Abstract (en)

[origin: EP0519743A2] An image information control apparatus includes: a. first means for generating and outputting an image information transfer timing signal for controlling a transfer timing of image information; b. second means for thinning the image information transfer timing signal transferred from the first means in accordance with an environmental temperature and outputting a thinned image information transfer timing signal; c. third means for controlling a voltage waveform upon reception of the image information transfer timing signal; and d. fourth means for controlling the third means so that the voltage waveform is kept constant during a period of at least two continuous image information transfer timing signals output from the second means. <IMAGE>
