摘要:
An automatic exposure control system permitting for a photographic camera to make an exposure in either of the shutter preselection automatic exposure range and the diaphragm preselection automatic exposure range is established by combination of an adapter unit with the camera. This adapter unit has a housing attachable to and detachable from the camera body, and includes an exposure operation and control circuit capable, upon preselection of an exposure time, of deriving an exposure value representing an effective exposure aperture, and, upon preselection of diaphragm value, of deriving an exposure value representing an exposure time. Responsive to the output of the adapter unit, the control device in the camera body controls operation of the shutter and diaphragm mechanisms thereof selectively in accordance with the exposure value derived from said exposure operation and control circuit. The provision for permitting the camera to make an exposure in an automatic flash exposure range is also made at the exposure operation and control circuit of the adapter unit in a manner to determine the period of energization of a flash unit associated with the camera.

In a combination of a photographic camera with an accessory equipment such as a motor drive unit attached thereto, when the voltage of a power source or battery provided in the camera for application to an automatic exposure control circuit thereof has fallen below a satisfactory operating level, a transfer switch is automatically operated to shift the connection of the exposure control circuit from the battery of the camera to an electrical power source or battery provided in the accessory equipment.

In a camera adapted for use with a motor drive unit capable of selectively controlling film winding and rewinding operations, there are provided first and second driving torque input means, the first input means being positioned for continual engagement with a film winding up mechanism, and the second input means being arranged upon setting movement of a manually operated rewinding knob to attain driving engagement with a rewinding shaft and being located outside a film cartridge chamber to insure the protection of the film from fogging. The motor drive unit has a pair of output means connected through respective directionally-responsive clutches to a common motor and arranged upon attachment to the camera to engage the respective input means of the camera and has a single operating member for selectively actuating each of the output means for the film winding and rewinding operation.

A camera equipped with a shutter preselection automatic exposure range and a diaphragm preselection automatic exposure range is automatically switched to the shutter preselection mode when the camera is assembled with a motor drive unit which is set in RUN position, whereby it is insured that a series of successive frame exposures can be made at a predetermined frame frequency.

A motor driven photographing control circuit for a double preference type automatic exposure control camera which is used for continuous photographing with a motor drive device attached thereto. When a sum of the shutter time computed by a shutter time computing circuit and the length of time required for a winding operation become longer than a preset photographing cycle in carrying out such continuous photographing, an alarm is displayed giving a warning that photographing in the preset cycle is not possible. Concurrently with this, a stop preference mode of photographing is shifted to a shutter preference mode and the shutter is controlled to be operated at a preset length of time, so that continuous photographing can be accomplished in a set cycle.

A camera in which the iris is set prior to the exposure time, particularly a camera which can be converted into a camera in which the exposure time is set prior to the iris adjustment by mounting an additional iris control device on the view finder.

In a photographic camera for use with a single-reel magazine wherein the film after withdrawn by a film advancing sprocket for exposure purposes has to be transported backwards to the magazine while the sprocket being idle, a mechanism for releasing the sprocket from braking engagement with a drive member therefor is provided with two control or rewinding buttons arranged to be manually actuable from the outside of the camera housing at respective places, one of which is located in a recess of the bottom panel thereof so that, for example, when a motor drive unit is attached thereto, an automatic responding relationship is established therebetween, and another place which is located so that, while the user is unabled to make use of the first-named rewinding button, as, for example, a tripod remains left in attachment with the camera at its bottom panel, it is made possible to switch the camera from the film winding to the rewinding state.

An electrically operated extrinsic coordinating system for the light metering and exposure controlling circuits of a photographic camera, the camera also having incorporated therein an intrinsic coordinating system for those circuits, comprises first and second electronic switches connected in the respective power supply circuits for the light metering and exposure controlling circuits through respective interconnection channels to shunt the first and second switches of the intrinsic coordinating system, a delay circuit connected between the first and second electronic switches, and an operating switch arranged to be accessible from the outside of the camera and cooperative with the first electronic switch upon manual closure of the operating switch to actuate the light metering and exposure controlling circuits for the power supply in predetermined time-displaced relation to each other independently of the intrinsic coordinating system.

Provided is an image editing device that enables a user to easily assign images to a plurality of pages of an album or the like so as to satisfy editorial restrictions. The image editing device acquires a plurality of pieces of image data; determines, based on respective photographed times of the plurality of pieces of image data and a reference time interval, details of an assignment of the plurality of pieces of image data to each of the plurality of pages so that an interval between photographed times of pieces of image data to be assigned to the each of the plurality of pages is the reference time interval or smaller; and outputs image output data on the each of the plurality of pages based on a result of the assignment.

The disclosed is an arteriosclerosis evaluating apparatus capable of easily separating pulse wave data detected at one measurement site into an incident wave and a reflected wave and capable of easily determining and evaluating the degree of arteriosclerosis. The pulse wave transmitted through an artery is detected at one site of a living body by a pulse wave detection device, and the detected pulse wave is fitted with a fitting function by a breakdown device so that the detected pulse wave can be broken down into an incident wave and a reflected wave. The degree of arteriosclerosis is evaluated from the amplitude intensities (i.e., peak intensities) of the incident wave and the reflected wave broken down from the pulse wave.
