Control method for achieving low power consumption of camera and camera

Abstract

The invention discloses a control method for achieving low power consumption of a camera, and the camera is provided with a double-lens module, and the method comprises the steps: carrying out the statistics of the brightness of a visible light image of a current image, and controlling a first lens module to be in a working state and a second lens module to be in a dormant state when the brightness of the visible light image is greater than a switching threshold; when the brightness of the visible light image is smaller than the switching threshold value, controlling the first lens module to be in a dormant state and the second lens module to be in a working state; when the brightness of the visible light image is equal to the switching threshold value, controlling the source lens module in the working state at present to be switched to the target lens module in the dormant state at present; and triggering the target lens module to enter a working state from a dormant state after the image acquisition control parameters of the source lens module are adjusted according to a condition that a current source image from the source lens module reaches an image expectation as a target. The effect of image acquisition before and after switching is ensured, the switching is fast, and the overall power consumption of the camera is reduced.

Description

technical field [0001] The invention relates to the field of camera control, in particular to a control method for realizing low power consumption of the camera. Background technique [0002] In some areas where wired power supply is inconvenient, the camera is usually powered by a battery or solar energy plus a rechargeable battery. Due to battery cost and capacity limitations, the camera needs to be able to operate with low power consumption as a whole. [0003] see figure 1 as shown, figure 1 It is a hardware schematic diagram of existing camera control. Under the control of the main system chip (SOC) and / or microcontroller (MCU), the camera lens module outputs the image data collected by the image sensor through the lens assembly to the main system chip (SOC), so that the main system chip can perform image processing. Processing, image analysis, target detection, target analysis, data network transmission and other functions. In order to enable the camera to operate ...

AI Technical Summary

Problems solved by technology

[0004] The advantage of the existing low-power control scheme is that the battery life can be extended by reducing the frequency of MCU triggering high-power devices, but this also leads to unsatisfied image acquisition requirements

For example, when the trigger threshold of the sensor detection signal is set too low, it will be difficult to obtain the best posture of the target, including but not limited to the situation where the target is too far away, the target is in the background, the target is sideways, etc., and the image cannot be collected
