Abstract

Provided are a non-transitory computer-readable storage medium storing a display control program, an image display apparatus and a display control method. The apparatus includes a touch panel configured to receive a handwriting input and display a document and handwriting information in a display area thereof. The display control program, when being executed by a processor of the apparatus, causes the processor to perform the following processes. The processes includes: operating the touch panel to display a document and handwriting information in the display area; and in response to detecting an operation onto the document, controlling display of the handwriting information by using a first display mode or a second display mode. The first display mode is a mode to display the handwriting information with being associated with the document. The second display mode is a mode to display the handwriting information with being associated with the display area.

accepting an input of handwriting information via the touch panel;

accepting a designation of a display mode as one of a first display mode and a second display mode;

adding display mode designation information to the handwriting information, to designate the handwriting information as handwriting information designated to be displayed in the first display mode or as handwriting information designated to be displayed in the second display mode, in accordance with the designated display mode;

displaying the handwriting information in the display area; and

in response to detecting an input operation to change the display of the document displayed in the display area, (i) changing the display of the document in accordance with the input operation, (ii) controlling the display of the handwriting information designated to be displayed in the first display mode such that the display of the handwriting information is changed in a same manner as the display of the document, and (iii) controlling the display of the handwriting information designated to be displayed in the second display mode such that a display state of the handwriting information is maintained even if the input operation is one of a page turning operation which turns a page of the document in the display area, a movement operation which moves the displayed content in the display area, an enlargement operation which enlarges the displayed content in the display area, and a reduction operation which reduces the displayed content in the display area.

2. The non-transitory computer-readable storage medium of claim 1, wherein the processes further comprise:

assigning an image of the document to a first layer;

assigning an image of the handwriting information designated to be displayed in the first display mode, to a second layer;

assigning an image of the handwriting information designated to be displayed in the second display mode, to a third layer; and

displaying the first layer, the second layer, and the third layer such that the first, second, and third layers overlap in the display area, thereby displaying the document in the display area and displaying the handwriting information in the display area.

3. The non-transitory computer-readable storage medium of claim 2, wherein the processes further comprise, in response to receiving a designation of a region of the document on the first layer, assigning an image of the document within the region or an image of the document outside the region, to the third layer.

4. The non-transitory computer-readable storage medium of claim 2, wherein the processes further comprise, in response to receiving a designation of a region of the handwriting information on the second layer, assigning an image of the handwriting information within the region or an image of the handwriting information outside the region, to the third layer.

5. The non-transitory computer-readable storage medium of claim 2, wherein the controlling the display of the handwriting information designated to be displayed in the second display mode comprises, upon the document on the first layer moving relative to the display area, maintaining a location of the handwriting information on the third layer relative to the display area.

6. The non-transitory computer-readable storage medium of claim 2, wherein the processes further comprise, upon the handwriting information on the third layer moving relative to the display area, maintaining a location of the document on the first layer relative to the display area.

7. The non-transitory computer-readable storage medium of claim 2, wherein the processes further comprise storing the handwriting information on the third layer into a storage, as data separated from the document on the first layer.

8. The non-transitory computer-readable storage medium of claim 7, wherein the storing the handwriting information on the third layer includes storing data of the handwriting information on the third layer into the storage, in association with a certain document, and

wherein the processes further comprise:

reading the data of the handwriting information associated with the certain document, from the storage, and

operating the touch panel to display the certain document together with the handwriting information associated with the certain document, in the display area.

9. The non-transitory computer-readable storage medium of claim 2, wherein the processes further comprise storing the document on the first layer, the handwriting information on the second layer and the handwriting information on the third layer into a storage together as one piece of data.

10. An image display apparatus comprising:

a touch panel; and

a controller configured to;

display a document in a display area of the touch panel;

accept an input of handwriting information via the touch panel;

accept a designation of a display mode as one of a first display mode and a second display mode;

add display mode designation information to the handwriting information, to designate the handwriting information as handwriting information designated to be displayed in the first display mode or as handwriting information designated to be displayed in the second display mode, in accordance with the designated display mode;

display the handwriting information in the display area; and

in response to detecting an input operation to change the display of the document displayed in the display area, (i) change the display of the document in accordance with the input operation, (ii) control the display of the handwriting information designated to be displayed in the first display mode such that the display of the handwriting information is changed in a same manner as the display of the document, and (iii) control the display of the handwriting information designated to be displayed in the second display mode such that a display state of the handwriting information is maintained even if the input operation is one of a page turning operation which turns a page of the document in the display area, a movement operation which moves the displayed content in the display area, an enlargement operation which enlarges the displayed content in the display area, and a reduction operation which reduces the displayed content in the display area.

11. A display control method of an apparatus comprising a touch panel, the method comprising:

displaying a document in a display area of the touch panel;

accepting an input of handwriting information via the touch panel;

accepting a designation of a display mode as one of a first display mode and a second display mode;

adding display mode designation information to the handwriting information, to designate the handwriting information as handwriting information designated to be displayed in the first display mode or as handwriting information designated to be displayed in the second display mode, in accordance with the designated display mode;
