For example, microcomputer 15 is controlled at the high level identical with power lead 18 with first control input end 63, and the current potential of PNP transistor 71 base terminals is in identical level with power lead 18, and PNP transistor 71 becomes closed condition.At this moment, close any switch 36 of second multi-channel modulation converter 13, light emitting diode D02, the D04 that is connected with this switch 36 ..., D16 gate terminal of negative electrode and capacitor 74, FET75 be connected.Light emitting diode D02, D04 ..., D16 is according to being subjected to the light light quantity to produce voltage.

Fig. 4 is the key diagram of expression twilight sunset image 90 1 examples.The represented twilight sunset view data 90 of Fig. 4 is raw column data of 16 row * 19 row.Accommodate [0] or [1] as numerical value in each key element of ranks.
First row is the light-emitting data of the first light emitting diode D01, second row is the light-emitting data of the second light emitting diode D02, the third line is the light-emitting data of the 3rd light emitting diode D03, fourth line is the light-emitting data of the 4th light emitting diode D04, fifth line is the light-emitting data of the 5th light emitting diode D05, the 6th row is the light-emitting data of the 6th light emitting diode D06, below, the 7th same row is to the light-emitting data of the 16 behavior the 7th light emitting diode D07 to the 16 light emitting diode D16.
CPU83 is by the order of every row, twilight sunset view data 90 is write I/O port 81, when reverse write-in program device 1 from visual angle with the people that watches it attentively, by left when right-hand the shaking, when promptly shaking by the people's who shakes it right left, CPU83 is by hereinafter described control, risen in order by the column data of Fig. 4 leftmost side, writes I/O port 81 1 row row.I/O port 81 makes the column data that writes and clock signal same period, to first multi-channel modulation converter 11 and 13 outputs of second multi-channel modulation converter.First multi-channel modulation converter 11 and second multi-channel modulation converter 13 are closed the switch corresponding with column data [1] 33,36, and, open the switch corresponding 33,36 with column data [0].Closed switch 33,36 light emitting diode D01, D02 ..., D16 is luminous.Thus, at [GO] literal that has formed in the space as the twilight sunset image that shakes of reverse write-in program device 1.
It seems from the people who watches reverse write-in program device 1 attentively, the reverse write-in program device 1 that shakes to the right shake direction turn back the beginning shake to the left, the column data of CPU83 rightmost side from Fig. 4 writes the I/O port in order rows ofly.Light emitting diode D01, D02 ..., D16 is luminous by the order opposite with previous situation.Oppositely write-in program device 1 shakes the same period with this, carries out above-mentioned control repeatedly.Thus, whenever reverse write-in program device 1 from right to left, perhaps shake from left to right, shaking in the space of this reverse write-in program device 1, form [GO] literal as the twilight sunset image.
Corresponding in each row of twilight sunset view data 90 with speed integrating value.EEPROM86 preserves this speed integrating value and twilight sunset view data 90 simultaneously.Will with the speed integrating value of the corresponding setting of each row, as described later, compare with the speed integrating value of shaking the position integrating corresponding to reverse write-in program device 1.The speed integrating value of each row is greater than the integrating value of left side adjacent column among Fig. 4.Among Fig. 4 the speed integrating value of rightmost side row be on the occasion of, poor between the speed integrating values of adjacent 2 row all equates in all row make up.Difference between the speed integrating value of these adjacent 2 row also can have nothing in common with each other by different row combinations.
Then, the integral body control to reverse write-in program device 1 describes.
Powered-down switch 5, power lead 18 links with battery 17.Other circuit components of microcomputer 15 are provided by the electric power entry into service that provides from this power lead 18.The CPU83 reading control program 89 of microcomputer 15 is also carried out.Fig. 5 is the process flow diagram of the expression main program that CPU83 moved.
CPU83 affirmation mode (ST1).Specifically, CPU83 reads the value of the memory buffer of the I/O port 81 corresponding with mode selector switch 6.
When the value of this memory buffer was [1] (potential level is a high level), CPU83 was judged to be read mode, carried out read step (ST2).Read step is the step that usefulness is read in control.When the memory buffer value was [0] (potential level is a low level), CPU83 was judged to be light-emitting mode, carried out luminous step (ST3).Luminous step is the step of control illuminating.
Fig. 6 is the process flow diagram of the detailed step of the luminous step of expression (ST3).
At luminous step (ST3), CPU83 carries out the initial setting step.
Set in the early stage in the step, CPU83 carries out the setting of light-emitting mode and handles (ST11).Specifically, CPU83 is controlled at low level with first control input end son 43 of first driving circuit 12 and first control input end 63 of second circuit 14.CPU83 is controlled at high level with second control input end son 44 of first driving circuit 12 and second control input end 64 of second circuit 14.Light emitting diode D01, D02 ..., the D16 negative electrode current potential be power supply potential to be carried out the current potential that dividing potential drop obtains by 2 resistive elements 46,47 (66,67).The input terminal 31,34 of first multi-channel modulation converter 11 and second multi-channel modulation converter 13 is connected with power lead 18.
After the setting of finishing light-emitting mode was handled, CPU83 was according to the value of speed pickup 16, and the velocity amplitude integrating that begins to be used for the position of particular inverse write-in program device 1 is handled (ST12).Specifically, CPU83 will be in the value of speed pickup 16 by the 0 reference position A that shakes to start with to the position of the reverse write-in program device 1 on the time point that changes, the processing that adds of the velocity amplitude of commencing speed sensor 16 outputs.This adds and handles the Integral Processing that is equal to velocity amplitude.Speed integrating value is with the corresponding setting in position of reverse write-in program device 1.When reverse write-in program device 1 shake the position when identical, speed integrating value is for being close to the value that equates.
When the value of speed pickup 16 was 0, promptly reverse write-in program device 1 was in and stops, and perhaps reverse write-in program device 1 shakes the opportunity that direction (sense of rotation) is switched.Oppositely be asynchronous memory buffer opportunity of reading of shaking opportunity that direction switches and CPU83 of write-in program device 1.Therefore, might the buffer-stored value not be 0 yet, be positive velocity amplitude by the negative velocity value transform suddenly.In the output valve of speed pickup 16 values is not that CPU83 can begin velocity amplitude is added at velocity amplitude on the occasion of the initial time point that changes under the 0 ground situation about changing like this.At this moment, oppositely write-in program device 1 position that begins to shake and the integrating velocity amplitude reference position A that is at 0 o'clock is inconsistent.But, being under the identical situation of shaking the position at reverse write-in program device 1, speed integrating value is identical numerical value.As the light emitting control of being undertaken by CPU83 is not in-problem.
