IMAGE DISPLAY CONTROL DEVICE, IMAGE DISPLAY SYSTEM, AND IMAGE DISPLAY CONTROL METHOD

摘要

An image display control device for displaying an image that is easy to view for a person is provided. The image display control device includes: an entry detector that detects, based on an image captured by an imaging device, an entry position through which a person entered a range of imaging; an entry direction identifying unit that identifies, based on the detected entry position and a center position of a region including a range of projection by a projecting device, an entry direction in which the person entered the range of imaging; a renderer that performs on an image data item a rotational rendering process in which an image to be projected by the projecting device is rotated according to the identified entry direction; and an output unit that outputs to the projecting device the image data item on which the rotational rendering process has been performed.

主权项

1. An image display control device for displaying an image using a projecting device and an imaging device, the projecting device obtaining an image data item and projecting onto a projection surface an image represented by the image data item, the imaging device capturing an image of at least a part of a region on the projection surface as a range of imaging, the region including a range of projection in which the image appears, the image display control device comprising:
a processor; and a non-transitory memory having stored thereon executable instructions, which when executed by the processor, cause the processor to: detect, based on the image captured by the imaging device, an entry position through which a person entered the range of imaging; identify, based on the detected entry position and a center position of the region, an entry direction in which the person entered the range of imaging; perform on the image data item a rotational rendering process in which the image to be projected by the projecting device is rotated according to the identified entry direction; and output to the projecting device the image data item on which the rotational rendering process has been performed.
