5 is a flowchart showing the operation of the data display device according to the embodiment.

First, when an operator turns on a power switch (not shown), the MPU 8 executes a start-up program stored in the RAM 7 and initializes each control circuit connected to the MPU bus 5 (step S401).

Next, the MPU 8 reads the OS code from the external storage device 1 to the SCSI bus transfer control circuit 3 and instructs the transfer to the RAM 6 (step S402).

Next, the MPU 8 executes the OS code transferred to the RAM 6, and executes the keyboard control circuit 12 according to the OS code.
Is initialized (step S403), and the display control circuit 10 is instructed to display a prompt on the display device 11 (step S404).

Thereafter, the apparatus is in a state of waiting for input of a command for instructing sequential reading of image data or document data at predetermined time intervals (step S405).

In step S406, it is determined whether or not the operator has instructed the sequential reading of image data or document data stored in the external storage device 1 from the keyboard 13 at predetermined time intervals. If the sequential reading of the image data or document data has not been instructed at a fixed time interval, the process returns to step S405. If the sequential reading of the image data or document data has been instructed at a fixed time interval, the MPU 8 sets R
Execute the program of AM6 or ROM7, and execute the external storage device 1
The transfer of image data or character data stored in a file format to the buffer memory 4 is performed by the SCSI bus transfer control circuit 3.
(Step S407).

Next, the SCSI bus transfer control circuit 3 transfers the image data or character data of the external storage device 1 to the buffer memory 4 via the SCSI bus 2 (step S40).
8). Next, the title page detection unit 15
Is detected from the image data or character data stored in the page, and whether or not the page is a page including a title character is analyzed (step S40).
9). This analysis processing will be described later.

Next, the display time determination circuit 17 determines an appropriate display time based on the analysis result, and stores the display time in the display time register 16 (step S41).
0). A long display time is stored in the display time register 16 for a page determined to be a page including a title character. If the operator gives an instruction in advance, the display time can be unlimited, that is, the display time determination circuit 17 can be instructed to stop the display sequentially. At this time, the display time register 16 stores a value indicating that the display time is unlimited, for example, -1.

Subsequently, the MPU 8 temporarily stores the analyzed data in the display video RAM 9 through the display control circuit 10 in a state suitable for display, and displays the stored data on the display device 11 (step S411).

The MPU 8 monitors the timer 14 and decreases the value of the display time register 16 every time a predetermined time elapses (step S412), and proceeds to step S413.

In step S413, the operator monitors the display device 11 to determine whether desired image data or desired character data is being displayed. Step S4
If the desired image data or desired character data is not displayed in step 13, the process proceeds to step S414, and it is determined whether the value of the display time register 16 is 0 or -1.
If the value of the display time register 16 is not 0 or −1 in step S414, the process returns to step S412, and if the value of the display time register 16 is 0 or −1, step S41 is performed.
Go to 5.

In step S415, it is determined whether or not the value of the display time register 16 is 0. If the value of the display time register 16 is not 0, that is, if the value of the display time register 16 is -1, Then, the process waits for an instruction to sequentially read other image data or other document data at predetermined time intervals (step S416). When the instruction is input, the instruction is stored in the external storage device 1 in a file format. The processing from step S407 to step S417 to be described later is repeatedly performed with other image data or other character data.

At step S415, if the value of the display time register 16 is 0, the MPU 8 notifies the display control circuit 10 of the end of the display of the analyzed data, and the display control circuit 10 Is stopped (step S417), the process returns to step S407, and the processing from step S407 to step S417 is repeatedly performed on other image data or other character data stored in the external storage device 1.

In step S413, if desired image data or desired character data is displayed,
In accordance with the instruction to stop the sequential display input from the keyboard 13 by the operator, the keyboard control circuit 12 sends the instruction to stop the sequential display transferred from the keyboard 13 to the MPU.
8 and the MPU 8 stops displaying the image data or character data that has been sequentially executed (step S41).
8), the operation of the present device ends.

In this way, the operator peruses the desired image on the display device 11, prints it with a printout device (not shown), stores it in an external storage device, or performs transmission processing using a network device (not shown). be able to.

The character size measuring circuit 21 and the title discriminating circuit 23 are arranged in the RAM 6 or the ROM 7 and can be configured as program codes sequentially executed by the MPU 8.

