  • Patent number: 5764848
    Abstract: In the disclosed picture recording device, an image pick-up arrangement converts an optical image into electric picture information and stores the information. A recording arrangement reads out the electric picture information on the image pick-up arrangement and records the information. A power supply control controls the power supply to the recording arrangement and a memory holds the electric picture information formed on the image pick-up arrangement at the start of the supply of power by the power supply control to the recording arrangement. This allows image information immediately to be picked up when the camera is turned on during the power up of the various camera circuits and thus avoids the loss of image information during the rise time.

  • Patent number: 5418926
    Abstract: A method and system for providing a display on a device to which a detachable solid state memory devices, which includes a plurality of memory blocks, is attached. The method includes the steps of determining to which of a plurality of broadcasting system standards a detected size of each of the memory blocks in the solid state memory device corresponds, and providing a display on an apparatus to which the solid state memory device is attached, such as an electronic still camera, based on the detected size. In a preferred embodiment, the broadcasting standards are NTSC (National Television Systems Committee) and PAL (Phase Alternation Line). A user is warned when a detected size of each of the memory blocks is not a predetermined size, thus, not the correct broadcasting system standard for the apparatus. Each of the memory blocks stores data corresponding to one picture image.
