Abstract

An imaging control method, device, electronic device and computer readable storage medium, wherein the method is applied to an imaging apparatus comprising an array of pixel units composed of a plurality of photosensitive pixel units, each photosensitive pixel unit comprising a short exposure pixel, a medium exposure pixel and a long exposure pixel whose exposure time increases in turn. The methodcomprises determining a brightness level of ambient brightness; determining a target pixel from the short exposure pixel, the medium exposure pixel and the long exposure pixel of each photosensitivepixel unit according to the brightness level of the ambient brightness; controlling target pixels determined in each photosensitive pixel unit to output original pixel information; imaging according to the original pixel information output from each photosensitive pixel unit. The method can retain more effective information in the photographed image, improve the signal-to-noise ratio of the photographed image, and enhance the brightness of the photographed image, thereby improving the imaging effect and the imaging quality, and improving the photographing experience of the user.

Description

technical field [0001] The present application relates to the technical field of electronic devices, and in particular, to an imaging control method, apparatus, electronic device, and computer-readable storage medium. Background technique [0002] With the continuous development of terminal technologies, more and more users use electronic devices to capture images. In a backlight scene, when the user takes a selfie with the front camera of the electronic device, since the user is between the light source and the electronic device, it is easy to cause insufficient exposure of the face. If you adjust the exposure to brighten the face, you will overexpose the background area, and you will not even be able to see the scene of the selfie. [0003] In the prior art, a suitable pixel unit in the pixel unit array is selected to participate in imaging through a high dynamic range (High Dynamic Range, HDR for short) technology. [0004] However, in some shooting scenarios, the image...
