Abstract: An image signal processor includes a shared circuit, a first circuit, and a second circuit. The shared circuit processes input image data. The first circuit provides a first algorithm for processing the input image data and is used by the shared circuit to process the input image data at a first operation mode in a first shooting environment. The second circuit provides a second algorithm for processing the input image data and is used by the shared circuit to process the input image data at a second operation mode different from the first operation mode in a second shooting environment different from the first shooting environment.

Abstract: An image signal processor includes a statistic data generating unit for receiving an image signal from an external device, an image processing unit for receiving the image signal, and a direct memory access (DMA) module connected to the statistic data generating unit and the image processing unit. The statistic data generating unit performs first image pre-processing on the image signal and generates first statistic data based on the image signal subjected to the first image pre-processing. The DMA module stores the first statistic data therein and provides the stored first statistic data to the image processing unit. The image processing unit performs second image pre-processing on the image signal and performs image processing on the image signal based on the first statistic data.
