Imaging system

A non-transitory computer readable storage medium storing computer software code which when executing on a processor performs a method of imaging a scene, the method comprising:

• illuminating a scene;
• using a sensor to detect reflections from the scene in respect of each pattern of a sequence of patterns, wherein the sequence of patterns is configured to allow a first image of the scene having a first resolution to be constructed, wherein the first resolution is greater than the resolution of the sensor, and wherein the sequence of patterns includes a first sub-set of patterns, wherein the first sub-set of patterns is configured to allow a second image of the scene having a second resolution to be constructed, and wherein the second resolution is less than the first resolution;
• using detected reflections in respect of the patterns of the sequence to construct a first image of the scene having the first resolution;
• and
• using detected reflections in respect of the first sub-set of patterns to construct a second image of the scene having the second resolution.

An image processing system comprising:

• a processing circuit configured to control the system such that reflections from a scene are detected in respect of a sequence of patterns;
• and
• a processing circuit configured to receive information from a sensor that is configured to detect reflections from the scene in respect of each pattern of the sequence;
• wherein the sequence of patterns is configured to allow a first image of the scene having a first resolution to be constructed, wherein the first resolution is greater than the resolution of the sensor;
• wherein the sequence of patterns includes a first sub-set of patterns, wherein the first sub-set of patterns is configured to allow a second image of the scene having a second resolution to be constructed, and wherein the second resolution is less than the first resolution;
• and
• wherein the system further comprises a processing circuit configured to:
• use detected reflections in respect of the patterns of the sequence to construct a first image of the scene having the first resolution;
• and
• use detected reflections in respect of the first sub-set of patterns to construct a second image of the scene having the second resolution.

An imaging system comprising:

• one or more sources configured to illuminate a scene;
• and
• a sensor configured to detect reflections from the scene in respect of each pattern of a sequence of patterns;
• wherein the sequence of patterns is configured to allow a first image of the scene having a first resolution to be constructed, wherein the first resolution is greater than the resolution of the sensor;
• wherein the sequence of patterns includes a first sub-set of patterns, wherein the first sub-set of patterns is configured to allow a second image of the scene having a second resolution to be constructed, and wherein the second resolution is less than the first resolution;
• and
• wherein the system further comprises a processing circuit configured to:
• use detected reflections in respect of the patterns of the sequence to construct a first image of the scene having the first resolution;
• and
• use detected reflections in respect of the first sub-set of patterns to construct a second image of the scene having the second resolution.
