With growing mobile data consumption, foldable displays have enabled further enlargement for the display of a mobile device without increasing the size and weight of the device. This paper addresses a possible problem of image distortion for image displays on foldable mobile devices. When a mobile device is folded with a certain degree, the part of a displayed image in the folded area (or bending zone) of the device may be squeezed. To provide better visual quality for a foldable display, we formulate the problem as a piecewise content-aware image retargeting problem. To compensate the squeezed region of an image in the bending zone of a device, we propose to expand this region toward the left and right sides, respectively, based on the image content. In the meantime, the original left and right regions of the image should be also adjusted accordingly. In this paper, we investigate how to apply an image retargeting technique to solve the problem for better identifying visually significant contents of the image and produce more pleasing display result.
