Embodiment Construction

[0028] The present invention provides an image processing device and method for processing an interlaced scanning image, which determines the edge pixels associated with an edge of a moving object, and calculates the gray scale value of the edge pixels by an average method. Thereby, jagged edges or other picture defects caused by image conversion can be reduced, thereby improving image quality. In addition, by judging whether an individual pixel is associated with a moving object, a stationary object or a micro object, and adopting different processing methods, the software and hardware resources of the image processing device can be well utilized and the processing speed can be accelerated. Specific embodiments of the present invention will be described in detail below, so as to fully illustrate the features, spirit, advantages and simplicity of implementation of the present invention.

Abstract

The invention provides an image processing device for processing an interleaved image comprising a judging module, a determination module and a processing module. The judging module judges if pixel in one image of multiple interleaved images is correlated with a mobile object; if it is correlated, then the determination module determines a pixel being one of two adjacent pixels to judged pixel as an edge pixel correlated to one edge of mobile object. The first processing module calculates the gray level of the edge pixel determined by determination module by an average method.

Description

technical field [0001] The present invention relates to an image processing apparatus, and more particularly to an image processing apparatus for processing an interlaced video. Background technique [0002] In today's ATSC TV system, or some DVD content, in order to save bandwidth, interlaced images are often used. To convert an interlaced image into a progressive video, a deinterlace method is generally used, such as field insertion method, duplicate field method, and edge-based line averaging (ELA) method. , Edge-based Line Average) method, 3D-ELA method and average method (average way)...etc. [0003] However, if the image contains fast-moving objects, the above-mentioned de-interlacing method is used to process the image, and picture defects such as jagged edges or ghost images often appear in the picture of the picture, thereby degrading the quality of the picture. [0004] Therefore, the main scope of the present invention is to provide an image processing device an...
