AMBIENT LIGHT PROBE

摘要

The examples relate to a method and apparatus to measuring ambient light information that is used in the manipulation or augmentation of an image presented on a display. The apparatus measures ambient light characteristic information from at least one direction in an environment in which the apparatus is located. The measured ambient light characteristic enable substantially real time generation and application of an image effect to an image presented on a display device.

1. An light probe, comprising:
a housing having a surface with a perimeter; a first sensor group comprising a plurality of light sensors, wherein: individual light sensors of the first sensor group are positioned in predetermined locations about the perimeter of the housing surface and oriented to receive ambient light from different respective directions; each of the light sensors of the first sensor group is configured to output a light intensity value in response to ambient light received at the respective predetermined location; a second sensor group comprising one or more light sensors positioned at a central position of the housing, wherein the second sensor group is configured to output color component values in response to ambient light received by the one or more light sensors at the central position of the housing; and a communication interface coupled to the first sensor group and the second sensor group, wherein the communication interface is configured to output light information representing the light intensity values and the color component values.
