Abstract

An image processing apparatus includes an extraction unit configured to extract a feature amount from information recorded on a recording medium, an acquisition unit configured to acquire an identification image identifying an operator of the recording apparatus, a storage unit configured to store the feature amount and the identification image, wherein the identification image is associated with the feature amount, a search unit configured to compare a feature amount extracted from a predetermined medium by the extraction unit with the feature amount stored in the storage unit, wherein, based on a result of the comparison, the identification image associated with the stored feature amount is associated with the predetermined medium, and an output unit configured to output the identification image associated with the predetermined medium.

Claims

1. An image processing apparatus, the image processing apparatus comprising:

an extraction unit configured to extract a feature amount from information recorded on a recording medium;

an acquisition unit configured to acquire an identification image identifying an operator of the image processing apparatus;

a storage unit configured to store the feature amount and the identification image, wherein the identification image is associated with the feature amount;

a search unit configured to compare a feature amount extracted from a predetermined medium by the extraction unit with the feature amount stored in the storage unit, wherein, based on a result of the comparison, the identification image associated with the feature amount stored in the storage unit is associated with the predetermined medium; and

an output unit configured to output the identification image associated with the predetermined medium.

2. The image processing apparatus according to claim 1, wherein the feature amount is information related to the information recorded on the recording medium.

3. The image processing apparatus according to claim 1, wherein the acquisition unit includes an imaging unit, wherein the imaging unit captures an image of the operator in response to a signal from the image processing apparatus.

4. The image processing apparatus according to claim 3, wherein the image processing apparatus includes a face detection unit,

wherein the face detection unit detects a face from the image captured by the imaging unit, and

wherein the acquisition unit sets the captured image in which the face is detected as the identification image.

5. The image processing apparatus according to claim 1, wherein the identification image includes information about a date and time that relevant recorded information was used for recording.

6. An image processing apparatus, the image processing apparatus comprising:

a reading unit configured to read recorded information;

a recording unit configured to record the read recorded information on a recording medium;

a reception unit configured to receive an identification image identifying an operator of the image processing apparatus;

an extraction unit configured to extract a feature amount from the recorded information;

a storage unit configured to store the feature amount and identification image, wherein the identification image is associated with the feature amount;

a search unit configured to compare a feature amount extracted from a predetermined medium by the extraction unit with the feature amount of the recorded information, wherein, based on a result of the comparison, the identification image associated with the feature amount of the recorded information is associated with the predetermined medium; and

an output unit configured to output the identification image associated with the predetermined medium.

7. A method for processing images, the method comprising:

extracting a feature amount from recorded information recorded on a recording medium;

acquiring an identification image identifying an operator of an image processing apparatus;

storing the feature amount and identification information, wherein the identification image is associated with the feature amount;

comparing a feature amount extracted from a predetermined medium with the stored feature amount, wherein based on a result of the comparing, associating the identification image associated with the stored feature amount with the predetermined medium; and

outputting the identification image associated with the predetermined medium.

8. A program stored on a computer readable storage medium, the program enabling a computer to execute the method of claim 7.
