摘要： According to the present invention, when a current system is switched to a spare system in a transmission system in an asynchronous transfer mode, empty cells transmitted in the current and spare systems are detected, and thereby a timing for switching the current system to the spare system is determined. When no phase difference is existent between the current and spare systems, an empty cell is detected in both the current and spare systems at the same time. Therefore, the current system is switched to the spare system, when an empty cell is detected in both the current and spare systems at the same time. When a shade difference is existent, if an empty cell is detected either in the current or spare systems, another empty cell is inserted in to the systems. Then, the data of the empty cell in a spare system is saved. After the empty cell in a current system passes, the current system is switched to the spare system. When a phase difference of at least one cell is existent, and if an empty cell comes earlier in current system, empty cell are kept inserted form when the empty cell is detected in the current system until an empty cell is detected in the spare system. After that, the current system is switched to the spare system. When an empty cell comes earlier in a spare system, the data of the cell in the spare system is saved from when the empty cell is detected until an empty cell is detected in the current system. After that, the current system is switched to the spare system.

摘要： Disclosed is a display device capable of compensating unevenness in brightness caused by physical restrictions of a display device or degradation in image quality caused by a partial reduction in contrast occurring in the local dimming technology using human visual characteristics. A liquid crystal panel (101) modulates illuminating light in accordance with the transmittance, and displays images on a screen. A backlight (102) emits the illuminating light to the liquid crystal panel (101) such that amounts of the illuminating light differ for each light emitting area of the screen. A backlight control unit (106) controls emission brightness of the backlight (102) for each light emitting area. A local gradation converting unit (104) performs gradation conversion on an image signal, and acquires a brightness value for each pixel after the conversion. A backlight driving unit (107) controls the transmittance for each pixel on the basis of the acquired brightness values after the conversion. The local gradation converting unit sets conversion characteristics for pixels to be processed in the image signal such that the brightness values of the pixels to be processed are low as the lightness of the periphery of the pixels to be processed is high, and performs gradation conversion using the set conversion characteristics.

摘要： An imaging apparatus for capturing a moving image performs backlight correction of an image and outputs a natural image. The imaging apparatus electronically captures an image of a subject. An optical system has a light amount adjustment function. An imaging unit reads an optical image of the subject that is formed by the optical system. An A/D converter subjects an output of the imaging unit to A/D conversion. A backlight correction unit converts the tones of an image read by the A/D converter using a conversion characteristic selected differently according to a spatial position and at least increases the luminance level of a dark region of the image. An instruction unit instructs to start backlight correction. A control unit operates the backlight correction unit based on an instruction signal output from the instruction unit, and decreases an exposure light amount of the optical system by a predetermined amount.
