The resolution of 5 (LCD) is main scanning direction: display width (96 mm), number of dots (320 d).
OT), 320 dots / (96 mm / 25.4 mm / inch)
≈84 dpi Sub-scanning direction: display width (72 mm), number of dots <240 d
Calculated from ot>, 240 dots / (72 mm / 25.4 mm / inch)
≈84 dpi, and the resolution is about 84 in both the main scanning direction and the sub scanning direction.
It is dpi. On the other hand, the resolution of the facsimile image is about 200 dpi (main scanning 8p
el, sub-scan is fine in 7.7 line / mm≈20
0 dpi), if one dot of the original image data is displayed as one display pixel as it is, the original image data is enlarged and displayed at about 240%. This is the maximum scale of the facsimile machine 100. In the facsimile apparatus 100, in order to reduce the processing by the CPU 101, the original image data is scaled by 1/2, 1/4, 1 /
The simple scaling process of 8 is performed to realize switching of the display scale in four steps, and the magnifications are about 240%, about 120%, about 60%, and about 30%, respectively.

[Flowchart of image processing] Next, RAM
The received image data stored in 103 is displayed on the liquid crystal display unit 11
A flow chart of the image processing for displaying the image on the display unit 5 will be described with reference to FIG.

First, the encoded received image data stored in the memory block of the RAM 103 is extracted in units of N lines and decoded (step S3).
01). Here, N is the optimum number of lines determined based on the image format of the original image data and the subsequent scaling processing. For example, in the facsimile apparatus 100, the original image data is MH.
If it is encoded image data, then 1/2, 1 /
In consideration of scaling to 4, 1/8, N is set to 4,
The original image data is extracted every four lines and decoded, and the binary data of the original image data is stored in the line buffer for four lines (step S302).

Next, the binary data stored in the line buffer is 8 bits (256 dots) per pixel (1 dot).
Sequential conversion to color data (step S30)
3).

Next, the image data of the same size and one page is not generated from the data obtained in step S303, but this data is reduced before the image data is generated.
That is, one page of RGB image uncompressed data (hereinafter referred to as raw data) that has been subjected to 1/2 scaling and 1/4 scaling from this data is generated (step S304), and is used as an intermediate buffer. The data is stored in the display buffer 1 and the display buffer 2, respectively (step S305). This reduced the size (1
The image data (2/2 scaled, 1/4 scaled) is stored in the intermediate buffer. The display buffer 1 and the display buffer 2 are, for example, the RAM 103 shown in FIG.
However, the present invention is not limited to this.
For example, it may be provided in a memory area in another memory.

As described above, the facsimile machine 100
Has a display scale of four stages in order to better display the image data according to the user's preference. This is because it is efficient to prepare and store two patterns of 8-bit raw image data suitable for resolution conversion processing in advance. The original image data stored in the display buffer 1 is ½ scaled display data (that is, H
alfDisplayData (hereinafter referred to as HDD), and the original image data stored in the display buffer 2 is ¼ scaled display data (that is, QuarterDisplayData, hereinafter referred to as QDD). Approximately 240% display by doubling the HDD, approximately 120% display by using the HDD as it is, Q
By using DD as it is, about 60% is displayed, QDD is 1
By displaying / 2, a display scale of 4 levels of about 30% is realized. The image processing for generating the two display data and the image processing for switching the display scale will be described later.

The above process is repeated for the received image data for one page, and when the CPU 101 determines that the process for one page is completed (step S306), H
A "window frame" (hereinafter, referred to as a virtual window) for cutting out image data matched with the display area for displaying on the liquid crystal display unit 115 on the DD or QDD is generated (step S307). In the facsimile apparatus 100, when a received document is first displayed on the liquid crystal display unit 115 so that the user can grasp what kind of received document it is when displaying the received document, for example, the received document is displayed. A display scale of about 30% may be used to display almost all of the.
The image data according to the display scale is subjected to the scaling processing of the image data from the memory area in which the QDD is stored, so that an initial virtual window is generated on the QDD. In this case, the facsimile apparatus 100 may have a function of automatically displaying the received image data on a display device such as the liquid crystal display unit 115 when the CPU 101 detects the end of the reception of the image data. .

The image data cut out by the virtual window is 1/2 with respect to the image data (1/4 image) having a display scale of 60% in order to obtain a predetermined display scale, for example, a display scale of about 30%. Is scaled and transferred to a built-in memory (not shown) of the liquid crystal display unit 115 (step S308).

Next, when the user selects a display scale and performs a switching operation while the received document is being displayed, a display scale switching process is performed (step S309). If the user has not performed a display scale switching operation, the image processing ends.

FIG. 4 is a flow chart showing details of the process of step S309 of FIG.

