Abstract: A method and apparatus for resizing or processing images initially retrieves a one-dimensional sample of the image, such as a line of pixels. The image can be of a machine-readable symbol, or other data. A moving window having, for example, five pixels, includes a center "hard core" and four surrounding pixels. Two or more structural sets or multisets are applied to the window to produce a set of pixels greater than the set of pixels in the original image. For example, the center pixel is repeated three times, while immediately adjacent left and right pixels are repeated twice. Thus, a series of nine pixels results. The resulting nine pixels are then sorted based on descending gray scale levels. The n-th largest pixels is selected, such as the third largest. The image is updated, the window moved, and the method repeats again. Pyramid filtering, cubic convolution interpolation, or other techniques can be used to reduce the size of an image, and more complex windows and structural sets can be employed.

Abstract: An image input section 1530 of a storage medium issuing system inputs image information and an image processing unit 420 performs image processing for the image information input through the image input section 1530. The image information processed by the image processing section is stored on a storage medium by an image write section 1500.When the storage medium on which the image information is stored is inserted into a gaming machine, the image information is read by a read section of the gaming machine. A game execution section of the gaming machine executes a predetermined game in accordance with image information concerning the game stored in a game image storage section. A display control section controls display of the image information read from the storage medium instead of reading a specific symbol among the image information stored in the game image storage section.

Abstract: The present invention is a method for chemical-mechanical planarization of semiconductor wafers that is highly useful for planarizing stop-on-feature design wafers. Initially, the wafer is positioned against a liquid solution over a planarizing surface of a polishing pad. At least one of the wafer or the pad is moved with respect to the other at a relatively low velocity to maintain a substantially continuous film of liquid solution between the wafer and the pad. The temperature of a pad platen is also controlled to maintain a relatively low temperature of the liquid solution at which the solution is highly selective to a layer of material on the wafer.

In operation, heat from the platen and polishing pad flows through the thermal conductors to reduce temperature gradients across the planarizing surface of the polishing pad.
