Abstract

PURPOSE:To obtain a monitoring device which is not affected by variance in time of picture element data by reading picture element data of a solid-state image pickup element by specified number of times and digitally displaying the average value of read picture element data after A-D conversion. CONSTITUTION:In a step 46 mode selector, key input data are read, and in a step 48, the presence of key inputting processing is checked. When there is a mode key input, checking is made as to which mode key is inputted in steps 50-64, and execution mode processing is made according to each mode key input. When there is an ''average'' key input in the stop 64, and average value processing is to be executed, an operator inputs the number of times of picture element data reading from ten-key, and inputs, a ''SET'' key. When the ''SET'' key is inputed, the process proceeds to a step 70. A CPU inputs the average number of times of reading for calculating average value and an average flag is set in a step 72, and averaging processing is made in succeeding execution mode processing.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a monitor device, and particularly to a monitor device that digitally displays signals after analog-to-digital (A-D) conversion of output signals from pixels of a solid-state image sensor.

Prior Art Conventionally, in order to read pixel data of a solid-state image sensor, two steps are required.
For example, when an oscilloscope is used to measure the output voltage corresponding to each pixel of a CCD, the pixel signal changes so fast that it cannot be followed with the naked eye and the reading accuracy is very poor. Also, a logic analyzer is used to measure quantized pixel data corresponding to pixel density.
It was not possible to determine the temporal variation of pixels, the operation was complicated, and the device was expensive.

Purpose The present invention was made in order to eliminate the drawbacks of conventional pixel data reading. An object of the present invention is to provide an X monitor device that is not influenced by the time/number of pixel data by digitally displaying the average value of pixel data.

A mode that displays all pixels for 47 minutes (Fig. 4 (1)) In addition to the above 7 modes, the mode selection key “°Average °
“Executed by key press”, ili uniformity.

After pressing the key, enter the number of data reads using the numeric keypad, and then select motes 1 to 4 and 6.The CPU 8 reads pixel data for one address the specified number of times, and calculates the average value of the pixel data (1t). There is an 11 average value mode process in which the pixel data of the address is processed (shown in FIG. 4(K)).

The operation when executing each mode will be explained below with reference to FIG.

As shown in FIG. 4(A), when the 1rL source of the embodiment device is turned on, initial processing is executed in step 42, and various flags and registers are initialized. Then, the mode key manual processing in step 44 is performed, and the process waits for the key input from the keyboard 16 to be performed manually.

The mode key manual processing in step 44 is shown in FIG. 4(B). First, in step 46, the mode selection key manual data is read from the key manual register 15, and as shown in step 48, it is checked whether or not a new key manual operation has been performed.If there is no new key manual operation, nothing is done and the mode is set. End key manual processing.

If the mode key was manually input, the process proceeds to step 50 and subsequent steps, and in steps 50 to 64 it is checked which mode key was input. Then, execution mode processing is performed according to each mode key manually.

If it is determined in step 64 that the ``average'' key is manually operated, the process proceeds from step 64 to step 66, where it is checked whether the average flag is set or not. This is to check whether or not i17 average mode processing was performed in the previously executed execution processing mode.If average value mode processing was previously performed and the 11 average value flag was set, teeth·
11 It is considered that the average value mode has been canceled, the average flag is reset, and the mode key manual processing is ended.

If the 11i-equal flag is not set in step 66, in the execution mode I/process to be selected thereafter,
When performing the average value calculation, the number of times the pixel data is read is input using the numeric keypad and the "SET" key is manually pressed, which is monitored in steps 68 and 76.

If you do not want to execute the self-processing, pressing the “Average” key again and inputting F will be considered as cancellation, and step 76
Proceed to YES and cancel =+i average value confidence.

To execute average value processing, the operator inputs the number of times the pixel data is read using the numeric keypad, and then manually presses the SET" key. When the SET" key is input, the process advances to step 70, and the CPU 8 The average number of readings for calculating the average value is manually input, an average flag is set in step 72, and average value processing is performed during subsequent execution mode processing.

