Location information representing the location of a defective pixel in an image pickup device and pixel defect level information representing the pixel defect level of the defective pixel are stored beforehand in a memory. The defect level of the defective pixel is determined after shipment of the image pickup device, and the pixel defect information is updated based on the defect determination result. If a new defective pixel is detected at a location different from the location of the defective pixel with the pixel defect information stored in the memory, the pixel defect information of that defective pixel is added. If a defective pixel is detected at the same location as the defective pixel with the pixel defect information stored in the memory, and if the defect level of the detected defective pixel is worse than the original defect level, the defect level of the defective pixel is updated.

A radio receiver includes a channel estimation unit, phase difference vector generation unit, correction coefficient setting unit, and noise estimation unit. The channel estimation unit obtains a channel estimated value from a received signal at a predetermined period by using a known pilot signal. The phase difference vector generation unit obtains a phase difference vector between the preceding channel estimated value and the current channel estimated value. The correction coefficient setting unit sets a correction coefficient corresponding to the phase difference vector. The noise estimation unit obtains a corrected noise estimated value by correcting a noise estimated value on the basis of the received signal and the correction coefficient. A noise estimated value correction method is also disclosed.

A highly reliable light-emitting element that shows a novel degradation curve when driven is provided. The degradation curve of a light-emitting element with a long lifetime is represented by a function composed of two exponential functions, which is a linear combination of an exponential function expressing an initial degradation component and an exponential function expressing a long-term degradation component. The initial degradation component is represented by a stretched exponential function, and the long-term degradation component is represented by a single exponential function. When the proportion of the initial degradation component of the degradation curve represented by the function composed of two exponential functions is less than or equal to 0.25, preferably less than or equal to 0.20, and further preferably less than or equal to 0.15; a highly reliable light-emitting element is obtained.

An optical pickup for recording a hologram by using an angle multiplexing method. An optical beam is separated into two beams, a signal beam and a reference beam having different convergence / divergence degrees, by using an optical component such as a diffraction lens. The signal and reference beams are made incident upon the same objective, and the optical component or the objective lens is moved in a direction perpendicular to an optical axis, to thereby realize angle multiplex recording. If an optical information recording medium is inclined, the optical component or the objective lens is moved along the direction along which the optical information recording medium moved to change an angle of the reference beam incident upon the optical information recording medium and compensate for degradation of a reproduction signal.

A metal oxide layer is disposed on the lower potential side when an electric field in a predetermined direction is applied to the piezoelectric body which is deformed by an applied electric field, and compensates for the oxygen vacancies which are generated in the piezoelectric body by applying the electric field. A second metal oxide layer is disposed on the higher potential side of the electric field applied to the piezoelectric body, and by applying an electric field in the direction reverse to the electric field, compensates for the oxygen vacancies which are accumulated in the piezoelectric body, thus degradation of the piezoelectric characteristic of a piezoelectric element can be repaired.

A highly reliable light-emitting element that shows a novel degradation curve when driven is provided. The degradation curve of a light-emitting element with a long lifetime is represented by a function composed of two exponential functions, which is a linear combination of an exponential function expressing an initial degradation component and an exponential function expressing a long-term degradation component. The initial degradation component is represented by a stretched exponential function, and the long-term degradation component is represented by a single exponential function. The light-emitting element is highly reliable when formed to show a degradation curve represented by the function composed of two exponential functions. In other words, the function composed of two exponential functions in one embodiment of the present invention is capable of accurately fitting the degradation curve of the highly reliable light-emitting element.
