Abstract
An image processor produces a cross-faded image from first and second image data and first and second control data. The cross-faded image corresponds to a product of the first image data and the first control data and a product of the second image data and the second control data. The image processor includes a first address generator which generates a first l-bit address signal made up of the upper (n-k.sub.1) bits of the first n-bit image data and the upper (m-k.sub.2) bits of the first m-bit control data. Similarly, a second address generator is provided which generates a second l-bit address signal made up of the upper (n-k.sub.1) bits of the second n-bit image data and the upper (m-k.sub.2) bits of the second m-bit control data. The number of bits l of each address signal is less than a sum of the bits n and m of each of the image data and control data. The first and second address signals are used to access a ROM which is used to generate corresponding first and second product data. The product data is summed to generate cross-faded image data.
