Patent ID: 7492481

Claim:
An image output device that creates dots on an output medium to complete a resulting output image, said image output device comprising: a dot data storage module that stores dot data representing a dot on-off state with regard to each of multiple pixels included in the image; multiple dot formation elements that are actuated to create dots simultaneously on multiple pixel arrays arranged at preset intervals; and a dot data supply module that reads dot data of the multiple pixel arrays, on which dots are to be created simultaneously by the multiple dot formation elements, out of said dot data storage module, converts the read-out dot data into high-resolution dot data, and supplies the high-resolution dot data in an order of actual dot formation to the multiple dot formation elements, wherein each of the multiple dot formation elements is capable of creating different types of dots having variable sizes, said dot data storage module stores a selected type of dot to be created in each pixel as the dot data, and said dot data supply module converts dot data of each pixel into data of plural divisional pixels where the selected type of dot is to be created in a preset distribution, and supplies the data of the plural divisional pixels to the multiple dot formation elements.