CPU83 to integrating speed integrating value, compare (ST13) with the speed integrating value of the corresponding preservation of each row of twilight sunset view data 90 of EEPROM86.These are worth consistent, and CPU83 is corresponding subsidiaryly to be had and the corresponding to speed integrating of the speed integrating value value that is obtained by the EEPROM86 integrating, read a twilight sunset view data 90 (ST14) of itemizing the position.Specifically, CPU83 just compares in the speed integrating value of integrating speed integrating value and the CPU83 that is kept at EEPROM86, when CPU83 just when the speed integrating value of the speed integrating value of integrating and preservation is consistent, the corresponding subsidiary column data of speed integrating value that will be consistent with this writes the memory buffer (ST14) of I/O port 81.
The clock signal action same period of CPU83 and clock 82.Therefore, it is inconsistent in the speed integrating value of the speed integrating value of integrating and preservation that CPU83 can take place, and the situation of increase and decrease to some extent.Under the situation that speed integrating value is added, when this integrating value during greater than next speed integrating value, CPU83 will write the memory buffer of I/O port 81 with this corresponding column data of speed integrating value that exceeds; Speed integrating value is being subtracted under the situation of calculation, and when this integrating value during less than next speed integrating value, CPU83 will write the memory buffer of I/O port 81 with this corresponding column data of speed integrating value that exceeds.
I/O port 81 is with the column data of write buffering memory, to first multi-channel modulation converter 11 and 13 outputs of second multi-channel modulation converter.First multi-channel modulation converter 11 and second multi-channel modulation converter 13 are closed corresponding to the switch 33,36 of value for the memory buffer of [0].Light emitting diode D01, D02 ..., among the D16, the light emitting diode that is connected with the switch 33,36 of having closed carries out luminous.
CPU83 judges stop (ST15) of reverse write-in program device 1.Specifically, for example CPU83 is according to the value of the memory buffer of I/O port 81, judges that whether the state that value in memory buffer is lower than setting continues to take place, and judges perhaps whether speed integrating value has not changed.CPU83 stops to be judged to be end of a period under any one or more of situation in the Rule of judgment satisfying these.The processing of CPU83 is returned to master routine shown in Figure 5.
Under the situation that oppositely write-in program device 1 does not stop, CPU83 carries out the step (ST13) of comparison speed integrating value repeatedly, extracts the step (ST14) of new row out and stop determination step (ST15) from twilight sunset image 90.The memory buffer of I/O port 81, often be written into the corresponding subsidiary column data that the speed integrating value consistent with speed integrating value after the CPU83 integrating is handled arranged, perhaps, write the corresponding subsidiary column data that the most approaching speed integrating value of speed integrating value after handling with the CPU83 integrating is arranged.As long as reverse write-in program device 1 in specialized range about, rock back and forth, perhaps as long as reverse write-in program device 1 press certain orientation rotation or come and gone rotation, CPU83 does not stop with regard to then not being judged to be, and proceeds light emitting control.
If oppositely the position of shaking of write-in program device 1 changes, the speed integrating value of integrating and the column data that is written in the memory buffer of I/O port 81 then can change.When reverse write-in program device 1 same when shaking the position, the speed integrating value of integrating is close to and equates, is written into same column data in the memory buffer of I/O port 81.
Oppositely write-in program device 1 shakes by continuing and coming and going within the specific limits, can form the literal of [GO] continuously.
Fig. 7 is the routine key diagram of expression by the twilight sunset image of this light-emitting mode control formation.Fig. 7 is the twilight sunset image that is obtained by twilight sunset view data shown in Figure 4.The literal [A] of Fig. 7 left side expression is that the speed integrating value of CPU83 integrating is [0], the oppositely reference position of write-in program device 1.
For example, under the situation that oppositely the every interval of waving angle about 5 of write-in program device 1 is spent, the every increase and decrease 10 of speed integrating value of CPU83 integrating.Under the situation that reverse write-in program device 1 is shaken to Fig. 7 right side by reference position A, the CPU83 integrating value that gathers way.In the twilight sunset view data 90 of Fig. 4, the difference between the speed integrating value of 2 adjacent column data is 10.By (=5 degree * (19-1)) above waving angle shakes with 90, oppositely write-in program device 1 is according to the twilight sunset view data 90 of [GO] shown in Figure 4, expression [GO] literal shown in Figure 7 in the space of reverse write-in program device 1 swing range.
CPU83 judges the speed integrating value of reverse write-in program device 1, and promptly as the position of shaking of reverse write-in program device 1 displacement, CPU83 will the column data corresponding with judging the position writes the memory buffer of I/O port 81.When reverse write-in program device 1 be in same when shaking the position, oppositely light emitting diode D01, the D02 of write-in program device 1 ..., D16 carries out luminous according to same column data.Even oppositely write-in program device 1 is not to shake with certain velocity-stabilization ground, perhaps is not stably to shake within the specific limits, also the twilight sunset pictograph that identical position forms [GO] can be close to.
Fig. 8 is the process flow diagram of the detailed step of expression read step ST2.
In read step ST2, CPU83 carry out quantity be equal to 16 times of light emitting diode number read processing (ST21, ST22 ..., ST36).CPU83 carries out by the first light emitting diode D01 and plays in order the processing of reading till the 16 light emitting diode D16, and the 16 light emitting diode D16 reads after processing finishes, and CPU83 detects the state of mode selector switch 6.When the reading treatment S T36 and finish of the 16 light emitting diode D16, mode selector switch 6 is under the situation of read mode with external schema, and promptly this example 1 is under the situation of light-emitting mode, and CPU83 finishes to read processing (ST37).CPU83 gets back to the main program of Fig. 5.
Fig. 9 be expression each light emitting diode D01, D02 ..., D16 read processing (ST21, ST22 ..., ST36) the detailed step process flow diagram.
Each light emitting diode D01, D02 ..., the reading in the processing of D16, CPU83 carries out the initial setting step.
At this, describe with the example that is read as of first light emitting diode.First control input end son 43 and second control input end 44 of first driving circuit 12 that CPU83 will be connected with first light emitting diode (below be designated as the sensitive side driving circuit) is controlled at high level (ST41, ST42).CPU83 is controlled at low level at first control input end 63 with second driving circuit 14 of opposite side (below be designated as the emission side driving circuit), simultaneously, second control input end 64 is controlled at high level (ST43, ST44).The control signal that CPU83 will close the 1st switch connects first multi-channel modulation converter 11 (below the be designated as the sensitive side multi-channel modulation converter) output (ST45) of side to the 1st light emitting diode.The control signal that CPU83 will close the 2nd switch is to second multi-channel modulation converter 13 (below be designated as the emission side multi-channel modulation converter) output (ST46).
