Abstract

A communication apparatus includes a communication unit that requests image data from an external apparatus and receives image data from an external apparatus in response to the request, a display control unit that displays the received image data on a display unit, and a receiving unit that receives an instruction for selecting displayed image data. The communication unit further requests, from the external apparatus, metadata of selected image data and receives the metadata without receiving the image data. The metadata is recorded in a header area of a file containing the image data stored in the external apparatus.

Claims

1. A communication apparatus comprising:

a communication unit configured to request image data from an external apparatus and to receive image data from the external apparatus in response to the request;

a display control unit configured to display the image data on a display unit; and

a receiving unit configured to receive an instruction for selecting image data displayed by the display control unit,

wherein the communication unit further requests, from the external apparatus, metadata of the selected image data and receives the metadata without receiving the image data, and

wherein the metadata is recorded in a header area of a file containing the image data stored in the external apparatus.

2. The communication apparatus according to claim 1, further comprising a touch panel disposed on the display unit,

wherein, in a case where an operation on the touch panel corresponding to a position where the image data is displayed satisfies a predetermined condition, the receiving unit determines that image data displayed at a position that received the operation on the touch panel has been selected.

3. The communication apparatus according to claim 2, wherein the predetermined condition includes a condition that a predetermined time period has elapsed since the touch operation on the touch panel has been started.

4. The communication apparatus according to claim 1, wherein the image data is a thumbnail of a file containing the image data.

5. The communication apparatus according to claim 1, wherein the image data is a thumbnail recorded in a header area of a file containing the image data.

6. The communication apparatus according to claim 1, wherein the communication unit receives metadata without requesting it.

7. The communication apparatus according to claim 1, wherein received metadata is retained until communication with the external apparatus is disconnected.

8. The communication apparatus according to claim 7, wherein the communication unit receives the metadata that is retained without requesting it.

9. The communication apparatus according to claim 1, wherein the metadata includes EXIF data.

10. A communication apparatus comprising:

a receiving unit configured to receive an instruction; and

a communication unit configured to, upon receipt of the instruction, request, from an external apparatus, EXIF data recorded in a header area of an image file stored in the external apparatus, and to receive the EXIF data transmitted from the external apparatus in response to the request,

wherein the communication unit receives the EXIF data without receiving image data of the image file.

11. The communication apparatus according to claim 10, wherein the communication unit does not request the EXIF data which is already received.

12. The communication apparatus according to claim 10, wherein received EXIF data is retained until communication with the external apparatus is disconnected.

13. The communication apparatus according to claim 12, wherein the communication unit does not request the EXIF data which is already retained.

14. The communication apparatus according to claim 10, wherein the receiving unit is controlled by first computer executable instructions,

wherein the communication unit is controlled by computer executable instructions different than the first computer executable instructions, and

wherein second computer executable instructions are called from the first computer executable instructions upon receipt of the instruction.

15. A communication apparatus comprising:

a communication unit configured to communicate with an external apparatus;

a recording unit configured to record computer executable instructions for controlling the communication unit to request, from the external apparatus, EXIF data recorded in a header area an image file stored in the external apparatus, and receive the EXIF data transmitted from the external apparatus in response to the request; and

a control unit configured to execute the computer executable instructions in response to an instruction from an application loaded into the communication apparatus,

wherein, the computer executable instructions cause the control unit to control the communication unit to receive the EXIF data transmitted from the external apparatus in response to the request, without receiving image data of the image file.

16. The communication apparatus according to claim 15, wherein, the computer executable instructions causes the control unit to control the communication unit not to request the EXIF data which is already received.

17. The communication apparatus according to claim 15, wherein the received EXIF data is retained until communication with the external apparatus is disconnected.

18. The communication apparatus according to claim 17, wherein, the computer executable instructions cause the control unit to control the communication unit not to request the EXIF data which is already retained.

19. A method for controlling a communication apparatus, the method comprising:

requesting image data from an external apparatus;

receiving image data transmitted from the external apparatus;

displaying the received image data on a display unit;

receiving an instruction for selecting image data displayed on the display unit;

requesting, from the external apparatus, metadata of the selected image data; and

receiving the metadata without receiving the image data,

wherein the metadata is recorded in a header area of a file containing the image data stored in the external apparatus.

20. A non-transitory computer-readable storage medium storing computer readable instructions for causing a computer to execute a method for controlling a communication apparatus, the method comprising:

requesting image data from an external apparatus;

receiving image data transmitted from the external apparatus;

displaying the received image data on a display unit;

receiving an instruction for selecting image data displayed on the display unit;

requesting, from the external apparatus, metadata of the selected image data; and

receiving the metadata without receiving the image data,

wherein the metadata is recorded in a header area of a file containing the image data stored in the external apparatus.
