Embodiment Construction

[0036] According to an embodiment of the present invention is figure 2 The image processing device 200 shown includes a first memory 21 , a capture module 22 , a buffer 23 , a processing module 24 and a second memory 25 . In practical applications, the image processing device 200 can be integrated in various image processing systems or image playback devices, or exist independently. In practice, the first memory 21 and the second memory 25 may be different areas of the same memory, or may exist in two different memories. The following description will mainly take the case where the image processing device 200 receives 30 original images with a size of 3840 columns of pixels*2160 columns of pixels per second as an example, but it is not limited thereto.

[0037] The original image received by the image processing device 200 is firstly stored in the first memory 21; the first memory 21 can at least accommodate image data of 3840 pixels*2160 pixels, that is, the image data of a ...

Abstract

The invention provides an image processing apparatus. The image processing apparatus comprises a first memory, a second memory, a buffer, a capturing module and a processing module. The first memory is used to store an original image possessing a first width. The buffer possesses a second width which is less than the first width. The capturing module captures one sub-image in the original image from the first memory and stores the sub-image into the buffer. The processing module carries out an image processing program aiming at the sub-image stored in the buffer so as to generate a processed sub-image. The processed sub-image is stored into the second memory.

Description

technical field [0001] The present invention relates to image processing techniques, and in particular to techniques for managing / using memory in image processing systems. Background technique [0002] In recent years, with the vigorous development of various electronic products, multimedia systems such as home theaters have become increasingly popular. In most multimedia systems, the most important hardware device is an image display device. In order to satisfy viewers' demands for realistic images, one of the development trends of image display devices is to continuously increase the size and resolution of images. Generally speaking, a large-size, high-resolution image display device must have a relatively high computing speed and memory capacity. [0003] FIG. 1(A) is an example block diagram of an image display device. The function of the scaler (scaler) 12 is to adjust the size of the input picture, so that the size / ratio of the scaled picture matches the specificati...
