Abstract:
A height detection apparatus successively changes the brightness of white light from a first level to a second level in accordance with a position of a Z stage and captures an image of interference light while moving a two-beam interference objective lens relative to a paste film in an optical axis direction, detects, as a focus position, a position of the Z stage where the intensity of interference light is highest in a period during which the brightness of white light is set to the first or second level, for each pixel of the captured image, and obtains the height of the paste film based on a detection result.

Claim (Index 5):
The height detection apparatus according to  claim 4 , wherein in the second step, a number of an image in which luminance of a pixel is highest in a period during which the brightness of the white light is set to the k-th level is obtained by obtaining a number of an image in which a difference between the luminance of a pixel in an image loaded this time and the luminance of a pixel in an image loaded previously is equal to or greater than a predetermined threshold and is largest in each constant cycle.
