SCREEN GENERATING APPARATUS, SCREEN GENERATING METHOD, AND IMAGE PROCESSING APPARATUS
First Claim
1. A method of generating a screen for an image processing apparatus, which reproduces a multi-gradation image in one pixel using a PWM technique for controlling a pulse width and reference position data, the method comprising:
- inputting image data with a first resolution; and
generating a screen with a second resolution with respect to the image data using two reference vectors based on the reference position data, the second resolution being enhanced from the first resolution using the reference position data.

Abstract
Disclosed is a method of generating a screen for an image processing apparatus, which reproduces a multi-gradation image in one pixel using a PWM technique for controlling a pulse width and reference position data. The method includes inputting image data with a first resolution, virtually increasing the first resolution to a second resolution using the reference position data, and generating a screen with the second resolution with respect to the image data using two reference vectors based on the reference position data.
