Embodiment Construction

[0044] [1. Outline of projection system]

[0045] figure 1 It is a perspective view of the projection system 1 in one embodiment of the present invention. The projection system 1 has a projector 100 and an indicator 70 .

[0046] The projector 100 projects image light onto a projection object, thereby forming an image on a surface of the projection object. figure 1 A configuration example in which the projector 100 projects onto a screen SC (projection surface) made of a plane is shown. The projection target of an image projected by the projector 100 is not limited to a flat surface, and the screen SC may be, for example, a curtain or a wall. The function and operation of the projector 100 to project an image onto the screen SC correspond to "display" of the display device.

[0047] exist figure 1 In the configuration example of , the projector 100 is installed above the screen SC, and the projector 100 projects image light downward to form a projection image DP on the sc...

Abstract

The invention provides a projector and a method for controlling the projector. The success rate in the case where a projector captures a projected image and performs calibration is improved, thereby achieving high efficiency. The projector (100) includes an image projection section (260), an imager (460), a calibration processor (215) that performs calibration, an information acquirer (213) that acquires information on the state in which the projector (100) is installed, and an image generator (214) that generates a calibration image corresponding to the state in which the projector (100) is installed, and the calibration processor (215) causes the image projection section to project the calibration image generated by the image generator (214) to perform the calibration.

Description

technical field [0001] The invention relates to a projector and a control method of the projector. Background technique [0002] Conventionally, there are known projectors that project a calibration image including a marker for specifying a position and perform calibration based on a captured image obtained by capturing the projected image (for example, refer to Patent Documents 1 and 2). In such a projector, the process of detecting a marker from a captured image may fail due to distortion of the shape of the marker in the captured image or the like. Therefore, a method of recalibrating by changing the conditions when the calibration fails has been proposed. For example, in the projector described in Patent Document 2, when detection of a mark fails, calibration is performed using a different type of calibration image.
