Embodiment 1

[0078] The scene detection method provided in the embodiment of the present application can be specifically applied to an intelligent mobile terminal device, and the terminal device has a camera function. For example, mobile phones, tablets, etc.

[0079] See figure 1 , which is a schematic flow diagram of a scene detection method provided in an embodiment of the present application, and the scene detection method may include the following steps:

[0080] Step S101, acquiring an image to be detected.

[0081] Step S102, dividing the image to be detected into a preset number of regions.

[0082] It should be noted that the above-mentioned preset number of values ​​can be set according to actual application needs. Specifically, the number of divided regions may be set according to the platform used. For example, when using Qualcomm platform, the preset quantity is 16*16. It should be understood that the areas of the regions are generally the same, but the purpose of the emb...

Embodiment 2

[0130] See Figure 5 , which is a schematic block diagram of a scene detection device provided in an embodiment of the present application, the device may include:

[0131] An acquisition module 51, configured to acquire an image to be detected;

[0132] Brightness value calculation module 52, for dividing the image to be detected into a preset number of regions, and calculating the average brightness value of each region;

[0133] A target area determination module 53, configured to determine the target area from the area, where the target area is a white area and / or a black area;

[0134] A grayscale information calculation module 54, configured to extract the grayscale histogram of the image to be detected based on an area other than the target area;

[0135] The scene determination module 55 is configured to determine the scene of the image to be detected according to the grayscale histogram.

[0136] In a feasible implementation manner, the above-mentioned target area ...

Embodiment 3

[0162] Figure 6 It is a schematic diagram of a terminal device provided by an embodiment of the present application. like Figure 6 As shown, the terminal device 6 of this embodiment includes: a processor 60 , a memory 61 , and a computer program 62 stored in the memory 61 and operable on the processor 60 . When the processor 60 executes the computer program 62, the steps in the above-mentioned embodiments of the scene detection method are realized, for example figure 1Steps S101 to S105 are shown. Alternatively, when the processor 60 executes the computer program 62, it realizes the functions of the modules or units in the above-mentioned device embodiments, for example Figure 5 The functions of modules 51 to 55 are shown.

[0163] Exemplarily, the computer program 62 can be divided into one or more modules or units, and the one or more modules or units are stored in the memory 61 and executed by the processor 60 to complete this application. The one or more modules o...

Abstract

The embodiment of the invention is suitable for the technical field of image processing, and discloses a scene detection method and device, terminal equipment and a computer readable storage medium, and the method comprises the steps: obtaining a to-be-detected image; dividing the to-be-detected image into a preset number of regions; determining a target area from the areas, wherein the target area is a white area and / or a black area; extracting a gray histogram of the to-be-detected image based on an area outside the target area; and determining a scene of the to-be-detected image according to the gray histogram. According to the embodiment of the invention, the scene detection accuracy can be improved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a scene detection method, device, terminal equipment and computer-readable storage medium. Background technique [0002] With the continuous development of image processing technology, the picture quality and shooting effect are getting better and better. [0003] In order to improve the shooting quality and shooting effect, it is often necessary to adjust shooting parameters according to different shooting scenes (such as backlight, forward light, non-backlight or non-smooth light). And because the intelligence of the shooting device is getting higher and higher, the current shooting device can automatically recognize different scenes, and add corresponding functions for different scenes, so as to make the shooting effect better. For example, when users use mobile phones to take pictures on a daily basis, there are often scenes with backlight or f...
