Reference numeral 5 denotes a display device such as a monitor TV, which is used for determining a processing menu and processing parameters, and displaying images before, after, and during processing. Reference numeral 51 denotes a display frame memory inside the display device 5. A coordinate input device 6 such as a digitizer is used to select a processing menu displayed on the display device 5 and to change processing parameters. Reference numeral 7 denotes an output control device, and reference numeral 8 denotes an output device such as a color ink jet printer, which is used to output an image processed by the processing device 3.

Next, the processing of the conventional image processing apparatus will be described below with reference to the flowchart shown in FIG.

First, image information to be a document is set in the image input apparatus 1 (step S101). Next, the image input device 1 is operated to read the image information of the document (step S102). This reading resolution is performed at a resolution required for the output of the last output device 8. Then, the read image information is stored in the storage device 4 via the input control device 2 and the processing device 3 (step S103). Next, parameters required for processing are set using the coordinate input device 6 such as a digitizer (step S104). The setting of this first parameter is
Instead of the operator interactively determining using the coordinate input device 6, a predetermined value may be used.

Next, the processing device 3 reads out the image information stored in the storage device 4 in accordance with the parameters and performs processing, and stores the result in the storage device 4 again (step S10).
Five). Then, the processing device 3 reads the processed image from the storage device 4, reduces it to a size that can be displayed on the display device 5, and transfers it to the display frame memory 51 inside the display device 5 (step S106). When the operator looks at the image on the display device 5 and is not satisfied with the result of this process, the parameter value is changed using the coordinate input device 6 (steps S107 and S108), and the process returns to step S105. Perform the device again with the changed parameter values. On the other hand, if the result of the processing is satisfied, the processed image stored in the storage device 4 is sent to the output control device 7 and the output device 8 to output the processed image (step S109). Thus, all the processes are completed.

[Problems to be Solved by the Invention] By the way, in the conventional image processing apparatus, it is difficult to obtain the result of the transparent synthesis processing desired by the user.

The reason is that it is difficult to set the transmission synthesis parameter that can obtain a desired result.

As described above, in the conventional image processing apparatus, the user cannot easily set the transmission synthesis processing parameters for realizing the desired transmission synthesis processing and the conditions regarding the transmission synthesis processing such as an area to be extracted from each image. Was.

An object of the present invention is to provide a user with an easy-to-use operation environment in the transparent synthesis processing.

[Means for Solving the Problems] In order to achieve the above object, the present invention is an image processing method for performing a transmission synthesis process using a plurality of different images, wherein the plurality of different images are displayed in parallel, An arbitrary region is extracted from each of the plurality of images based on a user's instruction, a region extracted from each of the plurality of images is transparently synthesized, a result of the transparent synthesis is displayed, and an instruction of the transparent synthesis parameter is given. The image processing method is characterized in that a user's instruction value relating to the input is input, and based on the input user's instruction value, the transmission synthesis parameters for each of the plurality of images are set in association with each other.

Further, the adjusted transmission composition parameter is transferred to the image forming apparatus.

Embodiment <First Embodiment> Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

<Description of Apparatus (FIG. 1)> FIG. 1 is a block diagram showing the configuration of the first embodiment according to the present invention. The parts having the same functions as those of the conventional example shown in FIG. 2 are denoted by the same reference numerals, and the description here will be made only for the parts different from the conventional example.

First, reference numeral 31 denotes a processing device A in the present embodiment, which instructs the input control device 2 to read a required image position, and allows the image input device 1 to read a designated coordinate position. In response to this instruction, the image input device 1 reads the image at the designated position, and sends the image information to the processing device A (31) via the input control device 2. Then, the processing device A (31) performs image processing on the received image information according to preset processing contents while utilizing the line buffer 34 provided therein, and outputs the processing result via the output control device 7. To an output device 8 to output an output image.

