Abstract: In the image processing apparatus, an image data control unit is connected to at least one of an image reading unit, an image memory control unit, an image processing unit, and an image writing unit. The image data control unit receives any one of an image data read by the image reading unit, image data read by the image memory control unit, and image data processed by the image processing unit. The image data control unit transmits the received image data to any of the image memory control unit, the image processing unit, and the image writing unit.

Abstract: In the image processing apparatus a matrix selector selects a position matrix for determining the gradation direction. The gradation direction is the direction of a contrast of a gradation at a position of a target pixel and a dispersion matrix for determining a spatial frequency at the position of the target pixel. Further, a pixel interpolator divides the target pixel into still smaller pixels. A table selector selects a conversion table for determining a gradation level of the smaller pixels based on the gradation level of the target pixel, the position matrix and the dispersion matrix.

Abstract: The image processing device comprises a first function block section formed of functional blocks which require a supply of power so as to maintain the image processing device in an operating state when the power supply is on, and a second function block section formed of functional blocks which need not be supplied with the power so as to maintain the image processing device in an operating state even when the power supply is on. The supply of power to the second function block section can be stopped when desired, while continuing the supply of power to the first function block section, thereby saving the power.