First, the CPU 101 determines whether or not the display scale has been selected by a user operation (step S4).
01). When the display scale is selected, the process branches into four based on the selected display scale. If the display scale is not selected, the process ends. When the selected display scale is 30%, a virtual window is generated on the QDD (step S402), the magnification is changed to 1/2 and the virtual window is transferred to an internal memory (not shown) of the liquid crystal display unit 115 (step S402).
403). If the selected display scale is 60%, QDD
A virtual window is generated above (step S404), and the image is transferred to the built-in memory (not shown) of the liquid crystal display unit 115 at the same size (step S405). The selected display scale is 120%
In this case, a virtual window is generated on the HDD (step S406), and the image is transferred to the built-in memory (not shown) of the liquid crystal display unit 115 at the same size (step S407). When the selected display scale is 240%, a virtual window is generated on the HDD (step S408), and the magnification is doubled and transferred to an internal memory (not shown) of the liquid crystal display unit 115 (step S4).
09).

The facsimile apparatus 100 generates 1/2 image and 1/4 image, stores them in the respective intermediate buffers, and performs the scaling process. However, in order to further reduce the memory size, the QDD is used. The 1/8 image is stored in the buffer that stores the data corresponding to
It is considered that the memory size can be further saved by scaling this image to 2 times when displayed at the display scale of. However, by naturally reducing the original image data to ⅛, a large amount of image data information is lost compared to the ¼ image. Since the deterioration of data is noticeable on the display screen, it may not be preferable for the user. Therefore, the intermediate buffer is configured by generating ¼ image instead of ⅛ image.

[Flowchart showing processing when generating display data] Conversion processing from raw data of monochrome binary when generating HDD and QDD to raw data of 256 colors / 8 bits will be described with reference to FIG. As mentioned above,
The image data of the HDD is the original image data scaled by 1/2, and the image data of the QDD is 1/4 of the original image data.
It has been scaled. Assuming that the memory capacity for one page of each image data can be stored up to B4 size, the main scanning of the original image data is 2048 bits in monochrome binary, and the memory size required to convert this into 256-color 8-bit data is 2048 bytes. Is. Assuming that the sub-scanning of the original image is 2784 lines, the following is performed.

HDD (2048/2) × (2784/2) = 1392 KBy
te (horizontal size 1024 Byte, vertical size 1392 Byte
e) ・ QDD (2048/4) × (2784/4) = 348 KByt
e (horizontal size 512 Bytes, vertical size 696 Bytes) The above two totals 1740 KBytes. This is 31.2 when compared with the capacity of 5568 KByte when the original image is directly converted to 256 color 8-bit data.
The capacity is about 5%, and the memory capacity can be greatly saved.

Next, the conversion algorithm for 8-bit data will be described.

The HDD and QDD are stored as color palette values. The color palette value that can be used is 0x00.
(Black), 0x49 (dark gray), 0x92 (light gray), and 0xff (white). That is, the generated display data has four gradations of monochrome, and also corresponds to a halftone image.

First, the encoded image data accumulated in the facsimile apparatus 100 is decoded by four lines per page, and the following processing is performed.

FIG. 5A shows the reduction processing in the sub-scanning direction.

(1) The sub-scanning direction is reduced by half by taking the logical sum of 8 pixels (1 Byte) for each of the first and second lines and the third and fourth lines, and the result is further reduced in the main scanning direction. A 1/2 image of 4 values (3 values) is created.

(2) The sub-scanning direction is reduced to 1/4 by taking the logical sum of 8 pixels for each of the first and third lines, and then the result is further reduced in the main scanning to obtain a 4-valued 1/4 image. create.

(3) The 1/2 and 1/4 images created in (1) and (2) are transferred to the HDD and QDD, respectively.
The value output to the buffer uses the color palette value.

FIG. 5B shows the reduction processing in the main scanning direction.

The table conversion shown in FIG. 5B is performed in units of 8 pixels. Table is 4 from 1 Byte (8 pixels) input
The pixel and the palette value for two pixels are output. The output palette value is determined by the number of black pixels in 2 pixels / 4 pixels before reduction.

When a 1/2 image is generated, the number of black pixels is counted every 2 bits, and 0, 1, and 2 black pixels are converted into palette values of 0xff, 0x92, and 0x00.

When a 1/4 image is generated, the number of black pixels is counted every 4 bits, and black pixels 0, 1, 2, 3,
0xff, 0x92, 0x49, 0x0 for 4
Convert to a palette value of 0, 0x00.

By these conversion processes, the monochrome binary data of the original image data is converted into 256-color 8-bit data, which is further reduced by 1/2 or 1/4 to generate the HDD and QDD.
Is stored in each memory area.

[Expansion from Virtual Window to Liquid Crystal Display RAM] In order to display image data on the liquid crystal display unit 115, the HDD and the QDD must be transferred to the liquid crystal display RAM. At this time, as described above, the HDD,
In order to cut out the image data to be actually displayed according to the display scale and the rotation angle selected on the QDD, the facsimile apparatus 100 generates a "window frame" which is a virtual window obtained by cutting out a part of the image data. .

