Abstract: Disclosed are an LCD power source control method and a control circuit thereof and an image forming apparatus having the control circuit. When a logic circuit voltage detecting circuit (voltage detecting means) detects a voltage drop of a power source of a power voltage +5V (logic circuit power source), a residual charge of a liquid crystal display (LCD) is forcibly discharged by an LCD power source control circuit (display voltage control means), whereby an LCD drive voltage can be caused to attenuate faster than the fall of the power source of the power voltage +5V (logic circuit power source) of a logic power source of the LCD, that is, a power source unit, therefore the liquid crystal display (LCD) will not be damaged.

Abstract: In order to obtain a vertically enlarged image with no indentation, reset timing of a data skipping counter is changed between odd and even lines by one horizontal scanning line by an output of a selector. Thus, data skipping timing for a signal by an AND gate is displaced between odd and even frames by one horizontal scanning line, whereby positions of inserted lines overlappingly read from a display memory in correspondence to the skipping are also displaced between odd and even frames by one horizontal scanning line. Further, color data of the inserted lines are converted to those having low chromaticity levels by +1 processing by an adder, to be supplied to a display unit. Thus, indentation of an oblique thin line, for example, is blurred so that a smooth vertically enlarged image is obtained.
