Abstract:
The present invention provides a distance-measuring device has an AF area sensor that includes an image pick up element formed on a semiconductor substrate for receiving two images having a parallax therebetween, and a photo reception signal processing circuit formed on the semiconductor substrate for processing signals corresponding to light received by the image pick up element. On the basis of sensor data (outline data) obtained by integration executed in the AF area sensor in an outline detection mode, the distance-measuring device detects a main subject in a photography screen, sets a distance-measuring area including the main subject, and measures a distance to the main subject.
Abstract:
A photographing composition determination apparatus of an electronic camera includes an area sensor having a plurality of light receiving elements and disposed in an area shape so as to correspond to a photographing scene. A light receiving lens introduces an object image to the area sensor. An A/D converter converts analog signals output from the respective light receiving elements of the area sensor into digital data. A CPU detects the distribution of luminance and the distribution of distances in the photographing scene based on the digital data output from the A/D converter and determines a photographing composition according to the distribution of the luminance and the distribution of the distances.

A camera comprises an optical photographing system, an image pickup device which receives a luminous flux via the optical photographing system to output image data, a monitor on which an image is displayed based on the image data, an actuator which controls a position of the image pickup device to obtain the image data in which an influence of camera shake is reduced, and a camera shake detecting section which detects a camera shake state. In the camera, the image data at the time of non-operation of the actuator is processed/formed from the image data obtained at this time and the camera shake state detected by the camera shake detecting section, and a control is executed in such a manner that the image data at the time of the non-operation of the actuator and the image data at the time of operation of the actuator are displayed on the monitor.
Abstract:
A camera comprises a monitor which allows a composition of a subject to be confirmed, a backlight which illuminates at least one region on the monitor, an image pickup device and a distance measuring unit for detecting an image condition of the subject, and a backlight control unit which changes the region to be illuminated by the backlight, in accordance with a detection result from the image pickup device and the distance measuring unit.
Abstract:
A camera according to this invention includes a backlight judgment section which determines whether the photographic scene is against light by comparing the average luminance of the entire photographic screen obtained by photometry with the luminance of the main subject at a distance-measuring point selected by distance measurement. With the backlight judgment section, the camera performs suitable exposure control accompanied by illumination, such as supplementary light, at the time of exposure in a photographic scene where the main subject is against light.
Abstract:
A distance-measuring apparatus for a camera comprises an area sensor, an integration circuit, and a switching circuit. The above-mentioned area sensor receives light of a picture image in the image plane. The integration circuit integrates output signals of this area sensor. The control circuit controls operations of starting and stopping the integration of the above-mentioned integration circuit, based on output signals corresponding to a specific block of the above-mentioned area sensor. The switching circuit switches the above-mentioned specific block according to using state of the camera.
Abstract:
In a camera of this invention, the first candidate point of a plurality of points in a frame is determined by a first release switch, and the second candidate point of the plurality of points which is different from the first candidate point is selected by a second release switch. The operation of a predetermined switch by a photographer is detected by a switch. A BCPU selects/switches the first or second candidate point in accordance with the state detected by the switch.
Abstract:
There is disclosed a distance measurement apparatus of a camera which obtains subject distance information (phase difference of a subject luminance signal) of each distance measurement area by a photoelectric conversion element with a plurality of distance measurement areas including a peripheral region outside a region to be photographed arranged therein, divides the distance measurement areas having numeric values in a predetermined range and being adjacent to one another into groups from the obtained subject distance information, excludes the group extending into the region to be photographed, performs distance measurement operation processing of a major subject by a distance measurement result of the group existing only in the region to be photographed, selects a result indicating a closest distance from distance measurement results, and obtains a final distance measurement output.
Abstract:
A camera with self-timer photographing function has a release button for a release switch operation, a self-timer photographing mode switching button, and the like. A photographing mode for a scene in which only a photographer enters a screen and a photographing mode for a scene in which a plurality of persons are an object to be photographed are switched by the mode switching button in photographing in a self-timer photographing mode. Photographing is executed by an AF (AUTOMATIC FOCUSING) operation performed a self-timer time after in the former mode, photographing is executed by an AF operation performed immediately after a release switch operation in the later ode. According to this camera, in the self-timer photographing, photographing with a correct focus for the state of an object can be always performed without checking the focus in photographing or checking a distance measurement target in a finder.
Abstract:
A light-emitting section projects distance measurement light toward an object to be photographed. A switching section sequentially switches the projection direction of the distance measurement light projected from the light-emitting section. A first light-receiving section is arranged at a position separated from the light-emitting section by a first base length. The first light-receiving section receives a reflected light beam of the distance measurement light from the object and outputs a first signal corresponding to the incident position of the reflected light beam. The second light-receiving section receives a reflected light beam of the distance measurement light from the object and outputs a second signal corresponding to the incident position of the reflected light beam. An object distance calculating section calculates the object distance in accordance with first and second signals corresponding to the incident positions and output from the first and second light-receiving sections.
