Patent ID: 8511901

Claim:
An image recording apparatus comprising: a recorder configured to record stream data in a recording medium; and a central processing unit (CPU) that: (a) generates third stream data by using a moving image signal recorded at a first frame rate, (b) controls the recorder to record the third stream data in the recording medium, (c) starts to generate second stream data by using a moving image signal recorded at a second frame rate in response to an instruction for instructing a change of a frame rate while the third stream data is generated, (d) controls the recorder to record the second stream data in the recording medium, (e) determines a frame rate of the third stream data, (f) controls the recorder to generate first stream data relating to a determined frame rate of the third stream data from the second stream data based on a predetermined process, and (g) controls the recorder to record the first stream data in the recording medium, wherein the second frame rate is higher than the first frame rate, and wherein the predetermined process includes a process for converting a frame number of the second stream data based on the determined frame rate of the third stream data.
