Embodiment 1

[0071] A method for controlling the turn-on of the supplementary light provided by the embodiment of the present application will be further described in detail below in conjunction with the accompanying drawings. The specific implementation of the method may include the following steps (the method flow is as follows: figure 2 shown):

[0072] Step S1 , the main control device sends a supplementary light control signal to the supplementary light, wherein the supplementary light control signal is used to control the turn-on of the supplementary light and the duration of the supplementary light to continue supplementary light.

[0073] The main control device sends a supplementary light control signal to the supplementary light. When the supplementary light receives the supplementary light control signal, it controls the supplementary light of the supplementary light to turn on the supplementary light, and the supplementary light determines the supplementary light according to t...

Embodiment 2

[0115] Based on the same inventive concept, the embodiment of the present application also provides a device for controlling the turning on of the fill light, see Figure 10 , the device consists of:

[0116] The sending module 1001 is configured to send a supplementary light control signal to the supplementary light, wherein the supplementary light control signal is used to control the opening of the supplementary light and the duration of the continuous supplementary light of the supplementary light;

[0117] A determining module 1002, configured to receive a feedback signal sent by a feedback device, and determine a time delay for turning on the supplementary light based on the feedback signal and the supplementary light control signal;

[0118] The adjustment module 1003 is configured to adjust the sending time of the supplementary light control signal and the duration of the supplementary light continuous supplementary light based on the delay of turning on the supplement...

Embodiment 3

[0131] The embodiment of the present application also provides an electronic device, see Figure 11 , the electronic equipment includes:

[0132] memory 1101, for storing computer instructions;

[0133] The processor 1102 is connected to the memory, and is configured to execute computer instructions in the memory, so as to execute the method according to Embodiment 1 when executing the computer instructions.

Abstract

The invention discloses a method and a device for controlling the turn-on of a light supplemental lamp. The method comprises the following steps: sending a light supplemental control signal to the light supplemental lamp, wherein, the light supplemental control signal is used for controlling the turn-on of the light supplemental lamp and the duration of the continuous light supplemental of the light supplemental lamp; receiving a feedback signal sent by a feedback device, and determining a time delay of turning on the light compensation lamp based on the feedback signal and the light compensation control signal; based on the time delay of turning on the light supplemental lamp, adjusting the transmission time of the light supplemental control signal and the time length of continuous lightsupplemental of the light supplemental lamp, so that the light supplemental lamp can perform light supplementing when the image is exposed. The invention solves the technical problem that the image quality is not high due to the incomplete exposure of the image in the prior art.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method and device for controlling turning on of a supplementary light. Background technique [0002] When the camera is taking pictures, when the ambient light is dark, in order to improve the quality of the captured image, it is necessary to perform automatic exposure through the strobe light. In the prior art, the strobe light is synchronized with the exposure of the image sensor and the supplementary light of the supplementary light. It is carried out to realize the automatic exposure of the camera during the photo taking process, that is, when the image sensor is exposed, the fill light will fill in the light, and when the image sensor is not exposed, the fill light will not fill the light. However, in the actual exposure process, the image It is difficult to synchronize sensor exposure and fill light fill light. Therefore, in order to ensure that th...
