Abstract

The invention provides a video recording system control method and device, and the method comprises the steps: determining whether the state of a video recording system needs to be switched or not; and under the condition that it is determined that state switching needs to be carried out, switching the video recording system from the current state to a target state. According to the scheme, the video encoder and the external storage device are controlled to be in the closed state under the condition that the video recording function is not triggered, and the video encoder and the external storage device are started only under the condition that the video recording function is triggered, so that power consumption is reduced. The image sensor and the image signal processing unit are controlled to be in the working state all the time, so that image data within the preset time length can be obtained, and the expected video content is prevented from being missed.

Description

technical field [0001] The invention relates to the technical field of equipment control, in particular to a video recording system control method and device. Background technique [0002] Considering that the recording equipment in many scenes has a built-in power supply, limited by the capacity of the battery, it is generally impossible to record for a long time. For this reason, the general operation mode is to turn on the video recording only when the video recording is required, and usually control it to be in the non-recording state as much as possible to save power consumption. [0003] However, there is a problem in this mode of operation, that is, for the user, in many scenarios, it is impossible to predict whether the video recording needs to be turned on for video recording at the next moment. In this way, when there is an unexpected situation or more exciting content, the user will often miss a better recording opportunity if he turns on the video recording func...
