Abstract

PURPOSE:To smoothly print a character by performing an interpolation processing to an enlarged dot pattern train which has been developed on a memory, based on information such as a leading address of the memory in which a dot pattern has been stored and a size, etc. CONSTITUTION:In facsimile equipment, in the case of enlarging a dot pattern of a character font, with respect to an enlarged dot pattern train which has been developed already on a memory, it is decided that an interpolation is necessary on a host control side. Subsequently, by performing the interpolation processing, based on information such as a leading number of the memory in which the dot pattern has been stored and a size of the dot pattern, etc., the interpolated dot pattern is developed on said memory. In such a way, a smooth character can be printed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine, and more particularly to a character interpolation method for a facsimile machine having means for enlarging and printing a dot pattern of a character font.

[Conventional technology]

Conventionally, this type of facsimile machine enlarges the dot pattern of a character font without performing interpolation.

[Problem to be solved by the invention]

The above-mentioned conventional facsimile machine does not perform interpolation when enlarging the dot pattern of a character font, so it has the disadvantage that the printed characters are rough.

[Means to solve the problem]

In the character interpolation method of the present invention, when enlarging the dot pattern of a character font in a facsimile machine, the upper control side interpolates the enlarged dot pattern string that has already been developed on the memo screen. is necessary, and performs interpolation processing based on information such as the starting address of the memory where the dot pattern is stored and the size of the dot pattern.
It has a character interpolation function that develops patterns.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a 16×16 dot pattern, and FIG. 2 is a pattern obtained by enlarging FIG. 1 to 32×32 dots without interpolation. Figure 3 is a 32x32 dot pattern obtained by interpolating Figure 2, and as shown in Figure 4(a), the reference point 1 is black, the lower right dot 4 is black, and the right dot is black. If the conditions that dot 2 is white and the lower dot 3 is white are satisfied, or as shown in FIG. 4(b),
Each dot 2 and tod 3 is converted to black only when the following conditions are met: reference point 1 is black, lower left dot 4 is black, left dot 2 is white, and lower dot 3 is white. This is the result of interpolation.

〔Effect of the invention〕

As explained above, the present invention can print smooth characters as shown in Figure 3 by performing simple interpolation on the enlarged dot pattern as shown in Figure 2, which was printed by conventional facsimile machines. It has the effect of printing.

[Brief explanation of the drawings] Figure 1 shows the 16x16 dot pattern of the character font, and Figure 2 shows the dot pattern of Figure 1 in 32x3.
FIG. 3 is a diagram showing a dot pattern enlarged to two dots; FIG. 3 is a diagram showing a dot pattern obtained by applying the interpolation method according to the present invention to the dot pattern in FIG. 2; FIG. 4(a);
(b) is a diagram for explaining the interpolation method according to the present invention. Agent Patent Attorney Shinho Uchihara 2 Kawa (d) Me 3 M So 4 Tou Cb)

Claims (1)

[Claims] In the character interpolation method of facsimile machines, when enlarging the pixel size of the dot pattern of a character font,
The upper control side determines that interpolation is necessary for the expanded dot pattern string that has already been developed in memory, and determines the starting address of the memory where the dot pattern is stored, the size of the dot pattern, etc. By performing interpolation processing based on the information, the interpolated dots and
Character interpolation method for facsimile machines that develops patterns.
