Abstract

A drive assist devices include a display that displays an image around a vehicle imaged by an imaging device installed on the vehicle, a setting unit that sets a target designated by a user on the image as a recognition target, a detection unit that detects a state change of the recognition target on the image in a case where the recognition target is set, and a notification control unit that controls a notification device to notify the user of the detection result in a case where the state change of the set recognition target is detected.

Claims

1. A drive assist device comprising:

a display unit that displays an image around a vehicle imaged by an imaging device installed on the vehicle;

a setting unit that sets a target designated by a user on the image as a recognition target;

a detection unit that detects a state change of the recognition target on the image when the recognition target is set; and

a notification control unit that controls a notification device to notify the user of the detection result when the state change of the recognition target is detected.

2. The drive assist device according to claim 1,

wherein the recognition target is a signal of traffic light, and

wherein the detection unit detects the state change of the traffic light from a stop signal to a go signal.

3. The drive assist device according to claim 1,

wherein the recognition target is a preceding vehicle, and

wherein the detection unit detects the state change of the preceding vehicle from a stopped state to a starting state.

4. The drive assist device according to claim 1, further comprising:

a conversion unit that converts a position on a first image suitable for visually checking the recognition target imaged by the imaging device to a position corresponding to a position on a second image suitable for detecting the state change of the recognition target imaged by another imaging device installed on the vehicle,

wherein the display unit displays the first image,

wherein the setting unit sets the target designated by the user on the first image as a recognition target on the second image, and

wherein, in a case where the recognition target is set, the detection unit detects the state change of the recognition target on the second image.

5. The drive assist device according to claim 1, further comprising:

a speed detection unit that detects a moving speed of the vehicle,

wherein, in a case where the moving speed exceeds a threshold value, the display unit does not display the image.
