An image signal storing unit stores an image signal provided from the outside. An image processing unit appropriately processes the image signal stored in the image signal storing unit in accordance with the instruction from an adjusting unit. A projecting unit projects, onto a display area, light corresponding to an image created by the image processing unit. A display size determination unit computes the display size of the picture plane displayed on a screen based on an image captured by the camera provided adjacent to the projection-type video-image display device. The display size determination unit then determines whether or not the display size of the picture plane is equal to or larger than a predetermined upper-limit size.

The invention discloses a monocular panoramic parking calibration method, and relates to the technical field of conversion from camera images to aerial views. The essence of the aerial views is that information in an image plane is re-projected to a ground plane. Since projection is needed, a projection conversion relation H between the two planes needs to be known firstly; in a traditional method, a calibration canvas image is placed on the ground plane, the size and the number of black and white grids of a canvas are fixed, the placing position of the canvas is fixed, and then coordinates of four vertexes of the calibration canvas on the ground plane are obtained. However, in the traditional method, the placing position of the square canvas is fixed, and for ordinary users, great difficulty exists actually because subjective deviation certainly exists. However, according to the method, subjective deviation of a common user is received, the calibration canvas may not be completely fixed to be placed, the objective behavior of people is met, the calibration using efficiency is improved, and the manpower and material resource cost is saved.
