Abstract: The debug device of the present invention comprises a debugger and a target. The debugger comprises a break instruction setting part that writes a break instruction to a breakpoint when receiving a request for executing break instruction writing processing, and a program control part for starting up the target. The target comprises: a first storage device for storing a program as a debug target; a second storage device which is a loading destination of the program; and a loader which loads the program from the first storage device to the second storage device, and informs completion of loading to the debugger when the loading is completed so as to request break instruction writing processing.

Abstract: To lighten the load on a processor in DMA transfer, a DMA transfer apparatus 13 for executing DMA transfer between local memory 16 that each processor has and global memory 15 shared by the processors, wherein a DMA transfer termination notification is issued to the destination determined by referencing a table 14 for managing destinations to which a notification of DMA transfer termination is to be sent.

Abstract: The present invention discloses an image defocusing apparatus for defocusing an image formed on a screen by modeling an object in a boundary box by updating pixel values on the image to approximate a lens's focusing effects and a method thereof. The apparatus comprises a unit for computing data related to a circle of confusion for each point in the boundary box, the circle of confusion being a measure how defocused an out-of-focus point is on the screen, a unit for checking a reference pixel whose corresponding point's circle of confusion overlaps a pixel selected as a target pixel, and a unit for updating an original value of the target pixel by taking into account a value of the reference pixel and the data of the target pixel's circle of confusion.

Abstract: An ink-jet recording medium comprises a substrate and a pigment layer. The pigment layer comprises an upper layer and lower layer. The upper layer contains as a major pigment an aluminum oxide having a specific surface area ranging from 90 m.sup.2 /g to 170 m.sup.2 /g. The lower layer contains as a major pigment an aluminum oxide having a specific surface area smaller than the aluminum oxide in the upper layer, an inorganic pigment selected from a carbonate or silicate of calcium, a carbonate or silicate of magnesium, a silicate of aluminum and hydrotalcite having a specific surface are of not more than 150 m.sup.2 /g, or a basic magnesium carbonate having a specific surface area of not more than 150 m.sup.2 /g.
