Embodiment Construction
[0032] In order to make the technical means, creative features, achieved goals and effects of the present invention easy to understand and understand, the following embodiments describe the cutting device provided by the present invention in detail with reference to the accompanying drawings.
[0033] like figure 1 As shown, it is a flow chart of a method for supplementing light for camera imaging, and the method for supplementing light provided by this embodiment includes the following steps:
[0034] S1: Meter the environment where the camera is located, and obtain fill-light instructions;
[0035] The fill light command is metering according to the ambient light. When the illumination of the scene is lower than the preset threshold, the control unit will turn on the fill light and perform strobe fill light according to a certain frequency; if the current depth camera is activated, the control power supply will be The structured light source is lit at a certain frequency, a...

The present invention provides a method for supplementing light for camera imaging, which includes the following steps: S1: perform light metering on the environment where the camera is located, and obtain a supplementary light instruction; S2: determine a supplementary light frame flashing period according to the current frame exposure period; S3: according to The supplementary light command obtained by S1 starts to turn on the structured light source; S4: After the current frame is exposed within one frame exposure period, the structured light source is turned off according to the supplementary light command obtained by S1; S5: The supplementary light frame flashes according to S2 cycle, repeat the above S3 and S4. The supplementary light method for camera imaging provided by the present invention adjusts the supplementary light duration by adjusting the exposure duration when the frame rate output remains unchanged; that is, by shortening the exposure duration and increasing the frame interval at the same time, the supplementary light duration is correspondingly reduced. , thereby reducing power consumption and improving the life of the supplementary light device.
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 types of image sensors that are widely used in cameras are scientific-grade charge-coupled devices (CCDs) and scientific complementary metal-oxide-semiconductor (CMOS). With the improvement of CMOS technology and the development of related technologies and cost advantages, CMOS image sensors are more and more adopted by various imaging devices. [0003] As a photosensitive component, CMOS image sensor needs to be supplemented with light in order to obtain a clear and usable image or image sequence in order to improve the imaging effect under low light or dark conditions. If a single image is to be obtained, a flash light is generally used to f...
