Semi-wide view display method and device using the same

A semi-wide view display, comprising:

• a mode selector for setting a display mode according to a user-selected aspect ratio of a television screen;
• a blanking pulse generator for receiving vertical blanking pulses and horizontal blanking pulses from a television image signal, and generating a blanking pulse having a width which is determined according to the display mode set by said mode selector and the received vertical blanking pulses and horizontal blanking pulses;
• a television/blanking signal generator for generating a television signal which is displayed on the television screen and a blanking signal which is not displayed on the television screen by inputting said generated blanking pulse;
• a CRT for displaying an image according to the television signal and blanking signal processed by said television/blanking signal generator;
• a mode output means for outputting a predetermined signal according to the display mode set by said mode selector;
• and
• a vertical/horizontal deflection controlling means for controlling vertical and horizontal size of the image displayed onto said CRT according to an output of said mode output means.

A semi-wide view display method comprising the steps of:

• (a) setting a display mode according to a user-selected aspect ratio of a television screen;
• (b) receiving vertical blanking pulses and horizontal blanking pulses from a television image signal, and generating a blanking pulse having a width which is controlled according to the display mode setting and the received vertical blanking pulses and horizontal blanking pulses;
• (c) generating a television signal which is displayed on the television screen and a blanking signal which is not displayed on the television screen by inputting said generated blanking pulse;
• and
• (d) displaying the television signal and the blanking signal processed in the step (c), wherein said blanking pulse is generated by:
• (b1) counting a first predetermined number of said horizontal blanking pulses after a falling edge of a first of said vertical blanking pulses;
• (b2) counting a second predetermined number of said horizontal blanking pulses after a falling edge of a second of said vertical blanking pulses, said second vertical blanking pulse following said first vertical blanking pulse;
• and
• (b3) establishing the width of said blanking pulse according to said steps (b1) and (b2) above.
