Abstract

In response to an input of a recording instruction, a recorder is controlled to record on a recording medium moving image data of a predetermined time length before the recording instruction is input among the moving image data temporarily stored in a memory, and in response to that a predetermined condition is determined to be satisfied before the recording instruction is input, the recording unit is controlled not to record on the recording medium the moving image data stored in the memory before the predetermined condition is determined to be satisfied.

Claims

1. A moving image data recording apparatus comprising:

an acquisition unit configured to acquire moving image data;

a recorder configured to record, on a recording medium, moving image data; and

a controller configured to, in response to an input of a recording instruction, perform control to record, on the recording medium, moving image data for a predetermined time length acquired by the acquisition unit before the input of the recording instruction,

wherein, if the moving image data recording apparatus is rotated by a predetermined angle or larger before the input of the recording instruction, the controller is configured to perform control not to record moving image data acquired before the moving image data recording apparatus is rotated by the predetermined angle or larger out of the moving image data for the predetermined time length, and to perform control to record moving image data acquired after the moving image data recording apparatus is rotated by the predetermined angle or larger out of the moving image data for the predetermined time length.

2. The moving image data recording apparatus according to claim 1, further comprising:

a memory configured to temporarily store moving image data of at least the predetermined time length acquired by the acquisition unit,

wherein in response to the input of the recording instruction, the controller performs control to record the moving image data of the predetermined time length temporarily stored in the memory, and

wherein the controller deletes the moving image data temporarily stored, in the memory, before the moving image data recording apparatus is rotated by the predetermined angle or larger.

3. The moving image data recording apparatus according to claim 1, further comprising:

a memory configured to temporarily store moving image data of at least the predetermined time length acquired by the acquisition unit,

wherein in response to the input of the recording instruction, the controller performs control to record the moving image data of the predetermined time length temporarily stored in the memory, and

wherein the controller performs control not to record, on the recording medium, the moving image data which has been temporarily stored, in the memory, before the moving image data recording apparatus is rotated by the predetermined angle or larger, even though the moving image data is temporarily stored in the memory before the input of the recording instruction.

4. The moving image data recording apparatus according to claim 1, further comprising:

a still image data acquisition unit configured to acquire still image data,

wherein the controller performs control to record, on the recording medium, the still image data acquired by the still image data acquisition unit and the moving image data acquired by the acquisition unit in response to the input of the recording instruction.

5. The moving image data recording apparatus according to claim 1, wherein the controller performs control to record a plurality of pieces of the moving image data each corresponding to a different one of a plurality of recording instructions, as one moving image file.

6. The moving image data recording apparatus according to claim 5, wherein the controller performs control to record the plurality of pieces of the moving image data captured at a same day as one moving image file.

7. The moving image data recording apparatus according to claim 5, wherein the controller performs control to record moving image data captured at different days, as different files.

8. The moving image data recording apparatus according to claim 1 further comprising:

an imaging unit,

wherein the acquisition unit acquires moving image data obtained by the imaging unit.

9. The moving image data recording apparatus according to claim 1, further comprising:

an imaging unit; and

a still image acquisition unit configured to, in response to an input of a still image recording instruction, acquire still image data obtained by the imaging unit,

wherein the acquisition unit acquires moving image data obtained by the imaging unit, and

wherein the controller performs control, in response to the input of the still image recording instruction, to record, on the recording medium, the still image data acquired by the still image acquisition unit and the moving image data acquired by the acquisition unit before the input of the still image recording instruction.

10. A method for controlling a moving image data recording apparatus comprising:

acquiring moving image data, performing control, in response to an input of a recording instruction, to record, on a recording medium, moving image data for a predetermined time length acquired before the input of the recording instruction;

wherein if the moving image data recording apparatus is rotated by a predetermined angle or larger before the input of the recording instruction, performing control not to record moving image data acquired before the moving image data recording apparatus is rotated by the predetermined angle or larger out of the moving image data for the predetermined time length, and to perform control to record moving image data acquired after the moving image data recording apparatus is rotated by the predetermined angle or larger out of the moving image data for the predetermined time length.

11. A non-transitory computer-readable storage medium storing a program that causes a computer to execute the method according to claim 10.
