Abstract

There is provided an imaging apparatus that continuously reproduces, if first moving image data is acquired by imaging in a first imaging mode for capturing a moving image for a predetermined period of time, and then automatically stopping the capturing of the moving image, second moving image data captured before the capturing of the moving image related to the first moving image data and acquired by the imaging in the first imaging mode and the first moving image data.

Claims

1. An imaging apparatus comprising:

an imaging unit configured to execute imaging in a first imaging mode for capturing a moving image for a predetermined period of time and then automatically stopping the capturing of the moving image, and a second imaging mode for capturing the moving image for a period longer than the predetermined period of time; and

a reproduction unit configured to automatically reproduce, after imaging executed by the imaging unit, moving image data acquired by the imaging,

wherein, if first moving image data is acquired by the imaging in the first imaging mode, the reproduction unit continuously reproduces second moving image data captured before the capturing of the moving image related to the first moving image data and acquired by the imaging in the first imaging mode, and the first moving image data, and

wherein the capturing of the second moving image data is executed for a predetermined period of time and then automatically stops in the same manner as the capturing of the first moving image data.

2. The imaging apparatus according to claim 1, wherein the reproduction unit reproduces, among the moving image data captured before the capturing of the moving image related to the first moving image data and acquired by the imaging in the first imaging mode, moving image data having a latest image capturing date as the second moving image data.

3. The imaging apparatus according to claim 1, wherein the reproduction unit does not reproduce any moving image data acquired by the imaging in the second imaging mode as the second moving image data.

4. The imaging apparatus according to claim 1, wherein the reproduction unit reproduces a part of moving image data containing a last frame as the second moving image data.

5. The imaging apparatus according to claim 1, further comprising a notification unit configured to give, if the reproduction unit continuously reproduces the second moving image data and the first moving image data, a notification to identify which of the first moving image data and the second moving image data currently reproduced moving image data is.

6. The imaging apparatus according to claim 1, further comprising a first setting unit configured to set whether to start reproduction of the second moving image data before reproduction of the first moving image data is started.

7. The imaging apparatus according to claim 1, further comprising a second setting unit configured to set time of reproducing the second moving image data before reproduction of the first moving image data is started.

8. The imaging apparatus according to claim 1, further comprising a cache unit configured to cache moving image data used as the second moving image data,

wherein the reproduction unit reproduces the moving image data cached by the cache unit as the second moving image data.

9. The imaging apparatus according to claim 8, wherein the cache unit starts, in response to a change of the imaging apparatus to the first imaging mode, caching the moving image data to be used as the second moving image data.

11. A non-transitory computer-readable recording medium recording a program for causing a computer to function as the apparatus of claim 1.

10. A method for controlling an imaging apparatus, comprising:

executing imaging in a first mode for capturing a moving image for a predetermined period of time and then automatically stopping the capturing of the moving image and a second imaging mode for capturing the moving image for a period longer than the predetermined period of time; and

automatically reproducing, after the imaging, moving image data acquired by the imaging,

wherein, if first moving image data is acquired by the imaging in the first imaging mode, second moving image data captured before capturing of the moving image related to the first moving image data and acquired by the imaging in the first imaging mode, and the first moving image data are continuously reproduced, and

wherein the capturing of the second moving image data is executed for a predetermined period of time and then automatically stops in the same manner as the capturing of the first moving image data.
