Abstract

The invention relates to a digital camera, in particular to digital camera photosensitive control and aims at solving the problem that photosensitive control parameters of the digital camera at present are fixed and cannot be intelligently adjusted. A digital camera photosensitive self-adaptation control method comprises the steps of dividing an image into a plurality of small blocks, calculating brightness values of the small blocks, setting a series of calculation comparison rules and performing extreme brightness and extreme dark light reflection control, image brightness color control, image darkness control and image gradation control on the image. The method has the advantages that the exposure time, image brightness, contrast ratio, exposure compensation and Gamma of a Sensor are controlled by calculating sensitivity of the image, accordingly the camera automatically controls different parameters of the Sensor in different photosensitive environments, the brightness of the picture shot by the digital camera is moderate by using the control method, and the user experience is improved. The digital camera photosensitive self-adaptation control method is suitable for the digital camera.

Description

technical field [0001] The invention relates to a digital camera, in particular to photosensitive control of the digital camera. Background technique [0002] General-purpose camera photosensitive sensors are basically automatically controlled but the parameters are fixed settings. Some low-end Sensor control algorithms or defects in photosensitive components cause the camera to have the same parameter settings in different light, which also makes the image quality appear darker or brighter. Contents of the invention [0003] The object of the present invention is to provide a photosensitive adaptive control method of a digital camera, which solves the problem that the photosensitive control parameters of the current digital camera are fixed and cannot be adjusted intelligently. [0004] The present invention solves its technical problem, and the technical scheme that adopts is: [0005] A method for photosensitive adaptive control of a digital camera includes the follow...
