    摘要: When a shutter button of a digital camera is pressed, a picture signal fetched from a CCD is converted to a digital signal and compressed and written into a nonvolatile memory means like a flash memory card as a picture file which can be identified uniquely. By turning on a reproduction switch, a picture file is read out from the nonvolatile memory means, the compressed data is expanded and converted to an analog signal, and the converted picture is displayed on a liquid crystal display. By pressing a display feed key, another picture file is read out and displayed. A user can produce a control file for controlling print processing, display processing, transmission processing and the like for the picture file by selecting a particular picture file using an operation key. The nonvolatile memory means can be removed. By mounting this memory means on a printer unit, display unit or picture transmission unit, the digital camera also can be used during print, display or transmission of the picture. If multi-screen print is carried out on the printer unit, a vertical direction of each picture is unified. Further, upon reprint operation for multiple order persons, sorting work after the print is facilitated by providing with an identification means for identifying each order person.

    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.

    摘要: The present invention provides a network relay apparatus capable of assuring the prevention of occurrence of order reversion of packets within flows and shifting a packet distribution destination according to load information. The network relay apparatus includes: a packet distribution processor for distributing input packets to thereby achieve load dispersion of packet processing; a statistical information collector for regularly collecting load conditions of respective packet processors; and a distribution information holder for retaining information for specifying the packet distribution destinations upon distribution of the packets. Information about the load conditions of the respective packet processors are compiled and distributed to the packet processor smallest in load. Timing provided to change the packet distribution destination is assumed to be given when a processing waiting queue does not include a packet corresponding to its flow.
