US 8,302,142 B2 · Network camera apparatus and distributing method of video frames

Abstract

When a request for a transmitting method of video frames of the client apparatus is received in a communicating unit to communicate with said client apparatus, whether the received request for the transmitting method of the video frames is a request for the transmitting method of the video frames for recording or a request for the transmitting method of the video frames for a live display is discriminated. If the received request for the transmitting method of the video frames is the request for the transmitting method of the video frames for recording, each of the video frames formed in an image sensing unit is temporarily stored in a memory and each of the stored video frames is transmitted. If the received request for the transmitting method of the video frames is the request for the transmitting method of the video frames for the live display, a process for transmitting the latest frame among the video frames formed in the image sensing unit is repetitively executed.

Dependent claims

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;
determining means for determining a type of a video frame request from the client apparatus;
and
a control unit configured to (a) in a case where the determining means determines that the video frame request is for a live display and the transmission of a last video frame formed at a first timing is not completed by a second timing later than the first timing by the time interval, control transmitting of a video frame such that a video frame formed at the second timing is not transmitted to the client apparatus and (b) in a case where the determining means determines that the video frame request is for recording and the transmission of the last video frame formed at the first timing is not completed by the second timing, memorize in a memory the video frame formed at the second timing such that the video frame formed at the second timing can be transmitted to the client apparatus at a timing later than a transmission timing corresponding to the second timing.

A video frame transmitting method of a network camera apparatus for transmitting video frames formed in an image sensing unit to a client apparatus, the method comprising:

(a) acquiring a time interval related to the video frames formed in the image sensing unit;
(b) determining a type of a video frame request from the client apparatus;
(c) in a case where it is determined that the video frame request is for live display and the transmission of a last video frame formed at a first timing is not completed by a second timing later than the first timing by the time interval, controlling transmitting of a video frame such that a video frame formed at the second timing is not transmitted to the client apparatus;
and (d) in a case where it is determined that the video frame request is for recording and the transmission of the last video frame formed at the first timing is not completed by the second timing, memorizing in a memory the video flame formed at the second timing such that the video flame formed at the second timing can be transmitted to the client apparatus at a timing later than a transmission timing corresponding to the second timing.
