1. An image sensing device comprising:
an array of light sensing elements configured to output reset signals and light-dependent (LD) signals;
an analog-to-digital converter circuit configured to digitize the reset signals into digital reset values and to digitize the LD signals into digital LD values;
compression circuitry configured to generate compressed digital reset values based on the digital reset values and to generate compressed digital LD values based on the digital LD values.
