0a and only the image data stored in one of the second line buffers 50b (that is, only every other pixel data) is stored in the first frame memory unit 51, so that the pixel data in each line is stored. The number is further reduced to 1/2. As a result, finally, the number of pixel data of the image data obtained by the prefetch is 1/16.

In addition, the START / ENTER key has the same function as the return key or the execute key on a normal keyboard, so you can confirm the value set with the numeric keypad, etc.
It has the function of executing specified instructions. It also has a function as an image reproduction start key for starting reproduction of a color image based on the set conditions. A color image reproducing system including the transmissive image reading device 10 or the reflective image reading device 30, the image processing device 5 and the image output device 8 configured as described above is configured as follows in the following manner. The color image recorded on is read to generate image data, the image data is subjected to image processing, and the color image is reproduced on the color paper 90.

When a color image recorded on a film F such as a negative film or a reversal film is reproduced, the operator uses the keyboard 69 to perform a CR operation.
The input device operation screen (not shown) of T68 is called, and the transparent image reading device 10 is selected on this screen. By this selection operation, the transmissive image reading device 10 is connected to the interface 48 of the image processing device 5 via the interface 21, and when the user sets the film F on the carrier 22, a drive signal is output from the CPU 60. It is output to the motor 23, and the motor 23 drives the drive roller 24. As a result, the film F is conveyed in the direction of the arrow. The screen detection sensor 25 detects the density distribution of the film F and outputs the detected density signal to the CPU 26. Based on this density signal, the CPU 26 calculates the screen position of the color image recorded on the film F, and when it determines that the screen position of the color image has reached a predetermined position, stops driving the motor 23. As a result, the color image recorded on the film F is stopped at the predetermined screen position with respect to the CCD area sensor 15 and the lens 16. Light is emitted from the light source 11 at a predetermined timing,
The light amount is adjusted by the light amount adjusting unit 12.

In this embodiment, the color image recorded on one frame of the film is read twice,
The image reading condition is determined based on the first image data obtained by the first reading (pre-reading), and the light amount adjusting unit 12 determines the light amount of the light with which the film F is irradiated and the accumulation time of the CCD area sensor 15. The reading is adjusted and the second reading (main reading) is performed. Therefore, at the time of pre-reading, the light source 11
The light emitted from the light source is adjusted to a predetermined light amount by the light amount adjustment unit 12, and is converted to R by the color separation unit 13.
(Red), G (green), and B (blue) are separated into three colors. First, R (red) light is applied to the film F, and then G (green) light is finally irradiated. The B (blue) light is applied to the film F, respectively, and the light transmitted through the film F is photoelectrically read by the CCD area sensor 15. In this pre-reading, the CCD area sensor 15
The CPU 26 controls so that only the image data corresponding to the color image of either the odd field or the even field is transferred to the amplifier 17.
The number of lines of image data corresponding to the odd field or the even field is 1/2 of the number of lines of the read color image, and therefore the number of pixel data thereof is 1/2.

The image data for one field generated by reading the color image by the CCD area sensor 15 is amplified by the amplifier 17, and then converted into a digital signal by the A / D converter 18. The image data converted into a digital signal is subjected to correction of variations in sensitivity and dark current for each pixel by the CCD correction means 19, and after being converted to density data by the log converter 20, the interface 21 and the interface. 48
Only the image data of the odd field or the even field is sent to the image processing device 5 line by line via the. On the other hand, when reproducing the color image recorded on the color print P, the operator calls the input device operation screen on the CRT 68 using the keyboard 69, and the reflection type image reading device 30 is displayed on this screen. select.
By this selection operation, the reflective image reading device 30
Is connected to the interface 48 of the image processing apparatus 5 via the interface 41, and the color print P is supported by the carrier 42. The light emitted from the light source 31 is reflected by the surface of the color print P, passes through the mirror 32, and enters the color balance filter 33,
After the R, G, and B sensitivities have been adjusted, the light amount adjustment unit 3
The light quantity is adjusted by 4. As described above, in the pre-reading, the light emitted from the light source 31 is adjusted to a predetermined light amount by the light amount adjustment unit 34, and R,
C consisting of 3 line sensors corresponding to G and B respectively
The CD line sensor 35 receives the light and photoelectrically reads it. Here, the light source 31 and the mirror 32 are moved at a predetermined speed in a direction indicated by an arrow in FIG. 3, that is, in the sub-scanning direction by a driving unit (not shown), and as a result, the carrier (FIG. The color image recorded on the color print P supported by (not shown) is two-dimensionally read, and the image data corresponding to R, G, and B is converted into CC.
Generated by the D line sensor 35. At the time of pre-reading, the moving speed of the light source 31 and the mirror 32, that is, the sub-scanning speed is set to be twice as high as that at the time of main reading.

