Abstract
The disclosure relates and extends to a light source having a strobing or pulsing sequence suitable for use with a CMOS sensor that does not require, have, or use a global shutter. Instead, the CMOS sensor synchronizes the strobing input with the blanking portion of the sensor readout pattern and disables the strobing during sensor readout, or when the strobing would otherwise leave artifacts in the image. The CMOS sensor freezes its readout during the strobing.
Claims21
1-25. (canceled)
A system comprising:
- an image sensor comprising a pixel array, wherein the pixel array is read out during a readout period;
- a light source capable of strobing light at a strobing frequency;
- and
- a control unit in communication with the image sensor and the light source for synchronizing operations of the image sensor and the light source;
- wherein the image sensor and the light source are synchronized such that the light source does not emit light when active pixels in the pixel array are read.
