Claim One:
1. An object detection apparatus for detecting an object to be detected from a frame image, comprising: circuitry configured to: set a window to be used for detection of the object to be detected in the frame image and acquire a first window image having an image of the window; generate second window image by acquiring a value smaller than a pixel value of a pixel inside the first window image acquired by the circuitry when the pixel value is smaller than a correction reference value; calculate a feature amount of the second window image generated by the circuitry; determine whether or not to use the second window image for calculation of an identification value indicating whether or not the object to be detected is present in the window based on the feature amount calculated by the circuitry; and calculate the identification value indicating a degree of presence of the object to be detected inside the second window image by using feature data of the object be detected when the circuitry determines to use the second window image.
