a control circuit configured to generate digital pixel reset values, and a compression module configured to receive the digital pixel reset values and to generate a compressed digital pixel reset value corresponding to each digital pixel reset value.
