A control unit calculates the expected number of access operations to each recorded data set, and selects one or more recorded data sets as recorded data sets to be relocated, based on the expected number of access operations. The control unit calculates the expected number of access operations to each recorded data set, based on a calculation period and the number of access operations per unit time. The calculation period differs from one recorded data set to another, depending on the next update timing. If the next update timing is earlier than the next relocation timing, the calculation period is a period from the current relocation timing to the next update timing. On the other hand, if the next update timing is later than the next relocation timing, the calculation period is a period from the current relocation timing to the next relocation timing.

From unit storage areas each having a certain size in a first storage device, an extraction unit extracts, at certain time intervals, a monitored area formed by consecutive unit storage areas having been accessed at least a predetermined number of times that is greater than zero and being similar to each other in the number of times of access. When detecting movement between the positions of same-sized monitored areas among the extracted monitored areas over time, a prediction unit determines a predicted storage area predicted to be accessed in the storage area of the first storage device on the basis of the direction of the movement between the positions of the same-sized monitored areas, and performs a control operation so that the content of the predicted storage area is copied to a second storage device that provides faster access than the first storage device.

Outline font brightness value correction system, method and program

A Bezier curve constituting outline font data represents a curve by four coordinate values of a start point, an end point, and two control points. The curve is represented by two coordinates of the start point and the end point in collinear approximation, and by three coordinates of the start point, an intersecting point of two lines, and the end point in bi-linear approximation. In curve pattern approximation, when 32 curve patterns are prepared, the curve is represented by 5-bit data of two coordinates of the start point and the end point, and a pattern number. By effectively employing these three kinds of processes, it is possible to represent a Bezier curve constituting the outline font data with a reduced data volume.
