  • Patent number: 7052104
    Abstract: A carriage motor is driven with a predetermined duty value and it is determined whether a carriage is moved. If it is determined that the carriage is moved, a lower duty value is set. If it is determined that the carriage is not moved, a higher duty value is set, in order to obtain the duty values at the time when the carriage is and is not moved. The duty values when the carriage is moved and is not moved, are stored, as alternative characteristic values, in an EEPROM in association with positional information of duty value detection position. Therefore, quality control may be properly performed by checking the stored duty values.

  • Patent number: 6714211
    Abstract: A monitor calibration method for determining the black point of a monitor display, wherein a solid black display area and a gray display area are displayed on a monitor screen in the form of stripes, for example, so that each display area is sandwiched by the other type of display area. Then, while the brightness of the gray display area is gradually changed, the user signals OK using a mouse device at the point in time that the viewer determines a difference between the two display areas. The input value of the gray display area at that time is fixed and saved as the black point. By arranging the display areas in alternating stripes, even a subtle difference in the two display areas is visually striking. Hence, a very accurate black point can be determined.

  • Patent number: 6122002
    Abstract: The standard brightness region is displayed with input values of zero. The comparison brightness region is displayed with an input value which is variable in the range of 0 to 255. The standard brightness and comparison brightness regions are displayed next to each other in the display. The input value is changed from zero. A first black point is determined as an input value which causes the comparison brightness region to first appear distinguishable from the black regions of the standard brightness regions. Then, the input value is changed from 255. A second black point is determined as an input value which causes the comparison brightness region to first appear indistinguishable from the black regions of the standard brightness regions. Then, a black point is calculated as an average of the first and second black points.
