Problems solved by technology

In such a case, it becomes impossible to synchronize the shooting operation of the camera, so whether the synchronization is unreliable or not, there is a problem in the reliability of the synchronization
In addition, if you only want to improve the reliability of synchronization, the accuracy of synchronization may decrease

Embodiment Construction

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. figure 1 It is a plan view showing the camera system according to this embodiment. This camera system is composed of a master camera 1 and a slave camera 2 arranged in an imaging area PA. These two cameras 1 and 2 are arranged to face each other during shooting, and it is intended to capture moving images of a subject 30 (for example, a golfer performing a golf swing) existing therebetween from left and right directions.

[0020] figure 2 It is a block diagram showing a schematic configuration of both cameras 1 and 2 , and in the present embodiment, the master camera 1 and the slave camera 2 have the same configuration. These cameras 1 and 2 include a control unit 3 connected to each unit via a bus 20 , and the control unit 3 is a single-chip microcomputer that controls each unit of the cameras 1 and 2 . The imaging unit 4 is composed of a CMOS image sensor, and is ...

Abstract

The invention provides an imaging device and an imaging control method. The camera of the present invention is provided with an imaging element, and detects light blinking at the reference timing based on the timing of brightness change of the captured image obtained by imaging the light periodically blinking at the reference timing by the imaging element. light flicker timing, and based on the detected flicker timing, the exposure timing at which the imaging element performs exposure is adjusted, thereby synchronizing the shooting operations of the plurality of cameras.

Description

technical field [0001] The present invention relates to a camera having a synchronous shooting function, a recording medium on which a shooting control program for the camera is recorded, and a shooting control method. Background technique [0002] Conventionally, there is a moving image shooting / playback method in which a plurality of cameras are used to capture moving images of the same subject from different directions, and the captured moving images are reproduced synchronously. This moving image capture / reproduction method is used, for example, in golf swing form (form) inspection, etc., by synchronously reproducing a plurality of top-view images (two-dimensional images) captured from different directions, which can be stereoscopically (three-dimensionally) ) to grasp the reproduced image. Therefore, by observing the reproduced image, the swing motion at the same point in time can be grasped three-dimensionally, and the three-dimensional evaluation of the subject's mot...
