1. An image generation device that generates a display image to be viewed through an eyepiece disposed in front of a display panel, the image generation device comprising:
a source image reception control section that receives a source image from a content processing device;
a distorted image generation section that generates data on pixels in a display image obtained by giving the source image a distortion corresponding to the eyepiece;
a partially distorted image storage section that stores the data on the pixels in an order of data generation; and
an image display control section that, whenever data on a predetermined number of pixels smaller than a total number of pixels in the display image is stored in the partially distorted image storage section, outputs the stored data to the display panel,
wherein, the source image reception control section constantly monitors reception of each row of pixels of the display image and instructs the distorted image generation section to start a process of generating data for each row of pixels after it is determined that each row of pixels is received by the source image reception control section.
