Abstract

An embodiment of the invention discloses a photograph generating method which comprises the following steps: a first original image, a second original image and a third original image that are respectively taken via a first camera, a second camera and a third camera are obtained; only red color information, green color information and blue color information are respectively stored in the first original image, the second original image and the third original image that are taken; parameters of the first original image, the second original image and the third original image that are obtained are adjusted; a first intermediate image, a second intermediate image and a third intermediate image are obtained and are subjected to combining operation, and therefore a photograph is generated. The embodiment of the invention also provides a corresponding mobile terminal. Via use of the photograph generating method provided in the embodiment of the invention, color noisy points can be reduced; definition, color restoration and photograph brightness are not affected.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a photo generation method and a mobile terminal. Background technique [0002] The current cameras are all on the same module, mainly composed of color filter and photosensitive chip. Such as figure 1 As shown, each pixel of the camera module sensor corresponds to a Color filter, such as figure 2 As shown, the filter is distributed according to the Bayer pattern of the Bayer data arrangement. The Color filter filters the light passing through each pixel pixel so that each pixel can only sense red (R), green (G) or blue (B) signal, and then convert the electrical signal into a digital signal through an analog-to-digital AD converter. The data we get at this time is the unprocessed data RAW DATA (same as figure 2 Bayer data shown). Therefore, in the RAW DATA format, each pixel only stores the data of a monochrome signal (one of R, G, and B). To restore a three-color signal, a ...
