These selected video signals are supplied to a video signal processing circuit (15) through an input terminal (14). In the video signal processing circuit (15), for example, a composite video signal supplied to the input terminal (14) is supplied. The video signal (15b) and the synchronizing signal (15a) are separated and the synchronizing signal (15a) is separated from the clock signal by the clock generation circuit (17).
Computer (hereinafter referred to as CPU ₁ ) (18).
Video signal (15b) separated by video signal processing circuit (15)
Is an analog-digital conversion circuit (hereinafter referred to as A / D) (1
6) is converted to a digital signal and supplied to the memory (2
2) is stored. The clock generation circuit (17) has a PLL configuration, and the first CPU ₁ (18) has a video signal processing circuit (15).
The number of scanning lines of the video input signal, the horizontal scanning frequency, etc. are measured based on the synchronization signal (15a) from the CPU, and based on the measurement result, the sampling frequency is set in the clock generation circuit (17), and the horizontal synchronization signal is set. A sampling clock synchronized with (H sync) is output from the clock generation circuit (17). A / D (1
6) performs sampling, and the video signal (15b) is written to the memory (22). The video input signal written in the memory (22) in this manner is transmitted to the first CP via the memory control circuit (23).
U ₁ (18) reads the data of the video signal (15b) in the memory (22) and supplies it to the print control circuit (19). The print control circuit (19) develops print data to be printed on the printing paper (21) by the thermal head (20), and
This print data is transferred to 0). A second computer (hereinafter referred to as CPU ₂ ) (24) is connected to the first CPU ₁ (18) by a data bus, and the second CPU ₂ (24) performs an operation like a host computer. That is, the second CPU ₂ (24) controls the memory control circuit (23), the print control circuit (19), the motor control circuit (25), etc., and displays various items on the above-mentioned LCD (5). A signal corresponding to various operations from the control panel (4) is generated. In particular, CPU ₂ (24) controls the photographic paper feed motor (2
It is made to control the speed of 6).

The operation of this example of the multi-scan video printer configured as described above will be described with reference to FIGS. In this example, for the number of scanning lines supplied to the input terminal (14) and video input signals with different horizontal scanning frequencies, the number of images to be taken into the memory (22) is calculated and displayed, and the optimum print is automatically performed. There is first in has been made in like performed, the power supply by pressing the the first step ST _1, as shown in the flowchart of FIG. 4 power button shown in FIG. 1 (6) is "on". The next second step ST ₂ in CPU ₂ (24)
Are initialized using the last set value as a set value. Determines whether no input or not in the third step ST _3. Display no input on as shown in the fourth step ST ₄ if no input LCD (5), the process proceeds to later. Video signal in the third step ST ₃ to select the aspect ratio manually fifth step ST ₅ if it is entered. This aspect ratio is displayed on the LCD (5) by pressing the picture mode button (9b), and the aspect ratio is 1: 1, 4: 3, 16:
Since 9 is displayed, the aspect ratio is selected by designating the aspect ratio to be selected from these aspect ratios using the cursor button (11). The second CPU ₂ (24) after such an aspect ratio selection is performed enters a sixth step ST ₆ of calculating the auto scan values. In the sixth step, the calculation of the auto scan value is performed based on the flowchart of FIG. That is, in the first step STP6-1 of FIG. 5, the horizontal scanning frequency (hereinafter referred to as fH) of the video input signal measured by the first CPU ₁ (18) is set to the second step STP6-1.
The CPU ₂ (24) receives and calculates a value obtained by multiplying this fH by, for example, a value of 1482 to calculate a sampling clock frequency fs. The value of 1482 is to be printed. For example, a thermal head (20) that determines a horizontal size (28) indicated by a portion c other than the portion b excluding at least the horizontal synchronization signal in the printing area (27) shown in FIG. ) Is obtained from the number of elements in the horizontal direction. The number of elements in the horizontal direction of a normal thermal head (20) is
It is about 1280 dots, but if the number of effective dots is 1216 dots and the horizontal effective ratio of this value is 0.82, it is 1216/1482 ≒
0.82, and the value of 1482 is obtained. When the sampling clock frequency fs is obtained in this manner, in the second step STP6-2 in FIG. 5, the second CPU ₂ (24) determines whether or not this sampling frequency fs is higher than 40 MHz.
The value of 40 MHz is determined by the limit value of the drive frequency of the A / D (16) and the memory (22) described in FIG. In this second step STP6-2, the sampling frequency fs is 40 MHz
If not larger, the horizontal size (28) is determined to be 1216 in STP6-4 of the next fourth step. Also, the second step STP6−
If the sampling frequency fs is greater than 40 MHz in
When the CPU ₂ (24) determines, the sampling frequency fs is set to 40 MHz in the third step STP6-3, and the horizontal size (28) is obtained in the next fifth step STP6-5 based on the sampling frequency fs. . In the fifth step STP6-5, the calculation of horizontal size = 40 MHz / fH × 0.82 is performed.
The value of 82% of the number of dots in one horizontal line is calculated. In this way, the horizontal size (28) is calculated corresponding to the video input signal. In the next sixth step STP6-6, the vertical size is calculated. The vertical size (29) in the vertical direction is, as shown in FIG. 6, at least the e-line as blanking out of the current number d of 1V scanning lines measured by the first CPU ₁ (18). Except for this, the vertical size is determined by multiplying the number of scanning lines by the number most appropriate for the vertical effective ratio, for example, 0.92, for printing in the f-line period.

