Abstract:
1. An image processing controller which converts pre-conversion image data with each pixel being represented in multi-gradation into post-conversion image data with each pixel being represented by binary to indicate a print pixel or a non-print pixel, the post-conversion image data being higher resolution than the pre-conversion image data in a row direction and a column direction, a pixel block consisting of pixels arranged in an array of two rows and two columns or more in the post-conversion image data is corresponding to one pixel in the pre-conversion image data, the image processing controller comprising: a pixel number determining unit that determines the number of print pixels included in the pixel block based on a gradation of a pixel of the pre-conversion image data; a print pixel location unit that a switching unit that switches between the first and second location modes to be executed by the print pixel location unit based on predetermined information possessed by the pre-conversion image data.
