    摘要: Method and apparatus for duplicating a target color and changing a color of an object to match the target color. A first color sensor measures the target color. A color projection mechanism selectively changes the color of the object. A color matching mechanism is coupled to the first color sensor for receiving the target color. Based on the target color, the color matching mechanism controls the color projection mechanism to change the color of the object to match the target color.

    摘要: A light source having a first mixing chamber, a light pipe structure, and a controller is disclosed. The first mixing chamber includes a first plurality of LEDs, the first mixing chamber having a first transparent window through which light from the first plurality of LEDs exits the first mixing chamber. The light pipe structure has a first end optically coupled to the window such that light from the first plurality of LEDs enters the first end and a second end through which the light exits. The controller determines the power that is applied to the first plurality of LEDs and includes a photodetector optically coupled to the second end of the light pipe structure. The photodetector generates signals indicative of an intensity of light generated by the LEDs, the controller causing the LEDs to be powered such that the signal matches a target value.

    摘要: An ambient light sensor (ALS) system is described. The ALS system includes a polychromatic color sensor, an analog-to-digital converter (ADC), and a digital processor. The polychromatic color sensor generates a plurality of analog signals from a corresponding plurality of color channels based on a detected ambient light signal. The ADC is coupled to the polychromatic color sensor. The ADC converts the plurality of analog signals to a plurality of digital signals. The digital processor is coupled to the ADC. The digital processor generates a processed light signal. The processed light signal describes a characteristic of the detected ambient light signal. Embodiments of the ALS system provide a more comprehensive characterization of the ambient light, and facilitate control of a device based on the characterization of the ambient light.
