摘要:
An image processing device includes: an analysis unit to analyze vector image data including line information and area color information; a detection unit to detect a boundary pixel through which an outline passes; a determination unit to determine whether the outline passes longitudinally through the boundary pixel; and a coloring unit to sequentially fill each pixel on a scan line. A color of a target pixel is calculated based on the area color information and the target pixel is filled with the calculated color when the target pixel is a boundary pixel. A reference filling color is changed from the first color to the second color defined for a target pixel when the target pixel is a boundary pixel through which an outline passes longitudinally. A target pixel is filled with the reference filling color when the target pixel is not a boundary pixel.

Having an outline font data readout unit read a correction subject pixel and surrounding pixels thereof, referring to the already stored pre-correction and post-correction brightness value pattern data that are related to the read correction subject pixel and surrounding pixels, deriving a post-correction brightness value pattern uniquely from among candidates for a post-correction brightness value pattern of an appropriate value as post-correction brightness value, determining the optimal post-correction brightness value from the uniquely derived post-correction brightness value pattern and outputting correction data based on the determined optimal post-correction brightness value, thereby changing a brightness value of a pixel within a character image giving a look of unnaturalness automatically to a brightness value not giving a look thereof.

A Bezier curve constituting outline font data represents a curve by four coordinate values of a start point, an end point, and two control points. The curve is represented by two coordinates of the start point and the end point in collinear approximation, and by three coordinates of the start point, an intersecting point of two lines, and the end point in bi-linear approximation. In curve pattern approximation, when 32 curve patterns are prepared, the curve is represented by 5-bit data of two coordinates of the start point and the end point, and a pattern number. By effectively employing these three kinds of processes, it is possible to represent a Bezier curve constituting the outline font data with a reduced data volume.

An information display method displays a plurality of display frames arranged in a table on a display screen. Each of the display frames enables display of a plurality of information pieces, and a selected display frame is enlargeable, while non-selected display frames are reduced according to an enlargement ratio of the enlarged display frame. Each of information candidates to be displayed in respective display frames includes an attribute of a display priority and an attribute of a display character size, and an information display operation is carried out, based on a size of each of the display frames, by deciding the display priority and the display character size of each of the information candidates to be displayed in the respective display frames. Consequently, a large amount of information can be displayed, and easy operation can be realized.

A display apparatus is designed to make a display corresponding to one pixel through the use of a plurality of rectangular display elements.The apparatus comprises a multi-gradation character generating unit for generating information on a multi-gradation character image obtained by gradating a character edge portion and an element display control unit for controlling a display state in a display unit on the basis of information on this multi-gradation character image so that the multi-gradation character image is displayed in a state where each of the rectangular display elements constituting the display unit is associated with one or more pixels, thus reducing the quantization error so that character display with high visibility is achievable in the case of display of highly fine characters.
