Abstract

The invention discloses a control method, which is used for controlling an imaging device to use a contrast focus mode for video recording. The imaging device includes a focusing lens and a display. The control method includes: an acquisition step, a processing step and a control step. The acquiring step acquires multiple videos of predetermined duration during the focusing process. The processing step processes the video to calculate the decrease in sharpness of the current video image relative to the previous frame of video image. The control step controls the display to play the previous video when the sharpness decline is greater than a predetermined threshold. The control method, control device and electronic device in the embodiments of the present invention, when using the contrast focus mode to record video, buffer the video of a predetermined duration, and judge that the focusing lens will start to roll back when it is detected that the definition of the video image begins to decline, and then When controlling the display not to play the current video but to play the cached video, the user will not preview the video in the focusing process, which improves the user's visual experience.

Description

technical field [0001] The invention relates to imaging technology, in particular to a control method, a control device and an electronic device. Background technique [0002] When using the contrast focus mode for video recording, after the focus lens passes the focus position, the contrast of the image decreases, so the focus lens needs to be pushed back. However, pushing the focus lens back will cause the preview screen to jump, affecting the user experience. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention needs to provide a control method, a control device and an electronic device. [0004] The control method in the embodiment of the present invention is used to control the imaging device to perform video recording using a contrast focus mode, the imaging device includes a focusing lens and a display, and the control method includes the following s...
