Problems solved by technology

Due to the structural design of the mobile phone lens or sensor sensor, often only part of the information of the current environment can be seen, so part of the environment color information received by the AWB algorithm cannot fully reflect the current environment, so it can only be based on the received part of the environment color information, To restore the real light source color information at the algorithm level, resulting in low accuracy of color restoration

Abstract

Embodiments of the present application provide a scene color restoration method, a terminal, and a storage medium, including: respectively acquiring multiple first DC components corresponding to the first frequency channel and multiple first DC components corresponding to the second frequency channel through multiple color temperature sensors. Two direct current components and multiple visible light band components; use multiple first direct current components, multiple second direct current components, multiple visible light band components and a preset classification model to obtain scene classification results, and determine the light source corresponding to the scene classification results Statistical area; perform white balance processing based on the light source statistical area, output current color temperature related parameters, and output multiple sets of color temperature related parameters through multiple color temperature sensors, each color temperature sensor corresponds to a set of color temperature related parameters; according to the current color temperature related parameters and multiple color temperature related parameters Set color temperature related parameters, and perform automatic white balance AWB correction on the image.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a scene color restoration method, a terminal, and a storage medium. Background technique [0002] Most of the industrial automatic white balance (AWB) algorithms are calculated based on the statistics of the Internet Service Provider (ISP, Internet Service Provider) provided by the chip manufacturer. The field of view of the sensor determines the AWB algorithm can obtain "Environment" information received. Due to the structural design of the mobile phone lens or sensor sensor, often only part of the information of the current environment can be seen, so part of the environment color information received by the AWB algorithm cannot fully reflect the current environment, so it can only be based on the received part of the environment color information, To restore the real light source color information at the algorithm level, resulting in lower accuracy of color restorati...
