Problems solved by technology

It can be seen that it is impossible to effectively process image data with both
[0005] Therefore, if only a single sampling rate and quantization table is used to process a single image data, the best image quality cannot be obtained, and if the image data has a high contrast between the front and rear images, a sampling mode with less loss and a High quantization table to deal with, it is quite uneconomical on a network with limited bandwidth

Embodiment Construction

[0072] Please refer to FIG. 1 , which shows a block diagram of an image transmission system for dynamically adjusting and processing data patterns according to a preferred embodiment of the present invention. The image transmission system 100 includes at least one source device 101, at least one destination device 102, a compression system 200a and a decompression system 200b. Wherein, the source device 101 is, for example, a computing component that can provide image data or an image camera. The target device 102 is, for example, a display. The present invention provides a compression system 200a and a decompression system 200b to dynamically adjust and process data patterns between the source device 101 and the destination device 102 . The compression system 200a and decompression system 200b will be described in detail below.

[0073] Generally speaking, the compression system 200a and the decompression system 200b will control the type of data transmission mode between t...

Abstract

The present image compression system of the present invention adopts a variety of compression criteria by dynamically adjusting the sampling modes and quantization formats based on a plurality of thresholds. The present image compression system uses an analyzer compares two image data stored in two buffers to determine one of the sampling modes and quantization formats based on the pixel value change between two consecutive image data. Once the pixel value change moves from one threshold to another threshold, the sampling modes and the quantization formats may be changed.

Description

technical field [0001] The present invention relates to an image transmission system, and in particular to a compression system capable of dynamically adjusting a sampling mode and a quantization table. Background technique [0002] In recent years, various information such as text data, image data, and sound data have been digitized due to the development of browsers and computer broadband networks. These digitized data can be transmitted to multiple users via the Internet. [0003] Traditionally, when digitized data is transmitted over a network, various digitized data are processed with the same sampling mode and quantization table. When the digitized data is a character data, and the character data has gentle pixel value changes between consecutive frames, the above-mentioned digitized data processing method is acceptable. [0004] However, both sharp pixel value changes and gentle pixel value changes exist on continuous image data. Therefore, it is not enough to proc...