Hereinafter, the analysis processing in step S409 in FIG. 5 will be described with reference to FIG. Here, FIG.
6 is a flowchart illustrating the analysis processing in step S409 in FIG.

First, the character size measuring circuit 21 examines the image data one pixel row at a time, and performs an OR operation on each pixel in each pixel row (step S501). At this time, it is assumed that 0 is stored in the white pixel and 1 is stored in the black pixel in the image data. If at least one black pixel exists in the adjusted pixel row, the result of the OR operation is 1, and the pixel is stored. If all the pixels in the row are white pixels, the value is 0. The calculation result is stored in the line buffer 22 corresponding to the image data (step S50).
2). The above processing is performed on all the pixel rows on the image data.

Next, the character size measuring circuit 21 checks the line buffer 22, and specifically checks how many consecutive pixel rows whose operation result is 1 appear (step S5).
03). The number of continuations of this calculation result corresponds to the vertical size of the character (FIG. 7). Here, FIG. 7 is an explanatory diagram in which the character size measuring circuit 21 measures the vertical size of a character.

If the vertical size continuously appearing in one piece of image data is h0, h1, h2,..., The maximum vertical character size in the image data is h-max = max (H0, h1, h2,...) (The largest one among h0, h1, h2,...) (Step S504).

The title discrimination circuit 23 compares this with a threshold value h-th set in advance (step S505). At this time, if h-max> h-th, it is determined that the page containing h-max is the page containing the title character (step S506).

At the same time, the result of analysis as to whether each page is a page including a title character is recorded in a title page database created in the external storage device 1.

Therefore, once the read operation of the image data or the character data is performed, a title page database is created in the external storage device 1, and whether or not each page is the title page is recorded in the title page database. In the second and subsequent reading operations, the reading operation can be performed at higher speed without analyzing whether the image data or the character data is the title page.

As described above, according to the first embodiment, the title page detecting section 15 detects a page including large-sized characters from the image data or the character data stored in the buffer memory 4, and detects the page. Is analyzed (step S409), based on the analysis result, the display time determination circuit 17 determines an appropriate display time, and stores the display time in the display time register 16. (Step S410) Since the display device 11 displays the image data or the character data, the display time of the page can be controlled and an efficient operation can be performed.

Is determined. The blank page detection unit 15 forms a page blank amount measuring unit and a page determining unit. The next page display time register 18 holds the display time of the next page of the data currently being displayed.
The functions of the other components of the display device are the same as those of the components of the page browsing device of FIG.

Hereinafter, referring to FIGS. 10 and 11,
The operation of the data display device according to the second embodiment of the present invention will be described. Here, FIGS. 10 and 11 are flowcharts showing the operation of the data display device according to the second embodiment of the present invention.

First, when an operator turns on a power switch (not shown), the MPU 8 executes a start-up program stored in the RAM 7 and initializes each control circuit connected to the MPU bus 5 (step S901).

Next, the MPU 8 reads the OS code from the external storage device 1 and instructs the SCSI bus transfer control circuit 3 to transfer the read OS code to the RAM 6 (step S902).

Next, the MPU 8 executes the OS code transferred to the RAM 6, and executes the keyboard control circuit 12 according to the OS code.
Is initialized (step S903), and the display control circuit 10 is instructed to display a prompt on the display device 11 (step S904).

Thereafter, the apparatus is in a state of waiting for input of a command for instructing sequential reading of image data or document data at predetermined time intervals (step S905).

In step S906, it is determined whether or not the operator has instructed the sequential reading of image data or document data stored in the external storage device 1 from the keyboard 13 at regular time intervals. If it is determined in step S906 that sequential reading of image data or document data has not been instructed at fixed time intervals, the process returns to step S905. If sequential reading of image data or document data has been instructed at certain time intervals, the MPU 8 stores the RAM 6 Alternatively, the program of the ROM 7 is executed to transfer the image data or character data stored in the external storage device 1 in the file format to the buffer memory 4 by SC.

9). This analysis processing will be described later.

Next, the display time determination circuit 17 determines an appropriate display time based on the analysis result, and stores the display time in the next page display time register 18 (step S).
910). A long display time is stored in the next page display time register 18 for a page determined to be a page including a title character.

