Problems solved by technology

[0002] When shooting images, if the subject is in a backlit scene, in order to obtain a better visual effect of the subject, it is generally necessary to increase the brightness of the subject, which will easily cause the background behind the subject to be overexposed, so that the image cannot clearly display the entire shooting scene

Abstract

The invention discloses an acquisition method. The acquisition method comprises the steps that whether or not a corresponding scene of a scene image is a backlight scene is judged; if yes, whether ornot the current brightness of the environment is higher than a preset brightness threshold is judged; if the current brightness is higher than the preset brightness threshold, whether or not an imaging device is stable is judged; when the imaging device is not stable, a pixel unit array is controlled to output multiple original pixel information of different exposure times; multiple merged pixel information is obtained according to the original pixel information at the same exposure time in the same pixel unit; and a high dynamic range image is output according to the multiple merged pixel information. The invention further discloses an acquisition device, a computer readable storage medium and computer equipment. According to the acquisition method and device, the computer readable storage medium and the computer equipment, the high dynamic range image is obtained according to the multiple merged pixel information of the same pixel unit, background overexposure is avoided while the subject brightness is guaranteed, and the whole shoot scene is clearly displayed.
