Device and method for adaptively adjusting supporting parameters of image signal processor

Abstract

The invention provides a device for adaptively adjusting supporting parameters of an image signal processor, which is used for adjusting correction parameters of a lens correction module, an automatic white balance module and a color matrix correction module. The device comprises a storage system and a configuration module, wherein, the storage system is used for storing the correction parameters under different light sources which are obtained through off-line correction of the lens correction module, the automatic white balance module and the color matrix correction module; and the configuration module is used for selecting the corresponding correction parameters from the storage system and providing the correction parameters to the lens correction module, the automatic white balance module and the color matrix correction module for use according to types of the light sources determined by the automatic white balance module. Therefore, the device provided by the invention has the beneficial effects of preventing situations that one faulted of the three modules can cause color errors and is difficult to locate, lowering parameter debugging difficulty of the image signal processor adaptive to multiple light sources, and meanwhile effectively improving image quality while being applied to parameter debugging of the common image signal processor.

Description

technical field [0001] The invention relates to a device and method for adjusting the matching parameters of an image signal processor, in particular to an adaptive adjustment device and method for matching parameters of an image signal processor applied to a mobile phone. Background technique [0002] Due to the limitation of cost and volume, the lens and image sensor used in mobile phones can provide poor imaging quality, which requires the image signal processor used in mobile phones to have more complex image processing algorithms to correct and compensate for this aspect. of innate deficiencies. For example, a more complex lens correction algorithm is required to compensate for the large brightness drop at the edge of the field of view and the color unevenness of the full field of view in the camera lens of the mobile phone, as well as the color accuracy and saturation obtained by the direct interpolation of the image sensor used by the mobile phone. There is a big gap...
