  • Patent number: 10649318
    Abstract: A monitoring camera which has a lock mechanism, which is capable to unlock a lens 1 even if power supply is stopped due to blackout. The lock mechanism includes a lock member 11 having a region 11b which is pushed by an operation member 3 in a state where a lock pin member 12 engages with the lens 1, a biasing member 13 biasing the lock member 11, and magnetic force generating units 10 generating magnetic forces by electro energization, to move against the biasing force so that the region 11c faces the operation member 3. While the magnetic forces are not generated in a non-electro energization state, the operation member 3 pushes the region 11b and thus moves the lock member 11 and the lock pin member 12 so that the lock pin member 12 is released from the lens 1.

    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.

    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 After the retractable lens is detected to have been retracted into the image capture apparatus, the software controls the image capture apparatus to be powered off.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.

  • Patent number: 7777809
    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: 7773147
    Abstract: A method for predicting the quantity of pictures that can be taken is applied to a picture-taking function of a digital still camera. Firstly, a lookup table is individually built for different power using operations of a battery according to the operational modes of the picture-taking function. Next, the method looks up the corresponding lookup table according to an obtained battery voltage value of the digital still camera and the operational mode. Finally, a quantity of pictures that can be taken is obtained from the lookup table, and is displayed on a display unit of the digital still camera and is provided to the user. Thereby, the user can change the operational mode to reduce power consumption and take more pictures.

  • Patent number: 7720376
    Abstract: A method and system for determining camera positioning information from an accelerometer mounted on a camera. The accelerometer measures the orientation of the camera with respect to gravity. Orientation measurement allows user interface information to be displayed in a “right side up” orientation on a viewfinder for any camera orientation. Alternatively, an artificial horizon indicator may be displayed in the viewfinder. The accelerometer may also measure camera movement. Camera movement information together with camera orientation can be used to determine camera usage. Additionally, camera movement information can be used to determine a minimum shutter speed for a sharp picture.

  • Patent number: 7677818
    Abstract: In a main body of a camera, a recording unit is disposed which is capable of recording specific information of a photographing lens or an accessory. When the specific information of the presently attached photographing lens or accessory has been already registered in the recording unit, the main body of the camera does not acquire all the specific information from the attached photographing lens or accessory by data communication. In a case where the specific information of the attached photographing lens or accessory has been registered in the recording unit, the only identification information of the interchangeable lens or accessory can be enough, even if the data communication is necessary. In consequence, a communication time with respect to the interchangeable lenses or various types of accessories can be reduced as a whole.