After finishing initial setting, CPU83 carries out photometry and handles (ST47).Figure 10 is the process flow diagram of expression photometry treatment S T47 detailed step.
In photometry was handled, CPU83 made second control input end 44 of sensitive side driving circuit, changed (ST61) by high level to low level.The anode of the 1st light emitting diode becomes earthing potential.Put aside under the situation of electric charge at the capacitor 54 of sensitive side driving circuit, applied voltage in a clockwise direction to the 1st light emitting diode.The electric charge of capacitor 54 discharges by the 1st light emitting diode.Second control input end 44 of sensitive side driving circuit for example is controlled in low level in the time about 1ms, and capacitor 54 discharges fully like this, and the negative electrode of the 1st light emitting diode becomes earthing potential.Do not have electric current to flow between the source terminal of the FET55 of sensitive side driving circuit and the drain terminal, the lead-out terminal 45 of sensitive side driving circuit becomes high level, and capacitor 54 resets.
For example in the time about 1ms, second control input end 44 of sensitive side driving circuit is controlled at (ST62) after the low level, CPU83 switches to high level (ST63) with this second control input end 44.Second control input end 44 switches to high level by low level, the current potential of the anode potential of the 1st light emitting diode for being undertaken obtaining after the dividing potential drop by 46,47 pairs of power supply potentials of 2 resistive elements.The 1st light emitting diode produces and is subjected to the corresponding voltage of light light quantity.The voltage of capacitor 54 according to the voltage that the 1st light emitting diode is produced carry out integration waveform change.The current potential of the gate terminal of FET55 according to the voltage that the 1st light emitting diode is produced carry out integration wave form varies.
Figure 11 is the oscillogram of lead-out terminal 45 potential change of expression sensitive side driving circuit.What transverse axis was represented is the time, and what the longitudinal axis was represented is the current potential of lead-out terminal 45.The waveform A of Figure 11 upside is a reading images when being black, the potential waveform of lead-out terminal 45, and the waveform B of Figure 11 downside is a reading images when being white, the potential waveform of lead-out terminal 45.
Under situation shown in Figure 11, when reading images is black, second control input end 44 of sensitive side driving circuit switch to by low level about 70ms that high level rises during in, the current potential of the lead-out terminal 45 of sensitive side driving circuit is reduced to 2.5V by 4.5V, is transition period during this about 70ms.When the image that reads is when white, second control input end 44 switch to by low level about 10ms that high level rises during in, the current potential of sensitive side driving circuit lead-out terminal 45 is reduced to 1.5V by 4.5V.When reading images is grey, during about 10～70ms in, the current potential of circuit output end 45 that sensitive side drives slowly be reduced to a certain current potential between 2.5V and the 1.5V.
The control utmost point of FET55 not with situation that capacitor 54 is connected under, the current potential of the lead-out terminal 45 of sensitive side driving circuit, irrelevant with color of image, during number ms in, moment is reduced between 2.5V and the 1.5V.
Then, CPU83 as shown in figure 10, second control input end 44 with the sensitive side driving circuit is switched to high level and plays about 10ms by low level after, the light emitting diode anode potential that is subjected to light has been changed (ST64) behind about 10ms, read the level (ST65) of the lead-out terminal 45 of sensitive side driving circuit by I/O port 81.CPU83 finishes photometry treatment S T47.
After finishing photometry treatment S T74, CPU83 judges whether the level of the lead-out terminal 45 of the sensitive side driving circuit that this reads is higher than 2.75V (threshold value) (ST48) shown in process flow diagram among Fig. 9.When the level that reads was higher than threshold value, CPU83 was judged to be black, write [1] (ST49) at the 1st row of the twilight sunset view data 90 of EEPROM86; When the level that reads during smaller or equal to 2.75V, CPU83 is judged to be white, writes [0] (ST50) at the 1st row of the twilight sunset view data 90 of EEPROM86.
CPU83 respectively just by the 1st light emitting diode D01, D02 ..., D16 plays each light emitting diode till the 16 light emitting diode D16, respectively execution graph 9 and above-mentioned each light emitting diode D01, D02 shown in Figure 10 ..., D16 read processing.That is to say that CPU83 carries out the individual light emitting diode of n (n is 1 to 16 integer) as photo detector, with the control of the individual light emitting diode of n+1 (n is 1 to 16 integer) as light-emitting component successively by the order of n from 1 to 16.When this processing finished, EEPROM86 preserved the 1 twilight sunset view data 90 of itemizing the position.And, when n was even number, second driving circuit 14 was sensitive side driving circuits, and first driving circuit 12 is emission side driving circuits, second multi-channel modulation converter 13 is sensitive side multi-channel modulation converters, and first multi-channel modulation converter 11 is emission side multi-channel modulation converters.
After including the 1 twilight sunset view data 90 of itemizing the position in EEPROM86, as shown in Figure 8, CPU83 judges whether mode selector switch 6 is switched to read mode pattern in addition, after determinating mode change-over switch 6 was read mode, CPU83 continued read mode.Continuing under the situation of read mode, the side-play amount that reads the position (amount of movement) that CPU83 detects reverse write-in program device 1 (ST38).For example, as shown in Figure 7, CPU83 judges whether moved the distance that is equivalent to 5 degree, if moved the distance of regulation, CPU83 carries out the step of ST21 to ST37.Until mode selector switch 6 be switched to read mode with external schema till, CPU83 carries out ST21 repeatedly to ST37.CPU83 detects reverse write-in program device 1 each trickle amount of movement on one side, Yi Bian repeatedly 1 itemize bit image read processing (ST37).
The user is switched to read mode at mode selector switch 6, for example, reverse write-in program device 1 is placed on as shown in figure 12 the paper.Oppositely write-in program device 1 be light emitting diode D01, D02 ..., D16 is downwards in the face of being placed under the state of paper.The user moves reverse write-in program device 1, and reverse write-in program device 1 is passed through from the top that is documented in [GO] literal on the paper, the CPU83 carries out image read processing, twilight sunset view data 90 shown in Figure 4 is kept at EEPROM86.
