    摘要： An authentication processing apparatus for performing authentication based on a user's normal operation is provided. The authentication processing apparatus performs the authentication processing on the basis of operation information obtained from normally operating an information processing apparatus. Operation information obtained from operating an input unit by the user, such as a keyboard inputting mode, is obtained to serve as operation information, and the obtained operation information is checked against operation information registered in a database to perform authentication. Authentication is thus made possible without requiring the user to perform the special input processing for the authentication processing. Authentication is performed taking into consideration a plurality of pieces of operation information. With the checking processing in which less dispersed data is weighted, user authentication with high accuracy is made possible.

    摘要： For each pixel in an operation block, an effective pixel determining unit sets a predetermined pixel difference (threshold value) on a time-base pixel difference. When the time-base pixel difference is less than the set predetermined pixel difference, it is determined that the pixel contributes to (or are effective in) motion vector detection, and uses the pixel in the gradient method in the case of performing motion vector detection. When the time-base pixel difference is not less than the set predetermined pixel difference, it is determined that the pixel is regarded as having a possibility to generate irregularity in movement, and the pixel is excluded from the gradient operation in the case of performing motion vector detection. The present invention is applicable to a signal processing apparatus for performing frame frequency conversion from a 24 P signal to a 60 P signal.
