An image capturing apparatus comprising an image sensor including image forming pixels each of which generates a signal for image generation, and focus detection pixels each of which generates a signal for phase difference detection, readout means for reading out the signal of each pixel of the image sensor, focus detection means for detecting a focus by a phase-difference detection method using the signals for phase difference detection from the focus detection pixels, and switching means for switching a combination of the focus detection pixels to be used for focus detection by the focus detection means between a case in which the readout means reads out the signals of the pixels of the image sensor after thinning-out and a case in which the readout means reads out the signals of the pixels of the image sensor without thinning-out.

Image capturing apparatus

An apparatus, such as a camera, adapted for a film having a magnetic recording part includes a detecting device which detects perforations of the film, a magnetic head which performs at least one of reading and writing of information from or into the magnetic recording part of the film, and a microprocessor which performs processing of a signal detected by the detecting device and processing of a signal read or to be written by the magnetic head, wherein the microprocessor A/D-samples the signal detected by the detecting device.

Camera capable of using film having magnetic recording part

The present invention relates to a camera capable of recording information indicative of an instruction to inhibit automatic printing on a film and, more particularly, to a camera capable of automatically recording information indicative of an instruction to inhibit such automatic printing, if photography unsuited to the automatic printing is performed for not less than a predetermined number of exposed frames of the film.

Camera capable of recording information relative to printing processing

A control apparatus for a camera using an image recording medium having at least one index mark and a plurality of frames, the control apparatus includes frame transporting portion for effecting the frame transportation of the image recording medium, a detecting portion for detecting an index mark provided for the image recording medium, a determining portion for determining the presence of a final frame, and a control portion for effecting a predetermined control operation by the detecting portion detecting the initial index mark after the frame transportation of the final frame is started by the frame transporting portion, in response to the determining portion determining the final frame.

Control apparatus for a camera with an index mark detection feature

The present invention relates to a camera for performing magnetic recording in a magnetic track on a film. In such a camera, the type of the film is judged, and data necessary for printing is prohibited from being recorded when the film is a positive.

Camera having a magnetic information recording apparatus and recording

In a camera arranged to use a film cartridge having a rotary member which rotates in association with transport of a film and which is provided with a code indicative of information about the film, a rotating state of the rotary member is detected in rewinding the film, so that the film can securely be wound into the film cartridge.

Camera

A camera of the kind making a discrimination between exposed and unexposed states of each of frames of a film by detecting information recorded in a magnetic recording part provided at each of the frames is arranged to detect the information twice for one and the same frame by causing the film to be transported in different directions and to finally decide the state of exposure of the frame according to whether the results of the detection made twice coincide with each other or not, so that the discrimination can be accurately carried out.

Camera adapted to use film having magnetic recording part

This invention relates to a camera for recording preset aspect ratio information on each shot frame. In this invention, there is provided a camera of this type, which has a first mode for recording the preset aspect ratio information on frames in units of shooting operations, and a second mode for recording specific aspect ratio information regardless of the preset aspect ratio information on frames after the preset aspect ratio information is recorded on the shot frame, and can select one of the first and second modes.

Camera having magnetic recording apparatus

Camera apparatus capable of restricting the number of intermediate rewinding operations of a film into the film cartridge includes intermediate rewinding structure for rewinding the film into the film cartridge at a stage where a portion of the film frames has not yet been exposed. Restriction circuitry is provided for restricting the number of intermediate rewinding operations permitted to be performed on said film by said intermediate rewinding structure.

Camera in which the number of film rewinding operations may be restricted

A camera using film having a magnetic memorizing portion that includes a plurality of frames. The camera includes a writing device for writing the same information onto the same frame of the magnetic memorizing portion a plurality of times, and a varying device for automatically varying the number of times of writing by the writing device in conformity with the substance or degree of importance of the information.

Camera using film with a mangetic memorizing portion

A data imprinting device of the type in which data are imprinted on the film surface during the time when the film is transported. The device includes a data exposure device positioned on the presser plate which presses the film against the film gate of the camera in fixedly secured relation at a location corresponding to the vicinity of the path of movement of the film and a prohibitor responsive to accidental interruption of the film transportation for prohibiting further imprinting of data until the next frame, which came across the data exposure making device at the time of the accidental interruption, is brought into alignment with the data exposure making means as the film transportaion has been re-started.

Data imprinting device

A camera system of the kind arranged to store a lens position obtained at a specific point in time prior to automatic focusing by an automatic focusing device and, when an operation member is operated, to forcedly shift the lens to the stored lens position independently of the automatic focusing action is characterized in that:

Camera system

A display apparatus includes a display unit in which a number of digits for display is finite, a memory for storing a plurality of display items each having a predetermined number of digits for display, a display item selecting unit for selecting at least one display item from among the display items stored in the memory so as to display the same in the display unit, and a display controlling unit for effecting control so as to display on the display unit the display item selected by the display item selecting unit. When a display item having a number of digits exceeding the final digit of the display unit is selected, the display controlling unit inhibits the display of the display item concerned.

Display apparatus

An information setting device for a camera comprises a plurality of manual operation switches for setting varied kinds of information. Among these switches, when a plurality of switches are simultaneously operated, there obtains a specific setting mode for setting information of a kind different from information of other kinds to be set by individually operating these switches. In the event of thus selecting the specific setting mode, this mode remains unchanged even when at least one of the simultaneously operated switches becomes inoperative.

Information setting device for camera

The present invention relates to a photographic information setting device having a switch arranged to turn on and off and generate digital data when a stepwise operating member changes its position, wherein the turning on and off of the switch is detected with the help of current supply to the switch to renew the digital data until a desired value of any exposure factor is preset. In the present invention, when the aforesaid stepwise operating member lies in any of click-stopped positions, the current supply to the switch is cut off to prevent wasteful consumption of electrical energy. The number of times of turning on and off of the switch is once stored in a counter, and, upon detection of turning on and off of the switch, a computer reads out the content of the counter so that the renewed digital data are formed in the interior of the computer.
