Abstract: PROBLEM TO BE SOLVED: To obtain a clear enlarged image by reducing a step-shaped or chain- shaped oblique line, and reducing deformation or disappearance of a formation line of font or a graphic. SOLUTION: In this image conversion method, inputted original image data are converted into rational number magnification or integral number magnification image data. The method includes a vertical/horizontal direction interpolation part 12 for weakening correlation in the vertical and horizontal directions of an image, and generating first enlarged image data, relative to the image obtained by linearly enlarging in the vertical and horizontal directions the original image data inputted from an original image data input part 11; an oblique direction interpolation part 15 for generating second enlarged image data by linear interpolation, using near pixels based on correlation with the near pixels in the oblique direction, relative to processing object pixels forming the original image data inputted from the original image data input part 11; and a final result generation part 18 for generating a result image from the generated first enlarged image data and the second enlarged image.

Abstract: PROBLEM TO BE SOLVED: To express a font and fine line in clear colors with respect to a graphics picture which is handled in an information display of an LCD panel, a projector, etc., and includes many step edges such as fine lines. SOLUTION: This picture processor is provided with an original picture data input part 11 for inputting original picture data having low resolution, a connection detector 13 for recognizing a connecting relation between a picture element in consideration and an adjacent picture element in the original data, a rule applying device 17 which defines plural types obtained by sorting a relation between the coordinate position of a picture element and the coordinate position of result pixel in magnified picture data and applies a rule, and a result outputting part 19 for deciding the value of the result picture element to output the magnified picture data. When the picture element under consideration is judged to be a picture element constituting a line of one picture element width by the recognition by the detector 13, this device 17 applies such a rule as maintains one picture element width even in the magnified picture data.

Abstract: PROBLEM TO BE SOLVED: To reduce power consumption of a video controller with a simple constitution by lowering the operating frequency of the video controller in response to the notification from an OS showing an idle state of a computer in a state where the computer is not set in a power saving mode when viewed from a user.
SOLUTION: If no job is processed by a CPU, the idle state is decided by a power management driver 17. Thus, a CPU
- Idle 31 is notified to a power management BIOS 19. The BIOS 19 checks a status register 7a of a video controller 7. If it's confirmed that the controller 7 is executing no operation other than a display job, the BIOS 19 sets the deceleration of an MCLK via the controller 7. Then the MCKL is lowered down to the lowest necessary frequency that is decided by the VLCK which is used for outputting the data to a display device 9.

Abstract: PROBLEM TO BE SOLVED: To attain power management with excellent balance between usability and power saving by increasing the operation frequency of CPU when the prescribed action of a device in a computer system, which occurs without an interval being more than the first prescribed time, is continued for more than the second prescribed time. SOLUTION: CPU 1 is provided with few data to be processed in a normal state so that a proportion for asserting an STPCLK# signal 31 is increased in a support circuit 2(7) in order to save power. The STPCLK# signal 31 is inputted to a control circuit 13. The control circuit 13 monitors the bus cycle of a PCI bus 5 and a DASP# signal 35 which is outputted by an HDD controller 15. When it becomes clear that an event to be executed correspondence occurs by the result of the monitoring, an STPCLK2# signal 33 obtained by correcting the STPCLK# signal 31 from the support circuit 2(7) is inputted to CPU 1.
