Embodiment Construction

[0022] The general inventive idea of ​​the present invention is to provide an image processing method and an image processing device for a portable terminal. When the hardware configuration of the portable terminal is not high and the shutter speed is not fast enough, the image captured by the camera is processed by software. Adjust the brightness of individual images to improve the imaging quality of images captured at night. Specifically, first capture the first image; then adjust the brightness of pixels in the first image whose grayscale value is lower than the grayscale threshold to generate a second image, and then synthesize the first image and the second image, Generate a third image. Through the above method, a high-quality third image is obtained, and the goal of improving the imaging quality of the night shot image is achieved without improving the hardware configuration of the portable terminal and when the shutter speed of the portable terminal is not fast enough....

Abstract

The invention provides an image processing method and image processing apparatus for a portable terminal. The image processing method for the portable terminal comprises: based on brightness improvement of a single image, capturing a first image, through adjusting the brightness of a pixel whose grayscale value is lower than a grayscale threshold in the first image, generating a second image, and synthesizing the first image with the second image to generate a third image. By using the image processing method and image processing apparatus for the portable terminal, the hardware configuration of the portable terminal does not have to be improved, the problem of over high requirement for shutter speed during continuous shooting processing of multiple images is also solved, the hardware cost of the portable terminal is decreased, and the imaging quality of an image shot at night can be well improved.

Description

technical field [0001] The present invention relates to image processing technology, in particular to an image processing method and image processing device for a portable terminal. Background technique [0002] In the absence of professional photographic equipment, when users use portable terminals (such as mobile phones) to take pictures at night or in dark indoor environments, the resulting images often have problems such as blurring, excessive noise, and poor brightness and contrast. [0003] In order to solve the above problems, the following two technical solutions are generally adopted in the prior art: [0004] 1) Improve the imaging quality of night shots by improving the hardware configuration, such as configuring a camera with more than 8 million pixels, making the aperture reach F2.0, and equipped with an independent professional ISP (image signal processing) processing chip. [0005] 2) Improve the image quality of night shots by continuously shooting, aligning...
