Depth sensor using modulated light projector and image sensor with color and IR sensing |
摘要 |
An electronic device includes a modulated light projector to project an infrared light pattern and an image sensor. The image sensor includes an array of photosensors and a filter array overlying the array of photosensors. The filter array comprises a mosaic of color filter elements and infrared filter elements, each color filter element overlying a corresponding photosensor of a first subset of photosensors and each infrared filter element overlying a corresponding photosensor of a second subset of photosensors. The electronic device further includes a controller to, in a first mode, control the image sensor to capture a color image using the first subset of photosensors and, in a second mode, control the image sensor to capture a depth image representing a reflection of the infrared light pattern using the second subset of photosensors. |

1. An electronic device comprising:
a modulated light projector to project an infrared light pattern; and an image sensor comprising:
an array of photosensors; anda filter array overlying the array of photosensors and comprising a mosaic of color filter elements and infrared filter elements, each color filter element overlying a corresponding photosensor of a first subset of photosensors and each infrared filter element overlying a corresponding photosensor of a second subset of photosensors, wherein each photosensor of the first subset has a first size and each photosensor of the second subset has a second size different than the first size; anda controller to, in a first mode, control the image sensor to capture a color image using the first subset of photosensors and, in a second mode, control the image sensor to capture a depth image representing a reflection of the infrared light pattern using the second subset of photosensors. |
