摘要： An FFT analysis is performed on the decoded image data of one frame, and a cutoff frequency based on the assumption that the original signal has first-order attenuation characteristics is obtained in both the horizontal and vertical directions. A sampled-data H∞ filter (digital filter), previously designed to have different parameters corresponding to different cutoff frequencies is selected. By using this filter, a filtering process is performed on the image data decoded both in the horizontal and vertical directions. Since the variety of the analog frequency characteristics of the original image is taken into account for every frame of the image, the information that seems to be noise in the original image is less likely to be removed, and mosquito noise and block noise associated with a coding/decoding process can be efficiently removed.

摘要： A hearing aid tailored to a hard-of-hearing person is designed using sampled-data control theory. The method is for designing an audio signal processing system for a hearing aid, wherein the system comprises an AD converter for converting an analog audio input signal (yc) inputted to the hearing aid into a digital audio input signal, a hearing aid digital filter (K(z)) for performing a signal processing on the digital audio input signal outputted from the AD converter, and a DA converter for converting a digital signal outputted from the hearing aid digital filter into an analog audio output signal to be outputted to the hard-of-hearing person. The hearing aid digital filter (K(z)) is designed according to sampled-data control theory so as to reduce an error (ec) occurring between: a restored analog signal (zc) obtained from filtering the analog audio output signal outputted from the DA converter through an analog filter (P(s)) that has characteristics corresponding to auditory characteristics of the hard-of-hearing person; and the analog audio signal (yc) inputted to the hearing aid.

摘要： An FFT analysis is performed to the image data of one frame which has been decoded, and a cutoff frequency on the assumption that the original signal has first-order attenuation characteristics is obtained each in the horizontal direction and in the vertical direction. A sampled-data H∞ filter (digital filter) which has been previously designed in such a manner as to have different parameters corresponding to different cutoff frequencies is selected. By using this filter, a filtering process is performed to the image data which has been decoded both in the horizontal direction and in the vertical direction. Since the variety of the analog frequency characteristics of the original image is taken into account for every frame of image, the information that seems to be a noise yet actually exists in the original image is less likely to be removed, and a mosquito noise and block noise associated with a coding/decoding process can be efficiently removed.

摘要： A game apparatus causes a character object to perform a first hitting motion on the necessary condition that a to-be-hit object is present in a first area 104a which is set based on a position of the character object in a virtual game space, and causes the character object to perform a second hitting motion on the necessary condition that the to-be-hit object is present in a second area 104b, 104c, or 104d. Furthermore, the game apparatus adjusts a position of at least one of at least a part of the character object and the to-be-hit object, such that when the character object is caused to perform the second hitting motion, the character object and the to-be-hit object are in a predetermined positional relationship.
