Abstract: A birds-eye-view image generation device includes a captured image acquisition unit, an image conversion unit, a birds-eye-view image combining unit, and a joint setting unit. The joint setting unit sets any position of a rim of a vehicle image corresponding to a vehicle included in the birds-eye-view image as an end point in an overlapping imaging range in two birds-eye-view images corresponding to two imaging devices of which imaging ranges overlap each other, and sets a line which extends in any direction on an opposite side to the vehicle image from the end point between two radial directions directed to the end point from the two imaging devices, as a joint which joins two birds-eye-view images which are combined.

Abstract: Provided is a drive assist display apparatus which displays a main view 20 showing an image of a wide backward area of the vehicle, and a sub view 21-3 showing a view point conversion image of a vicinity of the vehicle 1 as if looked down from a virtual viewpoint, the sub view 21-3 having a down side region where a thickness of the view point conversion image of the bumper 13 from the taken image is moderately represented and left and right side regions except the region of the bumper 13 where a taken image of an area around the vehicle is substantially shown, the sub view 21-3 formed as provided with a cutout section having a width corresponding to a width of the vehicle in accordance with a reduction scale of the view point conversion image, and the cutout section having sides rounded in form.

Abstract: Provided is a drive assist display apparatus which displays a main view 20showing an image of a wide backward area of the vehicle, and a sub view 21-4 showing a view point conversion image as if looked down from a virtual viewpoint to a vicinity of the vehicle 1, the sub view 21-4 having a down side region showing a moderate part of the bumper 13 and an up side region showing a subject in a distance area from the vehicle 1, and spread in form with increasing distance from a corresponding position of the vehicle 1.

Abstract: A drive assist display apparatus displays the backward or frontward of a vehicle. It is assumed that planes are perpendicular with the front-back direction, the downward, leftward and rightward directions being perpendicular with the front-back direction. Square subjects assumed to be on the planes are displayed as squares or rectangles having equal to one another on respective regions in accordance with the direction. The regions include a forward correction image display region in the vicinity of other display regions. The vicinity area has the same display image corresponding to a straight line coincident with a vertical straight line with respect to the ground surface or being in the vehicle front-back direction. The bottom side of a leftward or rightward correction image display region and the left or right side of a downward correction image display region are straight lines coincident with respective vehicle front-back direction straight lines.

Abstract: A method of generating an inverse conversion table generates an inverse conversion table T1 for generating from a viewpoint-converted image an image prior to viewpoint conversion processing relating to the viewpoint-converted image as an inversely converted image. A control unit 11 calculates the distance L(a,b) between a conversion reference coordinate P(a,b) stored in a table coordinate (a,b) of a viewpoint conversion table T2 and a calculation-target table coordinate (i,j) of an inverse conversion table T1 for each conversion reference coordinate, and calculates an inverse conversion reference coordinate A(i,j) which is stored in the calculation-target table coordinate (i,j) of the inverse conversion table T1 on the basis of the distance L(a,b) between the table coordinate (a,b) of the viewpoint conversion table T2 and the conversion reference coordinate stored in the table coordinate (a,b).

Abstract: Provided is a drive assist display apparatus which can realize, from imaging to displaying the front, left, right and down wide area of the backward or frontward of a vehicle, displaying in high visibility of a form of an imaged subject in accordance with purposes, improving visibility of directional and positional relationships between the imaged subject and the vehicle, and facilitating a movement of the eye line targeting to the subject on the display. It is assumed that planes are respectively perpendicular relationship with the vehicle front-back direction, the downward direction being vertically in perpendicular relationship with the vehicle front-back direction, the leftward direction being horizontally in perpendicular relationship with the vehicle front-back direction, and the rightward direction being horizontally in perpendicular relationship with the vehicle front-back direction.

Abstract: The present invention provides a drive assist display apparatus can make the line of sight easily change between the image views, and display the image views widely with suitable balance, for the purpose of the safety confirmation of backward or forward from a vehicle, and the purpose of the awareness of the limited area around the vehicle at the termination phase of the parking operation. The reference sign 10c indicates an image view showing a wide area behind the vehicle, the reference sign 11c indicates an image view showing an image converted from the image of the area behind the vehicle as if looked down from a virtual viewpoint, and the reference sign 13 indicates an image view drawn with pictures respectively connecting from the sides except the bottom side of the image view 11c to the corresponding sides of the clipped part of the image view 10c to be appeared as continuous from each side of the image view 11c to each side of the clipped part of the image view 10c.
