    摘要： A signal processing device that learns the operation of a user while the user is being unconscious of it and allows the user to carry out an operation the most suitable for the user. A learning unit (22) monitors an operation signal fed in response to the operation of the user and judges whether or not it can be used for the learning. If the operation signal is a learning one which can be used for the learning, the learning unit (22), referring to the learning operation signal, learns a correction criterion which is a criterion for correcting an input signal. A correction unit (21) corrects the input signal on the basis of the correction criterion obtained by the learning, and the corrected signal is outputted as an output signal. The signal processing device can be applied to an NR (Noise Reduction) circuit for reducing noise.

    摘要： An image processor and an image processing method that can perform matching processing only with a low degree of computational complexity and accurately detect a motion vector. The image processor comprises a first feature amount extraction unit (13) that extracts a feature and the space coordinates of a pixel of interest from information on the current frame; a second feature amount extraction unit (14) that extracts from information on a reference frame a feature, a pixel of interest, the space coordinates of the pixel, the space coordinates of the neighboring area of the pixel, and distance information on the space coordinates of the pixel; a database creation unit (15) that creates a database containing the correspondence relationship among the feature, the pixel, the space coordinates of the neighboring area of the pixel, the space coordinates of the pixel, and the distance information on the space coordinates of the pixel extracted by the second feature extraction unit (14); and a motion vector detection unit (16) that obtains from the database the space coordinates of the movement destination by calculating, through a search, the distance information linked to the feature according to the feature extracted by the first feature extraction unit (15).

    摘要： A storage device, a signal processor, an image signal processor, and a signal processing method that can perform matching processing only with a low degree of computational complexity and accurately detect a motion vector. The device comprises an ME memory (13) in which stored is information including position information generated by converting features which include the pixel values in a block range the center of which is a pixel of interest into addresses according to information on a reference frame Fr stored in a second frame memory (12); and a matching unit (14) that reads information stored in the ME memory (13), using the feature of the pixel of interest included in information on the current frame Fc supplied from a first frame memory (11), as the feature address, calculates the distance between the pixel of interest within the current frame and the feature address (position coordinates) read from the ME memory (13), and determines differential coordinates which are based on the position information on the position whose distance is the minimum among a plurality of candidates, as the motion vector (Vx, Vy) of the pixel of interest.
