Abstract: PROBLEM TO BE SOLVED: To provide a display device which enables a user to easily adjust color tone. SOLUTION: An information processor 100 which displays an image is provided with a display part 130 which displays an image including an information image for presenting information to the user, a display part cover which covers the edge part of an area where the display part 130 displays the image, a photodetection part 150 which is fitted at the same position of the display part cover and photodetects the image that the display part 130 displays both when the information is presented to the user and when the user adjusts the color tone of the information processor 100, and an adjustment part 340 which adjusts the color tone of the image that the display part 130 displays according to the color tone of the image that the photodetection part 150 photodetects.

Abstract: PROBLEM TO BE SOLVED: To reduce the size of an IC chip and increase the degree of freedom of a position of the IC chip on a substrate. SOLUTION: A wireless unit 19 for inputting and outputting data by wireless communication is formed in the IC chip together with a logic part 12. As a result, pads for a power source and ground only are left on the IC chip 16, and an I/O pad becomes unnecessary. ICs including the IC chip 16 to each other input and output data not by wires but by the wireless communication, so that the degree of freedom of a position of each IC on the substrate is increased.

Abstract: PROBLEM TO BE SOLVED: To output the same integration result for the same bit pattern even if the variation of an integrating period, a semiconductor process and power source voltage, etc., exists. SOLUTION: This integrator is provided with a first integrator 1 having a first amplifier 1 and integrating reference voltage during an integrating period, a second integrator having a second amplifier 11 and integrating an input signal during the integrating period and a control means 7 outputting the signal adjusting the gain of the first amplifier 1 to the first amplifier 1 and adjusting the gain of the second amplifier 11 by using the signal adjusting this gain, so that the output of the first integrator may be changed according to the integrating period.

Abstract: PURPOSE: To provide a current output type D/A converter which can appropriately compensate the fluctuation of characteristics caused by each constant current circuit. CONSTITUTION: Concerning a D/A converter 11 with which an analog output current corresponding to digital input data is provided from the output side by electrifying the respective output currents of plural constant current circuits while switching them to the output side or the non-output side corresponding to the digital input data, during a period in which the output currents of all constant current circuits L1 -L255 are switched to the non-output side, the feedback control of output current values from the constant current circuits is performed based on the analog output current on the non-output side.
