Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a video camera equipped with a still camera, and more specifically to a movie video camera equipped with a still camera using, for example, silver halide photographic film.

BACKGROUND OF THE INVENTION While filming with a television camera, ie, a video camera, that has a videotape recording function, there has been a desire to record a particular scene as a still photograph. conventionally,
For example, I would carry both a silver-halide still camera and a video camera, and if I wanted to shoot a still scene while shooting with the video camera, I would stop shooting with the video camera and shoot with the still camera. In such a situation, you have to carry two devices, you have to stop recording with a video camera, and there is a risk of missing out on an important photo opportunity. There was a problem.

Therefore, in order to solve this problem, a still camera and a video camera are combined into one device, and a still camera is installed that allows you to operate the still camera and take still pictures without interrupting the video camera. A video camera will be required.

Even in such video cameras with still cameras,
For still and video photography, a focusing function is required to automatically measure the distance to the subject and adjust the position of the photographic lens.

For example, triangulation-based distance measurement is used to measure the distance to the subject. In the case of the active method, the camera emits infrared light from the light emitting part, and the light receiving part detects the infrared light reflected back by the subject.
The distance to the subject is measured by detecting the angle of incidence of infrared light from the subject onto the light receiving unit. Therefore, the amount of infrared light from the subject varies depending on the distance to the subject.
In order to vary the angle of incidence of the light onto the light receiving section, it is necessary to provide a predetermined distance between the light emitting section and the light receiving section of the camera.

In the case of the passive method, the camera is provided with two light receiving sections, light from the subject is made incident on each light receiving section, and the distance to the subject is measured by detecting the difference in the angle of incidence. Therefore, it is necessary to provide a predetermined distance between the two light receiving sections.

Therefore, when providing a light emitting section and a light receiving section for distance measurement, or when providing two light receiving sections, it is required to provide a distance between them.

OBJECTS In view of these demands, it is an object of the present invention to provide a video camera with a still camera that is convenient to carry, has good operability, and can perform distance measurement appropriately.

DISCLOSURE OF THE INVENTION A video camera with a still camera according to the present invention includes a casing having an approximately rectangular parallelepiped shape as a whole, and an imaging optical system for a still camera and an imaging system for a video camera that are located in the front of the casing and have openings facing the same field of view. optical system and

Controls 4B.

The apparatus is provided with an automatic exposure (EE) sensor 148,
This measures the brightness of the scene and provides data indicative of the measured value to the system control circuit 144. The system control circuit 144 controls the exposure control circuit 110 and the strobe light emitting circuit 146 in accordance with the brightness data of the object field input from the EE sensor 148.

In response to this, the exposure control circuit 1!0 adjusts the aperture of the aperture 118 of the video camera, and also controls the aperture of the aperture 104 of the still camera and the opening time of the shutter 10B. Further, the strobe light emitting circuit 146 controls the light emission time of the D strobe light emitter 18.

08, 210 Incoming cell. The distance measurement CC0182 is covered with a wedge-shaped mask, so it receives 20% of reflected infrared light.
Since the amount of incident light differs depending on the incident angle of 8, 208, and 210, the output changes. On the other hand, reference GC0184
Since the mask is not covered, the reflected infrared light 208
, 208 and 210, the amount of incident light does not change depending on the incident angle, so the output is constant.

The distance determination circuit 162 receives the above distance measurement CC0182 and the output 212 of the reference GCD 184 from the CCD line sensor 1flO, and determines the distance to the object by comparing the levels of these signals. Therefore, the reflected infrared light 206°208, 21 depending on the distance of the subject
The larger the difference in the angle of incidence of 0, the higher the CCD line sensor 1f.
Since the difference in the incident position to tO is large, the distance to the object can be accurately measured. The larger the distance #l between the AF light emitting element 20 and the AF light receiving element 26, the greater the difference in the incident angles of the reflected infrared light 206, 208 and 210 according to the distance of the subject. It is desirable to keep a distance from the element 26 as much as possible.