The image data corresponding to R, G and B generated by the CCD line sensor 35 is amplified by an amplifier 37 and then converted into a digital signal by an A / D converter 38. The image data converted into a digital signal is processed by the CCD correction means 39.
After the variation of the sensitivity for each pixel and the correction of the dark current, the log converter 40 converts the density data into density data, and then, via the interface 41 and the interface 48,
Each line is sent to the image processing device 5. When the image processing device 5 receives the image data from the transmissive image reading device 10 or the reflective image reading device 30, the arithmetic mean unit 49 causes the averaging calculation means 49 to display two adjacent pixels of the image data sent line by line. By adding the data values, averaging them, and allocating them to one pixel data, the number of pixel data of each line of the image data is reduced to 1/2. Next, the CPU 60 outputs only the pixel data of one of the odd line and the even line of the image data to the first line buffer 50a and the second line buffer 50.
b, alternately, that is, the odd-numbered pixel data of each line is supplied to one of the first line buffer 50a and the second line buffer 50b, and the even-numbered pixel data of each line is supplied to the first line buffer 50a. 50a and the second line buffer 50b are respectively stored.
Therefore, of the image data output from the arithmetic mean calculation processing means 49, only the image data of one of the odd line and the even line is transferred to the first line buffer 50a and the second line buffer 50b. 1
Line buffer 50a and second line buffer 5
The number of lines of the image data stored in 0b becomes 1/2.

At the time of pre-reading, the CPU 60
Connects one of the first line buffer 50a and the second line buffer 50b and the first frame memory unit 51 to the input bus 63, and connects the second frame memory unit 52 and the third frame memory. The unit 53 and the input bus 63 are controlled to be disconnected so that only the image data stored in the one line buffer 50a or 50b, that is, the odd-numbered pixel data of one of the odd line and the even line Alternatively, only the even-numbered pixel data is sequentially transferred to the first frame memory unit 51 as the pre-read image data. As a result, the number of pixel data in each line of image data is reduced to 1/2. In this way, the image data corresponding to the color image recorded on the film F of one frame or the color print P of one sheet is finally reduced to 1/16 in the number of pixel data to correspond to R, G and B. The image data to be reproduced are the R data memory 51R and the G data memory 51G of the first frame memory unit 51, respectively.
And B data memory 51B. Thus,
The image data read by the prefetch and stored in the first frame memory unit 51 is sent to the data bus 65 and analyzed by the CPU 60. The CPU 60
Based on the image data read by the pre-reading, the reading control signal is transmitted through the data bus 65 so that the color image is read by the main reading so as to be suitable for the dynamic range of the CCD area sensor 15. The image is output to the CPU 26 of the apparatus 10 or the CPU 46 of the reflection type image reading apparatus 30, and an image having optimum density, gradation and color tone can be reproduced on the color paper 90 based on the image data obtained by the main reading. First, the image reading conditions for the main reading are automatically determined.

CPU 26 of transmissive image reading device 10
Alternatively, the CPU 46 of the reflection-type image reading device 30 is C
Based on the reading control signal input from the PU 60, the film F is irradiated with a desired amount of light at the time of actual reading, or the desired amount of light reflected by the color print P is reflected by the CCD line sensor 35. The light amount adjusting unit 12 or the light amount adjusting unit 33 is controlled so that the light is received, and the accumulation time of the CCD area sensor 15 and the CCD line sensor 15 is adjusted. At the same time, the CPU 60, if necessary, according to the analysis result of the image data read by the prefetch,
A control signal is sent to the first image processing means 61 and the second image processing means 62 via the data bus 65, and image processing conditions such as image processing parameters are corrected. Further, the image data read by pre-reading and stored in the first frame memory unit 51 is sent to the second image processing means 62, and gradation correction, color conversion, density conversion, etc. are performed by a look-up table or matrix operation. After the image processing of CRT 68 is performed through the data bus 65,
And a color image is displayed on the screen of the CRT 74.

