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.

Claim (Index 13):
An image sensing apparatus, comprising:\n a pixel array, comprising an optical black area and an active area; a reading circuit, coupled to the pixel array, and configured to generate a plurality of original pixel data of a plurality of pixels in the active area and a plurality of black level values of a plurality of pixels in the optical black area; and a black level correction circuit, coupled to the reading circuit to receive original pixel data of one of the pixels in the active area, and configured to generate a black offset with respect to the pixel according to a plurality of reference black offsets with respect to a plurality of reference pixels neighboring the pixel and a ratio, and generates corrected pixel data of the pixel according to the original pixel data of the pixel and the black offset, wherein the ratio is determined according to current thermal noise information and reference thermal noise information.
