Abstract: An electronic apparatus includes an error detection times acquiring module and a waiting module. The error detection times acquiring module acquires the number of reading error detection times of a program according to a power-ON instruction instructing a power-ON operation, the number of error detection times being stored in a storage module. The waiting module waits for a reception of data capable of recognizing a communication counterpart device when the number of error detection times is more than a predetermined value by comparing the acquired number of error detection times with the predetermined value.

Abstract: A system has a corrected unit, and a correction unit that performs binary search of a correction value with which an output of the corrected unit gets close to a reference value and feeds back the correction value to the corrected unit.

Abstract: A picture is scrolled on a display 5 to be measured, and the scrolling moving picture is pursuit-captured by a color camera 3 so as to obtain a pursuit-captured moving picture image. A moving picture response curve using received light intensity data obtained based upon the pursuit-captured moving picture image is converted into a color moving picture response curve using emission intensity of display elements of the display 5 to be measured.
