Embodiment 1

[0036] Such as figure 1As shown, it is a schematic flowchart of a scene image processing method provided by an embodiment of the present invention, and the method specifically includes the following steps:

[0037] Step 101: Determine a first combined area and a second combined area in the pre-shot image according to the gray value of each pixel in the pre-shot image of the scene to be shot.

[0038] Wherein, the first combined area includes at least one highlighted area, and other areas in the pre-shot image except the first combined area are the second combined area.

[0039] Specifically, after determining the shooting scene, use the pre-shooting function of the shooting device to obtain a pre-shot image buffered in the shooting device, and obtain the gray value of each pixel in the pre-shot image; it should be noted that, The gray value may be an integer or a non-integer, which is not limited in the present invention. However, in the embodiments of the present invention,...

Embodiment 2

[0074] Generally speaking, the scene image processing device is set in a device with an image capture function, and a simple operation trigger is performed by establishing a connection with the image capture device; or the capture function is integrated into the scene image processing device, In a word, the present invention does not limit the specific structure of the scene image processing device.

[0075] Such as Figure 7 As shown, it is a schematic structural diagram of a scene image processing device provided by an embodiment of the present invention, and the device may include:

[0076] The area determination unit 201 is configured to determine a first combined area and a second combined area in the pre-shot image according to the gray value of each pixel in the pre-shot image of the scene to be shot, wherein the first combined area includes At least one highlighted area, and other areas in the pre-shot image except the first combined area are the second combined area....

Abstract

The invention discloses a scene image processing method and device. The scene image processing method mainly comprises the steps that first exposure and second exposure are determined by obtaining grey levels of all pixel points in a pre-shot image of a shot scene and according to a determined first combined area and a determined second combined area, the grey levels of all the pixel points in a first image area, corresponding to the first combined area, in a first image obtained by carrying out shooting at the first exposure and the grey levels of all the pixel points in a second image area, corresponding to the second combined area, in a second image obtained by carrying out shooting at the second exposure are adjusted respectively, the adjusted two image areas are spliced, and a scene image is obtained. Thus, the problem of excessive exposure or insufficient exposure of the image due to the large brightness and darkness difference in the shot scene is solved, and the scene details of the shot scene are reserved to the maximum extent; meanwhile, the brightness relation between a bright area and a dark area in the shot scene is restored to the maximum extent, and the quality of the scene image is made to be better.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a scene image processing method and device. Background technique [0002] With the advancement of technology and the development of the times, users have higher and higher requirements for image quality, especially for high-performance experience of devices with image capture functions. [0003] However, most of the devices with image capture function are designed and used according to the most common lighting environment. For example, the most common digital cameras can be By adjusting the aperture, shutter and other attribute settings for optimal shooting, high-quality image effects can be obtained. [0004] However, in a shooting scene with a large difference between light and dark, for example: a building covered with neon lights at night, because the neon lights of the building are brighter, the night is darker, so when the property settings of the digital ...
