Abstract

An image storage system suitable for use with devices for detecting/recording overspeedily vehicles. The system includes at least one image sensor (11, 15, 53, 55) for generating data representing an image applied to the sensor. The system includes means for applying a first image (10, 54) to the sensor (11, 53) for generating first data representing at least relatively coarse features in the first image, and means for applying a second image (14 56) including an enlarged portion of the first image to the sensor (15, 55) for generating second data representing at least relatively fine features in tire first image. The second data representing relatively fine features has a set level of definition. The first data representing relatively coarse features has a level of definition which is below the set level. The quantity of data is thereby reduced for storage purposes. A data storage system including a frame grabber (19) and digital computer (20) having a hard disk is also disclosed.
