Claim One:
1. An optical image measuring apparatus comprising: an optical system including a scanner configured to change an irradiation position of signal light on an object and a focus position changer configured to change focus position of the signal light, and configured to detect interference light of returned light of the respective signal light from the object and reference light; and a processor configured to form a cross-sectional image based on detection results of a plurality of interference light corresponding to a plurality of irradiation positions of the signal light; control the optical system to irradiate the signal light onto the plurality of irradiation positions repeatedly while changing the focus position; form one composite cross-sectional image based on two or more cross-sectional images formed on the basis of results of repetitive irradiation of the signal light; and specify a partial image including an image region extending by predetermined distances in either direction along an optical-axis direction from a corresponding focus position for each of the two or more cross-sectional images, and compose specified two or more partial images to form the composite cross-sectional image, wherein a number of repetitions is determined based on a depth of focus and a frame height, and the composite cross-sectional image is formed based on the cross-sectional images corresponding to the determined number of repetitions, and wherein the partial image is specified to have a width obtained by dividing the frame height by the number of repetitions.
