- the distance measuring unit is an optical distance measuring unit. Therefore, distance measurement can be performed quickly and accurately without contact.
- any known means such as a triangulation method can be applied.
- the present invention described in claim 23 is the imaging device according to any one of claims 16 to 21, wherein the distance measuring unit is an ultrasonic distance measuring unit. Therefore, the distance can be measured quickly and accurately in a non-contact manner, and unnecessary images are not reflected on the photographing device.
- the present invention described in claim 24 is the imaging device according to any one of claims 16 to 21, wherein the distance measuring unit is an electromagnetic wave (e.g., longer than a wavelength of infrared light, for example, It is characterized by radar means using a millimeter-wave radar. In addition to being able to measure the distance quickly and accurately by touching, unnecessary images are not reflected on the camera.
- the distance measuring unit is an electromagnetic wave (e.g., longer than a wavelength of infrared light, for example, It is characterized by radar means using a millimeter-wave radar.
- the present invention described in claim 25 is the photographing device according to any one of claims 16 to 21, wherein the distance measuring means is a first photographing means and a photographed image of the second photographing means. It is characterized in that it is a calculating means for calculating the distance to the surface to be photographed, and thus the distance to the surface to be photographed is determined by the image obtained by the first and second photographing means. It is not necessary to provide any special distance measuring means since it can be obtained by calculation from.
- the present invention described in claim 26 is the imaging device according to any one of claims 16 to 25, wherein the rocking means is an electric device provided below the imaging device. Therefore, each of the left and right imaging units is driven quickly and accurately by the electric device.
- a swing unit is provided in both the first and second imaging units. Therefore, the first photographing means and the second photographing means can be arranged at symmetrical positions with respect to an axis perpendicular to the plane to be photographed.
- the present invention described in claim 28 is the imaging device according to any one of claims 16 to 27, wherein the distance measurement by the distance measurement unit and the driving of the swing unit by the swing adjustment unit. Is characterized in that it is performed during video shooting, so that an optimum image can be obtained even when the object is moving.
- the present invention described in claim 29 is the imaging device according to any one of claims 16 to 27, wherein the distance measurement by the distance measurement unit and the driving of the swing unit by the manual adjustment unit. The feature is that it is performed before shooting a video, so if the object does not move, an optimal image can be obtained only by adjusting the CP and focus once before shooting.
- the present invention described in claim 30 is the imaging device according to any one of claims 15 to 29, wherein the imaging unit measures a distance to the object to be measured measured by the distance measurement unit. Since the focus is based on the focus, the standard for focusing the imaging means and the standard for setting the CP are the same, so that image defects due to errors in distance measurement can be prevented. No equipment is required.
