Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, PROGRAM, AND PROJECTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/225530
Kind Code:
A1
Abstract:
The present disclosure relates to an image processing device, an image processing method, a program, and a projector device that facilitate prompt correction for the effect on the surface shape and the color on a projection surface. A correction vector calculating unit calculates a correction vector used for projection-surface distortion correction for correcting distortions generated in an image according to the surface shape of a projection surface on the basis of a test pattern image acquired by capturing a test pattern projected onto an arbitrary projection surface. A correction data generating unit generates correction data used for projection-surface color correction for correcting image colors according to the color of the projection surface on the basis of the test pattern image. The test pattern is formed from round dots arranged in a grid pattern on a white background. The test pattern image used to calculate the correction vector and to generate the correction data is acquired by a single capture of the test pattern. The present technique is applicable to, for example, a projector device equipped with a projection unit and an imaging unit.
