Abstract

In order to enable a substitute representative image to be properly selected in a case where a representative image representing a plurality of series of related images was deleted, if a deletion or the like of the representative image is performed, whether or not the representative image is associated with an image file which is subsequently read out is discriminated on the basis of attribute information of each image. If it is associated as a result of the discrimination, a system control unit stores the attribute information of the current read-out image file and repeats a processing until an image number is equal to a minimum number or the image file which is not the unrelated image is detected. Even if the representative image is deleted, a representative image is enabled to be selected from the images associated with the deleted representative image.

Claims

1. An image processing apparatus comprising:

a processor coupled to a memory and programmed to function as;

an analyzation unit configured to analyze attribute information of each of a plurality of images stored in the memory;

a deletion unit configured to delete, in the memory, a representative image representing a group which is constructed with the plurality of images, from the group; and

a selection unit configured to select, in the memory, a representative image representing the group in place of the representative image of the group deleted by the deletion unit on the basis of relation between the attribute information of the deleted representative image and the attribute information of each image included in the group other than an image corresponding to the deleted representative image from images included in the group other than the image corresponding to the deleted representative image, in response to the deletion of the representative image by the selection unit.

2. An apparatus according to claim 1, wherein the selection unit selects an image closest to an attribute of the representative image deleted by the deletion unit.

3. An apparatus according to claim 1, wherein when it is analyzed by the analyzation unit that the deleted representative image has a plurality of attributes, the selection unit selects an image having the largest number of attributes which are same as or similar to the attributes of the representative image deleted by the deletion unit.

4. An apparatus according to claim 1, wherein the selection unit selects an image which coincides with all attributes of the representative image deleted by the deletion unit.

5. An apparatus according to claim 3, wherein when a narrow-down setting is already down, the selection unit selects an image having the largest number of attributes which are same as or similar to the attributes narrowed down from the attributes of the representative image deleted by the deletion unit.

6. An apparatus according to claim 1, wherein the deletion unit and the selection unit operate in a mode for sequentially reproducing the representative image of each group.

7. An apparatus according to claim 1, wherein if the image having the attribute of the representative image deleted by the deletion unit does not exist as a result of the analyzation by the analyzation unit, the selection unit selects an image recorded subsequently to the deleted representative image.

8. An apparatus according to claim 1, wherein the plurality of images included in the group are images sequentially photographed by a continuous photographing, a bracket photographing, a panorama photographing, or a 3D image photographing.

9. An image processing method comprising the steps of:

analyzing attribute information of each of a plurality of images;

deleting a representative image representing a group which is constructed with the plurality of images, from the group; and

selecting a representative image representing the group in place of the representative image of the group deleted in the deletion step on the basis of relation between the attribute information of the deleted representative image and the attribute information of each image included in the group other than an image corresponding to the deleted representative image from images included in the group other than the image corresponding to the deleted representative image, in response to the deletion of the representative image.

10. A non-transitory computer-readable storage medium storing a program comprising a program code for causing a computer to execute the image processing method according to claim 9.
