Embodiment Construction

[0014] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The "comprising" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

[0015] Please refer to figure 1 , figure 1 A simplifi...

Abstract

An image processing apparatus and method for scaling an input image are disclosed. The image processing apparatus includes a buffer module, a scaling unit, and a determining unit. The buffer module includes at least a line buffer for buffering pixel data of the input image. The scaling unit is coupled to the buffer module and includes a plurality of filters having different filter tap numbers, wherein the scaling unit utilizes a target filter having a specific filter tap number selected from the plurality of filters to scale the input image according to the pixel data retrieved from the line buffer. The determining unit is coupled to the scaling unit and utilized for receiving an image processing requirement and setting a pixel precision of the input image and selecting the target filter having the specific filter tap number from the filters in the scaling unit according to the image processing requirement.

Description

technical field [0001] The present invention relates to an image processing device and method, and more particularly to an image processing device and method for scaling an input image according to different image processing requirements. Background technique [0002] Display devices such as televisions, LCD displays, plasma displays, and projectors can be used to display still images or moving video. Different video formats usually have different resolutions: for example, the Video Graphics Array (Video Graphics Array, VGA) format has a resolution of 640*480, while the Advanced Extended Graphics Array (Super Extended Graphics Array, SXGA) format has a resolution of 1280*1024 resolution. If the resolution of the display device is different from that of the input image, the input image must first be scaled to display correctly. [0003] In traditional techniques, there are two common image processing methods to scale the input image. The first image processing method uses ...
