Embodiment Construction

[0046] In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0047] Unlike the prior art which divides the entire image processing process into two parts, format conversion and scaling, and performs two interpolation operations, the present invention integrates data format conversion and image scaling into one interpolation operation, thus reducing the amount of calculation.

[0048] Assume that the size of the Bayer data format image before scaling is M×N, and the size of the RGB data format image after scaling is M′×N′. Then, each pixel in the image in Bayer data format before scaling has only one primary color color value; since no interpolation operation is performed, each pixel in the image in RGB data format after scaling does not contain the color related to the image before scaling value, the color values ​​of the three primary colors of e...

Abstract

The zooming image converting method includes the following steps: determining the corresponding point in the original image of each pixel point in the zoomed image; selecting the interpolating data point in the original image based on the corresponding point; and apply the interpolating data point in interpolating calculation to obtain the color value of each pixel point in zoomed image. The present invention has reduced interpolating calculation amount in image processing process, lowered calculation complexity, raised image processing speed and no degradation of image quality.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image conversion method for realizing scaling. Background technique [0002] In digital cameras, cameras and other equipment, the Bayer sensor usually collects images, discretizes the images into pixels, and uses a certain primary color to represent the color value of the pixels. The Bayer sensor adopts the RGB (red, blue, green) color model, which includes three primary colors of R (red), G (green), and B (blue). In the data format of the Bayer sensor, each pixel only collects the color value of one of the three primary colors R, G, and B, as shown in Figure 1(a) to Figure 1(d) is the data format of the Bayer sensor. Because in the coordinate system shown in Figure 1, the color values ​​of pixels are arranged in different ways in the initial row, there are four different data arrangement formats as shown in Figure 1(a) to Figure 1(d). Among them, the pixel color type of the ...
