  • Publication number: 20110200313
    Abstract: A camera apparatus and a camera system of the present invention are configured so that a lens unit is attachable/detachable. The lens unit contains at least a lens and an iris, and contains a memory storing setting information required for operating the lens and the iris. When a camera microcomputer checks detection information stored in a memory in a sub-microcomputer at a time of start-up of the camera apparatus, and first detection information is stored in the memory, the setting information is acquired from the lens unit. When second detection information is stored in the memory, the setting information is acquired from another memory in the camera apparatus. Due to this configuration, the time for shifting the switch-on to a photographable state is shortened, and the ease of convenience can be enhanced.

  • Publication number: 20090021777
    Abstract: A print system capable of accepting a print request over a network, having a simple configuration, and easy to use. The print system includes a digital camera (10) serving as an information device for storing image data, order reception servers (104) adapted for accepting a print order from a digital camera and connected to the digital camera over a network (400), and a registration center server (300) for managing the information in an order reception server (104) which can accept a print order from the digital camera (10). When the digital camera (10) sets up communication with the order reception server (104), the digital camera (10) inquires the URL of the order reception server (104) of the registration center server (300) over the network (400). The registration center server (300) sends the URL of the order reception server (104) which can accept a print order from the digital camera (10) to the digital camera.

  • Patent number: 6040860
    Abstract: A gradation compensation circuit for gradation compensating the luminance level of the image signal is disclosed. An image evaluator evaluates the amount of backlighting and normal lighting in the overall image, and defines the degree of gradation compensation to be applied by the gradation compensation circuit according to the result of image evaluation. An AGC circuit maintains the overall luminance of the image constant. When the AGC control signal applied to the AGC circuit is high, the degree of compensation is suppressed, but when the AGC control signal is low, the degree of compensation is used without being suppressed.

  • Patent number: 5517333
    Abstract: An average luminance Y is added to a correction coefficient by an adder. The correction coefficient characterizing the gradation correction characteristic of input picture signals of a picture is determined easily according to feature quantities extracted from input picture signals. A first gradation correction characteristic and a second gradation correction characteristic are added to a weight according to the correction coefficient and a correction gain of the gradation correction characteristic is determined. Thus, gradation can be corrected for all kinds of pictures including front-lit and back-lit objects. Further, by using the average luminance Ya, gradation is corrected in pixel units so as to keep contrast and to send an output signal with good gradation. A quantizer in the correction coefficient determination circuit quantizes the level distribution of the luminance signal and the correction coefficient determination circuit provides the correction coefficient according to the quantized value.
