Abstract: A light sensing apparatus includes a light sensing module, a signal conversion module and a processing module. The light sensing module is configured to output a first and second sense signals according to a light intensity emitting thereon. The signal conversion module is electrically coupled to the light sensing module and configured to receive the first and second sense signals and output a sense value according to a relative difference between the first and second sense signals, The comparison module is electrically coupled to the signal conversion module and configured to adjust a light sensing characteristic of the light sensing module according to the sense value so as to adjust a light sensing characteristic of the light sensing module. An adjustment method for a light sensing apparatus is also provided.
