Embodiment Construction

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0018] figure 1 It is a figure which shows the appearance structure of the projection control system concerning embodiment of this invention. The projection control system 1 is composed of a projection device 100 , a projection surface 200 , an imaging device 300 , and a projection control device 400 .

[0019] The projection device 100 is a device for projecting content onto the projection surface 200, and is composed of a projector including a projection lens, a projection element, a light source, and the like. The projection device 100 acquires content stored in a not-shown external storage device via the projection control device 400 and projects it on the projection surface 200 . In this embodiment, the projection device 100 projects the first projection image as content to the first area 510 of the projection area 500 that the projection device 100 can project o...

Abstract

The present invention provides a projection control device, a projection control method, and a recording medium capable of effectively utilizing a projection area. A projection control device (400) includes a feature acquisition unit (411) and an area determination unit (412). A feature acquisition unit (411) acquires shape information and color information of a projection surface. An area determination unit (412) determines a first area and a second area in a projection area that can be projected by the projection device on a projection surface, and the first area is projected with a first projected image corrected based on the acquired shape information and color information. , the second area is an area other than the first area corrected according to the acquired shape information and color information, and the second projected image is projected.

Description

technical field [0001] The present invention relates to a projection control device, a projection control method, and a recording medium. Background technique [0002] Conventionally, there is a technique (for example, refer to Japanese Patent Application Laid-Open No. 2015-173431 ) in which, in a projection installation such as a projector, the projection pixels of the projection device and the camera that captures the projection surface are determined so that projection can be performed appropriately even if the projection surface is a curved surface. The corresponding relationship between the imaging pixels of the device, and the projected image is corrected and projected according to the corresponding relationship. [0003] Generally, when a projected image is corrected and output as disclosed in JP-A-2015-173431, a reduced projected image is projected to a projected projection area of ​​the projection device in order to maintain the aspect ratio of the projected image. ...
