Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data imprinting device mounted on an optical device such as a camera.

[0002]

2. Description of the Related Art Conventionally, a data imprinting device for a camera is
It is configured to turn on the light emitting elements arranged corresponding to the characters and symbols to be imprinted.

[0003]

However, the conventional data imprinting device has the following problems. In the imprinting on film, if the background of the imprinted part is bright and white or there is a pattern when the characters and pictures are lit, the imprint in the photo becomes unclear. I will end up.

Depending on the content of the imprint, it may or may not be desired to make the imprint stand out in the photographic print, and it is not preferable in use to always make the imprint stand out.

An object of the present invention is to solve the above-mentioned problems and to provide an improved data imprinting apparatus capable of changing the imprinting expression more freely than the conventional apparatus.

[0006]

An improved data imprinting device according to the present invention is characterized by having the following configurations and functions. In order to make the imprint stand out in the photograph, a second imprint mode is provided in which the characters and pictures to be imprinted are turned off and the other imprinted parts are illuminated. When the imprinting is not desired to be conspicuous, a switching means is provided for switching to the first mode in which a normal character or picture portion is illuminated.

[0007]

When the content of the data imprinting is desired to be conspicuous on the photographic print, the imprinting can be reversed to make it conspicuous as necessary. In the case of a photograph that is not desired to stand out, ordinary imprinting is also possible and the two requirements can be satisfied. When the second mode is selected, since at least one dot indicating the imprint end is added to both ends of the imprinted character, the ringing of characters in the second mode becomes clear.

[Table 4]

In the above structure, when the camera is powered on, the voltage detection circuit 8 outputs a reset pulse.
When this reset pulse is input to the microcomputer 1, the sequence starts from START in FIG. The reset pulse is also simultaneously input to the frequency dividing circuit 10, the year, month, and day counters, and the 11 to 13 message counters 20 so that they are also reset.

First, in step # 001, the memory in the RAM area is cleared, and in step # 002-4, the dot LED lighting control ports (OPLED1 to HLED).
0 is output, and the DF / F of the imprinting pulse detector is reset in step # 005.

Next, in step # 007, a state is waited for the data imprinting to be enabled. Now, when the release switch (not shown) is pressed and the photographing is finished with the film loaded in the camera, in FIG.
The camera control circuit 16 outputs a signal for driving the wind motor to wind the film, and the film is wound, but the motor drive signal is input from the iPDEN port in the microcomputer 1 and iPDEN = 1, and the sequence is stepped. Go to # 008. In step # 008, the imprinting mode is determined. If the date / calendar mode is determined (iPCAL = 1), the font address for imprinting only the calendar data is set in step # 011.

Next, in # 011, the imprinting position offset in the date calendar mode is read (4 in this case), and in # 012, the four least significant digits (PD0 to PD0) are read.
ROM by loading the font address of the space to PD3) and copying the lower digit (rightmost digit on the print) PD4M to the first digit (DAYL) of the calendar date digit and loading 7 to the upper address. Referring to the font table (Table 4), if the upper address is 7, the same font as the value of the middle address is stored. In this case, the font designation of the lowest digit of the imprinting is the first digit (DAYL) of the calendar date digit. ) Value. Similarly, the next digit of the imprint is the value of the tenth digit (DAYH) of the calendar month digit. Next 7th from the lowest digit of imprinting (DiGiT6)
The font designated as is a blank font because the middle address (PD6M) is 5 and the upper address (PD6H) is 9, (see Table 3). Similarly, DiGiT
7 is the 1st digit of the month digit, DiGiT 8 is the 10th digit of the month digit, DiGiT 10th digit of the 1st digit, DiGiT 11th digit of the 10th digit, DiGiT 12 is “,” (single quotation), DiGiT 9 and DiGiT0 to Di
For GiT3 and DiGiT13 to DiGiT17, the addresses of the blank fonts are loaded, respectively, so that the date data is offset by 4 digits for the entire imprint and is imprinted substantially at the center.

On the other hand, if the message mode is determined in step # 008 (iPCAL = 0), step # 009.
Or, in step # 010, the value of the message counter 20 is determined to determine the type of the imprinting message, and the address for designating the font is set. The font address to be set in each imprint message and each imprint digit is shown.

The offset data of the imprinting position for each message is stored in the contents of the data memory in Table 2 RAM.

In this example, assuming that the content of the message counter is 0, for example, "HAPPY BIR
The message of "THDAY" and the data of "year" are imprinted.

"HAPPYΔBIRTHDAY '□□"
In the case of (□□ represents year and Δ represents blank), the offset value is 0 because all digits of the imprint are used.