The operator observes the color image displayed on the screen of the CRT 68 and, if necessary, operates the keyboard 69 to appropriately correct the image reading condition and / or the image processing condition for the main reading. can do. When the operator operates the keyboard 69 and inputs an instruction signal that the image reading condition and / or the image processing condition for the main reading should be corrected, the instruction signal is sent to the CPU 60 via the data bus 65. Is entered. The CPU 60 generates a control signal based on the instruction signal and outputs the control signal to the data bus 65, and the control signal is the CPU 26 of the transmissive image reading apparatus 10 or the CPU 46 of the reflective image reading apparatus 30 and / or the first image. Processing means 60 and / or second image processing means 6
1 to modify the image reading condition and / or the image processing condition. In the present embodiment, the data bus 65 is formed separately from the input bus 63 and the output bus 64 of the first frame memory unit 51, the second frame memory unit 52, and the third frame memory unit 53. Therefore, the image data is stored in the first frame memory unit 51 and the second frame memory unit 52.
Alternatively, while inputting to the third frame memory unit 53 or outputting image data from these, the operator can input various instruction signals, and on the screen of the CRT 68, A color image can be reproduced.

In the keyboard 69 according to this embodiment, the "F1" key is used for image rotation, the "F5" key is for gradation curve selection, the "F6" key is for saturation selection, and the "F7" key is for sharpness selection. "-5", "-C", "-M", "-"

The key is a color tone and density correction key, that is, the operator adjusts the color tone and density of the reproduced color image while observing the color image displayed on the CRT 68 based on the image data obtained by the pre-reading. These keys are used, and the operator selectively operates these keys to reproduce the color image having the desired color tone and density, and the first image processing means 61.
It is possible to set the condition of the image processing executed by. Further, the operator can operate the print size key and the peaset key on the keyboard 69 to set the size of the reproduced color image and the number of prints.

In this way, when the image reading condition and / or the image processing condition for the main reading are determined by the pre-reading or the instruction of the operator, the main reading for reproducing the color image is started. At the time of actual reading, the CCD line sensor 15 of the transmissive image reading device 10
Generates image data of an odd field and an even field of a color image recorded on one frame of the film F. Further, the CCD line sensor 35 of the reflection image reading device 30 operates at a low sub-scanning speed to produce one color image. The color image recorded on the print P is read to generate image data, and the image data is input to the image processing apparatus 5 line by line via the interface 21 or the interface 41 and the interface 48. The image data read by the main reading input to the image processing device 5 is input to the averaging arithmetic operation unit 49, but during the main reading, the addition processing operation unit 49 does not perform addition processing on the image data, All the input image data is transferred line by line to the first line buffer 50a and the second line buffer 50b, and the first line buffer 50a and the second line buffer 50b are transferred.
, And store them alternately. At this time, the CPU 60 sends the odd-numbered pixel data of each line of the image data to one of the first line buffer 50a and the second line buffer 50b and the even-numbered pixel data of the first line buffer 50a and the first line buffer 50a. On the other side of the second line buffer 50b,
Each is controlled so as to be stored.

At the time of actual reading, the CPU 60 causes the
Of the second frame memory unit 52 and the third frame memory unit 53, only the frame memory unit capable of writing image data is connected to the input bus 63, and the other frame memory unit and the first frame memory unit 51. Is controlled so that the connection between the input bus 63 and the input bus 63 is cut off. That is, when a color image is read, only one of the first frame memory unit 51, the second frame memory unit 52, and the third frame memory unit 53 is connected to the input bus 63. The image data is stored only in the frame memory unit. This is the image data corresponding to the color image recorded on the frame with the film F or the color image recorded on one color print P obtained by the actual reading through the output bus 64 and the selector 55. While being transferred to the first image processing means 61, it is possible to execute the pre-reading of the color image recorded on the next frame of the film F or the color image recorded on another color print P, and further by the main reading. Image data corresponding to the obtained color image recorded on a frame of the film F or the color image recorded on one color print P is output to the first image processing means via the output bus 64 and the selector 55. During the transfer to 61, the color image recorded on the next frame of the film F or the color image recorded on another color print P is transferred. Data reading efficiency of the color image reproducing system can be achieved by completing the reading and executing the main reading of the color image recorded on the next frame of the film F or the color image recorded on another color print P. Is to improve. Therefore,
Alternately, the image data stored in the first line buffer 50a and the second line buffer 50b is transferred to the second frame memory unit 52 or the third frame memory unit 53 and corresponds to R (red). Image data is stored in the R data memory 52R or 53R in G (green)
The image data corresponding to is the G data memory 52G or 5
The image data corresponding to 3R and B (blue) are stored in the B data memory 52B or 53B, respectively, and are stored in the second frame memory unit 52 or the third frame memory unit 53, and the film F or 1 of one frame is stored. Image data corresponding to the color image recorded on the one color print P is stored.

