  • Patent number: 5614968
    Abstract: A camera system comprises by a camera main body and a film loaded in the camera main body and having a magnetic recording portion. Data for commanding a printer apparatus to perform trimming exposure is recorded on the magnetic recording portion of the film in advance. A feed mechanism feeds the film. A manual operation member is arranged on the outer surface of the camera main body. In the camera main body, a permanent magnet moves, upon manual operation of the manual operation member, between a position where the magnet opposes the magnetic recording portion of the film and a position to which the magnet is caused to retreat from the magnetic recording portion. When a film feed operation is performed by the feed mechanism while the permanent magnet is set at the position where it opposes the magnetic recording portion, the permanent magnet erases the trimming command data recorded on the magnetic recording portion, thereby prohibiting the printer apparatus from performing trimming exposure.

  • Patent number: 5196929
    Abstract: In a display apparatus of a camera according to this invention, an imaging device repeatedly images an object to be photographed and generates a two-dimensional luminance signal. A one-dimensional pattern signal is repeatedly generated from the two-dimensional luminance signal for at least one of inside or outside the imaging device. Each time a new pattern signal is generated, the immediately preceding pattern signal is stored in a frame memory. After the immediately preceding pattern signal is stored in the frame memory, a CPU performs a correlation arithmetic operation between a new pattern signal and the immediately preceding pattern signal stored in the frame memory. The CPU detects a moving amount of the object to be photographed according to the movement of the camera during the repetition time period, and performs the correlation arithmetic operation each time the frame memory stores an immediately preceding pattern signal.

  • Patent number: 5146071
    Abstract: A plurality of lens groups are moveable in the direction of an optical axis. A plurality of motors are provided for the lens groups, respectively. A driving circuit drives the motors. A switching section sequentially selects the motors and connects the selected motors to the driving circuit. A lens position-detecting section detects the positions of the lens groups. A driving control section sequentially drives the lens groups in accordance with intermediate target position data, respectively, via the switching section and the driving section, and determines whether the lens groups have reached their respective intermediate target positions, on the basis of the detection performed by the lens position-detecting section. When the driving control section determines that the lens groups have reached their respective intermediate target positions, it demands next intermediate target positions, which are slightly away from the initially-determined intermediate target positions.

  • Patent number: 4857951
    Abstract: An output device for range information for use in an interchangeable lens includes a range ring of the interchangeable lens which is first preset at an extreme position, namely, a position at infinity or at close range, and a CPU disposed in the interchangeable lens for producing absolute range information relative to the extreme position on the basis of pulses which are generated in response to data stored in the CPU and rotating of the range ring. A camera system includes rotatable and manually operable operating members which are located on a camera accessory. Rotation of the operating members results in the generation of pulses and the rotation detection device uses the pulses for detecting rotation of the operating members. An output from the detecting means serves to control a motor drive to focus an interchangeable lens.

  • Patent number: 4745428
    Abstract: When establishing a program exposure response of a camera, an EV value is calculated from the brightness of an object being photographed, a film speed and the like, and a programmed calculation is made on the basis of a preset program response and the EV value to determine an exposure period and a diaphragm aperture in the absence of a program shift input. However, in the presence of a program shift operation, the relationship between an exposure period and a diaphragm aperture is shifted through a given number of steps, and a new program response is established so that the exposure period and the diaphragm aperture varies according to an EV value from their shifted value, thus determining an exposure control value.

  • Patent number: 4598986
    Abstract: An apparatus for exposure correction is provided for use with a camera of automatic exposure control type. An amount of exposure which is determined on the basis of an output from photometric means is shifted by a given correction value toward overexposure or underexposure in response to the operation of a manual operating member. The correction value can be varied either automatically or manually. The correction value can be changed by automatically reading information given on a film or a film container and representing a film latitude, by manually supplying a film latitude value, or by utilizing information representing a film speed which has a correlation with a film latitude. In this manner, a photograph having an improved gradation can be obtained by effectively utilizing a film latitude.
