Abstract: A coding device has a difference calculating unit that calculates a quantized value, which is represented by lower-order bits than a quantization bit rate allocated to a processing unit in image data in a selected coding pattern, from a quantized value obtained by quantizing a pixel value in the processing unit with a maximum quantization bit rate in the coding device, as a difference.

Abstract: A touch panel-equipped display device includes at least: a display control unit to supply a scan signal and a data signal to a display control element; and a touch position detection control unit to supply a drive signal to a drive electrode, and to detect a position detection signal from a detection electrode to detect a touch position.

Abstract: It is an object of the present invention to provide an output circuit capable of reducing a consumption current while an output current is suppressed in a case where limitation is placed on an output voltage so as not to fall to a predetermined voltage or less in an output circuit the emitter of which is grounded, the base of which serves as an input node for a control current and the collector of which serves as an output node. Provided are a base current supply section for supplying a base current to the output transistor according to an input signal from the outside, and a base current control section for detecting an inter-terminal voltage between the collector and emitter of the output transistor to control a base current supplied from the base current supply section so as not to cause the inter-terminal voltage to fall to a value lower than a predetermined voltage.