That is, DiGiT0 and DiGiT1 are set with fonts (yL and yH) of the first digit and the tenth digit of the year at that time, and DiGiT2 "," (single quotation), DiGiT3 to DiGiT.
The address of the font is loaded as “YADHTRIBΔYPPAHΔ” in 17, and in this case the font is set from the last character as described above. Therefore, “ΔHAPPYΔBIRTHDAY'88” is displayed on the print.
(Note: If the year of the calendar is 88, yL = yH =
The font is specified so that the display of 8) is displayed.
Similarly, if the message counter is 1, "MERRY △
CHRISTMAS'yHyL ", if the value of the counter is 2," ΔΔCONGRATULATIONS! "If the value of the counter is 3," Δ ... ΔIΔLOVEΔYou! ", If the value of the counter is 4," Δ ... ΔTHANGΔYou! " Is imprinted. It will be understood from FIG. 10 that the "year" of the date data is not imprinted when the counter has three values of 2, 3 and 4. The imprint position offset value is 0 when the message counter is 1,
When it is 2, it is set to 1 when it is 3, it is set to 3 when it is 4, and it is set to 4 when it is 4, and it is configured so as to be substantially at the center of the imprinting position.

When the mode is discriminated and the font is designated as described above, the DATSET subroutine is called in step # 013 to output the actual font.

The DATSET subroutine is described by the flowchart of FIG. First, in step # 100, the first digit (the lowest digit on the print) of the imprint D
Middle digit of iGiT0 font specification address; PD0
The contents of H are loaded into DACCM, the middle digit of a 12-bit (4 bits × 3) counter that specifies an address when referring to the data table in the ROM.

Next, in step # 101, similarly, the upper digit of the font designation address; the content of PDOH is also loaded into the upper digit of the data counter; DACH, and then the FNTOUT subroutine for actually outputting the font is called. If you want to output "A" font with DiGiTO, DAC for DACM and DACH respectively.
H = 7 and DACM = A.

Next, the FNTOUT subroutine will be described with reference to the flowchart of FIG. First, step # 20
The lower digit (DACL) of the data counter is set to 0 at 0, and then at step # 201, the D-F / F. The reset of 22 is released by setting OPLARST = L.

Next, at # 202, the state of the imprint reversing switch 82 is discriminated, and if the switch is off, RV is detected.
Since the input of the port becomes HI level, step # 20
3 is a data counter; the lower 4 bits (DACL) which is the contents of the ROM address data designated by the DAC are OPL
Output to EDL port. That is, the case of outputting "A" by the above-mentioned DiGiT0 will be described. Since the contents of the data counter; DAC is H'7A0, the lower 4 bits of the data of the ROM address are B'1111 (the upper left end of FIG. 8). (Refer to the font diagram of "A").

Next, in step # 204, the upper 4 bits (DACH), which is the content of the data stored in the ROM address designated by the data counter, is output to the OPLEDH port. (In the case of the font "A" mentioned above, B'0
011). Further, in step # 205, the lower 4 bits of the ROM address designated by the data counter with 8 added to the lower digit of the data counter; DACL is output to the OPLFDH port. In case of “A” DAC =
It becomes H'7A8 and the lower 4-bit data becomes B'0000. Although the first 3 bits are not connected to the output port in the embodiment, the font data is output to the LED lighting control output ports (OPLEDL to DPLEDH) in steps # 203, # 204 and # 206. Become. In the sequence, 7 is subtracted from DACL in step # 207 and the rising edge input of the imprinting pulse is waited in step # 208. When the rising edge enters the D-F / F22 clock, the Q output becomes H (iPEDECT = H), and the process proceeds to step # 209 to reset the D-F / F. Here, the actual lighting time of the LED is as shown in the timing chart of FIG.
(L0-3, LEDM0-3, LEDH0) and the inversion signal of the imprinting pulse and the imprinting enable signal are the logical sum (see FIG. 1) of the LED.
The lighting period is limited to the low level period of the imprinting pulse (overbar DCLK (hereinafter referred to as "-DCLK") for the bit output by 1 to the font output port. Also, step # 208 and DF / F.22. The reason why the rising edge of the imprinting pulse (-DCLK) is detected is to detect the end of LED lighting of one line of the font and set the next font data.

Next, in step # 210, it is determined whether the lower digit of the data counter; DACL has become 8. If it is 8 or less, the processing in step # 201 and thereafter is performed again. That is, after that, the lower digit of the data counter; 8 is added to DACM (# 205) and 7 is subtracted (# 207) in the previous flow so that the next line of the font is output. Data counter; DAC will specify the data of the next column. In case of "A", (DAC) =
It becomes H'7A1.

When the output of the last column is completed (H'7A7 and H'7AF in the case of "A") DACL
Becomes 8 and the process branches at step # 210 to the subroutine FN.
End TOUT and return.

