  • Publication number: 20110193974
    Abstract: An electronic camera has an image data memory for storing image data and a communication mode for transferring the stored image data to one or more different cameras. The camera includes a controller that, prior to image data transmission, receives remaining capacity data of the image data memory in a receiver side camera and displays an image number corresponding to the remaining capacity of the receiver side camera. When plural receiver side cameras are available, the controller, prior to image data transmission, receives the remaining capacity data of the image data memory in the plurality of receiver side cameras and displays a number of sendable images corresponding to the remaining capacity for each of the plurality of receiver side cameras.

  • Publication number: 20020054278
    Abstract: A timing data recording device that prevents imprinting of incorrect timing data on a recording medium, such as a film loaded in a camera. The timing data recording device operates by power supply voltage from a detachable battery. When the battery of the timing data recording device is changed, a flag is automatically set so that imprinting of timing data on the film is inhibited. While this flag is set, there is no recording of incorrect timing data on the film. Moreover, when the battery is changed, until a data correction mode has been performed in order to correct the date and time, the flag remains set such that imprinting is inhibited. Thus, a user of the camera does not forget to reset the date and time after a battery change. Furthermore, the data correction mode is set only in the case that the usual select switch is actuated continuously for a predetermined time.

  • Patent number: 6275212
    Abstract: When displaying operational settings and measurements on a pointer type display device, the starting position of the needles is automatically adjusted even when there are battery exchange and needle drive process errors. The display device may be used to display physical quantities using pointers which move above scale plates. Even though the displays may be changed by electric supply loading, battery exchange or a fall in electric supply voltage, the display can be automatically corrected. A memory stores the movement destination position of the pointers, and instructions are generated by a controller which calculates the movement destinations of the pointers after the electrical supply voltage is stabilized properly. The instructions which control operation of a driver for the pointers preferably use a combination of movement to predefined positions and incremental movement.

  • Patent number: 6016407
    Abstract: An electronic device has a plurality of prestored limit times that define a time period of non-use, after which the electronic device will enter an energy-saving state. A different one of the plurality of limit times can be selected for different operating modes of the electronic device. Thus, when the electronic device is switched between different modes, different limit times, which define the duration of the non-use period prior to entering the energy-saving state, will take effect. Additionally or alternatively, a different one of the plurality of limit times can be selected for different geographical conditions. Thus, when the electronic device is being used in a first geographical condition, for example, a place where batteries are readily available and inexpensive, the limit time is increased in order to improve the operability of the electronic device.

  • Patent number: 5815749
    Abstract: A camera capable of operating in a red-eye prevention mode. The camera has an electronic flash device which is activated by a drive circuit in synchronization with the exposure. The electronic flash device also serve as a pre-light-emission device capable of performing pre-light-emission for the purpose of preventing red-eye effect. When it is judged from the photographing condition that red-eye effect may occur, a controller activates the electronic flash device to effect a pre-light-emission for reducing the size of pupils of eyes of a person to be photographed, before the main flashing which is executed in synchronization with the exposure.

  • Patent number: 5765058
    Abstract: A camera having a multiple speed film driving mechanism that can accurately read film data on a film cartridge. The camera has a motor that drives a spool axis of the film cartridge, and a reading device that can read film data stored on a recording medium on the film cartridge. When the film cartridge is loaded into the camera, the reading device reads film data on the recording medium that is rotated together with the spool axis at a first speed. When film data reading is finished, the spool axis is rotated at a second speed to feed the film into the camera. A motor drive control circuit and CPU controls spool axis rotation at multiple speeds and directions.
