Embodiment approach 1

[0073] figure 1 It is a block diagram of a configuration example of the image processing system in Embodiment 1 of the present invention. exist figure 1 1 in the vehicle is an imaging device such as a vehicle-mounted camera installed in a vehicle. The imaging device 1 communicates with a communication network such as an in-vehicle LAN (Local Area Network) such as a communication line such as a dedicated cable, or a wired or wireless network, and performs image processing for image processing. Device 2 is connected. The imaging device 1 is arranged in front of the driver such as handles and instrument panels in the vehicle, and can adjust the shooting state so that the horizontal and vertical directions of the driver's face become horizontal or vertical.

[0074] The imaging device 1 includes: an MPU (Micro Processer Unit) 11 for controlling the whole of the device, a ROM (Read Only Memory) 12 for recording various computer programs and data executed based on the control of t...

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.
