no. 1 Embodiment approach
[0035] Next, a first embodiment will be described with reference to the drawings.
[0036] The driving assistance device 1 is mounted on a vehicle, such as figure 1 Shown are an IR-LED 2 , cameras 3 and 5 , image pickup boards 4 and 6 , a head-up display device (hereinafter referred to as a HUD device) 7 , and a control section 8 .
[0037] The IR-LED 2 irradiates near-infrared light toward the face of a person sitting in the driver's seat of the vehicle (hereinafter referred to as the driver). Camera 3 is a near-infrared camera, which continuously photographs the driver's face. In addition, the image data obtained by imaging|photography by the camera 3 is called face image data hereinafter. In addition, the image acquisition board 4 temporarily stores the face image data acquired by the camera 3 .
[0038] The camera 5 continuously photographs the scenery ahead of the own vehicle (hereinafter also referred to as the foreground) that the driver can visually recognize throug...
no. 2 Embodiment approach
[0055] Next, a second embodiment will be described with reference to the drawings. In addition, in 2nd Embodiment, only the part which differs from 1st Embodiment is demonstrated.
[0056] The driving assistance device 1 of the second embodiment is the same as the first embodiment except that the display processing is changed and the display adjustment processing is added.
[0057] Furthermore, the display processing of the second embodiment is as follows Figure 5 In the illustration, the processing of S120 to S140 is omitted, and the processing of S210 to S240 is added, but it is the same as the first embodiment except that.
[0058] That is, in S110, when the indication sign F1 and the attention sign F2 are set (S110: YES), in S210, the moving object located ahead of the host vehicle is detected. Specifically, by obtaining an optical flow in image processing using foreground image data, an area moving independently of the host vehicle is extracted from the foreground imag...
no. 3 Embodiment approach
[0067] Next, a third embodiment will be described with reference to the drawings. In addition, in 3rd Embodiment, only the part which differs from 1st Embodiment is demonstrated.
[0068] The driving assistance device 1 of the third embodiment is the same as the first embodiment except that the display processing is changed and the display adjustment processing is added.
[0069] Furthermore, the display processing of the third embodiment is as follows Figure 7In the illustration, the processes of S120 to S140 are omitted, and the processes of S310 to S340 are added, and the process is the same as the first embodiment except that.
[0070] That is, in S110, when the display instruction flag F1 and the attention flag F2 are not set (S110: NO), the display process is temporarily terminated. On the other hand, in the case where the display indication flag F1 and the attention flag F2 are set (S110: Yes), at S310, for example, a saliency map (saliency map) is used (for example,...
