IMAGE DISPLAY APPARATUS AND IMAGE DISPLAY METHOD
First Claim
1. An image display apparatus comprising:
- an image display unit to display an image on a screen;
a handwriting acceptance unit to accept handwriting input to the image;
a handwriting display unit to display the handwriting on the image;
a detection unit to detect one or more object regions including respective one or more certain objects included in the image;
an object region display unit to display information indicating the object region on the image;
a determination unit to determine whether the handwriting is directed to any one of the object regions or not on the basis of the handwriting and the object region;
an object identification unit that, in a case where the determination unit determines that the handwriting is directed to any one of the object regions, identifies an identified region being the object region to which the handwriting is directed;
a placement region identification unit to identify a placement region for placing the handwriting to the identified region;
a calculator to calculate a scaling ratio in a scaling process executed on the handwriting for displaying the handwriting in the placement region;
a scaling unit to execute the scaling process on the handwriting according to the scaling ratio;
a display region extraction unit to extract a display region for displaying handwriting after the scaling process from the placement region; and
a scaled handwriting display unit to display the handwriting after the scaling process in the display region.

Abstract
A PC displaying an image on a display unit accepts handwriting input to the image, and displays the accepted handwriting on the image. The PC detects object regions including a certain object in the image and comment placement regions corresponding to respective object regions. If the starting position of the first stroke of handwriting is included in any one of the object regions, the PC determines that the accepted handwriting is directed to the object region. When the input of the handwriting to the object region is finished, the PC identifies a display region for the handwriting and changes the size of the input handwriting so as to display the input handwriting in the comment placement region corresponding to the object region. The PC displays the size-changed handwriting in the identified display region and further displays a comment balloon surrounding the displayed handwriting.

14. An image display method including:
-
displaying an image on a display unit; accepting handwriting input to the displayed image; displaying the accepted handwriting on the image; detecting one or more object regions including respective one or more prescribed objects included in the image; displaying information indicating the detected object region on the image; determining whether the handwriting is directed to any one of the detected object regions or not on the basis of the accepted handwriting and the detected object region; identifying an identified region being the object region to which the handwriting is directed when the handwriting is directed to any one of the object regions; identifying a placement region for placing the handwriting to the identified region; calculating a scaling ratio in a scaling process executed on the handwriting for displaying the handwriting in the identified placement region; executing the scaling process on the handwriting according to the calculated scaling ratio; extracting a display region for displaying handwriting after the scaling process from the identified placement region; and displaying the handwriting after the scaling process in the extracted display region.

15. A storing medium storing a computer program causing a computer to execute processes of:
-
displaying an image on a display unit, accepting handwriting input to the displayed image, displaying the accepted handwriting on the image, detecting one or more object regions including respective one or more prescribed objects included in the image; displaying information indicating the detected object region on the image; determining whether the handwriting is directed to any one of the detected object regions or not on the basis of the accepted handwriting and the detected object region; identifying an identified region being the object region to which the handwriting is directed when the handwriting is directed to any one of the object regions; identifying a placement region for placing the handwriting to the identified region; calculating a scaling ratio in a scaling process executed on the handwriting for displaying the handwriting in the identified placement region; executing the scaling process on the handwriting according to the calculated scaling ratio; extracting a display region for displaying handwriting after the scaling process from the identified placement region; and displaying the handwriting after the scaling process in the extracted display region.
