Intensity modeling for rendering realistic images

摘要

An electronic device can utilize one or more sensors and/or imaging elements to determine the relative position of at least one light source relative to the device. In various embodiments, the intensity of light can be determined in various directions around the device. By determining the relative intensity around the device, an approximate direction of one or more light sources can be determined. Utilizing the relative position of each light source, the electronic device can properly light or shade a graphical object to be rendered by the device, or otherwise process image information captured by the device.

主权项

1. A computer-implemented method of displaying an image on an electronic device, comprising:
determining, using a light sensor, light information from a plurality of substantially straight different light paths of the electronic device, the light paths being configured to capture light from different primary directions with respect to the electronic device and direct the light to the light sensor, and including: an entrance, and an exit; determining a light type corresponding to the light information, the light type being one of a point light source or a non-point light source; determining a relative intensity value of the light information from the plurality of light paths; based at least in part upon the relative intensity value and the primary directions of the light paths, determining light source information including at least a projection direction of a light source relative to the electronic device; rendering the image based at least in part on the light information and the light type, the rendering the image including at least one of a lighting process, a shading process and a glint process, wherein the image rendered based on the light type being the point light source is different than a second image that would have been rendered based on the light type being the non-point light source; and providing the image for display on the electronic device.
