Abstract: An imaging control device determining a group of parameters related to a shooting operation of a camera, comprising a communication circuit inputting imaging data generated by the camera and a control circuit selecting a group of parameters set in the camera from candidate groups of parameters based on the imaging data, wherein the control circuit acquires, via the communication circuit, each imaging data generated by the camera to which each candidate group of parameters is set, extracts a plurality of face images each including a human face, from the imaging data for each candidate group, calculates an evaluation value on image quality corresponding to a degree of match of automatic face recognition based on the plurality of face images for each candidate group, and selects any one group of parameters from the candidate group of parameters based on evaluation values on image quality.

Abstract: A still-image extracting method is disclosed. Frames of an object are extracted as still images from a moving image stream chronologically continuously captured by a camera. The camera moves relative to the object. First frames are extracted from the moving image stream. Image capture times of the extracted first frames are obtained. Image capture positions of the camera at the image capture times of the first frames are identified based on the first frames. Image capture times of the frames captured at image capture positions spaced at equal intervals are estimated based on both the image capture positions, identified by the first frames, of the camera and the obtained image capture times. Second frames at the estimated image capture times are extracted as frames captured and obtained at image capture positions spaced apart at equal intervals from the moving image stream.