When the mode selection key "Mote l" is input in the mode key manual processing, the process proceeds from step 50 to mode l processing in step 51. The details of this mode I processing are shown in Figure 4 (C
).

When the mode selection key "Mode l processing -" is input manually, the process advances to execution mode l processing (step 51), and then step 90 is executed. In step 90, the CPU 8 outputs the decoders 9, 10 . Driver 11
．． The initial state shown in FIG. 5 is displayed on the display devices 18 and 19 via 12.

In this state, the operator uses the ten keys on the keyboard 16 to address the read pixel data of the COD. CPU8
monitors whether or not the ``SET'' key has been input in step 92, and when the ``SET'' key is pressed manually, inputs the manually input pixel data read address in step 94, and performs the average value processing in step 80. Execute.

Details of this average value processing are shown in FIG. 4 (■).

-tz Average value processing first checks in step 190 whether the average flag is set. This is to check whether or not the average value mode processing is specified to execute the average value mode processing in steps 64 to 76 of the mode key manual processing. is set, the processing from step 191 onwards is performed, and when the average value mode processing is not specified, only the reading processing of step 82 is performed. Details of the reading process in step 82 are shown in FIG. 4(J).

In the reading process (step 82), first step 180
In this step, the CPU 8 first outputs the specified pixel data read address from the output port P7 to the address register 5 and decoder 9 as a 4-digit BCD code. The address output to the decoder 9 is decoded by the decoder 9 and automatically displayed on the display 18 via the tryout 11. Does CPU8 have 4 digits in the address register? After outputting the address data, in step 181 output capo)・P
8 outputs an address latch enable signal (LE signal), and sets the output address in the address register. The address data set in this address register is the CCD sent from the image information reading device 25.
a) When the LDE signal 29 synchronized with the response “O°” is input to the load input terminal LD of the counter 6, the counter 6 is preset.
At 82, the output total Hf signal (high level) is output from the output capo P9 to the NAND gate 7, and the reflock signal CLK30 is sent to the clock input terminal C of the counter 6.
It is input to K. This CLK30 is a pixel data transfer lock, and 1 pixel 4. This is a clock that is clocked out for data, and image information is generated in synchronization with this CLK30. The input signal C is manually input to the input buffer 2 via the connector 23. The transferred pixel data is sequentially stored in the holding register 3 at CLK30. When the image data is stored in the holding register 3 and at the same time the NAND gate 7 is satisfied, the counter 6 also receives CL K (1'\), and the address register 5 preset by the LDE signal 29 mentioned above It is counted down in order from f+/i. Then, it is counted down in order, and when the number of CLK signals 30 specified by the address register 5 is manually input to the counter 6, and the pixel data at the specified address position is manually input to the holding register 3. Borrow from counter 6 (digit 41)
A signal BLW31 is output. This BLW Shin + Shinji 11
is an interrupt input (INT) of the CPU 8 and a set signal to the read register 4, and the pixel data at the 7th address position of the CCD specified by the output cap (P7) of the CPU 8 is set to the read register 4, and the CPU 8
This becomes an interrupt request for.

The CPU 8 sets the output capacitor P9 to high level in step 182, and then proceeds to step 183, where the interrupt terminal INT
When the pixel data at the desired address is set in the read register 4, an interrupt request signal is received, so the process proceeds to step 184, and the pixel data in the read register 4 is input from the input port Pl. The pixel data input in step 185 is stored. Then, the reading process ends γ.

If the average flag is set in step 190 of the average value processing (step 80), the process advances to step 191, and step 7 of the mode key manual processing (step 44) is performed.
After reading out the lIi average number set at 0, perform the above-mentioned reading process (step 82), and after reading out the pixel data, proceed to step 193, and check whether the reading process has been executed for the average number of pixels read out in step 191. If the average number of entries has not been read, then the reading process (step 82) is performed an 11-even number of times. and step 1
At step 94, the pixel data obtained by averaging the pixel data read for the average number of units is used as effective pixel data, and the averaging process (step 80) is terminated.

