Image sensing apparatus and method for controlling the same

摘要

The present invention provides an image sensing apparatus including an encoding unit for converting video from an image sensing unit so as to generate stream data, and store the stream data in a buffer unit, a control unit for controlling the encoding unit, in a case where, in a fixed time recording mode for recording for a fixed time in response to an instruction to start recording, a second instruction to start recording is issued before the fixed time has elapsed since a first instruction to start recording was issued, to store in the buffer unit stream data that lasts for the fixed time corresponding to the first instruction to start recording, and stream data that lasts for the fixed time corresponding to the second instruction to start recording, and a recording unit for recording each piece of stream data stored in the buffer unit on a recording medium.

主权项

1. An image sensing apparatus comprising:
an encoding unit configured to convert video from an image sensing unit to generate stream data; a recording unit configured to record the stream data generated by the encoding unit on a recording medium, wherein in a case where, in a fixed time recording mode for recording for a fixed time tc in response to an instruction to start recording, a second instruction to start recording is not issued before the fixed time tc has elapsed since a time t1 when a first instruction to start recording was issued, the recording unit sets an end time of recording to t1+tc, and in a case where the second instruction is issued at a time t2 before the fixed time tc has elapsed since the time t1 when the first instruction was issued, the recording unit extends the end time of recording to t2+tc; a storage unit configured to store the time t1 when the first instruction was issued and the time t2 when the second instruction was issued; and a control unit configured to cut out stream data that lasts for the fixed time tc from the stored time t1 when the first instruction was issued and stream data that lasts for the fixed time tc from the stored time t2 when the second instruction was issued, respectively, from the stream data recorded on the recording medium, and to record the cut-out stream data on the recording medium.