AF light emitting element 20. ! - The distance l from the AF light-receiving element 28 corresponds to these distances arranged on the front surface 12 of the casing 10, as shown in FIG. 1, in this embodiment. As can be seen from FIG. 1, in this embodiment, the AF
Since the distance l between the light emitting element 20 and the AF light receiving element 26, that is, the base line has a length of one minute, accurate distance measurement can be performed.

The distance measurement data output from the distance determination circuit 162 is input to the system control circuit 144, and the system control circuit 144 controls the focusing mechanism 112 according to the distance data between the device and the subject.
, thereby controlling the two imaging lenses 14 and 1B.
The focus of the image is adjusted.

The device is also provided with a white balance sensor 152. This detects the color components of the incident light from the subject and provides the data to the system control circuit 144. The system control circuit 144 sets parameters for the white balance adjustment circuit of the imaging circuit 120 based on this data.

Referring now to FIG. 3, this figure schematically shows the interior of the apparatus in the state shown in FIG. 1 with the casing 10 removed. Inside the housing 28 of the casing lO,
It is mainly equipped with a still camera function section 76.

Behind the imaging optical system unit 66 including the imaging lens 14 of the video camera, a solid-state imaging device 118 is mounted on an electronic circuit board 68 and disposed as shown in the figure. Parts related to video camera functions such as a mechanism 112, automatic photometry and distance measurement circuits are also implemented. Further behind it, a video circuit 120

As described above, in this embodiment, the imaging lenses 14 and 16 are opened at the front surface 12 of the casing 10, and the still camera section and the video camera section are housed within the casing 10.

Therefore, it is possible to simultaneously capture a moving image using a video camera and capture a still image using a still camera without interfering with each other.

Further, the AF light emitting element 20 is arranged at the lower left end of the front surface,
Since the AF light receiving element 26 is arranged at the upper right of the imaging lens 16 of the still camera, the AF light emitting element 20 and the AF light receiving element 28 are arranged apart from each other. As a result, the length l of the base line in FIG. 7 becomes longer. Therefore, the difference in the incident angles of the reflected infrared lights 206, 208 and 210 depending on the distance to the object becomes large, so that the distance to the object can be accurately measured.

Another embodiment of the invention is shown in FIG.

In this embodiment, as shown in the figure, AF light receiving elements 27 and 28 are arranged at the lower left end of the front surface 12 and at the upper right corner of the imaging lens 1B of the still camera. AF light emitting element 20 provided in the embodiment shown in FIG.

Reflects the light from 8B and sends the reflected light to CCD line sensor 1
70 and 172, respectively. Reflection mirror 1
Since the light reflected by 84 always enters the reflecting prism 188 from a certain direction, it is reflected by the reflecting prism 168 in a certain direction and enters the CCD line sensor 170 at a certain angle.

On the other hand, the light reflected by the rotating reflective mirror 18B is reflected at different angles depending on the distance to the subject 86, 88, and 80, is reflected by the reflective prism 168 in a direction according to the incident angle, and is sent to the CCD line sensor 172, respectively. incident at different angles.

The C and CD line sensors 170 and 172 each output an output to a comparator 174 according to the angle of incident light. The comparator 174 compares these two inputs and outputs a signal 222 resulting from the comparison to the distance determination circuit 17B.

A signal indicating the amount of rotation from the rotating reflection mirror 166 is also input to the distance determination circuit 176 .

In such an AF sensor, the subject 86.88.8
When light enters the AF light receiving elements 27 and 26 from 0, it enters the CCD line sensors 170 and 172, respectively, as described above. A comparator 174 compares the outputs from the CCD line sensors 170 and 172, and when they differ, the rotary reflection mirror 18B is rotated by a drive means (not shown), and the outputs from the CCD line sensors 170 and 172 are compared.
and 172 so that they match. When the outputs from the CCD line sensors 170 and 172 match according to the output 222 from the comparator 174, the distance determination circuit 17B determines the position of the subject 88, 88, 90 according to the output 230 indicating the position of the rotating reflective mirror 166.
