Abstract
The image capture system of the present disclosure comprises an illuminator comprising at least one infrared light LED or laser and one visible light LED, an image sensor that is sensitive to infrared light and visible light, a memory configured to store instructions, and a processor configured to execute instructions to cause the image capture system to emit infrared light, receive image data comprising at least one infrared image, and determine depth maps, visible focus settings, or infrared exposure settings based on the infrared image data.
Claims17
An image capture system, comprising:
- an illuminator configured to emit infrared light having at least one infrared wavelength and emit visible light having at least one visible wavelength;
- at least one image sensor having a sensitivity to an infrared range of wavelengths that includes the at least one infrared wavelength and a visible range of wavelengths that includes the at least one visible wavelength;
- at least one processor coupled to the illuminator and the at least one image sensor;
- and
- a memory configured to store instructions, that, when executed by the at least one processor, cause the image capture system to perform operations, the operations comprising:
- emitting infrared light from the illuminator;
- while the infrared light is being emitted, capturing at least one infrared image with the at least one image sensor;
- determining a depth map based on the at least one infrared image;
- determining an infrared exposure setting based on the depth map;
- scaling the infrared exposure setting to determine a visible exposure setting;
- determining an infrared focus setting based on the depth map;
- scaling the infrared focus setting to determine a visible focus setting;
- emitting visible light from the illuminator;
- and
- while the visible light is being emitted, capturing a visible image with the at least one image sensor using the visible exposure setting and the visible focus setting.
