Image data processing apparatus, method, program and recording medium

An image data processing method comprising:

• loading contents data containing moving image data encoded by a first scheme, which is recorded in recording means, and decoding the moving image data;
• obtaining image data, which corresponds to the image to be displayed at a predetermined time, as data of a still image, which is the decoded moving image data;
• creating time information on a time when the still image is shot based on information added to the encoded moving image data;
• and
• encoding the obtained still image data by a second scheme along with the created time information.

A computer-readable program comprising:

• controlling loading contents data containing moving image data encoded by a first scheme, which is recorded in recording means, and decoding the moving image data;
• controlling obtaining image data, which corresponds to the image to be displayed at a predetermined time, as data of a still image, which is the decoded moving image data;
• controlling creating time information on a time when the still image is shot based on information added to the encoded moving image data;
• and
• controlling encoding the obtained still image data by a second scheme along with the created time information.

An image data processing apparatus comprising:

• a recording section recording contents data containing moving image data, which is encoded by a first scheme;
• a moving image decoding section loading the contents data recorded in the recording section and decoding the moving image data;
• a still image encoding section obtaining image data, which corresponds to the image to be displayed at a predetermined time, as data of a still image, which is the moving image data decoded by the moving image decoding section, and encoding the image data by a second scheme;
• and
• a time information creating section creating information on a time when the still image is shot based on information added to the encoded moving image data.
