A semiconductor imaging sensor utilizes a color filter pattern. In addition to the at least one tool path, at least one collision contour is also defined. A compression ring is connected to an outside of the plastic body. The times by the clock are used in order to obtain traffic data by calculating, for example, the time spent on moving from one area to another. By forming the top layer in a PMOS process optimized for forming low-noise pixels, the pixel performance can be greatly improved, compared to using CMOS. The method is useful for passively detecting the presence of people, pets, or robots in proximity to a sensor.