And CPU83 can the twilight sunset view data 90 when mode selector switch 6 is switched to light-emitting mode write EEPROM86.In this case, write the preceding twilight sunset view data 90 of EEPROM86 and can be kept at RAM84 temporarily.
EEPROM86 respectively is listed as the speed integrating value of corresponding preservation mutually with mutual corresponding being provided with twilight sunset view data 90 in the storage area of twilight sunset view data 90 each row, and before reading, can fix preservation in advance.Whether in this case, adopt whether the velocity product score value that detects by CPU83 is setting, promptly whether this value is [10] in Fig. 4, replace detecting having moved being equivalent to 5 distances of spending in Fig. 8 process flow diagram.
CPU83 when reading, the value of integration is above-mentioned when reading speed pickup 16, and can write EEPROM86 with these integrated values as the speed integrating value corresponding with each row.
As mentioned above, the reverse write-in program device 1 of example 1 reads the writings and image that is documented on paper etc.The reverse write-in program device 1 of example 1 is formed the image that reads as the twilight sunset image.
And, because the reverse write-in program device 1 of example 1 be with make light emitting diode D01, D02 ..., the luminous circuit of D16 and the combination of circuits dual-purpose of accepting these light be 1 first driving circuit 12, or the combination dual-purpose is 1 second driving circuit 14, so just can pass through littler circuit scale, control a plurality of light emitting diode D01, D02 ..., D16 luminous and be subjected to light.The reverse write-in program device 1 of this example 1 be provided with light emitting diode D01, D02 ..., D16 and be separately positioned on multi-channel modulation converter 11,14 between 2 driving circuits 12,14, according to the twilight sunset view data output control signal that flows to these 2 multi-channel modulation converters 11,14.The quantity of the driving circuit of the reverse write-in program device 1 of this example 1 (this example is 2) is the quantity (this example is 16) that is less than light emitting diode.The reverse write-in program device 1 of example 1, needn't directly be connected as each light emitting diode with driving circuit, setting equals the driving circuit of light emitting diode quantity with quantity, and the reverse write-in program device 1 of this example 1 only has 2 groups of driving circuits and multi-channel modulation converter.Oppositely write-in program device 1 be small-sized, light weight, be easy to shake.
But first control terminal 41 of first driving circuit 12 and being connected of capacitor 54, and the capacitor 74 that connects between first control terminal 61 of second driving circuit 14 and the ground wire 19 have following content.
The first, by connect capacitor 54 and capacitor 74 on this position, the voltage excessive variation when reading on the lead-out terminal 45,75 is compared with the variation of exporting with respect to the light emitting diode that is subjected to the light light quantity, is slowly.Even the time for reading point at image is offset a little, the output of light emitting diode takes place under the situation jumpy betwixt, and the change in voltage on the lead-out terminal 45,75 that is used to judge also can tail off.The reverse write-in program device 1 of example 1 comes the white black of process decision chart picture by the judgement after stable, and can carry out binaryzation.
Under the situation that does not have capacitor 54,74, the current potential of lead-out terminal 45,65 is the potential change under steady state (SS) at once.CPU83 must carry out the judgement of binaryzation according to the value under the steady state (SS).Under steady state (SS), as shown in figure 11, the potential difference (PD) between the reading potential of white image and the reading potential of black image is about about 1V.The absolute value of the absolute value of the reading potential of white image and the reading potential of black image is the color according to paper, the concentration of printing ink, and other read environmental factor, in 0.5～1V left and right sides simple change.So, consider that these general patterns read the variable of environment, under steady state (SS), between the reading potential of the reading potential of white image and black image, the binaryzation threshold value suitably is set is difficult to.Monochrome determining under the steady state (SS) might can't be provided with suitable threshold as the black and white of suitable judgement image.
To this, as implementing form 1, between first control terminal 41,61 and ground wire 19, connect capacitor 54,74, on the lead-out terminal 45,65 excessive variation of voltage when reading light emitting diode be subjected to slowly carry out for the light light quantity.In this transition period that slowly changes,, can guarantee that potential difference (PD) maximum between the black and white is about about near 3V (among Figure 11 the 10ms) by reading the voltage of lead-out terminal 45,65.Even because of reading environmental factor change about 0.5～1V takes place, also the binaryzation threshold value can be set definitely, well the black and white of image is judged, finish binaryzation.
The second, on first control terminal 14 by capacitor 54 and capacitor 74 being connected first driving circuit 12 etc., CPU83 read to light emitting diode D01, D02 ..., the magnitude of voltage behind the voltage integrating meter that produces of D16.The stability of reverse write-in program device 1 reading images of this example 1 is very high.
The situation that compares reading images shown in the reading images situation shown in Figure 13 (A) and Figure 13 (B), oppositely write-in program device 1 is moved by the left side of figure to the right along the horizontal line of dotted line grid.Each light emitting diode D01, D02 ..., D16 moves between 2 horizontal lines.The individual light emitting diode of D (n-1), D (n) light emitting diode and the individual light emitting diode of D (n+1) have only been represented among Figure 13.CPU83 reads the value of the lead-out terminal 45 (65) of sensitive side driving circuit at the time point that the ordinate of reverse write-in program device 1 and dotted line grid overlaps.Figure 13 reads at time point T1, T2, T3, T4, T5.
As the situation result relatively that coincides of the dotted line grid with respect to the oblique boundary ab of black white image, each light emitting diode D01, D02 among Figure 13 (A) ..., D16 read each light emitting diode D01, D02 among position and Figure 13 (B) ..., D16 the position of reading compare, be offset a little to the top of drawing.For example, D (n-1) light emitting diode is under the situation of Figure 13 (A), and T1 reads black at time point, and T2 reads white at time point, under the situation of Figure 13 (B), is to read black at time point T1 for this, also reads black at time point T2.
Between first control terminal 41 and ground wire 19, be not connected with under the situation of capacitor 54, perhaps between first control terminal 61 and ground wire 19, be not connected with under the situation of capacitor 74, lead-out terminal output light emitting diode D01, the D02 of sensitive side driving circuit ..., D16 the instant value that is subjected to the light light quantity.After CPU83 reads this instant value, use in the judgement of binaryzation.In reading Figure 13 (A) under the situation of image, the twilight sunset view data 90 of Figure 14 (A) is kept at EEPROM86; In reading Figure 13 (B) under the situation of image, the twilight sunset view data 90 of Figure 14 (B) is kept at EEPROM86.In each ranks of Figure 14, first row is the reading of data of D (n-1) light emitting diode, and second row is the reading of data of D (n) light emitting diode, and the third line is the reading of data of D (n+1) light emitting diode; First row are the reading of data on the time point T1, and secondary series is the reading of data on the time point T2, and the 3rd row are the reading of data on the time point T3, and the 4th row are the reading of data on the time point T4, and the 5th row are the reading of data on the time point T5.