Here, the average number of reads and the read pixel data are temporarily held in a RAM (random access memory) built into the CPU 8 (not shown).

In the execution mode I processing (step 51), when the average value processing at step 80 is completed, the process proceeds to step 96, where the read image data is converted into a 4-digit BCD code. Then the 4-digit B converted in C step 97
The CD code is output from the output port P'6 of the CPU 8 to the decoder IO, where the decoder IO converts it into a display pattern of the 7-segment LED display corresponding to the BCD code, and displays it on the display 19 by try/<12. Thereafter, step 98 waits for one second, checks whether another execution mode is selected in step 44, executes the hold process in step 84, and then returns to the t11 average value process in step 80 to update the read pixel data. , pixel data is read out repeatedly until the next execution mode is selected in mode key manual processing (step 44), and display data is updated.

The hold process in step 84 will now be explained. Details of this hold processing are shown in FIG. 4(L). In the halt process (step 84), first, in step 196, the keyboard 161. Check to see if there is an input for ``Hold Processing''. ``Hold''.

If there is no key, the process returns and the process ends. °°Hold °°CPU8 if there is a jerky mechanism

Drive the 1ζ driver 13 to light up D, and step 19
Wait for the "Hold°" key to be input again in step 7. This is because after pressing the "Hold°" key, the pixel data will not be read or the display data will be updated, and the unused device will be placed in a hold state. By pressing the ``HOLD'' key again, the illumination LED of the ``HOLD'' key is turned off from the output port P5, the halt processing is completed, and the process returns.

The CPU 8 controls the illumination LEDs of the two illuminated keys on the keyboard 16 from the output port P5 in the same manner as described in - every time the mode selection key is pressed.

Furthermore, the display data on the displays 18 and 19 maintains the current display state unless updated.

When the "MOTE 2°" key is pressed to execute execution mode 2, the process proceeds from step 52 of mode key manual processing (step 44) to re-step 53, and executes mode 2 (step 53) processing shown in FIG. 4(D). Execute.

First, in step lOO, the address to be read is set to “0゛′”
After that, perform the Full value processing described in step 8o and 110, read out the pixel data at address O, change the pixel data read in step 102 to a 4-digit BCD code, and send it from the output port P6 of CI) U8. It is output and displayed on the display 19. Then, in step 104, 0.
After waiting for 5 seconds, step 44 mode key manual processing,
Then, the hold process in step 84 is executed. Next, in step 106, the currently displayed pixel data? Check whether the address is the maximum of 7 addresses specified by the 7 address switch 17, and if it is not the maximum of 7 addresses, add 1 to the pixel data read address and repeat the process from step 80 to set the address value σ. Then, when the maximum 7 addresses and the pixel data address being displayed are equal, the process returns to step lOO and the IF primary plI pixel data is displayed again from address O.

The maximum address specified by this address switch 17 is mainly for the solid-state image sensor (CO) in the image information reading device 25.
It is determined by the number of pixels in D).

When execution mode 3 is executed by pressing the ``Mo1ζ3'' key, the mode key manual processing (step 44) proceeds from step 54 to step 55, and mode 3 processing (step 55 and subsequent steps) shown in FIG. 4(E) is performed. Execute.

Further, in step 113, it is checked whether the pixel data has the maximum value, and if it is the maximum value or the minimum value, the maximum value 6ti or the minimum value and its address are stored in step 114 or step 115. In the case of address O, there is no previous read take, so the minimum value is ri/j. Maximum f+ri, /

As explained above, the output signal after A/D conversion of the pixel of the solid-state image sensor (-(CCD)) is sent to the microcomputer 1 (C
By processing using the PU 8), the density levels of the pixels 9 can be digitally displayed with high precision and at high speed.

By selecting and executing execution mode 1, pixel data at the address designated by the CCD is immediately digitally displayed on the display. Therefore, rapidly changing pixel data at the required address can be easily read, sequentially specified, and measured.

By using this, the shading characteristics of the light source in the image reading device can be known, and the light source and pixel data can be corrected based on this shading characteristic.

