Problems solved by technology

[0004] However, in a situation where the projection of a part of the image is blocked by an obstacle, a part of the warning display may not be recognized even if the warning display is displayed.
As a result, the content of the warning may not be conveyed to the user, and it may not be possible to take appropriate measures in time.

Embodiment Construction

[0019] Hereinafter, a projector that projects image light will be described with reference to the drawings. like figure 1 (a), figure 1 As shown in (b), the projector 1 is configured to include a housing 2 for accommodating the main body of the device. On the upper surface 2 t of the housing 2 , an input operation unit 21 for performing an input operation by the user and a display unit indicating the operating state of the projector 1 are arranged. LED (Light Emitting Diode: Light Emitting Diode) display unit 28 such as the like. In addition, on the upper surface 2t of the housing 2, an inclined portion 2s having a V-shaped depression in a side view is formed, and the projection window 3 and an obstacle sensor 25 as a detection portion are disposed on the inclined portion 2s. The projection window 3 is a portion that closes an opening formed in the housing 2 with a light-transmitting and heat-resistant member (for example, glass), and guides image light from the inside of th...

Abstract

A projector, adapted to project image light while making the image light wide-angle with a reflecting section to thereby display an image, includes a detection section adapted to detect an obstacle, which blocks the image light reflected by the reflecting section, a message display section adapted to display a warning message within the image if the detection section detects the obstacle, and a display position change section adapted to change a display position of the warning message within the image in accordance with passage of time.

Description

technical field [0001] The present invention relates to a projector for projecting image light and a control method thereof. Background technique [0002] When using a projector that projects image light, if an obstacle that blocks the image light enters near the projector, the obstacle is easily irradiated with light and becomes high in temperature, so extra care is required. Therefore, Patent Document 1 proposes a projector including a sensor that detects an obstacle (foreign object) entering an opening of a housing through which image light passes. If the projector detects the above-mentioned obstacle, it can display a warning on the OSD (on-screen display). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2007-34318 [0004] However, in a situation where the projection of a part of the image is blocked by an obstacle, even if a warning is displayed, a part of the warning may not be recognized. As a result, the content of the warning may not be conveyed to the...
