Abstract:
An image conversion processing device converting non-interlaced image data comprising plural lines, which are stored in a storage unit and can be in any one of plural kinds of formats, to interlaced format image data, for a display device which conducts an interlace scan, said interlace scan displaying a plurality of fields, having a predetermined number of lines, comprising:an issue unit issuing a transmission instruction of the image data to the storage unit; and a converter converting the image data transmitted by said issued transmission instruction from the storage unit by one of a plurality of conversion methods, which is previously selected for the one of the plural kinds of formats, to generate the interlaced format image data and reduce a flicker between at least two of the fields, wherein said converter comprises: a linear interpolation unit conducting a linear interpolation on the image data of two adjacent image data lines of the non-interlaced image data to obtain a signal level of the line of interlaced format image data, and an averaging unit averaging signal levels of two signal levels of the lines of the interlaced format image data obtained in said linear interpolation unit.
