Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panoramic photographing device which is constructed so that a camera body can be rotated by a motor to take a panoramic photograph.

[0002]

2. Description of the Related Art Conventionally known camera devices are constructed so that when a panoramic picture is taken, the camera body is rotated at a fixed angle.

[0003]

However, in the above-mentioned conventional example, there is a problem that the following phenomenon occurs when a panoramic photograph is taken by changing the focal length of the taking lens.

A) The seam between the screens is doubled (on the short focus side). b) The joints between the screens are too open, and when connecting them later, there is a gap between them and they do not connect well (long focus side).

An object of the present invention is to provide a panoramic photographing device capable of photographing panoramic photographs without causing the above-mentioned phenomenon and without causing a joint between screens.

[0006]

In the photographing apparatus of the present invention,
By providing a control device that makes the distance between the shooting lens and the moving angle of the camera body a predetermined relationship, the moving angle of the camera body is determined by determining the distance of the shooting lens, and the distance of the shooting lens is determined by determining the moving angle. This makes it possible to take beautiful panoramic photos without duplication or blemishes in the joints.

Release operation. In # 103, the panorama mode switch detecting means 3 determines whether or not the panorama mode switch 2 is ON. If it is OFF, the process returns to # 101, and if it is ON, the zoom position detecting device 10 detects the position of the zoom lens 9 in # 104. And sends it to the calculating means 6. Then # 105
Then, the camera angle detection device 13 detects the camera angle and sends it to the calculation means 6. Next, in # 106, the calculating means 6 calculates the angle at which the camera is moved. In step # 107, the control means 7 drives the motor 12 via the motor drive means 11 to move the camera. In # 108, the camera angle detection device 13 detects the angle of the camera, and in # 109, the calculation means 6 compares the data from the camera angle detection device 13 with the calculation result in # 106. If the movement has not ended, the process returns to # 107 and repeats. If the movement has ended, the power supply is stopped and the process returns to # 101.

In the calculation of # 106, assuming that the focal length f = zoom position and the length of the film screen is 36 mm,