FIG. 6 shows a conceptual diagram of the virtual window. As shown in FIG. 6A, the virtual window has a start point at the upper left corner of the window and is mainly composed of start point coordinates (Sx, S).
y), the horizontal length lx, the vertical length ly, and the center coordinates (Cx, Cy). Cx = (Sx + 1
x) / 2 and Cy = (Sy + ly) / 2.

For example, the entire area of the liquid crystal display unit 115 (32
0 dot x 240 dot) is used and the display scale is 240
%, If the start point coordinate is (20, 20), a virtual window is generated on the HDD, and the desired display image data can be obtained by doubling the HDD, so lx = 160
(= 320/2), ly = 120 (= 240/2), and Cx = 90 and Cy = 70.

FIG. 6B is a diagram showing a case where the virtual window shown in FIG. 6A is generated on the HDD. In the facsimile apparatus 100, the HDD stores 1 Byte (8 bits) of information per display pixel, and therefore, if the starting point coordinates are known, the address of the starting pixel can be easily derived. The start address of the HDD is 0xC0000
If it is 0, the address from the starting point coordinates to the starting point is H
Since the horizontal size of the DD is 1024 bytes (= 0x400), 20 + 1024 × 20 = 20500 (= 0x
5014), and 0xC00000 is added to 0x5014 to obtain 0xC05014. The start address of the second line in the virtual window is 0xC05414 by adding 1 line (0x400) to the start point address.
Becomes Further, as shown in the drawing, the scaling processing can be performed in units of bytes in the vertical and horizontal directions, and the built-in memory (not shown) of the liquid crystal display unit 115 can simply perform the scaling for each byte. The conversion process is also easy.

FIG. 7 is a diagram showing a transfer image to the liquid crystal display RAM at each display scale (magnification).

In FIG. 7A, the virtual window on the HDD is scaled by 2 and transferred at a display scale of 240%. In FIG. 7B, HD is displayed at a display scale of 120%.
The virtual window on D is transferred at the same size. Figure 7
In (c), the virtual window on the QDD is transferred at the same size at a display scale of 60%. In FIG. 7D, after the virtual window on the QDD is thinned out (for example, data processing when the QDD exceeds the virtual window) at a display scale of 30%, the virtual window is halved. Magnified and transferred.

(Second Embodiment) [Flowchart of Preview Operation] FIG. 8 shows an embodiment of performing a preview operation of facsimile received image data.
This will be described with reference to the flowchart of.

In the facsimile apparatus 100, the number of pages of the image data displayed by the preview is only one page, and, for example, the first page of the received image data (eg document data) is displayed. In this case, it is preferable that the page to be previewed is the first page even if the received image data extends over a plurality of pages.

First, the CPU 101 detects whether or not the reception of image data is completed (step S801), and the CPU
When 101 determines that the reception of the image data is completed, the first page of the corresponding received image data stored in the memory block of the RAM 103 is automatically read (step S802). In this case, as a method of detecting whether or not the reception of the image data is completed, for example, after the NCU 108 which is the communication line interface receives the image data from the communication line 900, all the pages of the received image data are stored in the RAM 103. It may be determined that the reception is completed when the data is stored.

Next, it operates according to the flow chart of the image processing shown in FIG. That is, the data of the first page of the received image data read in step S802 is N
Extraction is performed in units of lines, for example, in units of 4 lines and decoding is performed (step S803), and binary data of the original image data is stored in a line buffer for 4 lines (step S803).
804).

Next, the binary data stored in the line buffer is 8 bits (256 dots) per pixel (1 dot).
Sequential conversion to color data (step S80)
5).

Here, in the facsimile apparatus 100, for example, if the display scale of the preview image data is 30%, image data that has been magnified by 1/4 is generated (step S806), and the display buffer 2 as an intermediate buffer is generated. It is stored in (QDD) (step S807).

These processes are repeated for the received image data for one page, and when the CPU 101 determines that the process for one page is completed (step S808), Q
A virtual window is created on the DD (step S80).
9). The image data cut out by the virtual window is scaled by ½ and transferred to an internal memory (not shown) of the liquid crystal display unit 115 (step S810). By the above processing, the received image data is automatically displayed on the liquid crystal display unit 115 which is a display unit, so that the image data can be previewed immediately after the image data is received.

In the flowchart of FIG. 8, the preview operation is started at the same time as the reception of the received image data is finished. However, when the received image data for a plurality of pages is received, for example, the end of the reception of all pages is waited. Instead, the preview operation may be started immediately after accumulating the image data of the first page. FIG. 9 shows a flowchart of the preview operation of the first page in this case.

First, the CPU 101 determines whether or not the receiving operation of all pages of received image data (for example, image data including a received document) has been completed (step S901), 1
When the reception is completed with the received document of only the page (YES in step S902), the process branches to read the received image data corresponding to the first page from the memory block of the RAM 103 (step S903). If the received document of a plurality of pages is received, it is determined whether the reception of the first page is completed (step S902), and if the reception of the first page is completed (YE at step S902).
