make all parallel lines (such as four horizontal edges of a cubic room) cross in one point. Perspective distortion occurs in photographs when the film plane is not parallel to lines that are required to be parallel in the photo. A common case is when a photo is taken of a tall building from ground level by tilting the camera backwards: the ...
The iPhone camera has come a long, long way since the phone was first introduced in 2007. However, there are still some things it can’t do all that well —. like, for instance, take vertical ...
Finally, we scale both images to the same approximate resolution and align the now horizontal epipoles for easier horizontal scanning for correspondences (row 4 of 2D image set). Note that it is possible to perform this and similar algorithms without having the camera parameter matrices M and M' . All that is required is a set of seven or more ...
A string, inside of the camera, hanging through a hole in the tripod screw, wound around a pulley inside the wooden box camera. To take a panoramic photo, the photographer swiveled the metal cap away from the lens to start the exposure. The rotation could be set for a full 360-degree view, producing an eighteen-inch-long negative. [24]
A flipped image is a static or moving image that is generated by a mirror-reversal of an original across a horizontal axis, making the image upside-down. In contrast, a flopped image is mirrored across the vertical axis, as in a conventional mirror image. [1]

Some display systems support multiple background layers that can be scrolled independently in horizontal and vertical directions and composited on one another, simulating a multiplane camera. On such a display system, a game can produce parallax by simply changing each layer's position by a different amount in the same direction.
The Dutch angle, also known as Dutch tilt, is a head tilt to one side, is a type of camera shot where the camera is set at an angle on its roll axis so that the shot is composed with vertical lines at an angle to the side of the frame, or so that the horizon line of the shot is not parallel with the bottom of the camera frame.
