1. A method of transmitting an image stream together with color metadata, comprising:
capturing image frames of a first image stream;
capturing image frames of a second image stream, using camera settings for increasing an amount of color information in the second image stream compared to an amount of color information in the first image stream;
detecting an object in a first image frame of the first image stream;
identifying the object in a second image frame of the second image stream;
determining, based on the second image frame, color information associated with the object;
adding the color information as color metadata to the first image stream;
encoding the first image stream; and
transmitting the encoded first image stream together with the color metadata, wherein the color metadata is included in a separate, dedicated metadata stream synched with the encoded first image stream.
