Abstract

The invention discloses a detection method, which is used for detecting whether an object in a scene moves. First, the sampling interval frame number is calculated according to the frame rate of the preview image output by the imaging device, and the ratio of the sampling interval frame number to the frame rate is a predetermined time. Then, according to the frame number of the sampling interval, two frames of preview images before and after are extracted as sample images. Finally, two frames of sample images before and after the two frames of preview images are processed to determine whether the subject moves. The invention also discloses a control method, a detection device, a control device and an electronic device. By judging whether the subject on the sample image moves, the time interval between the sample images can be adjusted, and then the exposure time can be calculated according to the time interval, and a clearer image can be taken by adopting an appropriate exposure time.

Description

technical field [0001] The invention relates to the field of imaging, in particular to a detection method, a control method, a detection device, a control device and an electronic device. Background technique [0002] When taking pictures, if the subject in the scene is moving, it is easy to cause blurred images. Therefore, detecting whether the subject in the scene is moving can be used to assist imaging, but there is no ideal detection method at present. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the present invention proposes a detection method. . [0004] The detection method in the embodiment of the present invention is used to detect whether the subject in the scene moves, and the detection method includes: [0005] Calculation step, calculating the sampling interval frame number according to the frame rate of the preview image output by the imag...