When the calculation of the auto scan value of the sixth step ST ₆ shown in FIG. 4 in this manner ends, the second CPU ₂ (24) is the calculation of the memory number can capture the memory (22) as shown in FIG. 8 Make a comparison. The calculation of the auto scan value in the _sixth step ST6 shown in FIG. 4 is performed in the first step STEP6-1 in FIG.
As shown in (1), this operation is performed only when there is a change in the video input signal taken into the memory. 6th step ST in FIG.
₆ , that is, if the calculation of the vertical size has been completed in the sixth step STP6-6 in FIG. 5, the capacity of the memory (22) necessary for one image is calculated from the values of the horizontal size and the vertical size in the horizontal direction. X the number of dots in the vertical direction. That is, first volume of the horizontal size × vertical size in the second step STEP6-2 (hereinafter referred to as H _S × V _S) memory (22), i.e. than half the size (actually capacity of about approximately 2M is) It is determined whether it is small, and if “NO”, the third step STEP6-3
The memory number 1 indicating that the number of images that can be taken into the memory (22) is one is selected. 2nd step STEP
If 6-2 is "YES", proceed to the fourth step STEP6-4,
In the fourth step STEP6-4 H _S × V _S memory (22)
It is determined whether it is smaller than 1/4 of the size. If "NO", the process proceeds to the fifth step STEP6-5, and the memory number 2 indicating that the number of images that can be taken into the memory (22) is two is set. select. If the fourth step STEP6-4 is "YES" the flow proceeds to the sixth step STEP6-6, H _S × V _S is a memory 1/8
It is determined whether the number is smaller than "NO". If "NO", the process proceeds to the seventh step STEP6-7 to select memory numbers "3" and "4" indicating that the number of images that can be taken into the memory (22) is four. I do. If "YES" in the sixth step STEP6-6, the eighth step
Proceeding to step 6-8, a memory number indicating that the number of images that can be taken into the memory (22) is eight is selected.
The eighth step STEP6-8 corresponds to a case where one screen is divided into four equal parts in the multi-picture mode. The third step STEP6-3, the fifth step STEP6-5, the seventh step STEP6-7, and the number of images that can be stored in these memories by the ninth step STEP6-9 after the end of the eighth step STEP6-8. The number is displayed on the LCD (5), and after the display, the process returns to the first step STEP 6-1. The second CPU ₂ (24) determines the change state of the input signal. again to scan calculations ST ₆ is made so as to return to the first step STEP6-1 if "NO". After such a display flow is completed, the seventh step shown in FIG.
Proceed to ST ₇ .

