摘要： A relatively rapidly moving object is imaged with a sensor incorporating a rolling electronic shutter, while using flash illumination which is comparable to or dimmer than ambient light. This is achieved by utilizing a physical shutter between the object and sensor which is synchronized to the flash. Preferably, the physical shutter is also operated so as to be open for a time interval which is coextensive with the presence of the flash. Preferably, an optical mechanism is provided between the object and sensor which causes the image to be focused when the light is flashed and blurred otherwise. Preferably, an optical filter is positioned between the object and sensor, and this filter is constructed to transmit to the CMOS sensor light at the wavelength of the flashing light source but to attenuate ambient light.
