1. An image processing device comprising:

  • a brightness information calculation portion operable to calculate brightness information of an image signal that can form an image made up of pixels, the calculation being performed per pixel or per pixel region made up of a plurality of pixels;

    an interest level estimation portion operable to estimate an interest level indicating the degree to which the pixel or the pixel region is visually focused on in the image, based on the brightness information;

    a vanishing point estimation portion operable to estimate vanishing point information of the image, based on the brightness information;

    a depth estimation portion operable to estimate a degree of depth based on the interest level and the vanishing point information and calculate a correction gain for performing a depth correction process on the image signal based on the degree of depth; and

    a depth correction portion operable to perform the depth correction process on the image signal based on the correction gain.
