Abstract
A method of detecting light-emitting diode (LED) light starts with a control circuitry generating a shutter signal that is transmitted to a pixel array to control image acquisition by the pixel array and to establish a set exposure time. The readout circuitry may then read out the image data from the pixel array that includes reading out the image data from a plurality of successive and overlapped frames having the set exposure time. The set exposure time may be the same for each of the frames. The successive and overlapped frames may be interlaced frames. Other embodiments are also described.
Claims26
A method of detecting a light emitting diode (LED) by an imaging system comprising:
- generating a shutter signal by a control circuitry that is transmitted to a pixel array to control image acquisition by the pixel array and to establish a set exposure time;
- and
- reading out by the readout circuitry image data from the pixel array that includes reading out the image data from a plurality of successive and overlapped frames having the set exposure time, wherein the set exposure time is the same for each of the frames.
A method of detecting a light emitting diode (LED) by an imaging system comprising:
- simultaneously enabling all pixels within a pixel array to simultaneously capture image data during a single acquisition window;
- and
- reading out image data from a pixel array that includes reading out the image data from a plurality of successive and interlaced frames having a same exposure time.
An imaging system to detect a light emitting diode (LED) comprising:
- a pixel array for acquiring image data, the pixel array including a plurality of rows and columns;
- and
- a readout circuitry coupled to the color pixel array to readout image data from the pixel array that includes reading out the image data from a plurality of successive and interlaced frames having a same exposure time.
