Abstract
A method for processing a source frame is disclosed. The method generally includes the steps of (A) generating an intermediate frame by digitally processing the source frame, wherein the intermediate frame has an intermediate resolution and has an intermediate color space, (B) generating a video frame by down-sampling the intermediate frame, wherein the video frame has a video resolution lower than the intermediate resolution and has a video color space different than the intermediate color space, (C) generating a video stream by compressing the video frame with a video encoding technique and (D) generating a still picture by formatting the intermediate frame with a picture formatting technique, wherein (i) the still picture has the intermediate resolution and (ii) generating the still picture occurs substantially simultaneously with generating the video stream.
