Abstract

Even if a problem has occurred with respect to a multimedia micro-computer that generates a composite image including guiding lines, while a gearshift of a vehicle is in reverse, a reset process is not performed for the multimedia micro-computer. The reset process is performed after the gearshift is determined to have moved from reverse.

Claims

1. An image processing apparatus that processes images, the image processing apparatus comprising:

a shift position sensor that detects a position of a gearshift for gear change of a vehicle on which the image processing apparatus is mounted, and outputs a shift signal;

a camera mounted on the vehicle and that captures an image of an object in a surrounding of the vehicle and generates an image signal;

an image processor that receives the image signal from the camera and that outputs the acquired captured image represented by the image signal to a display when the image processor determines that the shift signal output by the shift position sensor indicates that the position of the gearshift is a predetermined position;

a first micro-computer that controls the image processor and that combines the captured image with a diagram to create a composite image that the first micro-computer supplies to the image processor for output by the image processor to the display;

the image processor detecting whether a problem exists in the first micro-computer based on the composite image supplied to the image processor from the first micro-computer; and

a second micro-computer that performs a reset process of the first micro-computer when the image processor has detected that the problem exists with respect to the first micro-computer, wherein

when the image processor has detected the problem with respect to the first micro-computer while the position of the gearshift is determined to be the predetermined position, (i) the second micro-computer does not perform the reset process of the first micro-computer while the position of the gearshift remains the predetermined position and the image processor continuously outputs the acquired captured image without the diagram to the display while the position of the gearshift remains the predetermined position, and (ii) the second micro-computer performs the reset process after the position of the gearshift is determined to have changed from the predetermined position.

2. The image processing apparatus according to claim 1, wherein

the predetermined position of the gearshift is a reverse position.

3. The image processing apparatus according to claim 1, wherein

the image processor provides a notification to a user, during a time period from a first time point at which the image processor has detected the problem to a second time point at which the second micro-computer performs the reset process, that the reset process will be performed.

4. The image processing apparatus according to claim 1, wherein

the image processor determines, based on the shift signal, a control gearshift position of the gearshift of the vehicle, after a predetermined time period has passed from a change of the shift signal, and when the shift signal is changed during the reset process, the image processor determines the control gearshift position after the reset process ends, regardless of progress of the predetermined time period.

5. An image processing method of processing images, the image processing method comprising the steps of:

(a) detecting a position of a gearshift for gear change of a vehicle based on a shift signal output by a shift position sensor of the vehicle;

(b) receiving, by an image processor, an image signal generated by a camera mounted on the vehicle, the image signal representing a captured image of an object in surroundings of the vehicle, the image processor outputting the acquired captured image to a display of the vehicle when the image processor determines that the shift signal output by the shift position sensor indicates that the position of the gearshift is a predetermined position;

(c) combining, by a first micro-computer that controls the image processor, the captured image with a diagram to create a composite image that the first micro-computer supplies to the image processor for output by the image processor to the display;

(d) detecting, by the image processor, whether a problem exists in the first micro-computer based on the composite image supplied to the image processor from the first micro-computer; and

(e) performing, by a second micro-computer, a reset process of the first micro-computer when the step (d) has detected that the problem exists with respect to the first micro-computer, wherein

when the step (d) has detected the problem with respect to the first micro-computer while the position of the gearshift is determined to be the predetermined position, the step (e) does not perform the reset process of the first micro-computer while the position of the gearshift remains the predetermined position and the image processor continuously outputs the acquired captured image without the diagram to the display while the position of the gearshift remains the predetermined position, and the step (e) performs the reset process after the position of the gearshift is determined to have changed from the predetermined position.

6. The image processing method according to claim 5, wherein

the predetermined position of the gearshift is a reverse position.

7. The image processing method according to claim 5, further comprising the step of:

(f) notifying a user, during a time period from a first time point at which the step (d) detected the problem to a second time point at which the step (e) performs the reset process, that the reset process will be performed.

8. The image processing method according to claim 5, wherein

the step (a) determines, based on the shift signal, a control gearshift position of the gearshift of the vehicle, after a predetermined time period has passed from a change of the shift signal, and when the shift signal is changed during the reset process, the image processor determines the control gearshift position after the reset process ends, regardless of progress of the predetermined time period.