FIG. 9 shows one method of displaying on the LCD (5) the number of video signals that can be captured in the memory shown in FIG. 8, and when the auto scan mode is established, an input to the multi-scan video printer is performed. Calculation automatically according to the video input signal to be performed according to the flowchart of FIG.
A comparison is made. For example, when the single picture mode is described for the sake of simplicity, when a high-definition video input signal having 1125 scanning lines is stored in the memory (22) as indicated by reference numeral (33). , Is displayed. This indicates that the number of images that can be stored in the memory is one and the number can be stored in the memory number 1 as shown in the right column of FIG. Also, when a video input signal or the like of NTSC having 525 scanning lines is stored in the memory (22), it is indicated by reference numeral (34). Is displayed. This display indicates that the number of images that can be stored in the memory (22) is two. Further, when a video input signal of a non-interlaced scanning system in the NTSC system is inputted, as shown by a sign (35), Is displayed as follows. This display indicates that the number of images that can be stored in the memory (22) hidden in the direction of the arrow is 3.4, that is, a total of four images. Pointer to memory numbers 1 and 2 (36)
Are printed when the print button (8a) is pressed and indicate the memory numbers to be printed out. When the skip button (8e) described in FIG. 3 is pressed, for example, FIG. In the LCD (5) display indicated by the sign (35), Appears, indicating that the data stored in the divided area indicated by the memory number 3 can be printed out. When the skip button (8e) is pressed further, the display on the LCD (5) This indicates that the storage data of the divided area indicated by the memory number 4 can be printed out. If the skip button (8e) is further pressed from such a display, the display can be changed to the display of the LCD (5) indicated by the reference numeral (34) in FIG. The display shown in the middle column (37) of FIG. 9 shows an example of a display method in the multi-picture mode.

Regarding the pointer (35), separate pointers may be provided for a memory from which a video input signal is to be captured and a memory from which a video input signal is to be printed.
As shown in the display (35) in the figure, when the four memories 1, 2, 3, and 4 are valid, four video input signals are fetched and changed to the video input signal having the next largest number of scanning lines. As a result, when only two images can be stored in the memory (22), the display of the number of images in the effective memory is performed for both the printing operation of four images and the operation of capturing the images in two memories. As shown, when the effective number of sheets for a new signal is different from that at the time of the last storage, it is easier to understand if each is displayed.

When the display operation shown in FIG. 8 is completed,
CPU ₂ (24) performs the automatic scanning mode determines whether the seventh step ST ₇ shown in Figure 4. Although if auto scan mode 8 proceeds to step ST ₈ the eighth step ST ₈ the auto scan button (12d) is made to "OFF" state, in this case, the sampling frequency and the like of the video input signal is very When it is high, the value may exceed the limit value of the drive frequency of the multi-scan video printer. When the number of lines is smaller than the set value, the auto scan button (12d) may be turned off. The image to be printed is indeterminate and has no meaning. Therefore, the eighth limit comparison of set values by the set value in step ST ₈ and the video input signal is made, "NG" state in the case when the ninth auto scan button in LCD (5) proceeds to step ST ₉ The user is instructed to press (12d). Ninth
In the case of the 8 OK state in step ST ₈ after the end parallel step ST9 of proceeds together. Further advances in the tenth step ST ₁₀ if the printer is made to auto-scan mode state in the seventh step ST _7. Changing the auto scan value calculated in the tenth step ST sixth step ST ₆ in _10. That is,
Rewriting is performed to the set value for taking into the memory (22). The tenth step ST ₁₀ after the end goes to. Proceeds to the eleventh step ST ₁₁ from are shown in the upper left of the flow chart of Figure 4. Video input signal in the 11 step ST ₁₁ it is determined whether the change. When the video input signal is changed back to the third step ST _3, it will be performed again calculates the auto scan values. If there is no change, whether twelfth step ST ₁₂ the print button (8a) is pressed a second CPU ₂ (24) determines. In this print operation, a print-in value memory-in and print operation are performed. If the print button (8a) is pressed, the operation will be described later. Print button copy proceeds (8a) is in the 13th step ST ₁₃ if it is not pressed button (8b)
Is determined by the second CPU ₂ (24) in the same manner. If "YES", the process will be described later. And the flow proceeds to the fourteenth step ST _14, if "NO" in the first 13 step ST _13.

Proceeds from the flowchart shown in upper right side of FIG. 1, if the print is determined whether performed at the 12th step ST ₁₂ "YES" to the 20 step ST _20, the second CPU ₂ (24) an error It is determined whether or not. When this error that there is the no-input is displayed on the LCD (5) as the fourth step ST _4, an instruction to press the auto scan button in LCD (5) as in the ninth step ST ₉ is in parallel If there is an error, go to step 21.If there is no error, go to step 21.
Change the printing settings in ST _21, the printing data capture to memory in the 22 step ST ₂₂ in the following, the calculation of the pitch is performed feeding in the next 23 step ST _23. This feed pitch is calculated as follows.

Thus the feed pitch is performed printing as shown in 24 step ST ₂₄ is required. Also, it is calculated pitch feed based on the image data before the copy button (8b) is stored in the printing setting value memory 23 step ST ₂₃ through if it is pressed, is printed.

