The information processing apparatus includes a communication interface, and processing circuitry that receives a predetermined request from a user while the first camera apparatus captures a first video and the second camera apparatus captures a second video. The processing circuitry, in response to the predetermined request, transmits 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 transmits 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. The processing circuitry receives the first thumbnail from the first camera apparatus and the second thumbnail from the second camera apparatus. ## Claims ### Claim 1 A multi-camera system, comprising: a first camera apparatus; a second camera apparatus; and an information processing apparatus including a communication interface, and processing circuitry configured to receive a predetermined request from a user while the first camera apparatus captures a first video and the second camera apparatus captures a second video; 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. ### Claim 2 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. ### Claim 3 (depends on 2) The information processing apparatus according to claim 2, wherein a field of view of the first camera apparatus that captures the first video is different from a field of view of the second camera apparatus that captures the second video. ### Claim 4 (depends on 2) The information processing apparatus according to claim 2, wherein the processing circuitry is configured to output a user interface that includes the first and second thumbnails that are associated with the predetermined request in a single screen for display to the user. ### Claim 5 (depends on 2) The information processing apparatus according to claim 2, wherein the single screen indicates a timing of the first video that is associated with the first thumbnail and a timing of the second video that is associated with the second thumbnail. ### Claim 6 (depends on 2) The information processing apparatus according to claim 2, wherein the processing circuitry is configured to receive a start recording request from the user; and in response to the start recording request, transmit to the first camera apparatus a third control signal that causes the first camera apparatus to start capturing the first video, and transmit to the second camera apparatus a fourth control signal that causes the second camera apparatus to start capturing the second video. ### Claim 7 (depends on 6) The information processing apparatus according to claim 6, wherein the processing circuitry is configured to receive a stop recording request from the user; and in response to the start recording request, transmit to the first camera apparatus a fifth control signal that causes the first camera apparatus to end capturing of the first video, and transmit to the second camera apparatus a sixth control signal that causes the second camera apparatus to end capturing of the second video. ### Claim 8 (depends on 2) The information processing apparatus according to claim 2, wherein the processing circuitry is configured to output one or a combination of a remaining storage capacity, battery level, heat level, and communication status of each of the first and second camera apparatuses in a single screen for display to the user. ### Claim 9 (depends on 2) The information processing apparatus according to claim 2, wherein the first camera apparatus captures the first video and the second camera apparatus captures the second video of the same object from different angles. ### Claim 10 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. ### Claim 11 (depends on 10) The non-transitory computer-readable medium according to claim 10, wherein a field of view of the first camera apparatus that captures the first video is different from a field of view of the second camera apparatus that captures the second video. ### Claim 12 (depends on 10) The non-transitory computer-readable medium according to claim 10, further comprising: outputting a user interface that includes the first and second thumbnails that are associated with the predetermined request in a single screen for display to the user. ### Claim 13 (depends on 10) The non-transitory computer-readable medium according to claim 10, wherein the single screen indicates a time within the first video that is associated with the first thumbnail and a time within the second video that is associated with the second thumbnail. ### Claim 14 (depends on 10) The non-transitory computer-readable medium according to claim 10, further comprising: receiving a start recording request from the user; and in response to the start recording request, transmitting to the first camera apparatus a third control signal that causes the first camera apparatus to start capturing the first video, and transmitting to the second camera apparatus a fourth control signal that causes the second camera apparatus to start capturing the second video. ### Claim 15 (depends on 14) The non-transitory computer-readable medium according to claim 14, further comprising: receiving a stop recording request from the user; and in response to the start recording request, transmitting to the first camera apparatus a fifth control signal that causes the first camera apparatus to end capturing of the first video, and transmitting to the second camera apparatus a sixth control signal that causes the second camera apparatus to end capturing of the second video. ### Claim 16 (depends on 10) The non-transitory computer-readable medium according to claim 10, further comprising: outputting one or a combination of a remaining storage capacity, battery level, heat level, and communication status of each of the first and second camera apparatuses in a single screen for display to the user. ### Claim 17 (depends on 10) The non-transitory computer-readable medium according to claim 10, wherein the first camera apparatus captures the first video and the second camera apparatus captures the second video of the same object from different angles.
