Patent ID: 8890887

Claim:
A method, comprising: displaying a plurality of related images at a same time; and synchronizing the related images such that a first operation directed by a user to a first image of the related images is performed on the first image and causes a second operation similar in visual effect to the first operation to be automatically performed on a second image of the related images, wherein the first operation is a first pan operation on the first image, the second operation is a second pan operation on the second image, the second pan operation is in a movement direction that is the same as that of the first pan operation, and the method further comprises automatically disabling the synchronizing, by stopping the second pan operation on the second image, when the first pan operation on the first image would cause a window, which contains the second image, to be more empty than a pan threshold amount, and wherein the disabling is performed by stopping the second pan operation on the second image while continuing the first pan operation directed by the user on the first image.
