摘要： An active depth imaging system and method of operating the same captures illuminator-on and illuminator-off image data with each of a first and second imager. The illuminator-on image data includes information representing an imaged scene and light emitted from an illuminator and reflected off of objects within the imaged scene. The illuminator-off image data includes information representing the imaged scene without the light emitted from the illuminator. For each image set captured by the first and second imagers, illuminator-off image data is subtracted from the illuminator-on image data to identify the illuminated light within the scene. The depth of an object at which the light is incident on then is determined by the subtracted image data of the first and second imagers.

Pixel data is read from the plurality of regions of pixels. The pixel data is interpolated from a first one of the plurality of regions of pixels to determine the pixel data of the regions of pixels other than the first one of the plurality of regions of pixels to generate a first image having the first exposure time. The pixel data is interpolated from the second one of the plurality of regions of pixels to determine the pixel data of the regions of pixels other than the second one of the plurality of regions to generate a second image having the second exposure time.

摘要： Generating an image with an imaging system includes capturing a first sub-image during a first exposure with a first pixel subset of an image sensor of the imaging system, capturing a second sub-image during a second exposure with a second pixel subset of the image sensor, capturing a third sub-image during a third exposure with a third pixel subset of the image sensor, and capturing a fourth sub-image during a fourth exposure with a fourth pixel subset of the image sensor. The first, second, third, and fourth exposures have different durations. A preferred exposure is selected from between the first, second, third and fourth exposures by analyzing the first, second, third, and fourth sub-images. Then, a full-resolution image is captured at the preferred exposure. An HDR image is generated based on the full-resolution image and the sub-images.
