Abstract
An image sensor includes an analog-to-digital converter (ADC) and a decimation filter. The decimation filter includes a first digital data generator and a second digital data generator. The first digital data generator is configured to integrate sigma-delta modulated M-bit pixel data and output N-bit pixel data based on an integration result. The second digital data generator is configured to integrate the N-bit pixel data, generate P-bit pixel data based on an integration result, and output the P-bit pixel data as decimated data.
