Image processing device and method and liquid crystal display

一种图像处理装置、方法及液晶显示器

Abstract

本发明提供一种图像处理装置,包括:缓存单元、缩小处理单元、同步动态随机存储器SDRAM、过驱动处理单元、比较单元、恢复处理单元以及输出控制单元。本发明还提供一种图像处理方法及液晶显示器。本发明所提供的图像处理装置、方法及液晶显示器并不对输入的高分辨率图像直接进行过驱动处理,而是一方面将输入的高分辨率图像在缓存单元缓存,另一方面将输入的高分辨率图像进行缩小处理,使得实际进行过驱动处理时,图像数据量已被缩减,所消耗的SDRAM空间也相应减少,对于高分辨率图像输入,不必再增加SDRAM的数量,易于成本控制。在输出时对于静态图像则直接输出,对于动态图像则输出经过驱动处理并且恢复成原有分辨率的图像,以维持图像的品质。
The invention provides an image processing device which comprises a cache unit, a reduction processing unit, an SDRAM (synchronous dynamic random access memory), an overdrive processing unit, a comparison unit, a recovery processing unit and an output control unit. The invention also provides an image processing method and a liquid crystal display. The image processing device and method and the liquid crystal display provided by the invention do not directly perform overdrive processing on an input high-definition image but cache the input high-definition image in the cache unit while performing reduction processing on the input high-definition image, so that the image data quantity is reduced when in practical overdrive processing, the consumed SDRAM space is correspondingly reduced, the number of the SDRAM is not necessarily increased for inputting high-definition images, and the cost is easy to control. During output, a static image is directly output; and for a dynamic image, the image subjected to overdrive processing and recovered to the original definition is output so as to maintain the image quality.
