Patent ID: 7102687

Claim:
An image conversion processing device, comprising: a receiver receiving non-interlaced image data, generated by a processor, the non-interlaced image data being in any one of a plurality of formats which have different numbers of lines of image data; a converter converting the received non-interlaced image data to interlaced format image data, having a plurality of interlaced fields to reduce a flicker of the interlaced format image data, wherein the converter changes the number of lines of the received non-interlaced image data when the received non-interlaced image data is in a predetermined format; a plurality of counters, each of the counters outputting different count values, respectively; a selecting unit selecting any output from the outputs of the plurality of counters, based on a mode data corresponding to the number of lines of the image data; and a table outputting a numerical value for selecting the image data outputted from a line storage unit and a coefficient for multiplication of the image data, based on an output selected by the selecting unit.
