... of the chosen display, the origi- nal aspect ratio of movies usually varies between 1.33:1 and 2.40:1. The common solutions to viewing content in an as- pect ratio different from that of the display device are either to squeeze the image onto the screen ( Fig. 1 (a)), to crop the image ( Fig. 1 (b)) such that only a central area is visible, or to horizontally ( Fig. 1 (c)) or vertically ( Fig. 1 (d)) pad the images with black borders (letterboxing/pillarboxing). Squeezing the images leads to distorted images which can be disturbing and is unacceptable in most cases (cp. ...

Squeezing the images leads to distorted images which can be disturbing and is unacceptable in most cases (cp. Fig. 1 (a)). Padding the images leaves large portions of the display unused and thus makes the image smaller which is particularly annoying on mobile devices (cp. Fig. 1 (c), (d)). Cropping the image may lead to loss of important details of a movie, because up to 50% of the original picture can be lost (cp. Fig. 1 (b), where half of a main actor ...
