Problems solved by technology
However, in this image acquisition method, three different exposure times are calculated based on the histogram of the entire image. Since the brightness of the entire image is not linear, it is impossible to directly use the histogram of the entire image to calculate the three exposure times. Achieve better AE convergence

The invention discloses a control method, a control device, imaging equipment, computer equipment and a nonvolatile computer readable storage medium. The control method comprises the steps of: controlling long exposure pixels, intermediate exposure pixels and short exposure pixels to expose respectively through initial long exposure parameters, initial intermediate exposure parameters and initialshort exposure parameters, so that long exposure original pixel information, intermediate exposure original pixel information and short exposure original pixel information are obtained, calculating correction long exposure parameters according to the long exposure original pixel information, calculating correction intermediate exposure parameters and correction short exposure parameters accordingto the correction long exposure parameters, and controlling a pixel unit array to expose according to the correction long exposure parameters, the correction intermediate exposure parameters and the correction short exposure parameters, so that a high dynamic range image is output. According to the control method, the control device, the imaging equipment, the computer equipment and the nonvolatile computer readable storage medium in the embodiment of the invention, an image is shot after long, intermediate and short exposure times of the pixel unit array are corrected; and thus, the imaging effect of the image is better.
Description
technical field [0001] The present invention relates to the field of imaging technology, in particular to a control method, a control device, an imaging device, a computer device and a non-volatile computer-readable storage medium. Background technique [0002] Currently, high dynamic range images can be captured by setting multiple pixels in an image sensor to be exposed synchronously at three different exposure times. However, in this image acquisition method, three different exposure times are calculated based on the histogram of the entire image. Since the brightness of the entire image is not linear, it is impossible to directly use the histogram of the entire image to calculate the three exposure times. Achieve better AE convergence. Contents of the invention [0003] Embodiments of the present invention provide a control method, a control device, an imaging device, a computer device, and a non-volatile computer-readable storage medium. [0004] The control method ...
