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.

Abstract: An image processing apparatus for sharpening edge boundaries of an image is provided. The image processing apparatus includes a transient improvement (TI) circuit and a color protection circuit. The TI circuit receives multiple original pixel data and performs a TI process on an original target pixel data from the original pixel data to output first and second TI chroma signals corresponding to the original pixel data. The color protection circuit respectively compares the first and second TI chroma signals with first and second original chroma signals of the original pixel data to correspondingly generate a weighting value, and outputs first and second adjusted chroma signals according to the weighting value, the first and second original chroma signals, and the first and second TI chroma signals.
