Abstract
This multi-primary-color display device (100) includes a multi-primary-color display panel (10) and a signal converter (20). The display device assigns a plurality of subpixels that form each pixel to a plurality of virtual pixels and is able to conduct a display operation using each of the plurality of virtual pixels as a minimum color display unit. The signal converter (20) includes: a low-frequency multi-primary-color signal generating section (21) which generates a low-frequency multi-primary-color signal; a high-frequency luminance signal generating section (22) which generates a high-frequency luminance signal; and a rendering processing section (23) which performs rendering processing on the plurality of virtual pixels based on the low-frequency multi-primary-color signal and the high-frequency luminance signal. The signal converter (20) further includes a magnitude of correction calculating section (24) which calculates, based on an input image signal, the magnitude of correction to be made on the high-frequency luminance signal during the rendering processing.
