Abstract

A control method of an image pickup apparatus has: an output step of outputting a photographed image to an external image processing apparatus; a transmission step of transmitting a transmission request of parameter information of an image processing to the photographed image which is generated by the external image processing apparatus, to the external image processing apparatus; a receiving step of receiving the parameter information from the external image processing apparatus; a recording step of recording the received parameter information in relation the photographed image; a detection step of detecting an operation in the image pickup apparatus; and a control step of executing a processing for transmitting the transmission request of the parameter information to the external image processing apparatus in the transmission step when the predetermined operation is detected in the detection step.

Claims

1. An image pickup apparatus comprising:

an image pickup unit configured to pick up an image of an object;

an output unit configured to output a photographed image picked up by the image pickup unit to an external image processing apparatus;

a transmission unit configured to transmit a transmission request of parameter information of an image processing to the photographed image which is generated by the external image processing apparatus, to the external image processing apparatus;

a receiving unit configured to receive the parameter information from the external image processing apparatus;

a recording unit configured to record the parameter information received by the receiving unit in relation to the photographed image;

an operation detection unit configured to detect an operation in the image pickup apparatus; and

a control unit configured to control the transmission of the transmission request of the parameter information by the transmission unit,

wherein the control unit controls the transmission unit so as to transmit the transmission request of the parameter information to the external image processing apparatus when the operation detection unit detects the predetermined operation.

2. An apparatus according to claim 1, further comprising:

an obtaining unit configured to obtain information for determining whether or not the photographed image which is output from the output unit is input to the external image processing apparatus from the external image processing apparatus; and

a determination unit configured to determine whether or not the photographed image is input to the external image processing apparatus on the basis of the information obtained by the obtaining unit,

wherein the control unit controls the transmission unit so as to transmit the transmission request of the parameter information to the external image processing apparatus when the determination unit determines that the photographed image is input to the external image processing apparatus.

3. An apparatus according to claim 1, wherein the parameter information is parameter information for adjusting a color and a gradation.

4. An apparatus according to claim 1, wherein the operation in the image pickup apparatus, which is detected by the operation detection unit, is an operation regarding the recording of the photographed image.

5. An apparatus according to claim 1, wherein the operation in the image pickup apparatus, which is detected by the operation detection unit, is an operation regarding the reproduction of the photographed image.

6. An apparatus according to claim 1, wherein the operation in the image pickup apparatus, which is detected by the operation detection unit, is an operation to determine an image angle of the photographed image.

7. An apparatus according to claim 1, wherein the operation in the image pickup apparatus, which is detected by the operation detection unit, is an operation to adjust an amount of light which enters the image pickup unit.

8. An apparatus according to claim 1, further comprising a warning unit configured to warn a user when the parameter information cannot be received by the reception unit after the transmission unit transmits the transmission request of the parameter information to the external image processing apparatus.

9. An apparatus according to claim 1, wherein the receiving unit receives numeric information of the parameter information.

10. An apparatus according to claim 9, wherein the recording unit records the parameter information received by the receiving unit as additional information of the photographed image.

11. An apparatus according to claim 1, wherein the transmission unit transmits the transmission request of ID information to specify the parameter information to the external image processing apparatus, and

wherein the receiving unit receives the ID information from the external image processing apparatus.

12. An apparatus according to claim 11, wherein the recording unit specifies the parameter information from the ID information received by the receiving unit and records the specified parameter information as additional information of the photographed image.

13. An apparatus according to claim 1, further comprising a change detection unit configured to detect a change between photographing state information of a preceding photographed image and a current photographed image,

and wherein when the change detection unit does not detect the change of the photographing state information, the recording unit records the parameter information related to the preceding photographed image as additional information of the current photographed image.

14. An apparatus according to claim 13, wherein the photographing state information is information including one of a state of the photographed object and a state of the operation of the image pickup apparatus.

15. A control method of an image pickup apparatus, comprising:

an output step of outputting a photographed image to an external image processing apparatus;

a transmission step of transmitting a transmission request of parameter information of an image processing to the photographed image which is generated by the external image processing apparatus, to the external image processing apparatus;

a receiving step of receiving the parameter information from the external image processing apparatus;

a recording step of recording the parameter information received in the reception step in relation to the photographed image;

an operation detection step of detecting an operation in the image pickup apparatus; and

a control step of executing a processing for transmitting the transmission request of the parameter information to the external image processing apparatus in the transmission step when the predetermined operation is detected in the operation detection step.

16. A non-transitory computer-readable storage medium storing a program for allowing a computer to execute:

an output step of outputting a photographed image to an external image processing apparatus;

a transmission step of transmitting a transmission request of parameter information of an image processing to the photographed image which is generated by the external image processing apparatus, to the external image processing apparatus;

a receiving step of receiving the parameter information from the external image processing apparatus;

a recording step of recording the parameter information received in the reception step in relation to the photographed image;

an operation detection step of detecting an operation in the image pickup apparatus; and

a control step of executing a processing for transmitting the transmission request of the parameter information to the external image processing apparatus in the transmission step when the predetermined operation is detected in the operation detection step.
