摘要： Techniques for displaying contextual information in clipped views of two-dimensional workspaces are provided. A method for indicating an object includes: providing a workspace having a viewed space and a populated space, the viewed space being delineated by a border; determining an object in the populated space; determining a direction of the object from the viewed space; and indicating the object with an indicator on the border of the viewed space in the direction of the object. The distance of the object may determine the appearance of the indicator. The indicator may also show a user's interest. An object indicating system includes: an object determination circuit that determines an object in a populated space and a direction of the object from a viewed space; and an indicator mapping block that indicates the object with an indicator on a border of the viewed space in the direction of the object.

摘要： A method for dynamic range adjustment of image data of a captured image by determining a white point of an image. The method also involves determining a black point of the image, classifying pixels of the image, and determining an offset value for a pixel of the image based on the determined black point of the image and the determined classification of the pixel. Dynamic range adjustment of the image data is performed using the determined offset value for the pixels of the image and the determined white point of the image.
