Abstract

The invention relates to a RAW format file conversion method and system, an electronic device and a storage medium, and the method comprises the steps of obtaining camera parameter configuration and a Bayer array from a RAW format file, processing the RAW format file through an ISP algorithm, and generating a standard ISP original data set; performing color correction on a standard image in the standard ISP original data set through a color correction model, obtaining a color correction image, and wherein the color correction model is an image enhancement neural network embedded in a control command module; respectively extracting a color correction feature matrix of the color correction image and a RAW feature matrix of the Bayer array through a neural network, and fusing the color correction feature matrix and the RAW feature matrix through a fusion operator to obtain a high dynamic color range feature matrix; and converting the high-dynamic color range feature matrix through a high-definition neural network to generate a file conversion picture. According to the invention, an automatic file conversion method is provided for the RAW format file, and the quality of the converted picture can be effectively improved.

Description

technical field [0001] The present application relates to the field of computers, in particular to a method, system, electronic device and storage medium for converting files in RAW format. Background technique [0002] RAW format pictures are unprocessed raw camera data, which retains the details, colors, and continuous information of light and shade to the greatest extent, and provides the largest image processing space. It is the first choice for professional image processing. In the near future, the network speed and bandwidth will increase. In the 5G era, highly flexible raw formats or image formats with higher color depth obtained by processing raw formats will become more popular. [0003] At present, the latest mainstream mobile phones all support the Raw format. For example, the recently released Iphone 12 supports the ProRaw format. Photographers can fully retain the control of color, details and dynamic range when shooting, but they can also obtain the powerful de...