[1] and the boundary position between [0] of Figure 14 (A) medium afterglow view data 90 are to be different from [1] of Figure 14 (B) medium afterglow view data 90 and the boundary position between [0].Like this, the difference of boundary position between [1] and [0] means that the position of the twilight sunset image that forms thus also is different with profile.
To light emitting diode D01, D02 ..., D16 the light light quantity instant value that is subjected to carry out under the situation of binaryzation, only stagger by making facing to the position of reading of the reverse write-in program device 1 of image, the position of twilight sunset image changes, and the profile of twilight sunset image also changes.In a word, image read stability bad.
With respect to this point, between first control terminal 41,61 and ground wire 19, be connected with under the situation of capacitor 54,74, by in the lead-out terminal 45,65 as lead-out terminal output light emitting diode D01, the D02 of sensitive side driving circuit ..., D16 the integrated value that is subjected to the light light quantity.That is to say, for example at time point T2, by lead-out terminal output with corresponding to time point T1 in the time point T2 interval light emitting diode D01, D02 ..., D16 is subjected to the value that is subjected to light light quantity total amount behind the light.After CPU83 reads these integrated values, be used for the judgement of binaryzation.In Figure 13 (A) under the situation of reading images, the twilight sunset view data 90 of Figure 15 (A) is kept at EEPROM86; In Figure 13 (B) under the situation of reading images, the twilight sunset view data 90 of Figure 15 (B) is kept at EEPROM86.In each ranks of Figure 15, first row is that reading of data, second row of D (n-1) light emitting diode is the reading of data of D (n) light emitting diode, and the third line is the reading of data of D (n+1) light emitting diode; First row are the reading of data on the time point T1, and secondary series is the reading of data on the time point T2, and the 3rd row are the reading of data on the time point T3, and the 4th row are the reading of data on the time point T4, and the 5th row are the reading of data on the time point T5.
[1] and the boundary position between [0] of Figure 15 (A) medium afterglow view data 90, with [1] of Figure 15 (B) medium afterglow view data 90 and the boundary position between [0] is consistent, [1] and the boundary position unanimity between [0] because, so the twilight sunset view data of Xing Chenging also is identical thus.Even stagger to some extent in the position of reading of the reverse write-in program device 1 of image relatively, the profile of twilight sunset image also is identical (consistent).
To light emitting diode D01, D02 ..., D16 the light light quantity integrated value that is subjected to carry out under the situation of binaryzation, even oppositely stagger to some extent in the position of reading of write-in program device 1, also can read identical twilight sunset view data 90, form identical twilight sunset image.In a word, the stability that reads of image has obtained improvement.
Even between first control terminal 41 and power lead 18, be connected with capacitor 54,74,, also can obtain the effect identical with example 1 even between first control terminal 61 and power lead 18, be connected with capacitor 54,74.
Example 2
It is identical with the hardware formation of 1 time reverse write-in program device 1 of example that the hardware of the reverse write-in program device 1 of the invention process form 2 constitutes.Oppositely each of write-in program device 1 and example 1 inscape of the same name is used prosign, and omits the synoptic diagram and the explanation of reverse write-in program device 1 hardware formation.In the reverse write-in program device 1 of the invention process form 2, the control program 89 of light-emitting mode is identical in the reverse write-in program device 1 of the control program 89 of light-emitting mode and the invention process form 1.Omit the process flow diagram and the explanation of light-emitting mode at this.
Light emitting diode D01, D02 ..., D16 is little power consumption, and can sends the circuit component of high-luminance light.Light emitting diode D01, D02 ..., D16 to light emitting diode D01, D02 ..., D16 head direction sends the light of high brightness.Light emitting diode D01, D02 ..., if the brightness of D16 plays skew to some extent by crown direction, will sharply reduce.
Therefore, as shown in Figure 1, with light emitting diode D01, D02 ..., D16 be one row be arranged under the situation of reverse write-in program device 1 leading section 4, make all light emitting diode D01, D02 ..., the Luminance Distribution when D16 is luminous, approximately be equal to Luminance Distribution shown in Figure 16.In a word, each light emitting diode D01, D02 ..., D16 the brightness of head direction (dotted line direction among Figure 16) uprise, in contrast to this, towards adjacent 2 light emitting diode D01, D02 ..., the brightness between the D16 lowers.
So, in read mode, for example, even will make the 4th light emitting diode D04 luminous, be subjected to the level of the lead-out terminal 45 of the sensitive side driving circuit under the situation of light by the 3rd light emitting diode D03, with make the 3rd light emitting diode D03 luminous, be subjected to the level of the lead-out terminal 65 of the sensitive side driving circuit under the situation of light by the 4th light emitting diode D04, even as the parts that are equal to the paper that reflects this light, consider and be subjected to the different influence in head direction position and according to the high light of head direction, be subjected to the different influence of image state at random, guessing this can become different level certainly.
With respect to this, consider received by each light emitting diode D01, the D02 of Figure 16 ..., D16 the catoptrical situation that partly produces of the paper of each centre position correspondence, guess and make the level that the 4th light emitting diode D04 is luminous, be subjected to the sensitive side driving circuit lead-out terminal 45 under the light situation by the 3rd light emitting diode D03, with make the 3rd light emitting diode D03 luminous, be subjected to the level of the sensitive side driving circuit lead-out terminal 65 under the light situation by the 4th light emitting diode D04, be same level substantially.Opposite which is correct in guessing in order to confirm these 2, and the inventor tests, and the result is that 2 level are essentially identical level.The reverse write-in program device 1 of example 2 has utilized this affirmation result.
Figure 17 is the process flow diagram of detailed step of the read step of expression the invention process form 2 times reverse write-in program devices 1.
CPU83 carries out initial setting step (ST71).Specifically, CPU83 is controlled at low level with first control input end 63 of second driving circuit 14, and second control input end 64 is controlled at high level.CPU83 is controlled at high level with first control input end son 43 and second control input end 44 of first driving circuit 12.Even number light emitting diode D02, D04 ..., D16 becomes the state that can carry out light emitting control, odd number light emitting diode D01, D03 ..., D15 becomes the state that can be subjected to photocontrol.
