Problems solved by technology

[0021] From the image enlargement principle of bilinear interpolation shown in formulas (1) to (5), it can be seen that in the process of calculating the gray value of the new pixel inserted in the target image, multiple floating-point multiplications and floating-point multiplications are required. In this way, a large number of multiplier resources will be required to realize the enlargement of the target image when implemented in the image enlargement device, so it will consume a large amount of multiplication when the current bilinear interpolation method is used to enlarge the target image device resources, resulting in the tension of the system resources of the image magnification device

[0128] Such as Figure 11 As shown, the difference between this embodiment and the above-mentioned embodiment is that the linear interpolation in the horizontal direction is performed first to complete the enlargement in the horizontal direction, and then the linear interpolation in the vertical direction is performed to complete the enlargement in the vertical direction. The basic principle and its internal data processing process It is the same as the first embodiment and will not be repeated here.

Abstract

The invention discloses an image amplification method and an image amplification device. Based on a bilinear interpolation method, the calculation of the gray value of each pixel point to be inserted into the amplified target image is converted into add operation and second power shift operation of gray values of two adjacent pixel points in the to-be-inserted direction, and the gray values of two adjacent pixel points are added and shifted according to the calculation to obtain the gray value of each pixel point to be inserted. Because the gray values of pixel points to be inserted into the target image are calculated without complex floating point multiplication, the processing speed of image amplification is improved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image enlargement method and device. Background technique [0002] In the existing image processing process, it is often necessary to adopt an effective method to change the size of the original image, and ensure that the changed target image has better quality, and will not cause obvious image distortion to the enlarged target image . Among them, how to ensure that the enlarged target image has better quality and does not produce obvious image distortion is the key point of the image enlargement technology. After the original image is enlarged to obtain the target image, the gap between the new pixels corresponding to the original image pixels in the target image will become larger. At this time, it is necessary to construct New pixels are used to fill these gaps to ensure that the enlarged target image has better image quality without obvious image distortion. [0003] At ...
