Embodiment Construction

[0021] According to an embodiment of the present invention is figure 1 The image processing device 100 shown includes a processor 12 , a memory 14 and a player 16 . In practical applications, the image processing device 100 can be integrated in various image processing systems or image playback devices, or can exist independently. It should be noted that the player 16 is not a necessary component.

[0022] FIG. 2(A) is a schematic diagram of the internal storage space of the memory 14 . As shown in FIG. 2(A), the memory 14 includes a first storage area 14A and a second storage area 14B. In practice, the physical locations and virtual addresses of the first storage area 14A and the second storage area 14B are not necessarily continuous, but may be composed of multiple dispersed blocks. Furthermore, the type of the memory 14 is not limited, such as a dynamic random access memory or a static random access memory.

[0023] In this embodiment, the first storage area 14A and the...

Abstract

The invention provides an image processing device comprising a processor and a storer. The processor is used for producing a target picture according to a reference picture stored in a storage area, wherein the target picture has a first image data volume, and the reference picture has a second image data volume. The storer comprises the storage area which is used for storing the reference picture and the target picture. The processor makes the target picture selectively overwrite a part of the reference picture. The volume of the storage area is smaller than the sum of the first image data volume and the second image data volume and is larger than the second image data volume.

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 related technologies, more and more mobile electronic devices have begun to provide complex image display functions such as playing dynamic videos. However, image processing must consume a large amount of memory space. Due to cost and power consumption considerations, compared with stationary electronic devices (such as desktop computers), mobile electronic devices usually have smaller memory capacity and weaker processor performance. If the memory usage is not properly controlled, the mobile electronic device may crash due to insufficient memory or forcibly close certain application programs when playing dynamic videos, causing troubles to users. [0003] Take the motion compensation (motion compensation) decoding me...
