The image display apparatus according to an aspect of the present invention comprises: an image input device which inputs an image signal; a particular target detection device which detects a particular target included in the image signal based on a particular target evaluation value indicating the feature of the particular target; a frame display information generation device which generates frame display information indicating a frame surrounding the detected particular target and which causes the frame to change continuously or by stages according to the particular target evaluation value; and a display device which displays the frame based on the generated frame display information. That is, by causing the frame to change continuously or by stages according to the evaluation value of a particular target, it is possible to avoid sudden change in the frame display.
