[0013]
FIG. 2 is a flowchart showing an image processing operation in the network facsimile apparatus of this embodiment. In the figure, first, the facsimile received document file is opened (step S101). Then, the system control unit 107 in FIG. 1 determines whether the target image in the facsimile received document file is a normal character (200 × 100 dpi or 8 × 3.85 / mm) (step S102). If it is determined that the character is a normal character (step S102; YES), the double density processing unit 111-1 in FIG. 1 performs double density processing on the target image (step S103). On the other hand, if it is not a normal character (step S102; NO), the process proceeds to step S104 without performing the double density process. Here, the double density processing is processing for increasing the sub-scan line to 2 or 4 times and increasing the line to an arbitrary magnification. There are two types of methods, copy in software or hardware, in this case. It shall be simply doubled. In step S104, the data is transferred to the delivery destination. Finally, the facsimile received document file is closed (step S105). In this way, it is determined whether or not the resolution of the received facsimile image is equal to or lower than a predetermined resolution, for example, whether or not it is a normal character as described above. In this example, high-density processing is performed for normal characters, and double-density processing in the above example is performed, so that one line of the original image becomes two lines, so one line is thinned out at regular intervals during printing. Even so, the line never disappears.
[0014]
FIG. 3 is a flowchart showing another image processing operation in the network facsimile apparatus of this embodiment. In the figure, first, a facsimile received document file is opened (step S201). Then, the system control unit 107 in FIG. 1 determines whether the target image in the facsimile received document file is a normal character (step S202). If the result of the determination is a normal character (step S202; YES), double density processing is performed on the target image by the double density processing means 111-1 in FIG. 1 (step S203) and smoothing in FIG. Smoothing processing is performed by the processing means 111-2 (step S204). Here, in the binary smoothing process of a facsimile, a matrix of 5 × 5 or the like is usually extracted from image data, and data matching the black and white data pattern of the matrix is converted into smoothing data prepared in advance. Is. By performing such processing, the jaggedness of the image, particularly characters, is eliminated and the image becomes smooth. Although processing is possible with software, it usually takes place in hardware because of the processing time. On the other hand, if it is not a normal character (step S202; NO), the process proceeds to step S205 without performing the double density process or the smoothing process. In step S205, the data is transferred to the delivery destination. Finally, the facsimile reception document file is closed (step S206). In this way, the image received by facsimile is doubled in advance in the sub-scanning direction before being distributed to another server, and further smoothed to distribute the smoothed image. When printing with an arbitrary machine or printer, even if the printing machine does not have a smoothing function, it is possible to print with a smooth image.
[0015]
FIG. 4 is a flowchart showing another image processing operation in the network facsimile apparatus of this embodiment. In the figure, first, a facsimile received document file is opened (step S301). Then, the system control unit 107 in FIG. 1 determines whether the target image in the facsimile received document file is a normal character (step S302). If it is determined that the character is a normal character (step S302; YES), it is further determined whether or not the target image is larger than the standard size (step S303). If it is determined that the size is larger than the standard size (step S303; YES), the scaling factor is calculated from the number of lines of the document received by the scaling factor calculator 111-3 in FIG. 1 and the number of lines in the standard size. (Step S304). For example, since the received document is scaled to 1180 lines of A4 normal characters, 1169 lines of a standard size, corresponding to a small character, the magnification = 1169 × 2/1180 = 1.98 times. After calculating the scaling factor in this way (step S304), the double density processing by the double density processing means 111-1 in FIG. 1 and the smoothing processing by the smoothing processing means 111-2 in FIG. 1 are further performed (step S305, S306). In this case, the double density process is a process for increasing the sub-scan line to 2 or 4 times, and increasing the line to an arbitrary magnification. There are two types of methods: copying with software or hardware, but in this case If the received document has a standard size (step S304), the density is simply doubled, and if the received document is not a standard size, the double density process is performed at the magnification calculated in step S305. On the other hand, if it is not a normal character (step S302; NO), the process proceeds to step S307 without performing the double density process or the smoothing process. In step S307, the data is transferred to the distribution destination. Finally, the facsimile received document file is closed (step S308).
