Method and system for image construction using multiple exposures

An imaging system comprising:

• an image sensor configured to attain at least a first exposure and a second exposure during an exposure period;
• a movement sensor configured to sense movement of the imaging system, during the exposure period, in order to enable an amount of movement of the imaging system to be determined, relative to an initial position of the imaging system in the exposure period;
• and
• a processor configured to construct an image based on at least the first exposure and the second exposure, wherein the first exposure is attained during a first time period, within the exposure period, in which the determined amount of movement of the imaging system is within a predetermined movement range relative to the initial position of the imaging system, the second exposure is attained during a second time period, within the exposure period, in which the determined amount of movement of the imaging system is within the predetermined movement range relative to the initial position of the imaging system, and between the first time period and the second time period there is a third time period in which the determined amount of movement of the imaging system is outside the predetermined movement range relative to the initial position of the imaging system.

An imaging system, comprising:

A method for constructing an image, comprising:

• beginning an exposure cycle when a shutter button activation of an imaging system is detected;
• sensing movement of the imaging system during the exposure cycle for obtaining an amount of movement of the imaging system relative to an initial position of the imaging system;
• capturing a plurality of frames of a same scene during the exposure cycle;
• for each captured frame of the plurality of captured frames:
• determining whether a corresponding amount of movement of the imaging system during the capturing is within a predetermined movement range;
• responsive to a determination that the corresponding amount of movement is within the predetermined movement range, labeling the captured frame of the same scene with a first identifier, the first identifier indicating that the captured frame is not to be discarded;
• and
• responsive to a determination that the corresponding amount of movement is not within the predetermined movement range, labeling the captured frame of the same scene with a second identifier, the second identifier indicating that the captured frame is to be discarded;
• and
• constructing an image of the same scene based on at least one captured frame of the same scene that is labeled with the first identifier after discarding at least one captured frame of the same scene that is labeled with the second identifier.

• beginning an exposure cycle when a shutter button activation of an imaging system is detected;
• sensing movement of the imaging system during the exposure cycle for obtaining an amount of movement of the imaging system relative to a fixed reference point;
• controlling the imaging system such that an image sensor is effectively exposed when the amount of movement of the imaging system is within a predetermined movement range relative to the fixed reference point, the image sensor is not effectively exposed when the amount of movement of the imaging system is not within the predetermined movement range relative to the fixed reference point, and the image sensor is effectively re-exposed when the amount of movement of the imaging system is back within the predetermined movement range relative to the fixed reference point;
• and
• constructing an image based at least one exposure, each exposure obtained when the image sensor is one of exposed and re-exposed during the exposure cycle.
