  • Patent number: 8408824
    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.

  • Patent number: 8085341
    Abstract: A digital camera has a battery that supplies electric power, a battery level detector, a time detector, a remaining voltage calculator, and a boot controller. When the digital camera is turned off, the battery level detector detects a remaining voltage level of the battery. When the digital camera is turned on, the time detector detects an elapsed time from the last electric power OFF operation to the current electric power ON operation, namely, a time period in which the camera is in the OFF state. Further, when the digital camera is turned on, the remaining voltage calculator calculates a remaining voltage-level of the battery on the basis of the detected elapsed time, the last detected remaining voltage level, and the discharge characteristic of the battery. Then, the boot controller allows the digital camera to boot if the calculated remaining voltage level is larger than a limited voltage necessary to boot the digital camera.

  • Patent number: 7966508
    Abstract: A mode-switching system, comprising plural switches, a timer, and a controller, is provided. The mode-switching system switches an operation mode of a first unit to one of normal and power-saving modes. The plural switches separately correspond to plural specific functions. Each of the specific functions is carried out when the corresponding switch is switched on. The timer clocks the elapsed time since the switching operation is carried out for any of the switches. The controller switches the operation mode to the power-saving mode from the normal mode when the elapsed time exceeds a threshold value determined for the switch for which the latest switching operation has been carried out. The threshold value is determined individually for each of the switches.

    Abstract: An electronic device and method for power management in an electronic device is provided. In an embodiment, the electronic device includes the functionality of a personal digital assistant, wireless email paging and a camera with a flash that is operated via self-contained power supply in the form of a battery. The device also includes a supervisor circuit which causes the device to enter sleep mode, or disables the device, or certain features of the device, if the battery level falls below a certain threshold. A method in accordance with an embodiment performs, in response to a request to fire the flash, a pre-flash test which is selected so as to not trip the supervisor circuit. The battery level is examined after the pre-flash test. If the battery level meets certain criteria, the full flash is permitted to proceed, else the full flash is not permitted to proceed.

    Abstract: A video camera having a power-On recording standby mode, a power-On recording disabled mode, and a power-saving mode, in addition to power-OFF mode. The power-saving mode is a state in which the time taken to shift to said recording standby mode is shorter than the time taken to shift from power-OFF mode. Switching to the power-saving mode is inhibited when recording on the recording medium is not possible, thereby improving the operability of the video camera for the user. The user is prevented from attempting to record during power saving mode.

  • 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.

    Abstract: The present invention provides a system and method for timelapse capture in an image capture unit. A system and method for timelapse capture according to the present invention comprises capturing a first image automatically; initiating a sleep mode after capturing the first image; and transitioning from the sleep mode into a wake mode prior to capturing a second image. According to the present invention, a system and method is provided which provides a digital camera with the ability to automatically place the digital camera in a sleep mode during the interval when the camera is inactive. The sleep mode minimizes power consumption during inactive periods of a timelapse capture sequence, thus allowing automation of timelapse sequences. The sleep mode can be initiated if a predetermined time interval is greater than a setup time required prior to initiating the next image capture.

    Abstract: In a single use camera having a flash circuit and a film drive motor operated from a single battery source, a control circuit is provided with a diode that is coupled from a terminal on the motor control switch to the flash charging circuit to suppress operation of the flash charging circuit while the film drive motor is operating to advance the film after a picture taking event. The motor OFF position of the control switch is connected to battery positive terminal and the control circuit includes a capacitive connection from the switch to the flash charging circuit such that when the motor switch changes over from the motor ON to motor OFF position, a positive pulse is applied to restart operation of the flash charging circuit when the motor is turned off. This arrangement suppresses operation of the flash charging circuit while the motor is running, allowing full battery current to be applied to the motor.

The camera includes a power source, a controller, a film winding motor, a panorama frame driving motor, a CPU, an EEPROM, a viewfinder LCD and a timer. When the power switch is turned on, the CPU causes the panorama frame to move and changes the transmissivity of the viewfinder LCD to match the photographic screen size selected the largest number of times. When a new photographic screen size is selected using the photographic screen size switch, the number of times the photographic screen size has been selected is calculated and stored in the EEPROM. In addition, the time that has elapsed after the power switch has been turned on is measured by the timer, and when the time exceeds a predetermined value, the camera moves into the low consumption power supply mode with power still being supplied to the viewfinder LCD.