CPU83 closes the 2n-1 switch, then, carries out the control that is used to close the 2n switch.Specifically, CPU83 is with [1] substitution controlled variable n (ST72).CPU83 will make the luminous control signal of second (=2 * 1) light emitting diode D02 to the output of second multi-channel modulation converter 13, and (=2 * 1-1) light emitting diode D01 are subjected to the control signal of light to 11 outputs (ST73) of first multi-channel modulation converter will to make first.
CPU83 carries out photometry and handles (ST74).Specifically, CPU83 reads the level of the lead-out terminal 45 of first driving circuit 12.Level and threshold value (ST75) that CPU83 is relatively read, when the level of the lead-out terminal 45 of first driving circuit 12 that reads is higher than 2.75V (threshold value), CPU83 is judged as black, the twilight sunset view data 90 of EEPROM86 the 1st (=2 * 1-1) row write [1] (ST76).When the level that is read was lower than 2.75V (threshold value), CPU83 was judged to be white, the twilight sunset view data 90 of EEPROM86 the 1st (=2 * 1-1) row write [0] (ST77).
CPU83 will make the 3rd, and (=2 * 1+1) light emitting diode D03 are subjected to the control signal of light to 11 outputs (ST78) of first multi-channel modulation converter, and CPU83 carries out photometry and handles (ST79).Specifically, CPU83 reads the level of the lead-out terminal 45 of first driving circuit 12, the level and the threshold value (ST80) that have relatively read.When the level of the lead-out terminal 45 of first driving circuit 12 that reads was higher than 2.75V (threshold value), CPU83 was judged to be black, write [1] (ST81) at the 2nd (=2 * 1) row of the twilight sunset view data 90 of EEPROM86.When reading level and be lower than 2.75V (threshold value), CPU83 is judged to be white, writes [0] (ST82) at the 2nd (=2 * 1) row of the twilight sunset view data 90 of EEPROM86.
CPU83 1 (ST83) that on controlled variable n, add.CPU83 judges that whether n is smaller or equal to 8 (ST84), when n smaller or equal to 8 the time, CPU83 make light emitting diode D01, D02 ..., among the D16 1 luminous during, (ST73～ST82), number of times repeatedly adds up to 8 times to carry out the processing of reading of 2 binaryzation data repeatedly.When n greater than 8 the time, preserve the itemize binaryzation data of position at EEPROM86 by one of the first light emitting diode D01 to the, 16 light emitting diode D16.
Like this, CPU83 make in order even number light emitting diode D02, D04 ..., when D16 is luminous, by numbering less than odd number light emitting diode D01, the D03 of No. 1, luminous light emitting diode numbering ..., D15 is subjected to light, CPU83 makes and is subjected to the light level binaryzation, generate this odd number light emitting diode D01, D03 ..., D15 twilight sunset view data 90.In addition, CPU83 by numbering less than odd number light emitting diode D01, the D03 of No. 1, luminous light emitting diode numbering ..., D15 is subjected to light, CPU83 is subjected to the light level binaryzation by making, generate this even number light emitting diode D02, D04 ..., D16 twilight sunset view data 90.
When n greater than 8 the time, CPU83 carries out mode decision (ST85).Before the pattern that mode selector switch 6 is switched to beyond the read mode, CPU83 carry out repeatedly above-mentioned 1 itemize bit image read processing (ST72～84).At this moment, oppositely write-in program device 1 moves on paper in order.
Thus, oppositely the user of write-in program device 1 is after switching to read mode with mode selector switch 6, by reverse write-in program device 1 is moved on the paper that records reading images, desirable twilight sunset view data 90 can be saved among the EEPROM86.
As mentioned above, 2 times reverse write-in program devices 1 of example can read the writings and image that is documented on the paper etc. by read mode, generate the twilight sunset view data 90 identical with example 1.
And, 2 times reverse write-in program devices 1 of example in order with even number light emitting diode D02, D04 ..., D16 is controlled at luminance, odd number light emitting diode D01, the D03 before and after the light emitting diode that will be positioned at luminous ..., among the D15 2 are controlled at and are subjected to light state.2 times reverse write-in program devices 1 of example are only by this repeatable operation, just can read odd number light emitting diode D01, D03 ..., the binaryzation data of D15 and even number light emitting diode D02, D04 ..., D16 the binaryzation data.
And then, the reverse write-in program device 1 of example 2 make each lumination of light emitting diode during, be linked in sequence with just at luminous light emitting diode adjacent 2 light emitting diodes and sensitive side driving circuit.The reverse write-in program device 1 of this example 2 needn't switch emission side and sensitive side as example 1, compares with situation about must switch, and reads to handle and oversimplifies.And, 1 reading speed of itemizing the position is increased being equivalent to carry out the required time of this switching.
In example 2, make even number light emitting diode D02, D04 ..., D16 is luminous, make odd number light emitting diode D01, D03 ..., D15 is subjected to light.In addition, though make odd number light emitting diode D01, D03 ..., D15 is luminous, make even number light emitting diode D02, D04 ..., D16 is subjected to light, also can obtain the effect identical with the reverse write-in program device of example 2 times 1.
Example 3
It is identical with the hardware formation of 1 time reverse write-in program device 1 of example that the hardware of 3 times reverse write-in program devices 1 of the invention process form constitutes.Oppositely each of write-in program device 1 and example 1 inscape of the same name is used prosign, and omits the synoptic diagram and the explanation of reverse write-in program device 1 hardware formation.In 3 times reverse write-in program devices 1 of the invention process form in 1 time reverse write-in program device 1 of the control program 89 of light-emitting mode and example the control program 89 of light-emitting mode be identical, so omit the process flow diagram and the explanation of light-emitting mode at this.The basic order of 3 times reverse write-in program device 1 read modes of the invention process form is shown in Fig. 8 process flow diagram.
Figure 18 is the process flow diagram that reads control of each light emitting diode of 3 times reverse write-in program devices 1 of expression example.This process flow diagram be used for by each light emitting diode D02, D03 till the second light emitting diode D02 to the, the 15 light emitting diode D15 ..., D15 read control.
Each light emitting diode D02 shown in Figure 180, D03 ..., the reading in the control of D15, CPU83 carries out initial setting (ST91).For example, be that the 2nd light emitting diode is that example describes with the light emitting diode that reads.In this case, CPU83 first control input end son 63 and second control input end 64 that will connect second driving circuit 14 (below be designated as the sensitive side driving circuit) of the 2nd light emitting diode side is controlled at high level; First control input end 43 of first driving circuit 12 (below be designated as the emission side driving circuit) is controlled at low level, simultaneously, second control input end 44 is controlled at high level.The control signal that CPU83 will close second switch 36 exports second multi-channel modulation converter 13 that connects the second light emitting diode side (below be designated as the sensitive side multi-channel modulation converter) to, exports the control signal of closing the 3rd switch 33 to first multi-channel modulation converter 11 (below be recited as the emission side multi-channel modulation converter).
