Embodiment 1

[0037] The shooting parameter setting method provided by Embodiment 1 of the present application is described below, please refer to the attached figure 1 , the shooting parameter setting method includes:

[0038] In step S101, when it is detected that the preview image of the camera flickers, the flicker frequency of the preview image is calculated;

[0039] If the various steps in the embodiment of the present application are applied to a terminal device (for example, a mobile phone), then in step S101, the terminal device can continuously detect whether the preview screen of the camera flickers (for example, by detecting the flickering of the preview screen of two adjacent frames). Whether there is a large difference in brightness to determine whether flickering occurs in the preview image), once flickering is detected, the terminal device calculates the flickering frequency of the preview image. At present, there are many methods to calculate the flickering frequency of t...

Embodiment 2

[0058] Another shooting parameter setting method provided by Embodiment 2 of the present application is described below, please refer to the attached figure 2 , the shooting parameter setting method includes:

[0059] In step S201, when it is detected that the preview image of the camera flickers, the flicker frequency of the preview image is calculated;

[0060] In step S202, the frequency of the charging signal at the location of the above-mentioned camera is acquired;

[0061] In step S203, the flicker frequency of the light source is calculated based on the flicker frequency of the preview screen, the charging signal frequency, and the flicker frequency calculation formula of the light source, wherein the flicker frequency calculation formula of the light source is:

[0062]

[0063] Among them, f light is the flicker frequency of the above light source, f charge is the frequency of the charging signal above, f preview is the flickering frequency of the preview scr...

Embodiment 3

[0084] Embodiment 3 of the present application provides a shooting parameter setting device. For the convenience of description, only the parts related to the present application are shown, such as image 3 The shooting parameter setting device 300 shown includes:

[0085] The preview image flicker calculation module 301 is used to calculate the flicker frequency of the preview image when it is detected that the preview image of the camera flickers;

[0086] A charging frequency acquisition module 302, configured to acquire the frequency of the charging signal at the location of the above-mentioned camera;

[0087] The light source flicker frequency calculation module 303 is configured to calculate the flicker frequency of the light source based on the flicker frequency of the preview image, the charging signal frequency, and the calculation formula of the light source flicker frequency, wherein the light source flicker frequency calculation formula is:

[0088]

[0089] A...

Abstract

The present application provides a shooting parameter setting method, a setting device, a terminal device and a readable storage medium. The method includes: when it is detected that the preview image of the camera flickers, calculating the flicker frequency of the preview image; calculating the flicker frequency of the light source based on the flicker frequency of the preview image and the frequency of the charging signal where the camera is located; if the If the exposure time of the camera is not an integer multiple of the flickering period of the light source, the exposure time is set to be an integer multiple of the flickering period of the light source, and the flickering period is the reciprocal of the flickering frequency of the light source. The present application can solve the technical problem that the flicker phenomenon cannot be eliminated for a special type of light source in the existing technical solution.

Description

technical field [0001] The present application belongs to the field of computer technology, and in particular relates to a shooting parameter setting method, a shooting parameter setting device, terminal equipment and a computer-readable storage medium. Background technique [0002] In order to avoid the flicker phenomenon in the camera preview screen, it is necessary to set the exposure time of the camera to an integer multiple of the flicker period of the light source. [0003] At present, the common method of setting the exposure time is: obtain the location of the camera through geographic location positioning, and according to the location of the camera, determine twice the frequency of the charging signal at the location of the camera as the flickering frequency of the light source, and adjust the exposure time of the camera as determined Integer multiples of the light source flicker period (reciprocal of the determined light source flicker frequency). For example, th...
