Imaging method including synthesizing second image in area of screen that displays first image
Since an image projected from a projector has basically not high quality due to degradation of brightness and mixture of outside light, the image shot by the conventional technology includes the projected image with basically not high quality. In order to solve the above deficiency, in an aspect of the present invention provides an image system, where live performance is provided to audience by image projection on the screen, and the image to be shot does not include the projected image with low quality. For example, the image system can later synthesize a high-quality image having the same content as the projected image.
1. An imaging method, the method causing a computer to execute processes, comprising:
projecting intermittently a first image on a screen by a projector based on source image data;
imaging the screen and a peripheral area of the screen at a non-projection timing for the intermittently projected first image by an imager so as to obtain captured image data;
acquiring imager information including:
an imager relative position of the imager with respect to the screen; and
an imaging angle of the imager with respect to the screen;
generating composition image data based on the source image data and the imager information, and
composing the composition image data with the capture image data so as to generate a composition image, wherein
the composition image includes a second image representing the composition image data composed in an area corresponding to the screen and a third image representing the captured image data composed in an area corresponding to the peripheral area.
2. The imaging method according to claim 1 , wherein the imaging further comprises imaging the screen and the peripheral area at a projection timing through a filter preventing transmission of the first image displayed on the screen.
3. The imaging method according to claim 2 , wherein the filter is a shutter for imaging the screen and the peripheral area only at the non-projection timing.
4. The imaging method according to claim 1 , wherein the screen is at least partially metal or is coated with metal powder paint.
5. The imaging method according to claim 1 , wherein the screen is a semi-transmissive screen.
6. The imaging method according to claim 1 , wherein the screen is a half mirror that partially reflects and partially transmits incoming light.
7. The imaging method according to claim 6 , wherein the projector is a display monitor so that the first image is displayed on the display monitor.
8. The imaging method according to claim 1 , wherein the second image has a same content as the first image.
9. An image system that is configured to execute processes by a processor, the system comprising:
a projector configured to project a first image on a screen based on source image data;
an imager configured to shoot the screen and a peripheral area of the screen via a filter, which prevents transmission the first image displayed on the screen, so as to obtain captured image data; and
a composition unit
configured to acquire imager information including:
an imager relative position of the imager with respect to the screen; and
an imaging angle of the imager with respect to the screen,
configured to generate composition image data based on the source image data and the imager information, and
configured to compose the composition image data with the captured image data so as to generate a composition image, wherein
the composition image includes a second image representing the composition image data composed in an area corresponding to the screen and a third image representing the captured image data composed in an area corresponding to the peripheral area.
10. The image system according to claim 9 , wherein
the projector is configured to project the first image intermittently on the screen, and
the filter is a shutter for shooting the screen and the peripheral area at a non-projection timing of the projector.
11. The image system according to claim 9 , wherein
the first image projected on the screen is a polarized image under a predetermined condition, and
the filter prevent the polarized image under the predetermined condition from transmitting through the filter.
12. The image system according to claim 9 , wherein
the screen is at least partially metal or is coated with metal powder paint.
13. The image system according to claim 9 , wherein
the screen is a semi-transmissive screen.
14. The image system according to claim 9 , wherein
the screen is a half mirror that partially reflects and partially transmits incoming light.
15. The image system according to claim 9 , wherein
the projector is a display monitor so that the first image is displayed on the display monitor.
16. The image system according to claim 9 , wherein
the second image has a same content as the first image.
