Abstract
An image conversion device is provided with a first buffer area for storing either one of even field and odd field of inputted dot sequential data and a second buffer area for storing the other thereof. A data transfer control circuit controls in such a manner that, during a period in which one of the two fields is written in the first buffer area, the other field, stored in the second buffer area, is read out in a color field sequential format, and during a period in which the other field is written in the second buffer area, the other field, stored in the first buffer area, is read out in a color field sequential format. A pixel interpolating circuit carries out an insertion-interpolating process on the field read out from the image storing unit, and outputs the resulting data. Thus, it becomes possible to prevent color breaking at the time of displaying motion images on a color field sequential type display by using a buffer area having a capacity of one frame.
