A CMOS light sensor and the operation method thereof are disclosed. The CMOS light sensor has a plurality of light sensing lines and a plurality of capacitor lines. Each light sensing line has a plurality of light sensors such that the number of capacitors in each capacitor line is smaller than the number of light sensing cells in each light sensing line. The capacitors are used for holding a portion of the potentials produced by the light sensing cells due to illumination. The method of operating the CMOS light sensor includes transferring the data captured by the light sensing line to the capacitor line and reading out the data according to a pre-defined order so that the leakage of charges from the capacitor is reduced.

CMOS light sensor with the quantity of light sensing cells along a line is more than the quantity of corresponding capacitors and operation method thereof
