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.