Next, reference numeral 32 denotes a processing device B in the present embodiment, which indicates a resolution that can be displayed on the display device 5 by the input control device 2, and reads image information of the entire readable area of the image input device 1 from the image input device 1. . Since the resolution of the display device 5 is approximately 640 × 480 pixels in the case of a general monitor TV, the memory capacity may be as small as 0.9 Mbyte (640 × 480 × 3). Therefore, in the present embodiment, the storage device 4 such as a hard disk in the conventional example is not required, and the input image can be stored in the frame memory 33 inside the processing device B (32). The processing device B (32) processes the image stored in the frame memory 33 according to the instruction from the coordinate input device 6, and sends the result to the display device 5. After completing the processing in this way, the processing device B (32) sends a processing instruction and parameters necessary for the processing to the processing device A (31).

The difference between the processing device A (31) and the processing device B (32) in the present embodiment is that the processing device A (31) instructs the input control device 2 to read an image, and While processing proceeds while reading image information, the processing device B (3
In 2), an image is read from the input control device 2 and the image input device 1 in a predetermined format, stored in the frame memory 33, and processing is performed while reading image data from the frame memory 33. Further, the processing device A (31) sends the processed content to the output control device 7 as it is, and outputs it on the output device 8, whereas the processing device B (32)
The processing result is stored in the frame memory 33 again, and the processed image is sent from here to the display device 5 and used for checking processing parameters. As described above, the processing device A (31) for directly accessing the image input / output device 1 to input / process / output a document image and the image once stored in the frame memory 33 are processed and displayed on the display device 5. Processing device B
By having the two processing devices (32), the way of handling the input and output of each data is simplified, and the image processing device can be optimized, so that the processing efficiency is improved.

<Description of Processing (FIG. 4)> Next, the processing of the image processing apparatus in the present embodiment will be described below with reference to the schematic flowchart shown in FIG.

First, in step S1, a document image is set in the image input device 1. Here, FIG. 5 is a perspective view of the image input apparatus 1, and two original images are placed on the original platen 14.
Set 11, 12 with the original side down. Next, in step S2, the entire original image is read in accordance with the instruction of the processing device B (32), and the processing parameters are determined interactively with the operator based on the image information. When the information necessary for the processing is determined in this way, in step S3, this processing information is passed from the processing apparatus B (32) to the processing apparatus A (31). Next, in step S4, the processing device A (31) inputs a document image while accessing the image input device 1 and the output control device 7, and processes the input image information under the designated processing conditions. The processing result is output to the output device 8 via the output control device 7. Then, the image processing is completed by the above processing.

<Description of Combining Process (FIGS. 5 to 12)> Next, in a case where the combining process is performed by transmitting two original images, for example, an image of an underwater image (11 in FIG. 6 described later)
And a background image of the castle (12 in Fig. 6 described later).
An image of Ryugu Castle in the water (see Figure 8 below)
The process of combining 13) will be described below.

FIG. 10 is a detailed flowchart of the processing contents of the processing device B (32) described above.

First, in step S201, the image input device 1 is operated to read the entire readable area (the entire area of the document table 14 in FIG. 5) at a resolution that can be displayed on the display device 5, and in step S202 the input control device 2 is activated. The data is stored in the frame memory 33 inside the processing device B (32). Next, step S203
As shown in FIG. 6, the two original images 11, 12 stored in the frame memory 33 are displayed on the display device 5. In this display method, since the image size stored in the frame memory 33 is the same as the displayable image size, it is only necessary to transfer the data of the two original images in the frame memory 33 to the display device 5. Therefore, the processing can be performed at extremely high speed as compared with the related art in which the image must be reduced every time the image is transferred to the display device 5.

Next, in step S204, a stylus pen 61 of a digitizer (coordinate input device 6) as shown in FIG. 6 is used to cut out a necessary size from the image 11 to be transmitted (underwater image). Is moved, and two diagonal points of the required rectangular area 63 are designated. Next step
In S205, as shown in FIG. 7, a rectangular area 64 having the same size as the rectangle used for the previous clipping is displayed, and is moved to a desired position of the background image 12 (castle image). Thus, the cutout region of the background image 12 can be determined.

