SYSTEMS AND METHODS FOR IMAGING OBJECTS
First Claim
1. An imaging device, comprising:
- a sensor configured to provide an image of an object, the sensor having a sensor exposure time and a sensor gain and the image including a plurality of frames, each of the plurality of frames depicting at least a portion of the object;
a motion detector to determine whether there is movement of the at least a portion of the object between adjacent frames of the plurality of frames;
a controller configured to set the sensor exposure time to a first value in response to a determination by the motion detector that there is movement of the at least a portion of the object between adjacent frames, and to set the sensor exposure time to a second value that is substantially different than the first value in response to a determination that there is no movement of the at least a portion of the object between adjacent frames;
the controller further being configured to adjust at least one of the sensor exposure time and the sensor gain to substantially maintain a luminance value of the plurality of frames at a target luminance value irrespective of whether the motion detector determines that there is movement of the at least a portion of the object between adjacent frames or not.

Abstract
Systems and methods for imaging objects are provided. An imaging device includes a sensor to provide an image of an object. The sensor can have a sensor exposure time and a sensor gain and the image includes a plurality of frames, each of the plurality of frames that can depict at least a portion of the object. The imaging device includes a motion detector to determine whether there is movement of the at least a portion of the object between adjacent frames of the plurality of frames. The imaging device also includes a controller. The controller can set the sensor exposure time to a first value in response to a determination by the motion detector that there is movement of the at least a portion of the object between adjacent frames. The controller can also set the sensor exposure time to a second value in response to a determination that there is no movement of the at least a portion of the object between adjacent frames. The controller can also adjust the sensor exposure time, the sensor gain, or both to maintain a luminance value of the plurality of frames at a target luminance value.

18. A method of imaging objects, comprising acts of:
-
generating an image of an object using a sensor, the image including a plurality of frames depicting at least a portion of the object; determining whether there is movement between of the at least a portion of the object between adjacent frames of the plurality of frames; setting, responsive to the act of determining, a sensor exposure time of the sensor to a first value when movement of the at least a portion of the object between adjacent frames is determined and setting the sensor exposure time of the sensor to a second value that is substantially different than the first value when no movement of the at least a portion of the object between adjacent frames is determined; and adjusting at least one of the sensor exposure time and a sensor gain of the sensor to substantially maintain a luminance value of the plurality of frames at a target luminance value irrespective of whether movement of the at least a portion of the object between adjacent frames is determined or not. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A computer readable medium encoded with instructions for execution on a processor, the instructions when executed, performing a method comprising acts of:
-
generating an image of an object using a sensor, the image including a plurality of frames depicting at least a portion of the object; determining whether there is movement between of the at least a portion of the object between adjacent frames of the plurality of frames; setting, responsive to the act of determining, a sensor exposure time of the sensor to a first value when movement of the at least a portion of the object between adjacent frames is determined and setting the sensor exposure time of the sensor to a second value that is substantially different than the first value when no movement of the at least a portion of the object between adjacent frames is determined; and adjusting at least one of the sensor exposure time and a sensor gain of the sensor to substantially maintain a luminance value of the plurality of frames at a target luminance value irrespective of whether movement of the at least a portion of the object between adjacent frames is determined or not.
