Image processing apparatus capable of displaying document thumbnail image, image processing apparatus control method, and storage medium
An image processing apparatus includes a memory, and a processor in communication with the memory, the processor configured to control a storage unit configured to associate and store a document and a thumbnail image of a top page of the document, a deletion unit configured to delete a page designated from among pages of the document stored in the storage unit, and a generation unit configured to, in a case where a page to be deleted by the deletion unit is a top page of the document, generate a thumbnail image based on the top page of the document after deletion.
1. An image processing apparatus comprising:
a document storage unit configured to store documents and thumbnail images of the documents;
a memory storing instructions; and
one processor which executes the instructions and causes an image processing apparatus to function as:
a receiving unit configured to receive a deletion instruction for deleting a document from the document storage unit
a deleting unit configured to delete the document from the document storage unit in accordance with the deletion instruction received by the receiving unit;
a determining unit configured to determine whether a thumbnail image of the document to be deleted is associated with a document that is different from the document to be deleted and is stored in the document storage unit; and
a control unit configured not to delete the thumbnail image in a case where it is determined as a result of determination by the determining unit that the thumbnail image is associated with the document that is different from the document to be deleted and configured to delete the thumbnail image in a case where it is determined as the result of the determination by the determining unit that the thumbnail image is not associated with the document that is different from the document to be deleted.
2. The apparatus according to claim 1 , further comprising an operation unit configured to display the thumbnail images on an operation screen and then receives the deletion instruction for a document corresponding to a thumbnail image selected via the operation screen.
3. The apparatus according to claim 2 , further comprising a printer configured to print an image based on a document corresponding to a thumbnail image selected via the operation screen.
4. The apparatus according to claim 1 , further comprising a scanner configured to read an original to generate image data,
wherein the processor is configured to store the image data as a document in the document storage unit.
5. The apparatus according to claim 1 ,
wherein the processor is configured to rasterize print data, which is received from a host computer, into image data and then store the image data as a document in the document storage unit.
6. The apparatus according to claim 1 , wherein each of the thumbnail images is generated from a corresponding top page of the documents.
7. A control method for an image processing apparatus including a document storage unit configured to store documents and thumbnail images of the documents, the control method comprising:
receiving a deletion instruction for deleting a document from the document storage unit;
deleting the document from the document storage unit in accordance with the deletion instruction;
determining whether a thumbnail image of the document to be deleted is associated with a document that is different from the document to be deleted and is stored in the document storage unit; and
controlling not to delete the thumbnail image in a case where it is determined that the thumbnail image is associated with the document that is different from the document to be deleted and controlling to delete the thumbnail image in a case where it is determined that the thumbnail image is not associated with the document that is different from the document to be deleted.
8. A non-transitory computer-readable storage medium storing a program for causing a computer to execute the control method according to claim 7 .
