摘要： A method and an apparatus are provided which are capable of evaluating a state of a signal with a fewer number of samples compared with an error rate. A reproducing signal obtained from a magneto-optical disk is subjected to maximum-likelihood decode in a maximum-likelihood decoder, paths coupling with each other in the maximum-likelihood decode is detected by an evaluation index generation unit and, at the same time, a difference of likelihoods (path metrics) of those paths is obtained to adjust a parameter of a recording and reproducing signal or a control signal of an optical pickup based on the likelihood difference. The parameter is, for example, auto-tracking, a gain of an auto-focusing loop, or an offset value, or a gain value of a reproducing signal, a recording power, or a reproducing power intensity.

摘要： An apparatus is provided in which a parameter of Viterbi decoding is adjusted on the basis of a metric difference for evaluation of PRML signal quality to increase the error rate even when using a medium on which recording is performed under a large-distortion condition. When a reproduced signal is binarized by maximum likelihood decoding such that a state transition sequence most probable to be correct of m kinds of state transition sequences from a first state at time n−1 to a second state at time n is selected, a metric difference between the most probable state transition sequence and a second most probable state transition sequence at a predetermined time is computed, and a parameter (a reference amplitude value or a metric) of a maximum likelihood decoder is corrected on the basis of the metric difference to optimize maximum likelihood decoding operation.

摘要： An image combine apparatus for combining a plurality of images to generate a panoramic image. The image combine apparatus identifies an overlapping region of two inputted images and determines a boundary of the two images. The image combine apparatus then sets a tone correction area having a predetermined width such that the boundary of the two images is the center of the area, and performs tone correction within the area. The image combine apparatus performs linear tone correction in accordance with a distance between a pixel and the boundary. In the neighbor of the boundary of the two images within the tone correction area, density of the image gradually changes, thus a combined image whose boundary of the two images is inconspicuous is obtained.
