Abstract

The invention provides an image processing method, an image processing device and an image processing system. The image processing method can detect detection objects such as nostrils of a driver and the like with high precision in a system using an on-vehicle camera as an example which is arranged on a vehicle and is used for shooting images of the face of the driver. The detection objects are diversified by various detection methods such as the following method and the like comprising the steps of: taking positions in a vertical direction during image shooting as candidates; detecting a plurality of positions; detecting the ranges of the candidates as the detection objects based on the brightness of pixels by aiming at pixel arrays arranged in a horizontal direction corresponding to each detected position respectively; and according to the lengths of the detected ranges, determining the detection objects from the candidates of the detection objects.

Description

[0001] This application is an invention patent application with the original application number 200580047809.9 (international application number: PCT / JP2005 / 002928, filing date: February 23, 2005, invention name: image processing method, image processing device, image processing system and computer program ) for a divisional application. [0002] technology area [0003] The present invention relates to an image processing method for detecting a specific detection object from a two-dimensional image obtained by arranging pixels in different first and second directions, an image processing device to which the image processing method is applied, and a The image processing system of the image processing device and the computer program for realizing the image processing device particularly relate to an image processing method, an image processing device, an image processing system and a computer program capable of improving the detection accuracy of a detection object.
