Problems solved by technology

[0006] However, since the projected image may overlap with the image of the handwriting input surface, the projected image may not be seen clearly.
In addition, in the case of instructing a process using the operation member provided on the main body, it is necessary to extend the hand to the operation member every time an instruction is given, so the instruction cannot be easily performed.

Embodiment Construction

[0016] Next, a projector according to an embodiment of the present invention will be described with reference to the drawings. figure 1 It is a perspective view showing a state during image projection by the projector according to the embodiment. The projector 2 has a housing 4 made of metal or plastic. On the front surface 6 of the housing 4 are provided a projection window 8 and photographing windows 10a, 10b. The projection part 30 (refer to figure 2 ), the photography windows 10a, 10b are used to allow the subject light to enter the imaging units 44a, 44b built in the casing 4 (see image 3 ). In addition, on the upper surface 12 of the casing 4, a power switch 14 and a projection button 16 for projecting an image are provided. In addition, various input terminals not shown are provided on the back surface of the housing 4 .

[0017] The projector 2 is installed upright so that the lower surface of the casing 4 is in contact with the installation surface G which is a ...

Abstract

Provided are: a projection unit that projects an image displayed on an image formation region of a display unit, and projects an icon displayed on a non-image formation region other than the image formation region, onto a projection surface; an imaging unit that images a region that includes the icon on the projection surface; a detection unit that detects the selection of the region that includes the icon, based on imaging data output from the imaging unit; and a processing unit that, when the selection of the region that includes the icon is detected by the detection unit, performs processing indicated by the icon included in the selected region.

Description

[0001] The disclosure of the following application from which priority is claimed is incorporated herein by reference: Japanese Patent Application No. 2010-40818 filed on February 25, 2010. technical field [0002] The present invention relates to projectors. Background technique [0003] Conventionally, there is an input device that recognizes that a handwriting input surface projected on a table or the like is pointed with a pen or a user's finger based on an image signal obtained by imaging the handwriting input surface (for example, refer to Patent Document 1). [0004] prior art literature [0005] Patent Document 1: Japanese Patent Laid-Open No. 2008-134793 [0006] However, since the projected image may overlap with the image of the handwriting input surface, the projected image may not be seen clearly. In addition, when instructing a process using an operation member provided on the main body, it is necessary to reach out to the operation member every time an inst...
