Multi-camera system, camera, processing method of camera, confirmation apparatus, and processing method of confirmation apparatus for capturing moving images

A system, comprising:

• a first camera apparatus;
• a second camera apparatus;
• and
• an information processing apparatus, including
• a communication interface, and
• processing circuitry configured to:
• transmit a start instruction to the first camera apparatus and the second camera apparatus, the start instruction causing the first camera apparatus to start incrementing a first counter and the second camera apparatus to start incrementing a second counter for a video recording time period;
• receive, from the first camera apparatus, a first recording-start frame identifier that indicates a value of the first counter when recording of a first video by the first camera apparatus starts within the video recording time period;
• receive, from the first camera apparatus, a second recording-end frame identifier that indicates the value of the first counter when recording of the first video by the first camera apparatus stops within the video recording time period;
• receive, from the second camera apparatus, a first recording-start frame identifier that identifies a value of the second counter when recording of a second video by the second camera apparatus starts within the video recording time period;
• and
• receive, from the second camera apparatus, a second recording-end frame identifier that identifies the value of the second counter when recording of the second video by the second camera apparatus stops within the video recording time period, wherein
• the first video is associated with frame identifiers that indicate the values of the first of the first camera apparatus during the recording of the first video, and
• the second video is associated with frame identifiers that indicate the values of the second counter by the second camera apparatus during the recording to the second video.

A non-transitory computer-readable medium storing instructions which when executed by a computer cause the computer to perform a method for receiving recording-start frame and recording-end frame identifiers, the method comprising:

• transmitting a start instruction to a first camera apparatus and a second camera apparatus, the start instruction causing the first camera apparatus to start incrementing a first counter and the second camera apparatus to start incrementing a second counter for a video recording time period;
• receiving, from the first camera apparatus, a first recording-start frame identifier that indicates a value of the first counter when recording of a first video by the first camera apparatus starts within the video recording time period;
• receiving, from the first camera apparatus, a second recording-end frame identifier that indicates the value of the first counter when recording of the first video by the first camera apparatus stops within the video recording time period;
• receiving, from the second camera apparatus, a first recording-start frame identifier that identifies a value of the second counter when recording of a second video by the second camera apparatus starts within the video recording time period;
• and
• receiving, from the second camera apparatus, a second recording-end frame identifier that identifies the value of the second counter when recording of the second video by the second camera apparatus stops within the video recording time period, wherein
• the first video is associated with frame identifiers that indicate the values of the first of the first camera apparatus during the recording of the first video, and
• the second video is associated with frame identifiers that indicate the values of the second counter by the second camera apparatus during the recording to the second video.
