2 is a pulse waveform diagram at window setting.

3 is a control flowchart illustrating a window setting process and a moving process according to an embodiment of the present invention.

Hereinafter, an operation according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following description and drawings, numerous specific details are set forth, such as window size setting keys, key naming such as window navigation keys, and specific processing flows, to provide a more general understanding of the invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a block diagram for setting a window size according to an embodiment of the present invention, FIG. 2 is a pulse waveform diagram when setting a window, and FIG. 3 is a window setting process and movement according to an embodiment of the present invention. Each control flow diagram for explaining the process is shown. First, referring to FIG. 1, the key input unit 100 includes a plurality of function keys (for example, a window size setting key and a window moving key) according to an embodiment of the present invention, and generates key data according to a key press to generate a microcomputer. Output to (110). For example, the window moving key is designed to move the window set in the corresponding direction by one step when using the VR having eight contacts in the left, right, up, down and oblique directions. The key input unit 100 includes a start point setting key and an end point setting key for inputting horizontal and vertical sizes of the window. At this time, in order to set the start and end points of the horizontal and vertical sizes of the window size, one horizontal scanning period (1H) of the display screen is processed in N equal parts and one vertical scanning period (1V) in M equal parts. That is, as the display screen is subdivided, fine adjustment of window movement is possible. On the other hand, the microcomputer 110 has a memory consisting of a ROM for storing a control program according to an embodiment of the present invention and a RAM for temporarily storing data generated during a set control operation, and setting and moving a window according to the control program. Controls the overall operation of the special effect processing operation using the set window. For example, when the start point and the end point for the horizontal and vertical sizes of the window to be set are respectively input from the key input unit 100, the microcomputer 110 corresponds to the corresponding horizontal window size (HORIZONTAL WINDOW SIZE: HWS) data. And the vertical window size (VWS) data are output to the pulse generator 120. The microcomputer 110 controls the DSE processing unit 150 to enable special effect processing on the set window size. The pulse generator 120 outputs the HWS / VWS data input from the microcomputer 110 to the path switching unit 140 in synchronization with the horizontal synchronization signal H-sync and the vertical synchronization signal V-sync. The path switching unit 140 according to the logic level of the horizontal window size pulse (hereinafter referred to as HWSP) and the vertical window size pulse (VERTICAL WINDOW SIZE PULSE: hereinafter referred to as VWSP) input from the pulse generator 120. The Y signal and the C signal processed by the Y / C processor 130 are selectively output to the DSE processing unit 150. For example, when the logic level of the HWSP and VWSP is at the "high" level, the path switching unit 140 causes the signal output from the Y / C processor 130 to be output to the mixing unit 160, and is at the "low" level. Is output to the DSE processing unit 150 so that the Y / C signal in the set window section can be processed with special effects. Meanwhile, the mixing unit 160 mixes and outputs the Y / C signals input from the path switching unit 140 and the DSE processing unit 150 in synchronization with the horizontal synchronization signal H-sync and the vertical synchronization signal V-sync.

Hereinafter, a window setting process and a moving process will be described with reference to FIGS. 1 to 3.

First, when the window size setting key is input in step 170, the microcomputer 110 switches to the window size setting mode and checks whether there is a horizontal window size input in step 172. The inspection method can be known by checking whether there is a start point and an endpoint input for a horizontal window size. If the start / end points for the horizontal window size are C / D points shown in FIG. 2, the horizontal window size becomes A on the display screen. On the other hand, if the endpoint for the horizontal window size is finally input in step 172, the microcomputer 110 proceeds to step 174 to check whether there is an input for the vertical window size in the same manner as described above. If the start / end points for the vertical window size are the E / F points shown in FIG. 2, the vertical window size becomes B on the display screen. As described above, when the key input for the horizontal and vertical window sizes is completed, the microcomputer 110 proceeds to step 176 and outputs the HWS and VWS data for the horizontal and vertical window sizes to the pulse generator 120. As a result, the HWSP and VWSP output in synchronization with the horizontal synchronous signal H-sync and the vertical synchronous signal V-sync become the pulse waveforms shown in FIG. The path switching unit 140 directly outputs the Y / C signal input from the Y / C processor 130 to the mixing unit 160 when the HWSP and VWSP are at the "high" level, and the HWSP and VWSP are at the "low" level. When outputting to the DSE processing unit 150, it is possible to set the window having the A, B horizontal / vertical size on the display screen of FIG. Thereafter, the microcomputer 110 checks whether there is a window movement key input in step 178, and if there is an input, the microcomputer 110 moves the window to the movement command position in step 180. In response to the key input for processing the special effects, the screen within the window section set in step 182 is processed in response to the special effects.

Therefore, the present invention can set the window section desired by the user in the display screen to process the special effects, and can freely move the window section set according to the situation.

As described above, the present invention has an advantage of allowing the user to normally view the remaining displayed screen other than the set window section by setting only a portion desired by the user as the window section in the display screen.
