Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image data processing method, system and electronic equipment based on a system on chip. Background technique [0002] At present, the existing image processing system or image sensor is composed of light sensing device (bayer array) + analog signal operation module (ASP: Analog Signals Processor) + digital control module (DCP: Digial Control Processor) + digital image processing module (ISP: Image Signal Processing) + data interface (IF: InterFace); wherein, the digital image processing module (ISP: Image Signal Processing) uses an application specific integrated circuit (ASIC: Application Specific Integrated Circuit) to execute image processing algorithms, resulting in the use of existing A product developed by an advanced image processing system or an image sensor has a fixed algorithm, poor variability, and a long design cycle. [0003] At the same time, ...

AI Technical Summary

Problems solved by technology

Existing image processing systems or image sensors cannot meet the requirements of product development, nor can they meet the needs of customers

[0005]Secondly, when traditional image sensors or image processing systems process image data, they completely rely on hardware solidified algorithms, which can support fewer scenarios and the scale of algorithms is limited. The hardware resources are limited, unable to meet the ever-changing needs, and poorly support complex scenarios

[0006] In the third aspect, with the current image processing circuit, when new requirements are added or new algorithms are updated, only hardware redesign can be carried out, and the market launch cycle is long , often after being put on the market, a long period of time has passed, and the demand may have been updated a lot, and it is completely impossible to keep up with the market rhythm
