Abstract
A camera device including: an image capturing device configured to capture an image to generate an image signal; a housing in which the image capturing device is provided; a light transmitting cover coupled to the housing and configured to transmit light therethrough; a photometric sensor configured to sense an illuminance of light; an ultraviolet lamp provided on one side of the light transmitting cover and configured to irradiate an ultraviolet ray; and a controller configured to control the ultraviolet lamp according to an illuminance sensed by the photometric sensor, where the light transmitting cover is configured to exhibit a photochromic effect based on the ultraviolet ray irradiated by the ultraviolet lamp.
Claims21
A camera device comprising:
- an image capturing device configured to capture an image to generate an image signal;
- a housing in which the image capturing device is provided;
- a light transmitting cover coupled to the housing and configured to transmit light therethrough;
- a photometric sensor configured to sense an illuminance of light;
- an ultraviolet lamp provided on one side of the light transmitting cover and configured to irradiate an ultraviolet ray;
- and
- a controller configured to control the ultraviolet lamp according to an illuminance sensed by the photometric sensor,
- wherein the light transmitting cover is configured to exhibit a photochromic effect based on the ultraviolet ray irradiated by the ultraviolet lamp.
A camera device comprising:
- an image capturing device configured to capture an image to generate an image signal;
- a housing in which the image capturing device is provided;
- a light transmitting cover coupled to the housing, configured to transmit light therethrough, and comprising a photochromic material that exhibits a photochromic effect based on an ultraviolet ray irradiated from outside;
- and
- a controller configured to perform image signal processing on the generated image signal to generate an output image,
- wherein, based on an intensity of the ultraviolet ray being greater than a threshold value, the photochromic effect is generated in the light transmitting cover.
(canceled)
An image generation method performed by a camera device, the camera device comprising an image capturing device capturing an image to generate an image signal, a light transmitting cover transmitting light therethrough and exhibiting a photochromic effect based on an intensity of an ultraviolet ray, a photometric sensor sensing illuminance of light, and a ultraviolet lamp configured to irradiate an ultraviolet ray to an inner surface of the light transmitting cover, the image generation method comprising:
- sensing an illuminance of light by the photometric sensor;
- determining whether the illuminance of the light exceeds a predetermined threshold value;
- controlling the ultraviolet lamp to generate the photochromic effect in the light transmitting cover based on the illuminance of the light relative to the threshold value;
- and
- generating the image signal by the image capturing device based on the light transmitted through the light transmitting cover.
