Embodiment Construction

[0029] A facial image detection device according to an embodiment of the present disclosure will be described with reference to the drawings. According to this embodiment, figure 1 The configuration of face image detection device 1 in a vehicle is shown. The facial image detection device 1 includes a main control circuit 2 connected to an ambient light detection part 3 , a light projector 4 , an image capture part 5 and a manipulation part 6 . The facial image detection device 1 can be communicably connected with the navigation device 11 through a local area network (LAN) 15 .

[0030] The main control circuit 2 is configured like computer hardware including a CPU, ROM, RAM, and peripheral circuits such as AD converter circuits and input / output circuits according to well-known techniques. The CPU executes control programs and data stored in the ROM to provide various functions of the facial image detection device 1 . The main control circuit 2 includes an operation mode det...

Abstract

The invention provides a face image detection apparatus. An in-vehicle face image detection apparatus (1) operates as follows. A projector (4) projects light. A capture controller (24) settles a capturing condition to capture a predetermined region including a face of an occupant. A capturing portion (5) captures the predetermined region based on the capturing condition. An environment light detection portion (3) detects environment light radiated to the vehicle or occupant. An operation mode determination portion (21) determines a first mode where intensity of the environment light is greater than a threshold or a second mode where the intensity is not greater than the threshold. A light emission pattern setup portion (22) settles a light emission pattern for a light source of the projector based on the operation mode. A projector controller (23) controls the projector to activate the light source based on the light emission pattern.

Description

technical field [0001] The present disclosure relates to a face image detection device that detects a human face image in a captured image. Background technique [0002] Patent Document 1: JP H08-159733A [0003] Patent Document 2: JP H09-021611A (US 5801763) [0004] Patent Document 3: JP 2005-301742A (US 2005 / 0226472) [0005] Patent Document 4: JP 2005-354155A (US 2005 / 0270413) [0006] Patent Document 5: JP 2010-176382A [0007] According to the disclosed driver state detection apparatus, the camera device provided in the compartment captures the driver's face. The device processes captured facial images and extracts feature points of the face, such as eyes, nose, and mouth. Based on feature point positions or states of opening or closing of eyes, the device detects driving states such as driver's face orientation and fatigued driving. The driver status detection device uses an infrared flash or LED to illuminate and capture the driver's face. An infrared flash or...