After finishing initial setting, CPU83 carries out photometry and handles (ST92).The concrete order that photometry is handled is identical with Figure 10.CPU83 handles the light income of the 2nd light emitting diode that is read according to this photometry, judges whether the level of the lead-out terminal 65 of sensitive side driving circuit is higher than 3.5V (high some threshold value) (ST92).When the level of lead-out terminal 65 was higher than high some threshold value, CPU83 was judged to be black, write [1] (ST99) at the 2nd row of the twilight sunset view data 90 of EEPROM86.Under the situation of level smaller or equal to height point threshold value of lead-out terminal 65, whether the level that CPU83 and then judgement are read is lower than 1V (low spot threshold value) (ST94).When the level of lead-out terminal 65 was lower than the low spot threshold value, CPU83 was judged to be white, write [0] (ST100) at the 2nd row of the twilight sunset view data 90 of EEPROM86.
Put smaller or equal to height under threshold value and the situation more than or equal to the low spot threshold value at the level of lead-out terminal 65, CPU83 compares to determine according to these high some threshold values and low spot threshold value, neither is judged as black and does not also judge it is white.The control signal that CPU83 will close the 3rd switch 33 exports emission side multi-channel modulation converter (ST95) to, and then, (ST96) handled in the photometry of carrying out as shown in figure 10.The mean value (ST97) of the level of the lead-out terminal 65 of the level of the lead-out terminal 65 of the sensitive side driving circuit that the CPU83 calculation is newly read and the sensitive side driving circuit that has read judges whether this mean value is higher than 2.75V (middle threshold value) (ST98).Be higher than at mean value under the situation of middle threshold value, CPU83 is judged to be black, the 2nd row in the twilight sunset view data 90 of EEPROM86 writes [1] (ST99), under the situation of mean value smaller or equal to middle threshold value, CPU83 is judged to be white, writes [0] (ST100) at the 2nd row of the twilight sunset view data 90 of EEPROM86.
CPU83 just by till the second light emitting diode D02 to the, the 15 light emitting diode D15, reads processing by each light emitting diode respectively according to process flow diagram shown in Figure 180.For example, reading in the processing of the 3rd light emitting diode D03 grade in an imperial examination odd number light emitting diode, second driving circuit 14 becomes the emission side driving circuit, second multi-channel modulation converter 13 becomes the emission side multi-channel modulation converter, first driving circuit 12 becomes the sensitive side driving circuit, and first multi-channel modulation converter 11 becomes the sensitive side multi-channel modulation converter.
About the first light emitting diode D01 and the 16 light emitting diode D16, CPU83 carries out example 1 shown in Figure 9 reads processing.That is to say that under the situation of the twilight sunset image that generates the first light emitting diode D01, CPU83 makes the first light emitting diode D01 be subjected to light, makes the second light emitting diode D02 luminous.The light level that is subjected to of this moment surpasses 2.75V, and CPU83 is judged to be black; Be subjected to light level smaller or equal to 2.75V, CPU83 is judged to be white.Under the situation of the twilight sunset image that generates the 16 light emitting diode D16, CPU83 makes the 15 light emitting diode D15 be subjected to light, makes the 16 light emitting diode D16 luminous.The light level that is subjected to of this moment surpasses 2.75V, and CPU83 is judged to be black; Be subjected to light level smaller or equal to 2.75V, CPU83 is judged to be white.Finish above read processing after, EEPROM86 preserves the 1 twilight sunset view data 90 of itemizing the position.
Shown in process flow diagram among Fig. 8, CPU83 whenever read 1 itemize the position twilight sunset view data 90, just carry out the affirmation (ST37) of pattern.CPU83 read the 1 twilight sunset view data 90 of itemizing the position repeatedly before the pattern that switches to beyond the read mode.
As mentioned above, 3 times reverse write-in program devices 1 of example read the writings and image that is documented on the paper by read mode, can obtain the twilight sunset view data 90 identical with example 1.
And, 3 times reverse write-in program devices 1 of this example, for from second to the 15 light emitting diode D02, D03 ..., the binaryzation data used of D15, be subjected to the light emitting diode of light, for example when making the light emitting diode D06 that is positioned at light emitting diode D07 one side luminous, can't clearly judge under the situation of black and white, and then obtain opposite side, and judge final black and white according to this mean value just at the mean value of luminous light emitting diode D08.3 times reverse write-in program devices 1 of this example make be subjected to the lumination of light emitting diode of the light emitting diode both sides of light so in order, judge black and white according to this mean value of 2.For example, with the light emitting diode D02, the D03 that are subjected to light ..., the relative position of D15 or this position and a side light emitting diode D01, D02 ..., on the D14 centre position, be positioned under the situation of black and white boundary or be positioned under the situation of gray image, by relatively being subjected to light level and threshold value, also being difficult to carry out correct binaryzation sometimes and judging.Because 3 times reverse write-in program devices 1 of example by with the comparison (weighting) of mean value, judge with the light emitting diode D01, the D02 that are being subjected to light ..., the D15 relative position black and white, even, also can stably carry out correct binaryzation and judge so carry out under the situation of this judgement being difficult to.
And then 3 times reverse write-in program devices 1 of example carry out the situation of determination processing according to the mean value of the lumination of light emitting diode of both sides, only are meant the situation that can't judge high some threshold value and low spot threshold value.Therefore, in 3 times reverse write-in program devices 1 of example, make the situation of the lumination of light emitting diode of both sides, even itemize the reading in the process and have of position, that also majority be back and forth several.In all light emitting diodes, the situation that produces the lumination of light emitting diode of both sides is seldom.Reverse write-in program device 1 by this example 3 reads the time of itemizing the bit image data, compares with reverse write-in program device 1 time of itemizing the bit image data of reading by example 1, can't become very long.Image time for reading in this example 3 no less than the time for reading of example 1 image, can not become problem yet on practice.
In this example 3, combination is by the read step of example 1, generation from the second to the 15 light emitting diode D02, D03 ..., D15 use the binaryzation data time, by using high some threshold value, middle threshold value and these 3 threshold values of low spot threshold value to carry out determination processing, improved the stability and the precision of this judgement.Other can also will make up by the determination processing of these 3 threshold values and the read step of example 2.
