Abstract
A system for synchronizing image capture and a light source has a first strobing light emitting diode (LED) array with a plurality of LEDs located to light an illumination area. The LED array has an on cycle during which the LED array is activated and an off cycle during which the LED array is inactivated. The system also has a camera located with a view of the illumination area. The camera has an image exposure that coincides with the on cycle of the strobing LED array.
Claims14
A system for synchronizing image capture and a light source comprising:
- a first strobing light emitting diode (LED) array comprising a plurality of LEDs located to light an illumination area, the LED array having an on cycle during which the LED array is activated and an off cycle during which the LED array is inactivated, wherein the strobing LED array provides apparently constant human observable illumination of the illumination area;
- and
- a camera located with a view of the illumination area, the camera having an image exposure that coincides with the on cycle of the strobing LED array.
A scanning system comprising:
- a conveyor that conveys an object through an illumination area that is stationary relative to the object;
- a strobing light source that illuminates at least the illumination area so that the illumination appears constantly illuminated to the human eye;
- and
- a camera located with a view of the illumination area, the camera having an image exposure that coincides with an on cycle of the strobing light source.
