Abstract: The present invention provides an image display device capable of, by using a general-purpose image display driver configured to operate based on display data pieces each containing tones corresponding to plural bits, quickly performing bit extension processing to perform tone display corresponding to the display data pieces without providing any special circuit configured to perform the bit extension. A controller (9) is configured to combine the display data pieces output through display data output terminals (P0 to P2) with fixed values output through operation code output terminals (C01 to C05, C07 to C12, and C14 to C17) which are not commonly connected to the display data output terminals, store in a display memory (12) the combined data pieces as tone codes each containing predetermined two or more bits, and set a tone conversion table such that the stored tone codes correspond to tone output values.

Abstract: A sanitary cleaning apparatus includes a cleaning water discharger and an additional apparatus (such as a drier) having a sanitary function, and a set of switches operatively connected to the cleaning water discharger and the additional apparatus, respectively. When a switch is manually operated, a first setting control sets the energization amount of the cleaning water discharger and/or the additional apparatus to a first set value. When a second setting control is manually operated, the energization amount is changed to a second set value set by the second setting control. When a human body detector is turned off, the energization amount is returned from the second value to the first value.
