Systems and methods for imaging objects
View Patent ↗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.
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,
wherein the third portion of the period of time is subsequent to the second portion of the period of time, and wherein the second portion of the period of time is subsequent to the first portion of the period of time.
2. 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, determining whether the image is a color image or a black and white image; and adjusting, responsive to a determination that the image is the color image, at least one of a contrast of the image and a saturation of the image.
