A pixel of an electrophoretic display is driven from one extreme optical state to a second optical state different from the one extreme optical state by applying to the pixel a first drive pulse of one polarity; and thereafter applying to the pixel a second drive pulse of the opposite polarity, the second drive pulse being effective to drive the pixel to the second optical state.

In an image sequence stabilization method and a camera, a sequence of input digital images are captured. The sequence of input digital images is replicated to provide a corresponding sequence of archival images and a corresponding sequence of display images. The archival image sequence is automatically stabilized to provide a stabilized archival image sequence. The display image sequence is automatically stabilized to provide a stabilized display image sequence. The stabilization methods used for the two sequences are different, although both can be digital.

The invention discloses a photographic system, which is operated in a photographic device with a proximity sensor. The proximity sensor senses an approach distance between a user and the proximity sensor in real time. The system comprises an acquisition module, a judgment module and a triggering module, wherein the acquisition module is used for acquiring the sensed approach distance between the user and the proximity sensor in real time; the judgment module is used for judging whether the acquired approach distance is shorter than a preset effective photographic distance of the photographic device or not; and the triggering module is used for triggering the photographic device to take a photo if the acquired approach distance is shorter than the effective photographic distance. The invention also provides a photographic method. By the photographic system and the photographic method, the user can be prevented from taking blurred photos due to photographic device shake caused by the pressing of a shutter when taking the photo.
