Abstract

A communication device includes an image pickup unit, a connection unit connected to an external device, a transmission unit including a first function for transmitting an image data recorded in a recording medium to the external device, and a second function for successively transmitting an image data captured by the image pickup unit to the external device, and an output unit configured to output image data, as a candidate of image data to be transmitted by the first function, chosen from among the recorded image data, based on information about a subject captured by the image pickup unit and information about the external device, in a case where an instruction for executing the first function is received while the transmission unit is executing the second function.

Claims

1. A communication device comprising:

an image pickup unit;

a recording unit configured to record image data captured by the image pickup unit to a recording medium;

a connection unit connected to an external device;

a transmission unit including a first function for transmitting the recorded image data to the external device, and a second function for successively transmitting the image data captured by the image pickup unit to the external device; and

an output unit configured to output image data, as a candidate of image data to be transmitted by the first function, chosen from among the recorded image data, based on information about a subject captured by the image pickup unit and information about the external device, in a case where an instruction for executing the first function is received while the transmission unit is executing the second function.

2. The communication device according to claim 1,

wherein the recording unit records, to the recording medium, information for distinguishing image data having been transmitted the second function from other image data, and

the output unit outputs, as a candidate of image data to be transmitted by the first function, image data chosen from among the recorded image data based on information about the subject captured by the image pickup unit, information about the external device, and information held by a holding unit.

3. The communication device according to claim 2,

wherein the output unit outputs, as a candidate of image data to be transmitted by the first function, image data not having been transmitted by the second function chosen from among the recorded image data.

4. The communication device according to claim 1, further comprising:

an analysis unit configured to analyze image data successively obtained by being captured by the image pickup unit, thus successively generating information about the subject;

a holding unit configured to successively hold information about the subject generated by the analysis unit; and

an output unit configured to output image data, as a candidate of image data to be transmitted by the first function, chosen from among the recorded image data, based on information about the subject held by the holding unit from a certain period of time before the instruction is received to when the instruction is received and information about the external device, in a case where an instruction for executing the first function is received while the transmission unit is executing the second function.

5. The communication device according to claim 4,

wherein when the first function is started, analysis processing performed by the analysis unit is stopped.

6. The communication device according to claim 5,

wherein when analysis processing performed by the analysis unit is stopped, already accumulated analysis information is invalidated.

7. A control method of a communication device comprising:

an image pickup step;

a recording step for recording image data captured in the image pickup step to a recording medium;

a connection step for connecting to an external device;

a transmission step including a first function for transmitting the recorded image data to the external device, and a second function for successively transmitting the image data captured in the image pickup step to the external device; and

an output step for outputting image data, as a candidate of image data to be transmitted by the first function, chosen from among the recorded image data, based on information about a subject captured in the image pickup step and information about the external device, in a case where an instruction for executing the first function is received while the second function is executed in the transmission step.

8. The control method according to claim 7,

wherein the recording step records, to the recording medium, information for distinguishing image data having been transmitted the second function from other image data, and

the output step outputs, as a candidate of image data to be transmitted by the first function, image data chosen from among the recorded image data based on information about the subject captured by the image pickup step, information about the external device, and information held by a holding step.

9. The control method according to claim 8,

wherein the output step outputs, as a candidate of image data to be transmitted by the first function, image data not having been transmitted by the second function chosen from among the recorded image data.

10. The control method according to claim 7, further comprising:

an analysis step for analyzing image data successively obtained by being captured by the image pickup step, thus successively generating information about the subject;

a holding step for successively holding information about the subject generated by the analysis step; and

an output step for outputting image data, as a candidate of image data to be transmitted by the first function, chosen from among the recorded image data, based on information about the subject held by the holding step from a certain period of time before the instruction is received to when the instruction is received and information about the external device, in a case where an instruction for executing the first function is received while the transmission step is executing the second function.

11. The control method according to claim 10,

wherein when the first function is started, analysis processing performed by the analysis step is stopped.

12. The control method according to claim 11,

wherein when analysis processing performed by the analysis step is stopped, already accumulated analysis information is invalidated.
