Mobile electronic device

摘要

A mobile electronic device 10 includes a projector 34, a camera 36, and a processing unit 22. The projector 34 projects an image, and the camera 36 captures the image projected by the projector 34. Based on first image information for causing the projector 34 to project a predetermined image and second image information obtained by capturing the image projected by the projector 34 based on the first image information by the camera 36, the processing unit 22 determines whether the projector 34 projects the predetermined image. When determining that the projector 34 fails to project the predetermined image, the processing unit 22 suppresses output of the projector 34 for projecting the image.

主权项

1. A mobile electronic device comprising:
an image projecting unit that projects an image in a projection area; an imaging unit that captures the image projected by the image projecting unit, and a processing unit that performs projection processing for causing the image projecting unit to project a predetermined image based on predetermined image information, wherein the image projecting unit projects the predetermined image based on a first image information, the imaging unit obtains a second image information by using a captured predetermined image projected by the image projecting unit, the processing unit further comprises a comparison determination unit that determines whether the predetermined image is the same as the captured predetermined image by comparing the first image information and the second image information, the processing unit suppresses projection performed by the image projecting unit when the comparison determination unit determines that the predetermined image is not the same as the captured predetermined image, the predetermined image is projected by the image projecting unit in an area that is smaller than the projection area and is included in the projection area, and the processing unit is configured to set the time, during which the image projecting unit projects the predetermined image based on the first image information, to be shorter than an updated cycle time during which the image is to be changed.
