Abstract

An information processing apparatus obtains image data included in an image file stored in a storage medium of the digital camera and the updated time of the image file stored in the storage medium of the digital camera, and reads out the shooting time of the image data included in the header of the image file stored in the storage medium of the information processing apparatus. The information processing apparatus displays a first view that displays the image data in an order based on the obtained updated time, and a second view that displays the image data included in the image file stored in the storage medium of the information processing apparatus in an order based on the read out shooting time.

Claims

1. An information processing apparatus capable of communicating with an external apparatus, the information processing apparatus comprising:

a first obtaining unit that obtains, from the external apparatus, a plurality of first image data each included in a first image file stored in a storage medium of the external apparatus;

a second obtaining unit that obtains information of the first image files from a management area of the storage medium of the external apparatus;

a first readout unit that reads out a plurality of second image data each included in a second image file stored in a storage medium of the information processing apparatus; and

a second readout unit that reads out an information of the second image data from header of the second image file; and

a output unit capable of outputting a first view that outputs the plurality of first image data obtained by the first obtaining unit from the external apparatus, and a second view that outputs the plurality of second image data read out by the first readout unit from the storage medium of the information processing apparatus;

wherein the output unit outputs the plurality of first image data in an order based on the information of the first image files from the management area of the storage medium of the external apparatus in response to start of outputting the first view, and outputs the plurality of second image data in an order based on the information of the second image files from header of the second image files in response to start of outputting second view.

2. The apparatus according to claim 1, further comprising a switching unit that switches between outputting the first view and outputting the second view in accordance with a user'"'"'s operation.

3. The apparatus according to claim 1,

wherein the second obtaining unit obtains the information of the first image files before the first obtaining unit obtains the plurality of first image data;

and

the first obtaining unit obtains the first image data in an order based on the information of the first image files obtained by the second obtaining unit.

4. The apparatus according to claim 1, further comprising a comparing unit that compares the information of the first image files stored in the storage medium of the external apparatus obtained by the second obtaining unit with information stored in a header of the first image files,

wherein the output unit outputs the first view in an order based on the information stored in a header of the first image files in a case where a result of a comparison performed by the comparing unit indicates that the information of the first image files obtained from the management area of the storage medium of the external apparatus differs from the information stored in the header of the first image files.

5. The apparatus according to claim 1,

wherein the output unit re-outputs the plurality of first image data in an order based not on the information of the first image files obtained from the management area of the storage medium of the external apparatus but rather on information stored in a header of the first image files when the output of the plurality of first image data is updated based on a user'"'"'s operation in the first view.

6. The apparatus according to claim 2,

wherein the output unit re-outputs the plurality of first image data in an order based not on the information of the first image files obtained from the management area of the storage medium of the external apparatus but rather on information stored in a header of the first image files in a case where an instruction has been made to switch from the second view to the first view.

7. The apparatus according to claim 1, wherein the management area is an entry of the storage medium of the external apparatus.

8. The apparatus according claim 1, wherein the image processing apparatus and the external apparatus are connected by wired communication.

9. The apparatus according to claim 1, wherein the image processing apparatus and the external apparatus are connected via USB (Universal Serial Bus) cable.

10. The apparatus according to claim 1, wherein the image processing apparatus and the external apparatus are connected by wireless communication.

11. The apparatus according to claim 1, wherein the image processing apparatus and the external apparatus are connected in accordance with IEEE802.11.

12. The apparatus according to claim 1, wherein communication between the image processing apparatus and the external apparatus is performed in accordance with PTP (Picture Transfer Protocol).

13. The apparatus according to claim 1, wherein the management area is an area other than an area where the image file managed by a file system is recorded.

14. The apparatus according to claim 1, wherein the second readout unit that reads out the information of the second image data from Exif area, wherein the Exif area is an area existing within the header of the second image file.

15. The apparatus according to claim 1, wherein information of the first image files recorded in the management area includes at least one of a name of the first image file, shooting time, update time, and file size.

16. The apparatus according to claim 1, wherein the external apparatus is an image capturing device.

17. The apparatus according to claim 1, wherein the first image data is recorded in a header of the first image file, and the second image data is recorded in a header of the second image file.

18. A control method for an information processing apparatus capable of communicating with an external apparatus, the method comprising:

a first obtaining step of obtaining, from the external apparatus, a plurality of first image data each included in a first image file stored in a storage medium of the external apparatus;

a second obtaining step of obtaining information of the first image files from a management area of the storage medium of the external apparatus;

a first reading step of reading out a plurality of second image data each included in a second image file stored in a storage medium of the information processing apparatus; and

a second reading step of reading out an information of the second image data from header of the second image file; and

a output step of outputting a first view that output s the plurality of first image data obtained in the first obtaining step from the external apparatus, and a second view that output s the plurality of second image data read out in the first reading step from the storage medium of the information processing apparatus;

wherein the plurality of first image data are outputted in an order based on the information of the first image files from the management area of the storage medium of the external apparatus in response to start of outputting the first view in the output step, and the plurality of second image data are outputted in an order based on the information of the second image files from header of the second image files in response to start of outputting the second view in the output step.

19. A non-transitory storage medium in which is stored a computer-readable program for causing a computer to execute the control method of claim 18.
