Abstract
A corrector corrects a main image acquired by an image acquirer based on correction setting acquired by a correction setting acquirer, and stores corrected main image in a buffer. An unused area detector detects the area that has not stored the corrected main image in the buffer, and transmits the result to a sub-image selector. The sub-image selector selects, among sub-image candidates registered in a sub-image information memory, a candidate that can be displayed on the unused area and has the highest priority as a sub-image. The sub-image controller executes a program stored in the sub-image displaying program memory, and displays the selected sub-image on the unused area.
Claims10
A projector control device comprising:
- a projection controller that performs a keystone correction on a main image that is a major image projected and displayed on a projection plane, and causes a projection device to project a corrected main image;
- a detector that detects an unused area to which the projection device project an image and that is an area not displaying the main image applied the keystone correction;
- and
- a sub-image acquirer that acquires a sub-image to be displayed on at least a part of the unused area detected by the detector,
- wherein the projection controller controls the projection device to project the sub-image to at least the part of the unused area.
A computer-readable medium recording a program, wherein the program includes a series of commands that causes a computer to execute a function including:
- a process that performs a keystone correction on a main image that is a major image displayed at the time of projecting and displaying an image on a projection plane, and causes a projection device to project a corrected main image;
- a detection process that detects an unused area to which the projection device can project an image and that is an area not displaying the main image applied the keystone correction;
- a process that acquires a sub-image to be displayed on at least a part of the unused area detected by the detection process;
- and
- a process that causes the projection device to project the sub-image to at least a part of the unused area.
