Problems solved by technology

[0003] However, according to the conventional technology, the masking part is always superimposed on the combined part of the synthesized image in a certain display form
Thus, for example, when the vehicle user gets used to the display, the cover loses visibility, causing the warning to be less effective

Embodiment Construction

[0013] A specific example of a vehicle image display system capable of displaying a composite image of the vehicle's surroundings viewed downward from a virtual viewpoint above the vehicle according to an embodiment of the present invention will be described below. The vehicle image display system of the present invention includes capturing images in four directions around the vehicle by four on-board cameras of the vehicle, and displaying a plurality of monitoring images as monitored images on the display in the vehicle compartment while switching the images according to the operation of the vehicle user function. The vehicle image display system includes changing the viewpoint of the original image captured by the on-board camera into an overview image, and splicing the images to form a composite image that observes the surroundings of the vehicle from a virtual viewpoint above the vehicle, and then combining the composite image with the original image captured by the on-boar...

Abstract

When an image processing device subjects images photographed by on-vehicle cameras to viewpoint changing, and joints the images to form a top view image, and superposes masks on joints of the top view image to display it as an image to be monitored in a display, the masks of the top view image are highlighted until a passage of predetermined time after predetermined conditions are established. Thus, the masks can be made conspicuous only when necessary to be presented to an occupant of a vehicle, and an easily seen top view image can be displayed while preventing a reduction in effectiveness of warning of the masks.

Description

technical field [0001] The invention relates to a vehicle image display system and an image display method, which are used for splicing multiple images captured by multiple vehicle-mounted cameras to form a composite image, and then display the composite image on a display device in the vehicle compartment. Background technique [0002] A technology that has been widely used at present is to splice multiple images taken by multiple on-board cameras to form a composite image, and then display the composite image on the display device in the car to expand the driver's field of vision, thereby increasing the Safety of car driving. In many cases, the composite image formed by stitching multiple images cannot accurately reflect the actual environment due to the loss of image continuity at the junction. In these cases, a method such as that disclosed in Japanese Patent Laid-Open Application No. 2003-67735 provides a warning to the user of the vehicle by masking the image joint to...
