Abstract

A projection control device comprises a projection control unit, an image acquisition unit, and a corresponding determination unit. The projection control unit outputs a synthesis pattern light to a screen. The synthesis pattern light comprises plurality of pattern light including light area of different wave range from each other. The image acquisition unit acquires a captured image includes the synthesis pattern light which has been outputted to the screen, wherein the captured image is captured by an image capture unit. The corresponding determination unit determines a relationship between projection pixels of the projector and pixels of the captured image of the image capture unit, on the basis of the synthesis pattern light on the captured image.

Claims (37)

1. A projection control device comprising a hardware processor;

wherein the hardware processor configured to;

perform a projector to output a synthesis pattern light to a screen, wherein the synthesis pattern light comprising plurality of pattern light including light area of different wave range from each other;

acquire a captured image includes the synthesis pattern light which has been outputted to the screen, wherein the captured image is captured by an image capture unit; and

determine a relationship between projection pixels of the projector and pixels of the captured image of the image capture unit, on the basis of the synthesis pattern light on the captured image.

2. The projection control device according to claim 1 ,

wherein the plurality of pattern light are three pattern light including a light area of a monochromic wave range of each of RGB.

3. The projection control device according to claim 1 ,

wherein the plurality of pattern light include the respective areas disposed on the basis of a gray code.

4. The projection control device according to claim 1 ,

wherein the plurality of pattern light include the respective areas extending in a predetermined direction.

5. The projection control device according to claim 1 ,

wherein the plurality of pattern light comprises at least pattern light including the area extending in a predetermined direction and pattern light including the area extending in a direction orthogonal to the predetermined direction.

6. The projection control device according to claim 1 ,

wherein the hardware processor is configured to correct a projection target image to be outputted to the projector, on the basis of the determined relationship.

7. The projection control device according to claim 1 ,

wherein the hardware processor is configured to:

acquire influence information representing an influence rate of the light of the different wave range from each other with respect to the captured image, on the basis of a wave range image obtained by capturing the screen to which the light of the different wave range from each other is outputted by the projector with the image capture unit; and

determine a relationship between the projection pixels of the projector and pixels of the captured image of the image capture unit on the basis of the synthesis pattern light on the captured image which is corrected on the basis of the influence information.

8. The projection control device according to claim 7 ,

wherein the plurality of pattern light are three pattern light including a light area of a monochromic wave range of each of RGB.

9. The projection control device according to claim 1 ,

wherein the hardware processor is configured to:

determine a relationship between wavelengths of the projector and the image capture unit;

perform the projector to output the light of the different wave range from each other to the screen;

capture the light of the different wave range from each other which has been outputted to the screen wherein the light of the different wave range from each other is captured by the image capture unit; and

determine the relationship between the wavelengths of the projector and the image capture unit, on the basis of the light of the different wave range from each other which is outputted by the projector, and the light of the different wave range from each other which is captured by the image capture unit.

10. The projection control device according to claim 9 ,

wherein the plurality of pattern light are three pattern light including a light area of a monochromic wave range of each of RGB.

11. A projection control method comprising:

causing a projector to output synthesis pattern light to a screen, wherein the synthesis pattern light comprises plurality of pattern light including a light area of different wave range from each other;

acquiring a captured image including the synthesis pattern light which has been outputted to the screen, wherein the captured image is captured by an image capture unit; and

determining a relationship between projection pixels of the projector and pixels of the captured image of the image capture unit, on the basis of the synthesis pattern light on the captured image.

12. A non-transitory storage medium encoded with a computer-readable program that enables a computer to execute functions as:

causing a projector to output synthesis pattern light to a screen, wherein the synthesis pattern light comprises plurality of pattern light including a light area of different wave range from each other;

acquiring a captured image including the synthesis pattern light which has been outputted to the screen, wherein the captured image is captured by an image capture unit; and

determining a relationship between projection pixels of the projector and pixels of the captured image of the image capture unit, on the basis of the synthesis pattern light on the captured image.
