PROBLEM TO BE SOLVED: To upgrade discernment of display despite color anomaly, which cannot recognize red, at the time of performing display suitable for a dark place.SOLUTION: Included are lightness changing means that changes lightness of each of R, G, and B components of a display item displayed in a display section, sensing means that senses a manipulated state of a display item in the display section, and control means that controls the lightness changing means so that red display is achieved by decreasing the unchanged lightness of each of the G and B components of a portion concerning the display item in the display section down to first lightness, and thus allows the portion concerning the display item to be displayed in red, and controls the lightness changing means so as to raise the lightness of at least one of the G and B components to second lightness, which is higher than the first lightness, according to the manipulated state sensed by the sensing means during a first period during which the red display is achieved.SELECTED DRAWING: Figure 3 |
