Abstract: A method for detecting a defective image of the present invention includes obtaining an edge image by performing an edge tracking process on an original image, detecting an isolation point whose size is equal to or smaller than a predetermined size from a processed image obtained by performing an erosion process after an expansion process on the edge image, and detecting a defective image in the original image based on the isolation point.

Abstract: An image processing method of the invention includes changing tone values of peripheral pixels by performing a filtering process in respect to the peripheral pixels around a pixel of interest, after determining the pixel of interest; and changing a tone value of the pixel of interest, based on the peripheral pixels that have been filter processed.

Abstract: A hand-held device for reducing the size of food items, for example by slicing or grating. The disclosed device has a slicing drum transversally inserted into an aperture on a lateral wall of a casing. Preferably, both the drum and its size reducing members, such as blades, are removable. Ideally, the drum can be inserted in an aperture on either of two opposing lateral walls so that the device may be easily used by both right-handed and left-handed people. A slicing compartment is formed by the casing and the slicing drum. A grip handle extends from the casing and preferably has an arm cover, which may open to a storage receptacle intended for storage of additional blades. The slicing drum is engaged with a crank lever assembly for rotation. A distal wall of the casing is preferably curved to form a tangential relationship with the slicing drum to, along with gravitational force, advance a food item to be reduced in size.

Abstract: An interrupt controller can execute a faster interrupt service routine after an occurrence of the interrupt by writing branch instructions upon initialization of the computer environment in advance of the actual interrupt. The interrupt controller includes an interrupt mask register that receives, and stores an interrupt on/off instruction from a CPU. An interrupt priority register receives and stores an interrupt priority instruction from the CPU. An interrupt mask circuit unit selectively receives and forwards an interrupt generating signal from peripheral devices in response to an interrupt on/off instruction from the interrupt mask register. A priority determining circuit unit receives the interrupt generating signals from the interrupt mask circuit unit, determines priorities of the interrupt signals in response to the interrupt priority instruction from the interrupt priority register, and forwards an interrupt priority signal to an interrupt terminal of the CPU.

Abstract: The present invention relates to a register file in a microprocessor and operating system thereof for performing a data transfer between register cells within a register file. The register file has a plurality of register cells and an internal common bus that can directly transfer data between register cells by binding together control units for feedback transmission in each register cell to perform a direct data transfer between register cells. Each of the registers cell includes a repeater cell, a data input control unit, a data transfer control unit and a feedback transmission control unit.
