Abstract:
1. A subject determination apparatus comprising: an image obtaining unit that sequentially obtains frame images; a first obtaining unit that obtains, from a first region in a first frame image from among the obtained frame images, a first degree of similarity to a specific subject image; a first similarity degree determination unit that determines whether or not the first degree of similarity is equal to or more than a first threshold value; a first subject determination unit that determines that the first region is a region of the specific subject image, when the first similarity degree determination unit determines that the first degree of similarity is equal to or more than the first threshold value; a second obtaining unit that obtains, from a second region in a second frame image from among the obtained frame images, a second degree of similarity to the specific subject image, the second frame image being an image obtained before the first frame image by the image obtaining unit; a second similarity degree determination unit that determines whether or not the second degree of similarity is equal to or more than a second threshold value; and a second subject determination unit that determines that the first region is the region of the specific subject image, when (i) the first similarity degree determination unit determines that the first degree of similarity is not equal to or more than the first threshold value, and (ii) the second similarity degree determination unit determines that the second degree of similarity is equal to or more than the second threshold value.