The image data obtained by the main reading is the R data memory 52R or 53 of the second frame memory unit 52 or the third frame memory unit 53.
After being stored in the R, G data memory 52G or 53R, B data memory 52B or 53B, the image data is
It is output to the first image processing means 61. Here, C is set so that only the image data stored in either the second frame memory unit 52 or the third frame memory unit 53 is output to the first image processing means 61.
The PU 60 controls the selector 55. First
In the image processing means 61, the color density gradation converting means 1
00 converts the density data, color data, and gradation data of the image data according to the look-up table, and the saturation conversion unit 101 converts the saturation data of the image data according to a matrix operation.
Then, according to the size of the color image to be output on the color paper 90, the digital magnification conversion means 102
After the number of pixel data of the image data is increased or decreased, the frequency processing means 103 performs frequency processing such as sharpness enhancement on the image data, and the dynamic range conversion means 104 converts the dynamic range to obtain the data. It is output to the synthesizing means 75.

The operator uses the keyboard 69 to
When an instruction signal indicating that the data should be combined with the image data obtained by reading the color image is input, the CPU 6
The data combining signal is output from 0 to the data combining unit 75, and the data combining unit 75 reads the image data such as a figure or character to be combined with the image data obtained by reading the color image from the combined data memory 76. Synthesize
On the other hand, when no instruction signal is input to the keyboard 69, no processing is executed. After that, the image data is
It is output from the data synthesizing means 75 to the image output device 8. The instruction to combine the image data with the color image is
It is performed in a predetermined dialog opened by operating the menu key, the up and down arrow keys, and the left and right arrow keys.
Furthermore, when synthesizing graphic data, what graphic is to be composited to where in the color image in the dialog opened by selecting "Index print" which is a submenu of the "Input device operation (3)" menu. Or set. Also, when synthesizing character data, the font, size, and output position of the character to be synthesized are displayed in the dialog 7 that is opened by selecting "Front Print", which is a submenu of the "Input device operation (3)" menu. Etc. are set.

From the data synthesizing means 75 of the image processing apparatus 5, an interface 77 and an interface 78 are provided.
When the image data is input to the image output device 8 via the, the input image data is stored in the image data memory 80 including a plurality of frame memories. Since the reading operation of the color image recorded on the film F or the color print P and the operation of the image output device 8 are not synchronized with each other, they are read by the image reading device 1.
The image data subjected to the image processing by the image processing device 5 is input to the image output device 8 regardless of the processing of the image output device 8. Therefore, in the present embodiment, the image data memory 80 that stores the image data input from the image processing device 5 is configured by a plurality of frame memories, and the image data is sequentially stored in the frame memory. Even if the image reading device 1 reads an image at high speed and the image data is sent to the image output device 8, the image output device 8 reproduces the color image on the color paper 90 at a predetermined speed. I guarantee that you can. Each means in the image output device 8 is a CPU

Modulation signals are input to the optical modulators 87R, 87G, and 87B from the modulator driving means 83, and their intensities are modulated according to the modulation signals, that is, image data,
The laser light is reflected by the reflection mirrors 88R, 88G, 88B and enters the polygon mirror 89. The polygon mirror 89 is rotated at a predetermined speed, and the laser light is reflected by the polygon mirror 89 on the surface of the color paper 90 being conveyed in the sub scanning direction by the fθ lens 9.
The main scanning is performed via 3. Therefore, the color paper 70 is two-dimensionally exposed by the R, G, and B laser beams. Since the color paper 90 is conveyed in the sub-scanning direction in synchronization with the rotation of the polygon mirror 89, the color paper 90 corresponds to the color image recorded on the film F or the color print P.
Will be exposed by the laser light.
