Embodiment 1

[0071] The first embodiment of the information processing method provided by the present invention is applied to an electronic device, and the electronic device has an ISP function or includes an ISP. In the ISP, Color Enhancement is an important component, through which at least one aspect such as brightness, saturation, and hue of an image can be enhanced. Among them, adjusting the saturation is to deepen or lighten the current color; adjusting the hue is to adjust the current color to another color.

Abstract

The embodiment of the invention discloses an information processing method and an electronic device. The method comprises the steps of extracting a pixel point satisfying a first preset rule in a first image when the first image is obtained, thereby obtaining the first pixel point; determining first data corresponding to the first pixel point, wherein the first data represents a first attribute of the pixel point; determining a first characteristic value of the first data; and carrying out first adjustment on the first data according to the first characteristic value. According to the method and the electronic device, aspects of brightness, saturation and hue of the image can be adjusted simply and effectively by an image signal processor (ISP).

Description

technical field [0001] The invention relates to information processing technology, in particular to an information processing method and electronic equipment. Background technique [0002] In order to achieve a better display effect of the image, in the field of image processing, the brightness, saturation, hue and other aspects of the specified part of the image are usually adjusted. For example, enhancing the tone of the face in a figure painting will make the face more rosy; enhancing the saturation of the grass in a landscape painting will make the color of the grass greener. At present, the commonly used adjustment method is mainly based on the Mahalanobis distance method, that is, the color difference signal of the part of the image pixel is adjusted according to the distance between the color difference signal of the part of the image pixel and the reference sample, so as to achieve the adjustment purpose. Among them, the Mahalanobis distance formula is more complica...
