A detection system detects an occurred event at a plurality of positions with high accuracy. The detection system includes a plurality of cameras, each of which performs detection processing to output detection information, a network that transmits pieces of detection information from the plurality of cameras and a system control unit that provides notification of occurrence of a predetermined event on the basis of the pieces of detection information from the plurality of cameras. Each of the plurality of cameras includes an image capturing element that captures an image of a target object, and generates image-data frames that time-sequentially line up and a detection frame determination unit that determines relationship between the target object and a predetermined detection frame, and generates a result of the determination as the detection information.

An image processing apparatus, an image processing system and an image processing method can correct the distortion of an image at a low cost and can generate a high quality image in real time. An image processing apparatus is provided which is an image processing apparatus for correcting an original image having distortion. The apparatus includes a horizontal one-dimensional interpolating unit () for correcting the distortion in the horizontal direction by performing a one-dimensional interpolation operation using a horizontal correcting parameter Xm which indicates a correction quantity in the horizontal direction at a pixel point constituting the original image, and a vertical one-dimensional interpolating unit () for correcting the distortion of the original image in the vertical direction by performing the one-dimensional interpolation operation to the image obtained by the correction by the horizontal one-dimensional interpolating unit (), using a vertical correcting parameter Ym which indicates a correction quantity in the vertical direction at the pixel point constituting the original image.

A lattice dividing unit determines lattice lines to divide parameters of all points of a picture at every division and supplies distortion correction parameters (distortion correction coordinates) on the lattice points to a distortion correction memory (not shown). A polynomial of degree n coefficient deriving unit expresses all distortion correction coordinates on each lattice line in the form of a function relative to positions on lattice lines and approximates the distortion correction coordinates by desired division polynomial of degree n. Further, a sample point deriving unit compresses distortion correction parameters based upon the division polynomial of degree n obtained from the polynomial of degree n coefficient deriving unit. In the derived division polynomial of degree n, internal points which result from dividing both ends of the division polynomial of degree n by n is supplied to the distortion correction memory as new distortion correction parameters (approximated distortion correction coordinates). Thus, a memory capacity of a required memory can be reduced in the image processing for correcting distortion of an image.
