Embodiment Construction

[0041] In order to make the purpose 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.

[0042] Such as figure 1 Shown, in the flowchart of the antialiasing method in the image compression of the present invention, comprise following steps:

[0043] A. Receive two-way Bayer format two-dimensional image data;

[0044] B. Convert the received two-way Bayer format two-dimensional image data into RGB format image data respectively;

[0045] C, reducing the image data in RGB format by half in the width direction, and obtaining the RGB format image data whose width is reduced by half;

[0046] D. Convert half-reduced RGB format image data into Bayer format image data, and then output.

[0047] Further, Step B specificall...

Abstract

The invention discloses an anti-aliasing method in image compression. The method includes the following steps: A. receiving two ways of Bayer format two-dimension image data; B. Respectively converting the received two ways of Bayer format two-dimension image data into RGB format image data; C. reducing the RGB format image data by one half in the width direction to obtain RGB format image data with width reduced by one half; and D. converting the RGB format image data which are reduced by one half into Bayer format image data and outputing the Bayer format image data. An anti-aliasing device in image compression is further disclosed. The anti-aliasing method and the anti-aliasing device in image compression can weaken the aliasing phenomena at the boundary position of scenes and improve image three-dimension performance and observation comfortableness of users.

Description

technical field [0001] The present invention relates to the technical field of image processing, and more specifically, to an anti-aliasing method and device in image compression. Background technique [0002] In the existing stereoscopic image capturing device, before synthesizing the two-way Bayer format two-dimensional image signals into one three-dimensional image signal, it is necessary to compress the two two-way two-dimensional image signals respectively in the width direction, and then do the synthesis operate. However, if this method is used to directly compress the received two-way Bayer format two-dimensional image signals in the width direction, a very serious aliasing phenomenon will be seen on the image obtained after compression. Comfort has a big impact. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-aliasing phenomenon that can effectively prevent the aliasing phenomenon in image compr...
