Embodiment Construction

[0084] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0085] Such as figure 2 As shown, according to an image processing method S20 of an embodiment of the present invention, the method includes:

[0086] S201: Obtain status information of a terminal device.

[0087] The state information can be directly collected by the sensor on the terminal device, such as the information collected by the gravity sensor or gyroscope on the terminal device, or it can be obtained after calculation or other processing based on the above information information. Terminal devices may include devices such as smartphones, tablets, and laptops.

[0088] In a possible implementation, the gravity sensor can be used to measure the acceleration value caused by gravity, and the acceleration value can be used as the state information; in another possible implementation, the gyroscope can be used to measure whe...

Abstract

The embodiment of the invention discloses an image processing device. The device comprises an acquisition module, an image shooting module, a mode selection module and a processing module, wherein theacquisition module is used to acquire state information of terminal equipment; the image shooting module is used to acquire shooting scene information of the terminal equipment; the mode selection module is used to determine an image processing mode according to the state information and the shooting scene information; the image shooting module is further used to acquire an image to be displayed;and the processing module is used to process the image to be displayed according to the image processing mode to obtain a processed image. The embodiment of the invention further discloses an image processing method. According to the image processing method and device disclosed by the embodiment of the invention, different image processing modes can be selected according to determination resultsof the state information of the terminal equipment and the shooting scene information; and a better synthetic image can be obtained by using different exposure values and different image fusion modes.

Description

technical field [0001] The present application relates to the technical field of photographing, and more specifically, to an image processing method and device. Background technique [0002] Night scene shooting has always been a difficult problem for mobile phone shooting, because the brightness difference between the light source and the non-light source area is too large, which has a very high dynamic range; it is easy to have high-brightness overexposure and low-brightness underexposure at the same time through single-frame shooting; on the other hand , because the brightness of night scenes is generally relatively low, under the limited exposure time, there will be relatively high noise for non-high dynamic scenes, and it is difficult to obtain high-quality images; For high dynamic range scenes, such as outdoor backlit scenes on sunny days, night scene portrait scenes, etc., a single image can only capture part of the information of the high dynamic range scene, or ther...