When the two rectangular areas are cut out, the combining ratio preset in the processing device B (32) is substituted in step S206, and the transparent combining process is performed in step S207. The processing here is performed on the image 11 to be transmitted.
The value of a certain color (any of R, G, B) of a certain pixel (X1, Y2) is a, the corresponding color value of a pixel (X2, Y2) of the background image 12 is b, and If the set combination ratio is c (where 0 ≦ c ≦ 1), the color value d of the pixel for the image to be processed is calculated by the following equation.

d = a × c + b × (1-c) Note that the relationship between the pixel (X1, Y1) of the image 11 to be transmitted and the pixel (X2, Y2) of the background image 12 with respect to this is calculated by the following equation. Desired. Here, (XD1, YD1) is the upper left point of the original image 11, and (XD3, YD3) is the upper left point of the original image 12.

X2 = XD3 + (X1-XD1) Y2 = YD3 + (Y1-YD1) The amount of calculation performed here is less than half the size of the display screen of the display device 5 (because there are two rectangular areas in the display screen). Therefore, the number of processes is extremely small as compared with the process in the conventional example, and as a result, high-speed processing is possible, and the workability of the operation is extremely improved.

In the processing used here, the image size to be processed is limited to the screen size of the display device 5 or less, and the data access is not performed via an input / output device or a storage device such as a hard disk. No problem. For this reason, the processing apparatus B can use dedicated hardware corresponding to the processing content, or can use a parallel processing processor corresponding to the display pixel size. By using such a dedicated hardware or a parallel processing processor, the processing speed is further increased, and the workability of the interactive operation can be further improved.

When the calculation is performed for all the pixels in the rectangular area at the synthesis ratio of the default value in this way, in step S208, the obtained transmission synthesis pixel 13 is displayed on the display device 5. At this time, at the same time, the operation lever 51, which indicates the composition ratio in FIG.
A scale 52 for determining the output size and an [OK] button 53 for instructing completion of the processing are also displayed. According to this display 13, if the operator is not satisfied with the combination ratio, the user can move the operation lever 51 with the stylus pen (61 in FIG. 6) to select an arbitrary combination ratio (step S20).
9).

Here, if the operation lever 51 is moved,
In S210, a new combination ratio is set, and step S2
The process returns to 07, and the calculation is performed again at the specified combination ratio. By doing so, the operator can interactively determine the level of processing, and workability is greatly improved.

Next, when the composition ratio is determined, it is determined in step S211 whether or not the output image size is to be changed. When the output image size is to be changed, the scale 52 attached below the composite image 13 is changed in step S212. (61 in FIG. 6). FIG. 9 (a) is a diagram showing an initial state of the scale 52. From this state, when one point of the scale 52 is pressed and moved to the right, the scale of the scale is pulled to the right and the unit is drawn. The length increases, and as a result, the size of the rectangular area decreases (FIG. 9B). Conversely, if one point of the scale 52 is pressed and moved to the left, the scale of the scale is compressed and the unit length is shortened, and as a result, the size of the rectangular area is increased (FIG. 9 (c)). ).

In this way, when all the determinations of the composition ratio are completed, the end of the process is determined in step S213, and when the [OK] button 5 is pressed by the operator, the operator performs an operation interactively with the apparatus. Complete. Processing device B
(32) receives the instruction of [OK] and returns to the step shown in FIG.
As shown in S3, information necessary for processing is sent to the processing device A (31). The processing information required for the transparent composition processing is the coordinate values of the two rectangular areas, the composition ratio, and the output size.

Next, the detailed processing contents of the processing apparatus A (31) will be described below with reference to the flowchart shown in FIG.

First, in step S301, the processing device A (31) obtains the reading magnification of the image input device 1 and the reading areas of the two original images 11 and 12 from the parameters received from the processing device B (32).
Here, as shown in FIG.
The rectangular area of (XD1, YD1) to (XD2, YD2) is similarly set. Similarly, the rectangular area of the document image 12 is set to (XD3, YD3) to (XD1, YD3).
D4, YD4). The number of display pixels in the horizontal direction of the display device 5 is LD, the size of the image input device 1 that can be read in the horizontal direction is LR (mm) (shown in FIG. 5), and the output size sent as a parameter is LO. (Mm). In this case, the reading magnification M, the reading area (XR1, YR1) of the image input device 1, (X
(R2, YR2), and (XR3, YR3), (XR4, YR4) are obtained by the following equations.

