Patent ID: 8566700

Claim:
An information processor which displays a thumbnail image of a document, the information processor comprising: a document selecting unit configured to select one of a plurality documents; a setting unit configured to set a first type to a first annotation and to set a second type to a second annotation, wherein the first type indicates that the first annotation is displayed with a thumbnail image of the selected document and the second type indicates that the second annotation is displayed with a page image of the selected document; a selecting unit configured to select the thumbnail image or the page image as a display target; and a display unit configured to display an image and an annotation, wherein the display unit switches the annotation to be displayed based on the display target selected by the selecting unit, wherein the display unit displays the thumbnail image of the selected document with the first annotation of the first type being combined with the thumbnail image in a case where the thumbnail image is selected by the selecting unit, and displays the page image of the selected document with the second annotation of the second type being combined with the page image in a case where the page image is selected by the selecting unit, wherein, when an instruction is accepted that instructs merging of a first one of the plurality of documents to which a first document annotation is set and a second one of the plurality of documents to which a second document annotation is set, the display unit displays, as the thumbnail image of a document formed by merging the first and second documents, a thumbnail image including an image of the first document and the first and second document annotations, and when the first and second document annotations on the displayed thumbnail image overlap with each other, the display unit displays a thumbnail image including the image of the first document, the first document annotation and the second document annotation which is changed in position so as not to overlap with the first document annotation, and wherein at least one hardware processor executes process steps stored in a memory to function as at least one of the units.
