    摘要: A device generates coefficient data of an estimating equation for converting a first information signal to a second information signal. The device performs decimation on a teacher signal to generate a student signal and acquires plural training data items from the teacher signal corresponding to the second information signal and the student signal corresponding to the first information signal. For each training data item, a similarity determination unit acquires the similarity of the student signal with respect to the first information signal corresponding to a second information signal at a position of interest. Coefficient seed data, which are coefficient data of a generation equation including the similarity as a parameter, are determined using the training data items and the similarity. A coefficient data computing unit determines, based on the generation equation, coefficient data of the estimating equation using the coefficient seed data and a similarity value indicating the highest similarity.

    摘要: A receiver measures strength of magnetic field generated by a transmitter and supplies it to a computer. The computer detects a viewpoint of a viewer based on the strength. The computer sets each pixel-displaying element arranged on the display portion of image display as a subject pixel-displaying element in turn. The computer obtains set pixel data from multiple items of pixel data constituting image data of one screen as pixel data corresponding to the subject pixel-displaying element. The image data has been obtained by a camera arranged for a position on an imaged plane corresponding to the split area in the display portion including the subject pixel-displaying element and stored in data storage. The set pixel data corresponds to a beam of light irradiated from the object along a straight line connecting the viewpoint and the subject pixel-displaying element. The computer supplies the set pixel data to a display.