Before the next page display time register 18 stores the display time, the MPU 8 copies the display time stored in the next page display time register 18 to the display time register 16 (step S911).

When the operator gives an instruction in advance, the display time can be unlimited, that is, the display time determination circuit 17 can be instructed to stop the display sequentially. At this time, the display time register 16 stores a value indicating that the display time is unlimited, for example, -1.

Subsequently, the MPU 8 temporarily stores the analyzed data in the display video RAM 9 through the display control circuit 10 in a state suitable for display, and displays the stored data on the display device 11 (step S912).

The MPU 8 monitors the timer 14 and reduces the value of the display time register 16 every time a predetermined time elapses (step S913), and proceeds to step S914.

In step S914, the operator monitors the display device 11 to determine whether desired image data or desired character data is being displayed. Step S9
If the desired image data or desired character data is not displayed at 14, the process advances to step S915 to determine whether the value of the display time register 16 is 0 or -1.
If the value of the display time register 16 is not 0 or −1 in step S915, the process returns to step S913. If the value of the display time register 16 is 0 or −1, step S91 is performed.
Proceed to 6.

In step S916, it is determined whether or not the value of the display time register 16 is 0. If the value of the display time register 16 is not 0, that is, if the value of the display time register 16 is -1, Then, the process waits for the input of an instruction for sequentially reading other image data or other document data at predetermined time intervals (step S917). When the instruction is input, the instruction is stored in the external storage device 1 in a file format. The processing from step S907 to step S418 described later is repeatedly performed with other image data or other character data.

In step S916, if the value of the display time register 16 is 0, the MPU 8 notifies the display control circuit 10 of the end of the display of the analyzed data, and the display control circuit 10 Is stopped (step S918). Returning to step S907, the processing from step S907 to step S918 is repeated with other image data or other character data stored in the external storage device 1.

If the desired image data or desired character data is displayed in step S914,
In accordance with the instruction to stop the sequential display input from the keyboard 13 by the operator, the keyboard control circuit 12 sends the instruction to stop the sequential display transferred from the keyboard 13 to the MPU.
8, and the MPU 8 stops displaying the image data or character data that has been sequentially executed (step S91).
9), the operation of this device ends.

In this way, the operator peruses the desired image on the display device 11, prints it with a printout device (not shown), stores it in an external storage device, or performs transmission processing using a network device (not shown). be able to.

Note that the compression circuit 21 and the comparison circuit 22
Alternatively, it can be configured as a program code arranged in the ROM 7 and sequentially executed by the MPU 8.

Hereinafter, the analysis processing of step S909 in FIG. 11 will be described with reference to FIG. here,
FIG. 12 is a flowchart illustrating the analysis processing in step S909 in FIG.

First, the blank page detector 15 determines whether each page of the image data or character data stored in the buffer memory 4 is compressed (step S10).
01). If it is determined in step S1001 that each page of image data or character data has been compressed, the process proceeds to step S1003, and the comparing unit 22 compares whether the data size of the compressed page is smaller than a preset value. . The result of this comparison is sent to the display time determination circuit 17.

In step S1001, if each page of the image data or character data is not compressed, each page of the image data or character data is compressed by the compression means 21 (step S1002), and step S100
Proceed to 3. At this time, the compression unit 21 compresses the image data using a known compression unit such as the MH, MR, MMR, or Lempel-Ziv method.

In step S1003, blank page detecting section 1
If the data size of the compressed page is smaller than a preset value, 5 is determined to be a page including many blanks, that is, the next page is determined to be a page including title characters, and the display time determination circuit 17 is determined. Causes the next page display time register 18 to store many display times (step S1).
004), this process ends.

In step S1003, blank page detecting section 1
If the data size of the compressed page is not smaller than a preset value, 5 is a page that does not include blanks, that is, it is determined that the next page is a page that does not include title characters, and the display time is determined. The circuit 17 stores a shorter display time in the next page display time register 18 (step S1005), and ends this processing.

Steps S1004 and S10
At the same time as the process of step 05, the result of whether or not each page is a page including a title character is recorded in the title page database created in the external storage device 1 according to the display time stored in the next page display time register 18. You.

Therefore, once the read operation of image data or character data is performed, a title page database is created in the external storage device 1, and whether or not each page is a title page is recorded in this. In the second and subsequent read operations, the read operation can be performed at a higher speed.
