Method and device for intelligently switching to HDR mode of camera

Abstract

The invention relates to a method and device for intelligently switching to an HDR mode of a camera. Computer program instructions are used for controlling a computer to complete the camera method for intelligently switching the HDR mode through establishing of a functional module framework, and the computer program instructions are stored in computer readable storage media. The method includes the steps that the duty ratio of pixels of which the brightness value is smaller than a preset low brightness value and the duty ratio of pixels of which the brightness value is larger than a preset high brightness value in an image of a current scene of a camera are estimated, and switching to the HDR mode can be achieved only when the duty ratio of the pixels of which the brightness value is smaller than the preset low brightness value is larger than a preset low brightness ratio threshold value and the duty ratio of the pixels of which the brightness value is larger than the preset high brightness value is larger than a preset high brightness ratio threshold value. In combination with the characteristics of the HDR mode, the estimation of the duty ratio of the pixels of which the brightness value is smaller than the preset low brightness value and the duty ratio of the pixels of which the brightness value is larger than the preset high brightness value in the image of the current scene can really reflect brightness distribution conditions of the actual scene, and accurately judge whether or not switching to the HDR mode needs to be performed to take photos.

Description

technical field [0001] The invention relates to a method for intelligently switching an HDR mode of a camera. The method is completed by establishing a functional module framework and controlling a computer system by computer program instructions, and the computer program instructions are stored in a computer-readable storage medium. Background technique [0002] When using the normal mode of the camera to take pictures, if the difference between the light and dark of the current scene is too large, the photos taken are likely to be too bright in bright areas or too dark in dark areas, thus losing the details of bright areas or dark areas and affecting the photos At this time, if you want to retain as many details as possible in the photo, you need to use HDR (High-Dynamic Range, high dynamic range) mode to take pictures, because the photos taken in HDR mode are much better than those taken in normal mode , can provide more dynamic range and image details. The principle of...

Problems solved by technology

[0003] Today's cameras include a variety of camera modes, including HDR mode, but users need to manually switch camera modes when taking pictures. Most ordinary users do not have professional photography knowledge and skills, and these ordinary users do not know which scenes should be Only HDR mode can be used to take good photos, so manual switching of HDR mode is not smart enough, and it is not convenient for ordinary users to use