By selecting and executing one of the execution modes 12, pixel data is displayed in order of address. This mode allows the operator to specify /1111 pixel data without specifying an address. Furthermore, since COD pixel data such as a video signal that changes at high speed is displayed at predetermined time intervals, measurement is easy. Furthermore, the displayed pixel data is displayed in address order, so you can grasp the pixel data covering all 7 trace areas! can.

By selecting and executing execution mode 3, the maximum and minimum values and their addresses are listed in Table 21 among the pixel data for l life in the main scanning direction of the image. This eliminates the need for the operator to sample all pixel data.

Also, the maximum and minimum values are i! II + C by determining
You can know the dynamic range of a CD and use it for image processing.

By selecting and executing execution mode 4,
The second pixel data is displayed. Therefore, if the image reading device is connected to an image processing device such as a printer,
Since the correlation between the original original density, the pixel data value, and the print density can be measured very easily, highly accurate correction can be easily performed by using this as data for correction, etc.

By selecting and executing execution hand 5, the pixel data at the specified address is read a specified number of times, and the maximum difference (1f1) between the pixel data can be displayed. This data allows the CCD pixel data to be read and Variations in A/D conversion can be measured, and the resolution of image density can be determined very easily.

By selecting and executing execution mode 6, the difference between the address designated by the CCD and the adjacent bit can be measured. By measuring this in a certain period of the image reading life, it can be used for reading accuracy of original shading, COD surface surface light illumination point alignment, etc.

By selecting and executing execution mode 7 (low speed mode), pixel signals that are read out at high speed are sampled every several tens to hundreds of pixels (N determined in step 162) and displayed. Changes in the data signal can be reduced to 1/N and displayed. This makes it possible to visually monitor the coolness of the pixel data signal.

In addition, in average value processing, the pixel data is read a specified number of times for a certain address and the value obtained by averaging it' is treated as the pixel data at that address, thereby averaging the pixel data, eliminating the problem of temporal variations in the image collection data. be able to. By eliminating the problem of temporal variations in reading in this way, it is possible to measure changes over time in the light source luminous intensity of the image reading device, the light receiving sensitivity of the CCD, etc.

Also, if you press the "Hold" key while processing each mode, the contents displayed at that point will remain in that state.If you use this mode, the contents will change at regular intervals. It is possible to temporarily stop the displayed content and easily record it.

In addition, in this embodiment, pixel data is taken in by an IC such as the second image of the image reading device board or the back of the data.
It is pin-compatible with the image reader board, so there is no S to stop the flow of data.

It is also possible to return the captured pixel data internally, using a configuration in which one human output connector is used and one pixel is connected to the IC chip on the reader board with a clip. Of course it's a good thing.

It goes without saying that each input/output signal may be connected to an individual clip, which can be easily connected to an IC chip or an IC clip, in the same way as a logic analyzer, etc., instead of a connector. An example in which individual clips are used for sending and receiving human output signals is shown in FIG.

In the figure, 201a to 201e are individual clips.

Effects - As explained, according to the present invention, it is extremely simple. This method averages the pixel data by reading the pixel data a specified number of times for an address, which is a simple operation, and treating the averaged value as the pixel data at that address. By displaying the pixel data digitally, a monitor device that can always read pixel data with high accuracy is realized.

In addition, by eliminating the problem of short-term fluctuations during reading, it is also no longer possible to easily examine changes over time in the light source luminous intensity of the image reading device, the light receiving sensitivity of the COD, etc.

Further, according to the present invention, the pixel data is taken in pin-compatible with an IC such as a pixel data latch on the image reading device board, so there is no way to stop the flow of pixel data on the image reading device board.

It is also possible to return the captured pixel data to a single board, and the number of input/output connectors is reduced to one, which can be connected to the IC chip on the image reading device board with a clip or the like.

In addition, each input/output signal is not connected to a connector, but to an individual clip that can be easily connected to an IC clip, etc. in the same way as a logic analyzer, etc., so there are no restrictions on the exchange of input/output signals. will be realized.
