Image display apparatus and image display method

An image display apparatus that repeats displaying images for a left eye and for a right eye alternately that form a stereoscopic image, on a screen comprising a plurality of display lines, the image display apparatus comprising:

• a write-scanning section that sequentially writes display data of the images in the plurality of display lines;
• a light emitting section that allows the plurality of display lines to continue light emission, based on the written display data;
• a light emission timing controlling section that controls a timing to start continuous light emission from the plurality of display lines;
• and
• a shield timing controlling section that controls a timing to switch a shielding state of an eyewear which can shield views of the left and right eyes alternately, wherein:
• the write-scanning section writes the display data of the images in at least part of the plurality of display lines, in a period in which the shielding state of the eyewear is switched;
• the light emission timing controlling section controls the timing to start continuous light emission from the plurality of display lines without allowing the plurality of display lines to continue light emission in the period in which the shielding state of the eyewear is switched;
• and
• a time required for starting of continuous light emission from the plurality of display lines is shorter than a time required for write-scanning of the display data in the plurality of display lines.
