Abstract
An adaptive camera resolution system is described for use with matching resolution with compression. In one example, the a method includes capturing a first set of frames of a video sequence at an image sensor at a first resolution, capturing a second set of frames of the video sequence at the image sensor at a second lower resolution, wherein the first and second sets of frames are interleaved, receiving the captured frames at a video encoder, and combining the frames at the video encoder to generate an encoded video sequence of frames with the first resolution.

A method comprising:
- capturing a first set of frames, including I frames, of a video sequence at an image sensor at a first resolution;
- capturing a second set of frames of the video sequence at the image sensor including capturing referenced B frames at a second resolution lower than the first resolution and capturing non-referenced B frames at a resolution lower than the second resolution, wherein the first set of frames and the second set of frames are interleaved;
- receiving the captured first set of frames and the second set of frames at a video encoder;
- and
- combining the first set of frames and the second set of frames at the video encoder to generate an encoded video sequence of frames with the first resolution.
An apparatus comprising:
- an image sensor to capture a first set of frames, including I frames, of a video sequence at a first resolution and to capture a second set of frames of the video sequence including capturing referenced B frames at a second resolution lower than the first resolution and capturing non-referenced B frames at a resolution lower than the second resolution, wherein the first set of frames and the second set of frames are interleaved;
- an image input interface to receive the captured first set of frames and second set of frames from the image sensor;
- and
- a video encoder to receive the captured first set of frames and second set of frames from the image input interface and to combine the frames to generate an encoded video sequence of frames with the first resolution.
A portable device comprising:
- a display to show an encoded video;
- an image sensor to capture a first set of frames, including I frames, of a video sequence at a first resolution and to capture a second set of frames of the video sequence including capturing referenced B frames at a second resolution, lower than the first resolution and capturing non-referenced B-frames at a resolution lower than the second resolution, wherein the first set of frames and the second set of frames are interleaved;
- an image input interface to receive the captured first set of frames and second set of frames from the image sensor;
- and
- a video encoder to receive the captured first set of frames and second set of frames from the image input interface and to combine the frames to generate the encoded video as a sequence of frames with the first resolution to show on the display.
