Abstract

The invention discloses an image signal processor and an image sensing processing system, in the processor, a reconfigurable interface module can perform interface configuration through compiling, read original image data from the outside of the image signal processor, and send the original image data to a reconfigurable digital signal processing module; a hardware architecture or a hardware connecting line in the reconfigurable digital signal processing module can be structurally recombined through software compiling, so that the hardware implementation requirement of an image processing algorithm is met, the original image data is processed, and the edge computing capacity is realized. Therefore, the image signal processor provided by the invention can be adapted to image sensors of different types or different specifications, has edge computing capability, and meets the requirements of algorithm processing based on an artificial intelligence theoretical model.

Description

technical field [0001] The present application relates to the technical field of image sensing, in particular to an image signal processor and an image sensing processing system. Background technique [0002] In the whole process of camera imaging, the image signal processor (Image Signal Process, ISP) is used to receive the original image signal data of the front-end image sensor, and perform post-processing on the signal output by the image sensor. The main processing includes linear correction, noise removal, Dead pixel removal, interpolation, white balance, automatic exposure control, etc. ISP is the computing processing unit in the process of taking photos. It occupies the core leading position in the camera system and is an important part of the camera. [0003] Generally, different image sensors have different interface standards, and output original image signal formats in different formats. Therefore, different ISPs need to be matched for image signal processing. ...
