  • Patent number: 8717324
    Abstract: Methods (1000), apparatuses (100), and computer readable storage mediums for interfacing with a multi-point input display device (181, 204, 304) are disclosed. A visual object is displayed (1010) on a multi-point input display device (181, 204, 304). The position of a first input contacting the multi-point input display device (181, 204, 304) is detected (1020). At least the displayed visual object is selected (1030) based on the position of the first input. The position of a second input contacting the multi-point input display device (181, 204, 304) is detected (1040) contemporaneously with the first input. A separation line across the visual object is determined (1050) so as to define a first portion and a second portion of the visual object. A change in the position of the second input is identified (1060). A change in a display characteristic of the first portion relative to the second portion is controlled (1070) in accordance with the identified change in the position of the second input.

  • Publication number: 20120213445
    Abstract: A method of rating a captured image is disclosed. A database of reference images is accessed. One or more of the reference images has an associated rating value. One or more of the reference images is selected to form at least one subset of reference images based on metadata associated with the reference images. The reference images of the subset are captured approximate to a capture location of the captured image and at a time associated with a capture time of the captured image. One or more similar reference images are determined from the selected subset based on at least one characteristic of the captured image. The captured image is rated based on the rating values associated with the similar reference images.
