A camera processing method and terminal device

Abstract

The embodiment of the invention discloses a photographing processing method and a terminal device, which are applied in the technical field of mobile communication. The method is applied to a terminal device with a camera, wherein the camera includes an image sensor, and the image sensor includes a photosensitive pixel array and a filter disposed on the photosensitive pixel array. The method includes: acquiring a preview image collected by the camera, and detecting Whether there is noise or glare in the preview image; if it exists, it is judged whether the noise intensity in the preview image exceeds the preset noise intensity threshold and / or whether the glare intensity in the preview image exceeds the preset glare intensity threshold; if If it exceeds, adjust the thickness of the optical filter corresponding to the imaging pixel point that generates the noise or glare to change the amount of light entering the image sensor; control the camera to capture the scene and generate a photo. By implementing the embodiments of the present invention, the noise and / or glare phenomenon in the image can be reduced, and the imaging quality of the image during the photographing process can be improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a photographing processing method and a terminal device. Background technique [0002] With the continuous improvement of camera pixels in terminal devices such as smartphones and tablet computers, more and more people are keen to use smartphones to take pictures, followed by the gradual increase in user requirements for cameras in smartphones, and This improvement is mainly reflected in the imaging effect of the camera. Due to factors such as the intensity of the light source and the lens of the camera, images captured by the camera often produce noise and / or glare. [0003] When shooting in a low light source (i.e. in a dark place), due to the low brightness in a dark place, the gain and shutter values ​​can easily reach the maximum, that is, the amount of light entering reaches the maximum. Due to the fixed aperture, the amount of light entering cannot be ...

Problems solved by technology

[0003] When shooting in a low light source (i.e. in a dark place), due to the low brightness in a dark place, the gain and shutter values ​​can easily reach the maximum, that is, the amount of light entering reaches the maximum. Due to the fixed aperture, the amount of light entering cannot be increased, and the signal The signal-to-noise ratio is relatively low, and after a large multiple of gain amplification, the image is prone to noise

Conversely, when the intensity of the light source is high (i.e., a place with strong light), since the incoming light is very bright, the amount of incoming light cannot be effectively reduced through the shutter, and the generated image is prone to glare (whitening of the image caused by strong light, forming halos) Phenomenon), reducing the contrast, making the image look like a layer of gray

However, in use, it is found that controlling the exposure by adjusting the gain and the shutter cannot effectively reduce the noise and / or glare in the image, which reduces the imaging quality of the image during the photoshoot
