Selective colorization using monochromic imagery
First Claim
1. A method comprising:
- capturing, using an image sensor, a first image as a black and white image associated with a first color channel;
determining image information associated with the first image, wherein the information includes at least one of position information, navigation information, elevation information, image attribute information, or image capture information;
analyzing the image information to detect a triggering event;
detecting the trigger event in response to analyzing the image information; and
in response to detecting the triggering event;
causing light to pass through a color filter associated with a second color channel that is different than the first color channel;
capturing a second image associated with the second color channel; and
creating a multi-channel color image using the first image and the second image.

Abstract
An unmanned aerial vehicle (UAV) may include stereo cameras that include a left camera and a right camera. The cameras may capture a majority of images in black and white, which may be captured in a single color channel. At certain times during a flight, the UAV may be configured to generate colorized images. To generate colorized images, the camera may capture a first image using a default color channel (e.g., green), which may be used for black and white images, and then selectively apply a color filter to capture a second image associated with a different color channel than the first image. A multi-channel color image may be created using at least the first image and the second image. By adding a third image in the remaining color channel, the created image may be generated as a red-green-blue image.

11. A system comprising:
-
an image sensor configured to capture at least a first image associated with at least one color channel; one or more processors; and one or more non-transitory computer-readable media storing instructions executable by the one or more processors, wherein the instructions program the one or more processors to perform operations comprising; causing the image sensor to capture the first image as a black and white image associated with a first color channel; determining information associated with the first image; analyzing the information to detect a trigger event; detecting the trigger event in response to analyzing the information; and in response to detecting the triggering event; causing light to pass through a color filter associated with a second color channel that is different than the first color channel; causing the image sensor to capture a second image associated with the second color channel; and creating a multi-channel color image using the first image and the second image. - View Dependent Claims (12, 13, 14, 15)

16. One or more non-transitory computer-readable media maintaining instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
-
causing an image sensor to capture a first image as a black and white image associated with a first color channel; determining information associated with the first image; analyzing the information to detect a trigger event; detecting the trigger event in response to analyzing the information; and in response to detecting the triggering event; causing light to pass through a color filter associated with a second color channel that is different than the first color channel; causing the image sensor to capture a second image associated with the second color channel; and creating a multi-channel color image using the first image and the second image. - View Dependent Claims (17, 18, 19, 20)
