Abstract

Whether or not to execute position information acquisition processing is set. Whether or not position information can be acquired is determined. Additional information to be added to input image data is set according to the setting state and determination result. The set additional information is added to the image data.

Claims

1. An information processing apparatus which inputs image data, adds additional information to the input image data, and outputs the image data, comprising:

input means for inputting image data;

acquisition means for acquiring position information indicating a geographical position of said information processing apparatus;

setting means for setting whether or not to execute position information acquisition processing by said acquisition means;

determination means for determining whether or not to acquire position information by said acquisition means;

additional information setting means for setting additional information to be added to the image data input by said input means in accordance with a setting state by said setting means, and the determination result of said determination means; and

addition means for adding the additional information set by said additional information setting means to the image data.

2. The apparatus according to claim 1, further comprising signing means for executing signing processing to the image data to which the additional information is added by said addition means.

3. The apparatus according to claim 1, wherein when said setting means sets that the position information acquisition processing is not executed, said additional information setting means sets information that advises accordingly as the additional information.

4. The apparatus according to claim 1, wherein when said determination means determines that the position information cannot be acquired, the additional information setting means sets information that advises accordingly as the additional information.

5. The apparatus according to claim 1, wherein when said setting means sets that the position information acquisition processing is executed, and said determination means determines that the position information can be acquired, said additional information setting means sets the position information acquired by said acquisition means as the additional information.

6. The apparatus according to claim 1, further comprising:

first time acquisition means for acquiring a first time at which said input means inputs the image data; and

measurement means for measuring a time period elapsed from the first time,

wherein said additional information setting means sets the additional information to be added to the image data input by said input means in accordance with the setting sate by said setting means, the determination result of said determination means, and a measurement result by said measurement means.

7. The apparatus according to claim 6, further comprising second time acquisition means for acquiring a second time at which said acquisition means acquires the position information,

wherein when said determination means determines that the position information can be acquired, said measurement means calculates a difference between the first time and the second time, and outputs the calculated value as a measurement result.

8. The apparatus according to claim 6, further comprising second time acquisition means for acquiring a second time after the determination processing by said determination means,

wherein when said determination means determines that the position information cannot be acquired, said measurement means calculates a difference between the first time and the second time, and outputs the calculated value as a measurement result.

9. The apparatus according to claim 1, wherein when said determination means determines that the position information cannot be acquired, said acquisition means repetitively executes reception of the position information.

10. The apparatus according to claim 2, further comprising:

first time acquisition means for acquiring a first time at which said input means inputs the image data; and

second time acquisition means for acquiring a second time at which said acquisition means acquires the position information,

wherein said additional information setting means sets, as the additional information, the position information acquired by said acquisition means, and time information according to the first time and the second time.

11. An information processing apparatus for verifying reliability of the position information in an information processing apparatus according to claim 10, comprising:

input means for inputting the image data added with the additional information;

determination means for determining whether or not signature data is added to the image data;

verification means for executing verification processing of the signature data;

calculation means for calculating a difference between the first time and the second time using time information included in the additional information;

reliability determination means for determining reliability of the position information in accordance with a determination result of said determination means, a verification result of said verification means, and a calculation result of said calculation means; and

display means for displaying a determination result of said reliability determination means.

12. A method of controlling an information processing apparatus, which inputs image data, adds additional information to the input image data, and outputs the image data, comprising:

an input step of inputting image data;

an acquisition step of acquiring position information indicating a geographical position of the information processing apparatus;

a setting step of setting whether or not position information acquisition processing is executed in the acquisition step;

a determination step of determining whether or not position information can be acquired in the acquisition step;

an additional information setting step of setting additional information to be added to the image data input in the input step in accordance with a setting state in the setting step, and the determination result in the determination step; and

an addition step of adding the additional information set in the additional information setting step to the image data.

13. A computer readable storage medium for storing a program for making a computer execute control of an information processing apparatus, which inputs image data, adds additional information to the input image data, and outputs the image data, said program making the computer execute:

an input step of inputting image data;

an acquisition step of acquiring position information indicating a geographical position of the information processing apparatus;

a setting step of setting whether or not position information acquisition processing is executed in the acquisition step;

a determination step of determining whether or not position information can be acquired in the acquisition step;

an additional information setting step of setting additional information to be added to the image data input in the input step in accordance with a setting state in the setting step, and the determination result in the determination step; and

an addition step of adding the additional information set in the additional information setting step to the image data.
