  • Patent number: 6766111
    Abstract: A camera system having a camera body and a photographing lens, which can be mounted to and dismounted from the camera body, includes a determining device which determines a type of the photographing lens in accordance with data received from the photographing lens; and a body controller which has a function to send body data and individual function data to the photographing lens, wherein each of the individual function data is required for a corresponding function that the photographing lens possesses. The body controller sends all the body data to the photographing lens regardless of the type of the photographing lens, and sends a portion of the individual function data which is associated with the type of the photographing lens to the photographing lens.

  • Patent number: 6741808
    Abstract: A camera system includes a photographing lens having a lens memory and/or a lens controller, and a camera body including a body controller which can communicate with the lens memory and/or the lens controller; a first power and a second power which can be supplied to the photographing lens. The lens memory and the lens controller operate with the first power and the second power, respectively, when the photographing lens is mounted to the camera body. The body controller supplies the first power to the photographing lens to drive the lens memory to read data from the lens memory, and subsequently disables the lens memory and supplies the second power to the lens controller so that the body controller and the lens controller communicate with each other if the body controller determines, from the lens data, that the photographing lens includes the lens controller.

  • Patent number: 6734895
    Abstract: A digital camera has a mounting part to mount a shooting lens or other optical equipment, and includes a mode switch that changes between a mode that shoots using the shooting lens and a mode that shoots using the other equipment. The camera includes an information interface that communicates with the shooting lens or with the other equipment, and receives information from the shooting lens or from the other equipment corresponding to the set mode. A camera controller controls the camera to change a type of information received through the interface from the shooting lens or from the other equipment based upon the set mode. When changed to the mode that shoots using the other equipment, the interface receives information corresponding to a color temperature or a brightness of a light source of the other equipment, and the controller controls the camera shooting state based upon that received information.

  • Patent number: 6734912
    Abstract: In a TV lens system including a TV lens apparatus and a control unit, CPUs of the TV lens apparatus and the control unit monitor intervals between received data in serial communication in a digital control mode. If the data transmission stops for a predetermined time or the received data has an error, the CPUs determine that the communication is abnormal and switch the control modes of the TV lens system from the digital control mode to an analog control mode by operating switching devices. Display units show that the system has been switched to the analog control mode. If the CPUs detect the communication being abnormal, they may display abnormality of the communication on the display units to inform the user of the abnormality of the communication so that the user can switch the control modes by manually operating analog setting switches. Information indicating the abnormality of the communication is stored in an EEPROM, and presented to the user when the TV lens system starts to operate afterward.
