摘要:
A photographic system comprises a camera and a film structure which can be loaded in the camera and in which photographing data can be recorded. The film structure has an image recording section in which a photographed image is recorded and a memory means for storing therein identification data peculiar to the film structure. And the camera inputs the identification data stored in the film structure into the camera and judges according to the inputted identification data whether the film structure is fit for the camera or not. Thereby, the photographing data can be recorded or read only when the film structure is fit for the camera.Further, the present invention also relates to a film structure which can be loaded in a camera having peculiar identification data so that it is judged whether the film structure is fit for the camera or not.

A film cartridge comprises a chamber in which a film is contained and a semiconductor memory such as nonvolatile memory, e.g., E.sup.2 PROM having a plurality of memory areas for storing various kinds of photographing data of each photography. In this semiconductor memory, photographing data are stored in different areas at each photographing and therefore the preceding photographing data stored in the memory are not deleted by this time photographing and photographing data of a desired film frame are accessible. Data used at a photo processing shop and a photofinishing laboratory can be also stored in the memory of the film cartridge.

A camera capable of identifying photographing conditions causative of red-eye effect making the eyes of human pictures in a flash-photographed picture come out red, and recording the identified photographing conditions in an external memory provided on a film cartridge loaded thereon. The camera recognizes the possibility of occurrence of red-eye effect on the basis of the focal length of the camera lens, the object distance, the distance between the optical axis of the camera lens and the light source of the flash light device and the object brightness. When the photographing conditions are identified to be causative of red-eye effect, a warning is displayed and flash photographing is forbidden. When photographing operation is carried out under photographing conditions liable to cause red-eye effect, information about the exposed film including the photographing conditions is recorded in the external memory to enable the subsequent developing and printing processes to correct the photograph with reference to the information.

A pseudo format camera system comprises a film cartridge including a memory which stores film speed data and limitation data, and a camera including a means for setting pseudo focal length, a means for inputting the film speed data and the limitation data from the memory, a means for controlling exposure based on the film speed data, and a means for limiting the pseudo focal length depending on the limitation data. In this camera system, the pseudo focal length can be limited based on the limitation data stored in the memory in the film cartridge, and therefore it is surely prevented that a picture becomes rough because of a bad grainness of a film.

A flashlight emitting device for a camera wherein the flash coverage of a flash device is varied, only when a mode in which flashlight is to be emitted is selected, in response to a zooming operation to assure appropriate exposure and eliminate wasteful consumption of power. The device comprises flashlight emitting means, mode changing over means operable in response to operation of a manually operable member for selecting one of a first mode in which daylight photographing is to be performed and a second mode in which the flashlight emitting means may be rendered operative to effect flashlight photographing, exposure controlling means for effecting exposure control in accordance with a selected mode, driving means for varying the flash coverage of the flashlight emitting means between a tele side and a wide side in response to a variation of the focal length of a lens of the camera, and driving controlling means for rendering the driving means inoperative when the first mode is selected by the mode changing over means but enabling operation of the driving means when the second mode is selected by the mode changing over means.
摘要:
In a camera system effective use of a single microcomputer for both automatic exposure control and automatic focus control is made possible by designing the microcomputer so that it repeats calculation for the automatic exposure control during time period for charge accumulation in a CCD focus detection sensor and during lens focusing movement and so that it performs calculation for the automatic focus control while interrupting the calculation for the automatic exposure control upon the ending of the charge accumulation in the CCD focus detection sensor and upon shifting of the lens by an amount predetermine based on the result of the calculation for the automatic focus control.

A camera of the multi-program mode type wherein a suitable program mode is selected properly in accordance with given conditions of the camera. The camera comprises a display device which displays a program mode selected by a manually operable means. When a normal program mode is selected, a microcomputer receives focal length information of an interchangeable lens mounted on the camera and automatically selects one of program lines provided for the normal program mode in accordance with the received information. Meanwhile, the microcomputer enables selection of a macro photographing program mode only when focus adjusting of the interchangeable lens is within a macro range.

In a data transmission system for a camera, a central processing unit (CPU) for controlling operation of the camera communicates with various circuit arrangements using data signals in a serial form under control of a clock signal selected in dependence upon which the circuit arrangement is the communication designation of the CPU at the time. Some of the circuit arrangements are provided in the camera while the other of the circuit arrangements are provided in accessories attachable to the camera. The CPU communicates with the circuit arrangements provided in the camera under control of a clock signal having a higher frequency for increasing the data communication speed while it communicates with the circuit arrangements provided in the accessories under control of a clock signal having a slower frequency for improving the accuracy of the data communication.
