摘要： A camera system includes a data source provided in a camera accessory such as an interchangeable lens and a micro-computer in a camera body. A requesting data for requesting particular data related to the lens is sent from the camera body to the lens, whereby the lens produces the particular data and sends it to the camera body. By the use of the particular data from the lens and other data obtained from the camera body, the micro-computer carries out exposure calculations and controls the camera based on the calculated result.

摘要： A camera system operable with data carried from a camera accessory to a camera body. The camera accessory has a ROM for storing various data at a plurality of addresses, respectively, each of which data consists of a plurality of bits, and a coupling terminal for receiving a train of clock pulses from the camera body. A circuit is also provided for sequentially designating the address of the ROM one by one to permit the ROM to output a data stored at the designated address. In the circuit, an address signal is formed in response to the clock pulses, received through the coupling terminal, for designating an address. The data derived from the ROM are transmitted to the camera body. The camera system can operate under different modes of exposure control and can identify the attachments of accessories as to their capacity to be responsive to different forms of exposure control systems, particularly when the attachment will either permit or prevent control of an aperture value from the camera body.

摘要： A camera system comprising a camera body and an interchangeable lens assembly adapted to be coupled to the camera body. The interchangeable lens assembly has no manipulatable aperture adjusting ring, but has an aperture mechanism and a read-only memory both built therein. The read-only memory stores therein various data peculiar to such lens assembly. The camera body communicates with and power the lens assembly through a set of terminals connectable with associated terminals provided in the lens assembly. The terminals in each of the camera body and lens assembly are arranged in a generally arcuate row with the data transmitting terminal located at one extremity of the arcuate row on the leading side with respect to the direction of turn of the lens assembly which is effected when the lens assembly is to be completely coupled to the camera body.

摘要： A camera has an automatic data reading arrangement for reading ISO data provided on a film cartridge. When a main battery is exchanged with an old battery while the film is still loaded in the camera, ISO data is maintained in a memory supported and powered by a back-up battery. If such an ISO data is not available after the exchange of the main battery, ISO data again read from the loaded film cartridge is employed. If the film is not the type that can provide an ISO data, the most widely used ISO data will be automatically set for the further exposure calculation.
摘要翻译：相机具有用于读取暗盒上提供的ISO数据的自动数据读取装置。当主体电池与旧电池交换时，胶片仍然装入相机中时，ISO数据保持在支持的存储器中并由备用电池供电。如果在更换主电池之后这样的ISO数据不可用，则使用从装载的暗盒读取的ISO数据。如果电影不是可以提供ISO数据的类型，则最广泛使用的ISO数据将被自动设置用于进一步的曝光计算。

摘要： A camera capable of AE-lock photography wherein an output of a light measuring circuit is stored in response to a manual operation at an arbitrary time prior to a shutter release operation, and exposure is controlled in accordance with the stored output. AE-lock switch is interposed between a light measuring circuit and a first storage capacitor, while a buffer circuit is interposed between the first storage capacitor and a second storage capacitor. Exposure is controlled in accordance with the charged voltage of the second storage capacitor. The above mentioned buffer circuit is connected with a switch means which supplies power for a given short period at an initial stage in conjunction with a shutter release operation whereby the second storage capacitor is charged to the voltage of the first storage capacitor during that given period.
