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 can project an image and that is an area not displaying the main image to which the keystone correction is applied;
- 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 non-transitory computer-readable medium recording a program, wherein the program includes a series of commands that causes a computer to execute functions 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 to which the keystone correction is applied;
- 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.
