Blind-spot image display system for vehicle, and blind-spot image display method for vehicle
First Claim
1. A blind-spot image display system for a vehicle, said blind-spot image display system comprising:
- a camera configured to capture surroundings of a vehicle, the surroundings being a blind spot from a driver;
a monitor set at a location in a cabin of the vehicle; and
an image processing controller configured to generate a monitor image signal for the monitor by image processing based on a real camera image signal inputted from the camera, the image processing controller including;
a blind-spot image formation unit configured to perform point-of-view conversion on the real camera image signal inputted from the camera into a blind-spot image that is viewed from a position of the driver'"'"'s point of view;
a vehicle cabin image formation unit configured to form a vehicle cabin image that is viewed from the position of the driver'"'"'s point of view;
a see-through display image generation unit configured to render the vehicle cabin image to be superimposed on the blind-spot image into a semi-transparent vehicle cabin image; and
an animation display image generation unit configured to generate an animation display image in which the vehicle cabin image to be superimposed on the blind-spot image is shifted stepwise from a non-transparent image to a see-through image;
wherein said camera, said monitor, and said image processing controller are configured and interconnected such that, upon starting an animation display, the animation display image generation unit generates a display image for the monitor by image composition on the blind-spot image which is acquired based on the real camera image signal inputted from the camera, and the vehicle cabin image which is shifted from a non-transparent image at start to a semi-transparent image stepwise by adding a preset transparency to a transparency of the vehicle cabin image for every elapse of a preset time.

Abstract
A see-through side view monitor system includes a camera, an external monitor, and an image processing controller having an image deformation unit configured to perform point-of-view conversion on a real camera image signal inputted from the camera into a blind-spot image that is viewed from the position of the driver'"'"'s point of view. A vehicle cabin image formation unit is configured to form a vehicle cabin image that is viewed from the position of the driver'"'"'s point of view. An image composition device is configured to generate a transparent display image showing a blind-spot image transmitted through a semi-see-through vehicle cabin image, and an image composition device is configured to generate an animation display image showing the blind-spot image to be shifted stepwise from the vehicle cabin image.

8. A blind-spot image display method for a vehicle, for displaying a blind-spot image on a monitor based on a real camera image signal inputted from a camera to capture surroundings of a vehicle, the surroundings being a blind spot from a driver, the method comprising:
-
a system activation operation procedure of performing system activation operation with an intention of displaying a blind-spot image to the monitor; an animation display procedure of displaying an animation image on the monitor, the animation display procedure being triggered by the system activation operation, the animation image showing a flow of the blind-spot images that appears stepwise with a passage of time, through a vehicle cabin image which is initially in a non-transparent state; an animation display image generation procedure of generating, upon starting an animation display, a display image for the monitor by image composition on the blind-spot image which is acquired based on the real camera image signal inputted from the camera, and the vehicle cabin image which is shifted from a non-transparent image at start to a semi-transparent image stepwise by adding a preset transparency to a transparency of the vehicle cabin image for every elapse of a preset time; and a see-through display procedure of displaying a see-through blind-spot image on the monitor, the see-through display procedure being triggered by a termination of the display of the animation image, the see-through blind-spot image being viewed from the position of the driver'"'"'s point of view through a semi-transparent vehicle cabin image.

9. A blind-spot image display system for a vehicle, said blind-spot image display system comprising:
-
a camera configured to capture surroundings of a vehicle, the surroundings being a blind spot from a driver; a monitor set at a location in a cabin of the vehicle; and an image processing controller configured to generate a monitor image signal for the monitor by image processing based on a real camera image signal inputted from the camera, the image processing controller including; a blind-spot image formation unit configured to perform point-of-view conversion on the real camera image signal inputted from the camera into a blind-spot image that is viewed from a position of the driver'"'"'s point of view; a vehicle cabin image formation unit configured to form a vehicle cabin image that is viewed from the position of the driver'"'"'s point of view; a see-through display image generation unit configured to render the vehicle cabin image to be superimposed on the blind-spot image into a semi-transparent vehicle cabin image; and an animation display image generation unit configured to generate an animation display image in which the vehicle cabin image to be superimposed on the blind-spot image is shifted stepwise from a non-transparent image to a see-through image; wherein the animation display image generation unit is configured to prepare a plurality of layers containing the vehicle cabin image and the blind-spot image, and to set, as a source image, a layer structure obtained by combining the layers stepwise, from the vehicle cabin image to the blind-spot image, and then upon starting an animation display, to generate a display image by image composition using varied transparencies for the respective layers, the display image being changed stepwise from a non-transparent vehicle cabin image at start to a blind-spot image seen through the vehicle cabin image.
