Problems solved by technology

[0003] Most of the current ISP chips are function-customized chips, which can be directly used by customers after purchase, and the scalability is poor. Of course, customers can also provide requirements to manufacturers, and then manufacturers can customize functions for customers to use. The functions are different, and the peripheral devices are also different. It may be different, additional schematic design and layout are required, additional components need to be used, some special functions need to pay additional fees, and the design of ISP drivers also requires more time and energy. Some aspects increase the R&D cycle and increase the R&D cost

Abstract

The invention discloses a RAW-to-YUV conversion method for realizing MIPI CSI-2 based on an FPGA. The method comprises the following steps of A, converting the MIPI CSI data into the parallel port data; B, converting the parallel port raw10 data into the parallel port YUV422-8 data, carrying out gamma correction, AE and AWB on the parallel port data; and C, converting the parallel port YUV422-8 data into the MIPI CSI data. According to the method, the RAW-to-YUV conversion of the video data CSI-2 is realized based on the FPGA, the FPGA has flexible programmability, and the own requirements ofthe FPGA can be met by modifying the source codes on the basis that a peripheral circuit does not need to be modified, so that the development period is greatly shortened, and meanwhile, the development cost is also reduced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for converting RAW to YUV of MIPI CSI-2 based on FPGA. Background technique [0002] At present, the most widely used scheme is to use ISP (Image Signal Processor, Image Signal Processor) to process the image signal output by the image signal sensor. Gamma correction, strong light suppression, color enhancement, AE (Auto Exposure, automatic exposure), AWB (Auto White Balance, automatic white balance processing) and other processing, rely on ISP to better restore the scene under different optical conditions detail. [0003] Most of the current ISP chips are function-customized chips, which can be directly used by customers after purchase, and the scalability is poor. Of course, customers can also provide requirements to manufacturers, and then manufacturers can customize functions for customers to use. The functions are different, and the peripheral devices are ...
