Embodiment 1

[0058] see figure 2 , which shows a shooting parameter adjustment method provided by an embodiment of the present invention, the method can be applied to a mobile terminal with a shooting function, and the specific structure of the mobile terminal is as follows figure 1 The structure shown is an atypical example, the method could include:

[0059] S201: Count the number of color components corresponding to each color channel in the collected image; wherein, the collected image is taken based on initial shooting parameters;

[0060] It should be noted that when the camera of the mobile terminal is shooting, it will capture the image of the subject according to the initial shooting parameters, cache the captured image through the memory, and display it on the display panel as a preview image. The initial shooting parameters may be the default shooting parameters of the mobile terminal, the shooting parameters used by the mobile terminal in the previous shooting, or the shootin...

Embodiment 2

[0086] Based on the same inventive concept of the foregoing embodiments, see Figure 5 , which shows a detailed flow of a shooting parameter adjustment method provided by an embodiment of the present invention. In this embodiment, the flow is applied to a mobile terminal, and the shooting object is a red flower. The flow may include:

[0087] S501: Collect the object to be photographed according to the initial shooting parameters, and obtain the collected image;

[0088] The initial shooting parameters may be the default shooting parameters of the mobile terminal, the shooting parameters used by the mobile terminal in the previous shooting, or the shooting parameters optimized by the mobile terminal according to the shooting parameters used in historical shooting. The embodiment does not repeat this.

[0089] S502: Count the number of color components corresponding to each color channel in the collected image;

[0090] The color channels include: red (R, Red), green (G, Gree...

example 1

[0101] When the ratio exceeding the first threshold exceeds the preset second threshold, the saturation of the color component corresponding to the solid-color object image is increased according to the initial shooting parameters.

[0102] Taking safflower as an example, when it is determined that the image of a pure-color object is red, the initial saturation of the red component in the initial shooting parameters can be increased, so that the color of the safflower in the image can be made more vivid; when the image of a pure-color object is determined For other colors, the initial saturation of other color components can also be increased accordingly.

Abstract

The embodiment of the invention discloses a shooting parameter adjusting method and device. The method may includes the following steps: counting the color component number corresponding to each color channel in a collected image, wherein collected image is captured on the basis of initial shooting parameters; on the basis of the color component number and the total number of pixels of the collected image, determining whether the collected image is a pure color object image; and if the collected image is a pure color object image, adjusting the initial shooting parameters on the basis of the pure color object image according to preset adjusting strategies. In this way, shooting parameters can adapt to shooting scenes of pure color objects, and shooting effects are improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for adjusting shooting parameters. Background technique [0002] With the rapid development of electronic technology, the functions of mobile terminals such as smart phones and tablets are diversified. Users can not only use mobile terminals to realize basic communication functions such as calling and sending text messages, but also perform operations such as taking pictures through mobile terminals. [0003] In the process of photographing an object, the mobile terminal usually adopts default photographing parameters, such as parameters such as saturation and brightness, for photographing. The default shooting parameters are mostly set for common shooting scenes, such as landscapes, people and other colorful subjects. When the default shooting parameters are used to shoot a solid-color object, such as a red flower, since the shooting object ...
