Abstract:
1. An image data processing device, comprising: a memory portion for storing image data; and a control portion for extracting a part or the whole of the image data as a partial area, determining a reproduction order for continuously reproducing one or more of the extracted partial areas in accordance with an instruction from a user, and storing the determined reproduction order as an image data index in the memory portion, wherein when the image data is stored in the memory portion, the control portion generates an association information storage area which is an area for storing association information that indicates association between the image data and the image data index in the memory portion such that the association information storage area is associated with title information on the image data, when the image data was used to create the image data index, the control portion stores identification information for identifying the image data index created using the image data in the association information storage area previously generated for the image data, and when an instruction to delete the image data is detected, the control portion references the association information storage area associated with the tile information on the image data, reads out the identification information stored in the association information storage area, discriminates the image data index created using the image data based on the identification information, and updates the discriminated image data index.
