Benefits of technology

The technical effect that this technology can be used for compression-restoration of image data has been described by researchers at Los Alamos National Laboratory (LAN). This technique helps recover digital documents from corrupted ones without losing their quality.

Problems solved by technology

The technical problem addressed by this patented method relating to improving image quality when compressing digital images with small differences from other parts of them (such as testing pattern) involves finding ways to improve efficient use of these slight variations without affecting their overall effectiveness on restoring high-contrast original images for various applications like medical imagery analysis.

Embodiment Construction

[0029]Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. In this regard, embodiments of the present invention may be embodied in many different forms and should not be construed as being limited to embodiments set forth herein. Accordingly, embodiments are merely described below, by referring to the figures, to explain aspects of the present invention.

[0030]FIG. 2 illustrates a Liquid Crystal Display Dynamic Capacitance Compensation (LCD DCC) system, according to an embodiment of the present invention.

[0031]Referring to FIG. 2, the LCD DCC system may include an image compression system 21, a memory 22, an image restoring system 23, and a Lookup Table (LUT) module 24, for example. The LCD DCC system may selectively apply a voltage higher than a voltage typically required for driving pixels of a Thin Film Transistor (TFT)-LCD panel to the pixels in order to

Abstract

A method, medium, and system effectively compressing and/or restoring binary images. By compressing pixel values making up a 2×2 block in an input image, using representative values representing the pixel values and a pattern of the pixel values represented by the representative values, it is possible to effectively compress and/or restore binary images having little similarities between pixel values. In addition, by extracting compressed values and a pattern of pixel values making up a 2×2 block in an image, from compressed data of the 2×2 block, and restoring pixel values using the compressed values and the pattern, it is possible to effectively restore binary images.
