Abstract
A camera device includes an image capturing device disposed in a housing and configured to generate an image signal by capturing an image. A light transmitting cover is coupled to the housing and allows light to pass therethrough toward the image capturing device. The camera device further includes a photometric sensor that senses an illuminance of light and an ultraviolet lamp disposed on one side of the light transmitting cover to irradiate ultraviolet radiation toward the cover. Operation of the ultraviolet lamp is controlled according to the illuminance sensed by the photometric sensor. The light transmitting cover exhibits a photochromic effect in response to the ultraviolet radiation irradiated by the ultraviolet lamp.
Claims19
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, and
- wherein the photometric sensor comprises:
- an internal photometric sensor provided inside the light transmitting cover and configured to sense an illuminance of light that is transmitted through the light transmitting cover;
- and
- an external photometric sensor provided outside the light transmitting cover and configured to sense an illuminance of external light.
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, and
- wherein the controller is further configured to generate the output image according to a first image based on light transmitted through the light transmitting cover in which the photochromic effect is generated according to an ultraviolet ray of a first intensity and a second image based on light transmitted through the light transmitting cover in which the photochromic effect is generated according to an ultraviolet ray of a second intensity lower than the first intensity.
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;
- an external photometric sensor provided outside the light transmitting cover and configured to sense an illuminance of external light;
- an ultraviolet lamp provided on one side of the light transmitting cover and configured to irradiate an ultraviolet ray;
- a controller configured to control the ultraviolet lamp according to an illuminance sensed by the external photometric sensor;
- and
- an internal photometric sensor provided inside the light transmitting cover and configured to sense an illuminance of light that is transmitted through the light transmitting cover,
- wherein the light transmitting cover is configured to exhibit a photochromic effect based on the ultraviolet ray irradiated by the ultraviolet lamp, and
- wherein, based on the illuminance sensed by the external photometric sensor exceeding a threshold value, the controller is further configured to turn on the ultraviolet lamp to generate the photochromic effect in the light transmitting cover.
