US 8,427,547 B1 · Camera with high-quality still capture during continuous video capture

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.

Dependent claims

An apparatus comprising:

a detector configured to generate a plurality of intermediate frames by processing a plurality of source frames, wherein said intermediate frames have an intermediate resolution;
a processor configured to (i) generate a plurality of video frames by compressing said intermediate frames while in a first state, wherein said video frames have a video resolution lower than said intermediate resolution, (ii) activate a capture operation while in a second state, wherein said capture operation buffers a particular frame of said intermediate frames and (iii) return to said first state in response to said activation of said capture operation.
