Abstract
A sensor apparatus includes a photosensitive sensor, a cover, and a moving mechanism. The photosensitive sensor includes a first lens and a second lens which focus on a photosensitive element. The cover includes a first slit arranged on an optical axis of the first lens and a second slit arranged on an optical axis of the second lens. The moving mechanism is configured to move the photosensitive sensor and the cover relative to each other so that the second slit is arranged on the optical axis of the first lens.
Claims1
An image processing device, comprising:
- an infrared sensor including a first lens and a second lens which focus on an element;
- a cover having a first slit and a second slit, the first slit arranged on an optical axis of the first lens, the second slit arranged on an optical axis of the second lens;
- a moving mechanism configured to relatively move the infrared sensor and the cover so that the second slit is arranged on the optical axis of the first lens;
- an image processor configured to process an image;
- and
- a controller configured to control power supplied to the image processor, and to control the image processor to switch to a normal mode in which all power necessary for the image processor is supplied when a detection signal of the infrared sensor is received in a power saving mode in which power supplied to a part of the image processor is limited.
