Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] In the embodiment of the present invention, after horizontal interpolation is performed row by row for all rows of the image, vertical interpolation is performed column by column for the image that has completed row pixel interpolation, and pixel interpolation and rotation are performed simultaneously, speeding up the process of image processing. The speed of pixel interpolation reduces the cost of pixel interpolation applications.

[0028] figure 1 The implementation flow of the image pixel interpolation method provided by the embodiment of the present invention is shown.

Abstract

The invention is suitable for the technology of image processing and provides an image pixel interpolation method and an image pixel interpolation system thereof. The method comprises the following steps of: acquiring rows to be interpolated in an image according to the image; carrying out horizontal 1 / 2 pixel interpolation on the rows to be interpolated in the image; carrying out horizontal 1 / 4 pixel interpolation on the rows which are subjected to the horizontal 1 / 2 pixel interpolation; carrying out vertical 1 / 2 pixel interpolation and vertical 1 / 4 pixel interpolation on columns which are subjected to the horizontal 1 / 4 pixel interpolation; and carrying out diagonal 1 / 4 pixel interpolation on columns which are subjected to vertical 1 / 2 pixel interpolation and columns which are subjectedto vertical 1 / 4 pixel interpolation. In the method, the pixel interpolation is carried out by rows and then by columns, so the speed of the image interpolation is effectively improved, the buffering area required by the image interpolation is saved and the cost is reduced. Simultaneously, the rotation of 90 degrees or 180 degrees or 270 degrees of the image is synchronously carried out when the method supports the image pixel interpolation.

Description

technical field [0001] The invention belongs to the field of image processing, in particular to a pixel interpolation method and system. Background technique [0002] At present, mobile multimedia processors are widely used in various portable electronic products, and the market has higher and higher requirements for their performance, which puts forward higher requirements for the video processing capabilities of mobile multimedia processors. Among them, a number of technical standard specifications have been formulated for the compression technology used to store and transmit large amounts of data. [0003] According to image compression standards, enlarging an image requires an interpolation operation on image pixels. When performing 1 / 4 interpolation operation in the prior art, the commonly used method is to perform 1 / 2 pixel interpolation on the image first, and then perform 1 / 4 pixel interpolation on the image according to 1 / 2 pixel and integer pixel interpolation. ...
