Problems solved by technology

[0003] Since there are two dominant current frequency systems in the world, 50Hz and 60Hz, terminal equipment in the prior art usually supports anti-flash screen shooting of artificial light sources at 50Hz and 60Hz based on switching the exposure meter, and the exposure meter is for different The configuration parameters of frequency light sources are relatively large (usually there are about 400 sets of configuration parameters for each frequency), so if the configuration parameters for other frequency light sources in the exposure table are increased, it will not only consume a lot of labor costs and time costs. Because of the debugging of configuration parameters, at the same time a large number of configuration parameters will occupy a larger storage space, so the feasibility is low

Embodiment 1

[0045] figure 1 It is a flow chart of an anti-flicker screen photography method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of anti-flash screen shooting in the process of full-screen shooting of different frequency light sources. This method can be implemented by the terminal, specifically through the terminal implemented in software and / or hardware.

[0046] see figure 1 , the method for taking pictures of the anti-flash screen comprises the following steps:

[0047] S110. Trigger an exposure parameter adjustment mode when it is detected that there is a flicker phenomenon in the preview image.

[0048] Wherein, the shooting terminal in this embodiment may be, for example, a camera, a mobile phone equipped with a camera, a computer, a tablet computer, or a driving recorder and other terminals. Among them, when the shooting terminal is full-screen shooting light sources of different frequencies, there may be a flickering...

Embodiment 2

[0069] On the basis of the above-mentioned embodiments, this embodiment provides another method for determining the exposure time parameter, specifically: in the exposure parameter adjustment mode, it also includes: traversing the preset frequency parameter interval, and judging the current Whether there is a flicker phenomenon in the preview screen under the frequency parameter; if not, use the current frequency parameter as the target frequency parameter, determine the exposure time parameter according to the target frequency parameter obtained through traversal, and shoot according to the exposure time parameter. This embodiment has the same inventive concept as the above-mentioned embodiment, and explanations of terms that are the same as or corresponding to those of the above-mentioned embodiment will not be repeated in this embodiment.

Abstract

The embodiment of the invention discloses an anti-splash shooting method and device, a terminal and a storage medium. The method comprises the steps of: when detecting that a preview image has a splash phenomenon, triggering an exposure parameter regulation mode; in the exposure parameter regulation mode, receiving a target frequency parameter; and according to the target frequency parameter, determining an exposure time parameter, and according to the exposure time parameter, carrying out shooting. According to the anti-splash shooting method and device, the terminal and the storage medium, which are provided by the embodiment of the invention, the splash phenomenon in the process of carrying out full-screen shooting on light sources with different frequencies is eliminated.

Description

technical field [0001] Embodiments of the present invention relate to image acquisition technology, and in particular to a method, device, terminal and storage medium for taking pictures of an anti-flash screen. Background technique [0002] At present, when a terminal device is shooting an artificial light source, since the artificial light source is powered by alternating current, and the energy of the alternating current changes periodically in the form of a sine wave, and the terminal device performs exposure in units of pixel rows during the process of capturing images, so when the terminal device If the exposure time does not satisfy the integer multiple of the AC power cycle, the brightness of the image captured by the terminal device will change periodically with the number of pixel rows, making the captured image appear to have strips flickering on the surface, that is, a flickering screen occurs phenomenon (also known as flicker phenomenon). [0003] Since there a...
