Embodiment Construction
[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the following embodiments will specifically illustrate the cutting device provided by the present invention in conjunction with the accompanying drawings.
[0033] Such as figure 1 As shown, it is a flow chart of the supplementary light method for camera imaging, and the supplementary light method provided by this embodiment includes the following steps:
[0034] S1: Measure the light of the environment where the camera is located, and obtain the fill light command;
[0035] The supplementary light command is based on the ambient light metering. When the illuminance of the scene is lower than the preset threshold, the control unit lights up the supplementary light and performs strobe supplementary light at a certain frequency; if the current depth camera is activated, the control power supply follows the Light up the structured light source a...

The invention provides a light supplementing method for camera imaging, and the method comprises the following steps: S1, carrying out the light measurement of an environment where a camera is located, and obtaining a light supplementing instruction; S2, determining a light supplementing frame flash period according to the current frame exposure period; s3, starting to lighten a structured light source according to the light supplementing instruction obtained in the step S1; s4, after the exposure of the current frame in one frame exposure period is finished, turning off a structured light source according to the light supplementing instruction obtained in the S1; and S5, repeating the steps S3 and S4 according to the light supplementing frame flash period obtained in the step S2. According to the light supplementing method for camera imaging provided by the invention, under the condition that the frame rate output is not changed, the light supplementing duration is adjusted by adjusting the exposure duration; that is to say, the exposure duration is shortened, the frame interval is increased, the light supplementing duration is correspondingly reduced, the power consumption is further reduced, and the service life of the light supplementing device is prolonged.
Description
technical field [0001] The invention relates to the technical field of image acquisition, in particular to a method for supplementing light for camera imaging. Background technique [0002] The role of the image sensor is to convert the optical image into a digital signal, which can then be processed by an image signal processor. Two image sensor types widely used in cameras are scientific-grade charge-coupled devices (CCDs) and scientific-grade complementary metal-oxide semiconductors (CMOS). With the improvement of CMOS process, the development of related technologies and cost advantages, more and more CMOS image sensors are adopted by various imaging devices. [0003] As a photosensitive component, the CMOS image sensor needs to be supplemented with light in order to obtain clear and usable images or image sequences, and to improve the imaging effect under low light or dark conditions. If it is to obtain a single image, the flash light is generally used to fill the scen...
