摘要： In a main area of a display device, buttons and a map display area where a map is scrolled are provided. A cursor can be moved to an arbitrary position of the main area according to directional input received from an input device. When a decision input is performed with the input device when the cursor points to each button, processing assigned to the button to which the cursor points is performed. When a user inputs a direction and a special input button is not selected, the cursor is moved throughout the main area. When the user inputs a direction while the special input button is selected, the cursor is moved only within the map display area and the map is scrolled as required.

摘要： A setting information database associates setting information used to output a video signal or an audio signal with a corresponding viewing condition. A setting information registration unit registers setting information and a corresponding viewing condition which have been received by a setting information reception unit so as to store them in the setting information database. An adequacy determination unit determines the adequacy of recommended setting information to be stored in the setting information database. A condition extraction unit extracts pieces of setting information stored in the setting information database on the basis of a viewing condition supplied from an extraction condition reception unit. A recommendable setting derivation unit derives recommendable setting information from the extracted pieces of setting information.

摘要： A lattice dividing unit determines lattice lines to divide parameters of all points of a picture at every division and supplies distortion correction parameters (distortion correction coordinates) on the lattice points to a distortion correction memory (not shown). A polynomial of degree n coefficient deriving unit expresses all distortion correction coordinates on each lattice line in the form of a function relative to positions on lattice lines and approximates the distortion correction coordinates by desired division polynomial of degree n. Further, a sample point deriving unit compresses distortion correction parameters based upon the division polynomial of degree n obtained from the polynomial of degree n coefficient deriving unit. In the derived division polynomial of degree n, internal points which result from dividing both ends of the division polynomial of degree n by n is supplied to the distortion correction memory as new distortion correction parameters (approximated distortion correction coordinates). Thus, a memory capacity of a required memory can be reduced in the image processing for correcting distortion of an image.

摘要： Inter-field-interpolation spatial transition is calculated based on the sum of absolute values of differences between pixel values of an inter-field-interpolated pixel and adjacent pixels on the same field. Inter-field-interpolation temporal transition is calculated based on the sum of absolute values of differences between pixel values of the inter-field-interpolated pixel and pixels at corresponding positions on previous delayed field and present field. Intra-field-interpolation temporal transition is calculated based on the sum of absolute values of differences between pixel values of an intra-field-interpolated pixel and the pixels at the corresponding positions on the previous delayed field and the present field. The amounts of error in the interpolated pixels are calculated based on information of the inter-field-interpolation spatial transition, inter-field-interpolation temporal transition, and intra-field-interpolation temporal transition, and a pixel is generated by switching between inter-field interpolation and intra-field interpolation accordingly.
