Реферат: An apparatus for taking moving pictures, a method for taking moving pictures, and a novel pixel sensor array are disclosed. The apparatus includes a rectangular imaging array, a plurality of column processing circuits, and a controller. The rectangular imaging array is characterized by a plurality of rows and columns of UHDR pixel sensors and a plurality of readout lines, and a plurality of row select lines. Each column processing circuit is connected to a corresponding one of the plurality of readout lines. The controller causes the rectangular imaging array to measure a plurality of images of a scene that is illuminated by a pulsating light source characterized by an illumination period and a dark period. Each of the images is generated in a frame period which includes an exposure period and a dead period, the dead period being less than the dark period.
