description An image sensing device with improved image quality is provided. The image sensing device includes: a pixel array that outputs a pixel signal; a comparator that compares a reference signal and the pixel signal and outputs a comparison result signal; a counter that counts the comparison result signal and outputs a count result signal corresponding to m bits; and an image signal processor that performs correction on the count result signal and outputs an image signal corresponding to n bits, wherein m and n are integers, and m is greater than n. 이미지 품질이 향상된 이미지 센싱 장치가 제공된다. 이미지 센싱 장치는 픽셀 신호를 출력하는 픽셀 어레이, 기준 신호와 픽셀 신호를 비교하여 비교 결과 신호를 출력하는 비교기, 비교 결과 신호를 카운팅하여 m 비트에 해당하는 카운트 결과 신호를 출력하는 카운터, 및 카운트 결과 신호에 대한 보정을 수행하여 n 비트에 해당하는 이미지 신호를 출력하는 이미지 신호 프로세서를 포함하고, m과 n은 정수이고, m은 상기 n보다 크다.
