Abstract
A system for determining a distance to an object including a solid-state light source, a detector having a plurality of picture elements, and a processor to calculate the distance to the object as a function of exposure values generated by picture elements in response to the detected light. The picture elements generate exposure values by accumulating a first amount of electrical charge representative of reflected light during a first time window and a second electrical charge representative of reflected light during a second predetermined time window. The detecting occurs at the two charge storage wells; and the system interleaves the predetermined time windows with time windows during which the picture elements are used in a function different from the detecting and/or the picture elements include at least one further charge storage well to perform the function different from the detecting of the first and second amount of light.
