Abstract
Abstract Image signals corresponding to a first row of the image are horizontally scaled and stored in an external memory device. A first portion of the horizontally scaled first-row image signals are retrieved from the external memory device and stored in an internal memory device. Image signals corresponding to a first portion of a second row of the image are horizontally scaled and partially vertically scaled first-portion image signals are generated from the first portion of the horizontally scaled first-row image signals and the first portion of the horizontally scaled second-row image signals. The partially vertically scaled first-portion image signals are stored in the external memory device. A second portion of the horizontally scaled first-row image signals are retrieved from the external memory device and stored in the internal memory device. Image signals corresponding to a second portion of the second row of the image are horizontally scaled and partially vertically scaled second-portion image signals are generated from the second portion of the horizontally scaled first-row image signals and the second portion of the horizontally scaled second-row image signals. The partially vertically scaled second-portion image signals are stored in the external memory device.
