    • The present invention provides a method and apparatus for color adjustment of a display screen which can provide an interactive user interface which allows a user to perform color adjustment efficiently and effectively. The color adjustment of the display screen in a color display device, such as LCD, CRT or the like, is performed by displaying a color image without any color adjustment at a certain portion of the display screen, displaying a color image with a color adjustment at another portion of the display screen, and referring to the color image without any color adjustment. And to implement this method for color adjustment, the apparatus is configured so that the color images which have passed the color adjustment block and have their colors adjusted, and the color images which have not passed the color adjustment block and are not subject to the color adjustment can be both displayed on the same display screen.

    • An apparatus for detecting overlapped paper sheet feed in a paper sheet feed path. The apparatus includes a photosensor and a load resistor located in the paper sheet feed path for detecting a voltage representing a light transmittivity of paper sheet(s) fed through the paper sheet feed path. The apparatus also includes a resistor control for changing the resistance value of the load resistor between a first resistance which generates a predetermined detected voltage at the feed of a single paper sheet of the highest light transmittivity and a second resistance generating the predetermined detected voltage at a feed of a single paper sheet of the lowest light transmittivity and for comparing a detected voltage of a first paper sheet with the predetermined detected voltage to generate a first signal indicating that the detected voltage is equal to the predetermined detected voltage and a second signal indicating that the detected voltage is not equal to the predetermined detected voltage and for fixing the resistance value of the load resistor in response to the first signal and generating an error signal representing the overlapped paper sheet feed in response to the second signal. The apparatus also includes means for comparing a detected voltage of a second paper sheet with a first threshold voltage which is established separately from the predetermined detected voltage to discriminate a single paper sheet feed and an overlapped paper sheet feed in order to generate an error signal when the detected voltage of the second paper sheet is a voltage indicating an overlapped paper sheet feed.

    • An image display system includes a host side for executing an application and transmitting image data having a P dot width in a block unit with the number of m dots as the width of the block. A panel side is connected through a digital I/F line to the host side, which converts the image data having a P dot width by using magnification to produce data having an R dot width and then displays the image data. The panel side executes scaling by using a block having an integral value obtained by a R×m/P set as a dot width and a block having a dot width of an added integral value obtained by adding 1 to the integral value, and converts by magnification the image data received from the host side in block unit based on the executed scaling and displays the image data on a panel.
