An image processing device for outputting four-color image data to a display section, the display section performing display using display pixels each composed of four sub-pixels, and having an arrangement of the display pixels in which a pixel arrangement in an even line of a scan lines and a pixel arrangement in an odd line of the scan lines are shifted a half pitch of the display pixels from each other, the image processing device comprising:
- a color conversion section that obtains the three-color image data and converts the three-color image data into a first four-color image data while maintaining the number of display pixels in the three-color image data;
- a conversion section that generates second four-color image data by performing an interpolation process on the first four-color image data based on a relationship between a position of a sub-pixel in the first four-color image data and a position of a sub-pixel in the display section;
- and
- an output section that outputs the second four-color image data to the display section.
