Answer: accumulated electrons that are ejected by the image sensor.

Explanation: photons hitting the CCD/CMOS are absorbed and free electrons (via the internal photoelectric effect) from the semiconductor. Those freed electrons are collected (accumulated) in each pixel's potential well and read out as the image signal.
