Embodiment Construction

[0016] figure 1 It is a configuration diagram of an apparatus for serially scaling 16-bit video data or graphics data according to the present invention. figure 1 Among them, the serial calibration device includes a source data input unit 11, a serial output unit 12, a calibration device 13, and a scaled display data output unit 14.

[0017] The source data is input to the source data input unit 11. The source data can be input to the source data input unit 11 from the system memory. Generally, the system memory is called random access memory (RAM), which is a work space memory in a personal computer (PC). When the user uses the mouse or cursor to enlarge or reduce the PC window, RAM stores the display data representing the original size of the window, that is, the display data the user is encoding, and RAM also stores the scaling ratio corresponding to the enlargement or reduction of the window, namely The calibration ratio set by the user. Furthermore, source data can be inpu...

Abstract

The present invention provides a scaling device and method for zooming in or out of a video or graphics window. The scaling device includes: a source data input unit for inputting source data; a serial output unit for serially outputting display data included in the source data; Scaling the display data serially output; a calibrated display data output unit that outputs the calibrated display data. The scaling speed of the scaling device is improved by processing the application for zooming in or zooming out the video or graphics window with hardware. Also, the size of the internal memory of the scaler is reduced by serial scaling. In addition, desktop calibration can be performed in a light and small mobile environment.

Description

Technical field [0001] This application claims priority from Korean Patent Application No. 2002-42761 filed on July 20, 2002, which is hereby incorporated by reference in its entirety. [0002] The present invention relates to a device and method for processing an application for enlarging or reducing a video or image window in the form of hardware, in particular to a scaling device and method for enlarging or reducing a video or image window in a mobile environment . Background technique [0003] Traditionally, when scaling to enlarge or reduce a window, the central processing unit (CPU) controls all the scaling processing by including the scaling in the software. As a result, the performance of the CPU is reduced. In particular, the conventional scaling device using the parallel processing type scaler cannot handle the current mobile environment due to memory size and power consumption. Summary of the invention [0004] In order to solve the above-mentioned problems, an object...
