| 发明名称 | Projector having illuminance sensor and obstacle sensor with light emitting section | ||
| 摘要 | Illuminance in a space where a projector projects an image is accurately detected with failure of the projector due to heat accumulation prevented. The projector includes a window that allows light to pass therethrough, a projection section that projects light through the window to project an image, an illuminance sensor that detects illuminance in a space where the image is projected, an obstacle sensor that has a light emitting section and a light receiving section, the light emitting section emitting second light, the light receiving section receiving the second light, the obstacle sensor detecting an obstacle based on an output from the light receiving section, and a control section that disables the detection of the illuminance during a period for which the light emitting section emits the light. | ||

| 主权项 | 1. A projector comprising: a window that allows light to pass therethrough; a projection section that projects first light through the window to project an image; an illuminance sensor that detects illuminance in a space where the image is projected; an obstacle sensor that has a light emitting section and a light receiving section, the light emitting section emitting second light, the light receiving section receiving the second light, the obstacle sensor detecting an obstacle based on an output from the light receiving section; and a control section that disables the detection of the illuminance by the illuminance sensor during a period for which the light emitting section emits the second light. | ||