On the other hand, in step # 202, the imprint reversing switch 82
Is determined to be ON, the R specified by the DAC is determined in # 211.
Lower 4 bits (DACL) of the contents of OM address data
Each bit is inverted and then output to the OPLED port at # 212. Similarly, the bit of DACH is inverted at # 213, and the bit content of (DACL + 8) is inverted at # 216. As a result, the inverted data of the contents of the font data shown in FIG. 6 is output as a font.

The control after # 207 is performed by the inversion switch 82.
Is the same as when is off. When the output of the imprinted font for one character is completed in this way, DACL = 8, so that the FOTOUT subroutine is exited from step # 210 and the font of the next character (DiGiT1) is output from step # 103. Subsequent output of each character is DiG
Similar to iT0, the font start address of each character is set in the DATSET subroutine and FN is set.
The font is actually output to the LED output port by calling the TOUT subroutine.

Here, the last column of the font of each character, (A
Since 7) contains a blank pattern for one column (when DACL = H'7 or H'F), one dot blank is inserted between each imprinted character. In the case of the inverted output, the blank is represented by lighting and the same applies.

Now, the final character (DiGiT17)
When the output is completed, the routine returns from the DATSET subroutine, and the wind motor 13 is returned in step # 014 of FIG.
Wait for the image to stop and the imprinting to be disabled,
When it is disabled, it waits for the next imprinting again (see step # 007).
The entire imprinting sequence is completed.

In the embodiment of FIG. 3, when the imprinting mode is calendar, only the order of "year, month, day" is prepared, so that the year digit display section 15a, the month digit display section 15b,
Although only the day digit display portion 15c and the single quotation mark 15e portion indicating the year display are provided, other segments may be added for displaying the English month, time, and the like. Then, in the apparatus of the present embodiment, when the imprinting is set to the message mode (second mode) in the above operation, the apparatus automatically sets the date data imprinting mode (first mode) after the camera is released. It is characterized by returning to.

That is, in the apparatus of this embodiment, as described above, the trailing edge is input to the one-shot pulse circuit 66 at the timing when the winding operation is completed after the camera release. Since the one-shot pulse circuit 66 generates a pulse for a predetermined time, at this time the cancel switch 80
Is on (normal), if the Q output of the D-F / F 63 is H, the output of the OR gate 65 is also H and the D-F / F. 6
3 is reset. When reset, the DF / F. 6
Since the Q output of 3 becomes H, the iPCAL input of the microcomputer 1 becomes H and the imprint mode becomes the date mode. Since this Q output is also input to the LCD driver, 14, the external LCD display is also switched to the content corresponding to the mode.

However, if the cancel switch 80 is turned off (the mode automatic return is canceled), the above automatic return is not performed, and a plurality of images can be taken in the same message imprinting state. The cancel switch 80 may be interlocked so that the power is turned on / off or the film is replaced so that the cancel switch 80 is normally turned on. Second Embodiment In the first embodiment, the switching between the first mode and the second mode is configured to be switched by a switch, but it may be configured to be linked to the switching of the calendar and message imprinting. It is possible.

FIG. 13 shows an overall configuration diagram of the second embodiment. D that latches the switching state of calendar and message
This can be configured by using the Q output of the -F / F 63 as a signal for switching the imprinting mode.

As a result, when the date is imprinted, the imprint content can be made inconspicuous in the first mode, and in the case of the message imprint, the imprint content can be made conspicuous in the second mode.

Third Embodiment In the third embodiment, the switching between the first mode and the second mode is automatically switched depending on the brightness of the portion where the image is printed.

FIG. 14 shows an overall configuration diagram of the third embodiment.
In FIG. 14, 89 is an optical sensor composed of a photo diode or the like for detecting the exposure brightness at the data imprinting position in the photographing screen, and 90 is the photocurrent output from the optical sensor 89 and converted into a corresponding voltage value. Photocurrent detection circuit.
Reference numeral 91 is a comparator, and the input of the photocurrent detection circuit is input to the − input and the predetermined voltage (Vref) is input to the + input.

The operation will be described below. The exposure brightness of the film data recording position is high,
When the input is higher than the predetermined voltage (Vref), the comparator 9
The output of 1 becomes the LQ level and is applied to the RV port input of the microcomputer 1.

It has already been explained that the microcomputer 1 is configured to be in the imprint inversion mode (second mode) when LQ is input to the RV port.

[0064]

As described above, according to the data imprinting apparatus of the present invention, the following effects can be obtained. If you want to make the contents of the data imprint stand out on the photographic print, you can reverse the imprint as necessary to make it stand out. In the case of a photograph that you do not want to stand out, ordinary imprinting is possible, and it is possible to satisfy the two requirements. When the second mode is selected, since at least one dot is added to both ends of the imprinted character to indicate the imprinted end, the ringing of the character in the second mode becomes clear.
