System and method for identifying speeding violations, comprising determining a current speed and a current location of a vehicle, determining a posted speed limit for the current location from a speed-by-street database, comparing the current speed of the vehicle to the posted speed limit, and evaluating whether the current speed exceeds the posted speed limit. Errors are identified in the speed-by-street database by storing a plurality of speeding violation records, wherein the speeding violation records each include a speeding event location; analyzing the speeding violation records to identify one or more speeding event locations having multiple speeding violations; comparing a posted speed limit at the one or more speeding event locations having multiple speeding violations to corresponding speed limit data in the speed-by-street database; and identifying one or more speed limit entries in the speed-by-street database that do not match the posted speed limit.

Each pixel cell (12) of an image sensor (10) is made of a 4-Tr structure, in which only one Tr for resetting a column (X) is so added to an ordinary 3-Tr APS as to reset only an arbitrary pixel selectively, thereby to confine the pixel size. When a pixel signal is to be read, the period, for which the pixel signals composing an ordinary image of one frame are read, is finely divided so that the pixel signals of the pixels receiving an ID light for the period are read out bit by bit and repeatedly. At this time, for only the column being read, an electric current is fed to a read amplifier in the pixel cell (12) or a variable gain amplifier in an output unit (14), thereby to suppress the power consumption. As a result, a lower power consumption and a higher pixel formation can be attained in an image pickup device for picking up an image and for acquiring the ID information of a light beacon existing in the image pickup range.
