An information processing method for processing a file containing reversibly compressed or non-compressed digital image data obtained by digitally converting a signal that has been output from an image sensing device makes it possible to execute selectively signal processing of a plurality of types by using any of at least a plurality of types of luminance signal generating processing methods and/or a plurality of types of color signal generating processing methods for converting the digital image data contained in the file to data having a prescribed format. The method includes automatically selecting signal processing to be used from among the plurality of types of signal processing based upon information contained in the file, and causing the selected signal processing to be executed so that the digital image data contained in the file is converted to data having the prescribed format.

A signal processing method comprises the steps of: receiving an image frame including a plurality of rows of pixel data words, wherein each of the rows includes a start pixel data word and a plurality of successive pixel data words; processing each row by subtracting each successive pixel data word in the row from the start pixel data word in the row to produce a plurality of difference pixel data words; and storing and/or transmitting the difference pixel data words. An apparatus that performs the method is also included.

A method, system, and a computer program product that enables a second window opened on a display screen to "flow" into and fill/occupy all available space within the displayable area of the display screen without overlapping a first window occupying less than the maximum width and/or length of the display area. A window flowing utility enables multiple windows to concurrently coexist and fill the maximum displayable area of the display screen. The window flowing utility determines which areas of the display screen are not currently being utilized by the first window, and allows the second window to occupy all of the available space remaining on the display device surrounding the first window.

In one embodiment, video content is rendered within a windowpane displayed upon graphical user interface (GUI), a curser is positioned within the GUI responsive to user input, and a graphical resizing overlay is superimposed over the windowpane to facilitate arbitrary resizing of the windowpane and corresponding video content by the user when the cursor is positioned over the windowpane. In another aspect of the invention, an application window including at least a first windowpane and a second windowpane is displayed within a GUI, video content having a first display size is rendered within the first windowpane, the first windowpane and the corresponding video content is resized by a first amount resulting in a second display size, and the second windowpane is dynamically resized by a second amount proportional to the first amount such that the video content remains unobstructed by the first and second windowpanes and the application window.