Figure 19 is the process flow diagram that the read step of determination processing and example 2 is made up with by these 3 threshold values.In Figure 19,2 photometry determination step ST111, ST112 are equivalent to the processing of step ST92～ST100 among Figure 18.In each step in addition, indicate with 2 times identical symbols of step shown in Figure 17 of example, and omit this detailed description.
Above example 1～3rd, preferable example of the present invention, but the present invention is not restricted to these, in the scope that does not break away from claim of the present invention, can carry out various distortion, change.
In the process flow diagram of Figure 18, when being subjected to light value to be intermediate value, calculate the mean value of 2 level of the light emitting diode that is being subjected to light, relatively mean value and middle threshold value shown in the example 3.Middle threshold value is the mean value of high some threshold value and low spot threshold value.In addition, middle threshold value can also be other numerical value between height point threshold value and low spot threshold value.
Under above-mentioned each example, be positioned at the first light emitting diode D01 and/or the 16 light emitting diode D16 at diode row two ends, be carrying out with from the second to the 15 light emitting diode D02 ..., the D15 different processing of reading.Other can be with only luminous or be subjected to the obsolete light emitting diode of light-emitting mode of light when reading, in abutting connection with the outside that is arranged on the first light emitting diode D01 and/or the 16 light emitting diode D16.Thus, the first light emitting diode D01 and/or the 16 light emitting diode D16 read processing, can with other from the second to the 15 light emitting diode D02, D03 ..., D15 read handle identical.To reach the control program simplification and to dwindle.
In above-mentioned each example, speed integrating value and twilight sunset view data 90 each row are preserved mutually accordingly, by with the comparison of the output of speed pickup 16 being carried out the value behind the integration, carry out the control of light-emitting mode.Other for example can use each column data of twilight sunset view data 90 in order corresponding to certain time interval or certain waving angle.
Under above-mentioned each example, 16 light emitting diode D01, D02 ..., D16 alternately is connected with second multi-channel modulation converter 13 with first multi-channel modulation converter 11 mutually.Other, for example the first light emitting diode D01 is connected with first multi-channel modulation converter 11, the second light emitting diode D02 is connected with second multi-channel modulation converter 13 with the 3rd light emitting diode D03, the 4th light emitting diode D04 is connected with first multi-channel modulation converter 11 with the 5th light emitting diode D05, the 6th light emitting diode D06 is connected with second multi-channel modulation converter 13 with the 7th light emitting diode D07, promptly, except the two ends of diode row, light emitting diode can per 2 alternately be connected with second multi-channel modulation converter 13 with first multi-channel modulation converter 11 mutually.Even under the situation of this variation, also can use each light emitting diode to accept the light that sends in abutting connection with light emitting diode, generate binaryzation twilight sunset view data thus.
Under above-mentioned each example, 16 light emitting diode D01, D02 ..., D16 is by even number and odd number, each have 8 and be connected with second multi-channel modulation converter, 13 these 2 multi-channel modulation converters with first multi-channel modulation converter 11 respectively.Other for example, can make a plurality of light emitting diodes such as 2,4,8,16 be connected on 1 multi-channel modulation converter.Can also can be connected with a plurality of light emitting diodes respectively according to these a plurality of light emitting diodes and different multi-channel modulation converter connections with the multi-channel modulation converter that adds up to more than 3.And the quantity of driving circuit is identical with the quantity of multi-channel modulation converter.Like this,, can make the quantity of driving circuit be less than the quantity of light emitting diode, can reach reverse write-in program device 1 miniaturization and light-weighted purpose by using multi-channel modulation converter.Even under a plurality of light emitting diodes and situation that multi-channel modulation converter more than 3 is connected, identical with above-mentioned example, accept the light that light emitting diode sent of adjacency by each light emitting diode, can generate the twilight sunset view data.
Above-mentioned example has used multi-channel modulation converter 11,13 etc.The read method of example 2 and example 3 is the circuit that do not use multi-channel modulation converter 11,13, is efficient ways under the situation of the quantity of the driving circuit circuit identical with the quantity of light emitting diode promptly.
In above-mentioned each example, after the level value that microcomputer 15 is exported each driving circuit 12,14 carries out binaryzation, as the twilight sunset view data.Other, for example, microcomputer also can carry out the level value by each driving circuit output many-valuedization more than three values.According to the many-valued twilight sunset view data of having changed, make under the situation of each lumination of light emitting diode, for example, driving circuit and multi-channel modulation converter with the figure place equal number of the many-valued data of having changed can be set, first control input end of these a plurality of driving circuits is set at mutually different level, and microcomputer is selected multi-channel modulation converter according to the many-valued data of having changed.Thus, microcomputer can make each light emitting diode be connected with the corresponding mutually driving circuit of each values of many-valuedization data on, formation comprises deep or light twilight sunset image.
Under above-mentioned each example, microcomputer 15 whenever read each light emitting diode be subjected to light level after, will generate the binaryzation data according to this level value.Other, for example, microcomputer 15 can also read one itemize the position light emitting diode be subjected to light level after, generate the binaryzation data of these row.If having read, microcomputer 15 is being set to the light level that is subjected to of light emitting diode during read mode begins till removing from mode selector switch 6, the releasing of this read mode is operated as trigger, then generated the binaryzation data that are subjected to light level according to each light emitting diode.Generate the binaryzation data by releasing operation as trigger, alleviated the processing load of microcomputer in reading process read mode.Even the translational speed of reverse write-in program device 1 rises when reading, microcomputer 15 can be defeated by light emitting diode unexpectedly yet and be subjected to reading of light level, suitably reading images.Reading in all stages after being subjected to light level, can access the distributed intelligence of portrait color.Therefore, microcomputer 15 is weighted calculation to level information around it when each binaryzation data of calculation, and can determine the value of binaryzation data according to the level value of this weighting calculation.The profile of twilight sunset image is difficult to break away from the profile of reading images.
Under above-mentioned each example, in read mode, 1 each and every one the light emitting diode that is subjected to light and luminous light emitting diode are turned round.Other, for example, under the situation of example 1, the quantity that can make the light emitting diode that is in luminance is two 2 adjacent light emitting diodes that are subjected to light, also can be 4, even can be other all light emitting diodes.In addition, under the situation of example 2 and example 3, make a plurality of lumination of light emitting diode that are positioned at light emitting diode one side that is subjected to light, then, can also make a plurality of lumination of light emitting diode that are positioned at the light emitting diode opposite side.
