Abstract
An image capturing device and an image capturing method thereof are provided. The image capturing device includes a plurality of infrared light sources, an image capturer and a controller. The infrared light sources respectively have a plurality of light types. The image capturer is configured to capture image information. The controller is coupled to the infrared light sources and the image capturer. The controller turns on or turns off each of the infrared light sources according to light intensity information, wherein at least one of the infrared light sources is turned on during an image capturing operation.
Claims10
An image capturing device, comprising:
- a plurality of infrared light sources, respectively have a plurality of light types, wherein the infrared light sources comprise a first infrared light source and a second infrared light source, and the first light source and the second light source have different light types;
- an image capturer, configured to capture image information, wherein the image capturer is configured to sense light intensity information;
- and
- a controller, coupled to the infrared light sources and the image capturer, the controller turns on or turns off each of the infrared light sources according to the light intensity information, wherein at least one of the infrared light sources is turned on during an image capturing operation,
- wherein the controller is configured to:
- turn on the first infrared light source;
- determine whether the light intensity information is less than a first threshold after the first infrared light source is turned on;
- determine whether an exposure setting time of the image capturing device is a maximum value in response to determining that the light intensity information is less than the first threshold;
- and
- in response to determining that the exposure setting time is the maximum value, turn on the second light source while maintaining the first light source on.
An image capturing method, comprising:
- providing a plurality of infrared light sources, wherein the infrared light sources respectively have a plurality of light types, wherein the infrared light sources comprise a first infrared light source and a second infrared light source, and the first light source and the second light source have different light types;
- providing an image capturer to capture image information, wherein the image capturer is configured to sense light intensity information;
- providing a controller to turn on or turn off each of the infrared light sources according to the light intensity information, wherein at least one of the infrared light sources is turned on during an image capturing operation;
- turning on the first infrared light source;
- determining whether the light intensity information is less than a first threshold after the first infrared light source is turned on;
- and
- determining whether an exposure setting time of the image capturing device is a maximum value in response to determining that the light intensity information is less than the first threshold;
- and
- in response to determining that the exposure setting time is the maximum value, turning on the second light source while maintaining the first light source on.
