Abstract:
1. A network camera apparatus for transmitting video frames formed in an image sensing unit to a client apparatus, the network camera apparatus comprising: a communication unit configured to communicate with the client apparatus; acquiring means for acquiring a time interval related to the video frames formed in the image sensing unit; determination means for, if the communication unit receives from the client apparatus a request for the video frames, determining a type of the received request; and a control unit configured to, (a) in a case where the determination means determines that the received request is for recording, execute a process for transmitting a video frame formed in the image sensing unit based on the time interval acquired by the acquiring means, (b) in a case where the determination means determines that the received request is for a live display and the transmission of a last video frame formed at a first timing is completed earlier than a second timing which is later than the first timing by the acquired time interval, execute a process for transmitting a video frame, the frame having been formed in the image sensing unit at the second timing, and (c) in a case where the determination means determines that the received request is for the live display and if the transmission of the last video frame is completed between the second timing and a third timing which is later than the second timing by the acquired time interval, execute a process for transmitting a video frame, the video frame having been formed in the image sensing unit at a fourth timing which is later than the second timing and earlier than the third timing.
