Abstract

The invention discloses a control method. The control method comprises the following steps: obtaining the current brightness of ambient light; judging whether the current brightness is less than a preset brightness threshold; when the current brightness is less than the preset brightness threshold, controlling the combination and output of a plurality of photosensitive pixels of each photosensitive pixel unit to obtain combined pixel information, wherein the exposure time length of the plurality of photosensitive pixels of each photosensitive pixel unit is the same; obtaining a first image according to multiple pieces of combined pixel information of a plurality of photosensitive pixel units; obtaining multiple frames of first images at different exposure time lengths; and synthesizing themultiple frames of first images to serve as a high dynamic range image. By adoption of the control method disclosed by the embodiment of the invention, the image obtained by an imaging apparatus in adark light environment can also have a high dynamic range, high brightness and few noise points. In addition, the invention further discloses a control apparatus, a non-volatile computer readable storage medium, and a computer device.
