    Abstract: An image capturing device includes a first controller operable to control image capturing; an operation section including a switch; a detector operable to detect a change to an image capturing mode and to send a signal representing the change; a second controller operable to monitor and process the sent signal, the second controller having a power consumption less than that of the first controller; and a power supply operable to supply power to the first controller, the second controller, and a functional section of the device. When the second controller receives the signal sent from the detecting section in a power saving state in which power is supplied from the power supply to the second controller, the power saving state is changed to a power supplying state capable of image capturing by supplying power from the power supply to portions of the device including the first controller.

  • Patent number: 8159601
    Abstract: A sequential shooting controller includes both high and low load drive modes, and first and second power-voltage detectors. The high/low load drive modes drive a device under high/low loads. The first power-voltage detector detects a power-voltage by connecting a load. The second power-voltage detector detects the voltage across the device. The first power-voltage detector is actuated at the beginning of sequential shooting before a first image capturing operation starts. The high load image capturing operation starts when the voltage detected by the first power-voltage detector is higher than a first threshold. The low load image capturing operation starts when the voltage detected by the first power-voltage detector is lower than the first threshold. The second power-voltage detector is driven during a high load image capturing operation. The second power-voltage detector is disabled during a low load image capturing operation.

  • 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: 8059192
    Abstract: A method and apparatus for maintaining a maximum sustained flash current over the whole length of a flash using a programmable current drive in a handheld portable device powered by a battery. The method involves measuring the battery voltage before and after a flash is initiated and calculating the equivalent series resistance (ESR) of the battery. The calculated ESR is then used to adjust the flash current. The process may be repeated to correct for errors in the flash current.

  • Patent number: 7990466
    Abstract: A method of auto-retracting a lens of an image capture apparatus and a control system using the same are applied to an image capture apparatus with a retractable lens. The method includes the following steps. A hardware circuit of the image capture apparatus detects whether an abnormal power failure event occurs or not. The hardware circuit performs a re-boot procedure when detects that the abnormal power failure event occurs. After the hardware circuit performs the re-boot procedure, software in the image capture apparatus utilizes residual power only to perform a control procedure of retracting the lens. After the retractable lens is detected to have been retracted into the image capture apparatus, the software controls the image capture apparatus to be powered off.

  • Patent number: 7983554
    Abstract: In a camera, air orifices for linking the space inside a cell compartment with the outside of a casing are disposed in a position other than the grip portion which is held by a user, in the vicinity of the center of the front surface of the casing, that is, in the vicinity of a lens-barrel. A concave-convex portion serving as an air orifice guard is formed at the side opposite to that where the lens-barrel is disposed with respect to the air orifices. As a result, even when the user takes a picture of an object by holding the camera with his/her own hand, the air orifices are prevented from being closed by the user's hand. Oxygen (air) can be constantly supplied to the fuel cell accommodated inside the cell compartment, and the fuel cell can continuously generate a sufficient quantity of electricity.

  • Patent number: 7970272
    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.

  • Patent number: 7899418
    Abstract: A mobile device is equipped with a transmitting function to transmit data. When a power switch is turned off during data transmission, a transition is made to a transmission-during-power-off mode that continues data transmission. The transition to the transmission-during-power-off mode is performed when an inquiry is made on a screen as to whether transmission will be performed and “continue” is subsequently selected. In this mode, even when the mobile device with the power switch being turned off is carried around, data transmission is continued and data is recorded into a storage section of a home personal computer.
