Abstract: An image sensing apparatus, a black level correction method thereof, and a computer readable medium are provided. The image sensing apparatus comprises a pixel array and a black level correction circuit, and the pixel array comprises an optical black area and an active area. The black level correction circuit generates a black offset with respect to a pixel in the active area according to a plurality of reference black offsets with respect to a plurality of reference pixels which are neighboring the pixel and a ratio determined according to a current thermal noise information and a reference thermal noise information. The black level correction circuit generates a corrected pixel data of the pixel according to original pixel data of the pixel and the black offset.
