Multi-camera system, camera, camera processing method, confirmation device, and confirmation device processing method

An information processing apparatus, comprising:

• a communication interface, and
• processing circuitry configured to receive a predetermined request from a user while a first camera apparatus captures a first video and a second camera apparatus captures a second video;
• and
• in response to the predetermined request,
• transmit, via the communication interface, a first control signal to the first camera apparatus that causes the first camera apparatus to generate a first thumbnail of a frame of the first video, and
• transmit, via the communication interface, a second control signal to the second camera apparatus that causes the second camera apparatus to generate a second thumbnail of a frame of the second video;
• receive the first thumbnail from the first camera apparatus;
• and
• receive the second thumbnail from the second camera apparatus.

A non-transitory computer-readable medium storing instruction which when executed by a computer cause the computer to perform a method of obtaining thumbnails, the method comprising:

• receiving a predetermined request from a user while a first camera apparatus captures a first video and a second camera apparatus captures a second video;
• in response to the predetermined request,
• transmitting to the first camera apparatus a first control signal that causes the first camera apparatus to generate a first thumbnail of a frame of the first video, and
• transmitting to the second camera apparatus a second control signal that causes the second camera apparatus to generate a second thumbnail of a frame of the second video,
• receiving the first thumbnail from the first camera apparatus;
• and
• receiving the second thumbnail from the second camera apparatus.