Operation flowchart when the printing and presses the copy button (8a) and (8b) in the twelfth and thirteenth steps ST ₁₂ and ST ₁₃ in FIG. 4 is comprised as shown in Figure 10. When the first print button as in step STE ₁ (8a) is pressed in FIG. 10, the second CPU as shown in the second step STE _{2 2} (24) is a memory (22) to the video input signal Then, the image is divided into dividable sheets. Then performs writing of the video input signal in the memory of the divided areas selected in the third step STE ₃ skip button as shown in (8e), the divided areas selected in the skip button (8e) in the fourth step SET ₄ The memory is read and printing is performed. The fifth step in which the copy button (8b) is pressed
6th step in STE ₅ 2nd step as shown in STE ₆
STE ₂ and leave dividing the memory in the same manner cleavable number, are made as performs printing by reading the stored data written during print button (8a) presses the routine proceeds to a fourth step STE ₄ below.

Again, a fourteenth step ST ₁₄ shown on the left side of FIG.
Will be explained. In the fourteenth step, it is determined whether or not the auto scan mode has been turned from “off” to “on”. 10th step if “off” is changed to “on”
To change the setting ST ₁₀ in autoscan value, if "NO" in the first 15 step ST ₁₅ is auto scan mode "on"
Whether the determined, back to the eleventh step ST ₁₁ if "YES", if "NO", set proceed to the 16th step ST ₁₆ determines whether Edetto state. That is, in this case, the data value to be printed can be set by the manual operation. If "NO" in the first 16 step ST ₁₆ 11 step S
Although returned to T _11, "YES" change setting by the manual operation in the 17th step, if is performed. This state is the sixth
This will be described with reference to FIGS. Operation buttons for performing a manual operation in this setting edit include a format button (9c), a picture mode button (9b) and a scan Asiast button (9a). The format button (9c) determines post feed, page size, caption, baud rate, parity, etc. among the operation buttons, and the picture mode button (9b) controls contrast, brightness, the above-mentioned aspect ratio, , Medium, low filter,
Although the linearity and the like such as a negative state and a positive state are determined, since these are not directly related to the present example, detailed description is omitted.

When the scan asiast button (9a) is pressed, various items are displayed on the LCD (5) as shown in FIG. Display (5
a) The frame or field signal is input to the memory for printout by selecting whether the video input signal is a frame or a field with the cursor button (11). The display (5b) shows the horizontal shift amount in dot units. The horizontal shift amount (30) in FIG. 6 is adjusted, and 0 dot indicates a position that has not been shifted in the horizontal direction from the position set in the auto scan mode. That is, 0 dots are set based on the auto scan mode. For example, to shift 20 dots to the left, the cursor button (11) 6 until the display of "20 dots left" appears, the dashed line in FIG.
The dot will be shifted horizontally. The next display (5c) is used when manually setting the horizontal size (28) in units of dots, and the horizontal length, that is, the horizontal size, is C = 1216 dots as previously calculated. The total length in the horizontal direction is a (1H) = 1482 dots. The display (5d) adjusts the vertical shift amount (31) in line units.
The zero line indicates a position that has not been shifted in the vertical direction from the position set in the auto scan mode. That is, 0 lines are set based on the auto scan mode. For example, when it is desired to shift upward by 10 lines, the cursor button (11) is pressed. Is pressed until the display shows "10 lines below". In this case, the vertical shift (3
In the range indicated by 1), the image is vertically shifted downward by 10 lines with respect to the printing area (27). The display (5e) is used when the vertical size (29) in units of lines is manually set, and the measured number of lines in the vertical direction 2d = 2V is NT
In the SC system, the number is 525, but at least 2f = 478 excluding the blanking section 2e. The display (5f) is used to adjust the aspect. To change the aspect, use the cursor button (11). Pressing will enlarge the image horizontally. By pressing, the image in the horizontal direction is reduced. When the scan Asia strike by manual operation of such various items finish, the second CPU ₂ (24) proceeds to the eighteenth step ST _18, the limit comparison setting values with the current setting and the video input signal a 8 is performed as in step ST _8. This is because those through the ninth step ST ₉ to instruct to press the auto scan button (12c) passes through the first 11 steps ST ₁₁ ~ 17 step ST _17, the if the comparison output is "NG" 11 returns to step ST ₁₁ is, "OK" is long if the 19 step ST ₁₉
