Abstract
A camera system includes an image sensor and a processing apparatus receiving image frames from the sensor before and after receipt of a user picture signal. The processing apparatus discards frames that do not meet a quality criterion such as under-exposed frames. Also, the processing apparatus compresses only a subset of remaining frames, specifically, those that meet a compression amount threshold. The remaining frames are presented to a user, who can select a representative frame as the “picture” that was taken.
Claims20
A system comprising:
- one or more processors operatively coupled to an image sensor, said one or more processors operable to:
- receive image frames from said image sensor in response to receipt of a user picture signal,
- wherein said received image frames comprise a set of image frames captured by said image sensor prior to reception of said user picture signal, during said reception of said user picture signal, and after said reception of said user picture signal,
- wherein said image sensor starts capturing said image frames prior to said reception of said user picture signal based on receipt of a sensor input from a proximity sensor;
- discard a first set of image frames from said received image frames based on a determination that said first set of image frames do not satisfy a first predefined criterion;
- discard a second set of image frames from remaining image frames based on a determination that said second set of image frames do not satisfy a second predefined criterion different from said first predefined criterion;
- and
- compress one or more remaining image frames after discarding said second set of image frames.

An imaging system comprising:
- an image sensor operable to generate image frames,
- wherein said generated image frames comprise a set of image frames captured by said image sensor prior to reception of a user picture signal, during said reception of said user picture signal, and after said reception of said user picture signal,
- wherein said image sensor starts capturing said image frames prior to said reception of said user picture signal based on receipt of a sensor input from a proximity sensor;
- and
- a processing apparatus operable to:
- receive image frames from said image sensor in response to receipt of said user picture signal;
- discard a first set of image frames from said received image frames based on a determination that said first set of image frames do not satisfy a first predefined criterion;
- discard a second set of image frames from remaining image frames based on a determination that said second set of image frames do not satisfy a second predefined criterion different from said first predefined criterion;
- present one or more remaining image frames for selection after discarding said second set of image frames.
6 more elements
A system comprising:
- one or more processors operatively coupled to an image sensor, said one or more processors operable to:
- receive image frames from said image sensor in response to receipt of a user picture signal,
- wherein said received image frames comprise a set of image frames captured by said image sensor prior to reception of said user picture signal, during said reception of said user picture signal, and after said reception of said user picture signal,
- wherein said image frames captured by said image sensor prior to said reception of said user picture signal are based on receipt of a sensor input from a proximity sensor;
- discard a first set of one or more image frames from said received image frames based on a determination that said first set of one or more image frames do not satisfy at least one quality criterion;
- discard a second set of one or more image frames from remaining image frames based on a determination that said second set of one or more image frames do not compress to a size small enough to satisfy a compression threshold;
- and
- compress one or more remaining image frames after discarding said second set of one or more image frames.