M = LD × LO ÷ ((XD2-XD1) × LR) XR1 = XD1 × LR ÷ LD YR1 = YD1 × LR ÷ LD XR2 = XD2 × LR ÷ LD YR2 = YD2 × LR ÷ LD XR3 = XD3 × LR ÷ LD YR3 = YD3 × LR ÷ LD XR4 = XD4 × LR ÷ LD YR4 = YD4 × LR ÷ LD Next, before describing the operation of the image input apparatus 1, the main parts of the image input apparatus 1 will be schematically described with reference to FIG. Will be described. Reference numeral 14 denotes a document table shown in FIG. 5, on which documents 11 and 12 are placed. Reference numeral 101 denotes a halogen lamp for illuminating a document.
02, 103, and 104 are reflection mirrors, and 105 is a zoom lens for imaging. These serve to form an image of the document on a line sensor described later. Reference numeral 106 denotes a magnification conversion mechanism including a motor and a gear train for changing the imaging magnification of the imaging lens 105. Reference numeral 112 denotes an RGB color filter, and reference numeral 113 denotes a filter switching mechanism for switching RGB of the color filter 112. The filter switching mechanism 113 is activated, and the filters 112 in front of the line sensor 107 are R, G, B
, The three primary colors are read. 107
Numeral denotes a line sensor such as a CCD and its driving circuit, which reads an original, performs A / D conversion, and sends image information to the input control device 2. 109 is a halogen lamp 101 and a reflection mirror
This is a driving mechanism for sub-scanning 102 in the direction of arrow 110. At this time, the reflecting mirrors 103 and 104 are also moved by arrows 110 by a mechanism (not shown).
The halogen lamp 10 can be moved in the direction
1. The moving distance with respect to the reflection mirror 102 is reduced to half. This mechanism is publicly known, and a detailed description thereof will be omitted. Reference numeral 111 denotes a position detecting device such as a rotary encoder attached to the driving mechanism 109, which is used for detecting an image reading position.

Next, returning to step S302 in FIG. 11, the description will be continued. In step S302, the processing device A (31) sends the reading magnification M obtained by the above formula to the input control device 2, and
The input control device 2 calculates the imaging lens 105 from the reading magnification M.
Of the zoom ring of the image input device 1
To drive the magnification changing mechanism 106. As a result, the imaging lens 105 is set to the designated reading magnification M.

Next, the processing device A (31) starts processing using the image information of the two originals 11, 12. First, in step S303, the input control device 2 is instructed to read a predetermined number of lines of images from the end portions (XR1, YR1) of the image 11 to be transmitted. The input control device 2 controls the end portions (XR1, YR1) of the image 11 transmitted by the position detection device 111 of the image input device 1.
The drive device 109 is moved until the position is detected. When the image reading position reaches the transparent end, an image area of a predetermined number of lines is read from the position at each step S shown in the following equation.

S = M × PI ÷ PO, where PI is the resolution of the input device 1 (dot / mm) PO is the resolution of the output device 8 (dot / mm) Then, the processing device A which has input the image information read in step S304 ( 31) is stored in the line buffer 34 in the processing apparatus A (31) in the next step S305.

Next, in step S306, the area of the background image 12 (XR3, YR
From 3), the input control device 2 is again instructed to read a predetermined line. In response to this instruction, the input control device 2 causes the position detection device 111 of the image input device 1 to change the position (XR
If the image reading position reaches the end of the background image by moving the driving device 109 until the position indicating (3, YR3) is reached, an image area of a predetermined number of lines is read from that position for each step S described above. The result is sent to the processing device A (31) (step S307). Next, in step S308, the processing device A (31) receives the transmitted image information of the background image 12 and the image information of the transmitted image 11 stored in the line buffer 34 from the processing device B (32). Using the ratio of the synthesized
Performs transmission synthesis processing. This processing is performed by the processing device B.
This is exactly the same as the process performed in (32). Then, in step S309, when this processing result is sent to the output control device 7, the result is output to the output device 8 by the output control device 7.

When the calculation of the transmission synthesis and the transfer to the output device have been completed for all the pixels of the image 11 to be transmitted stored in the line buffer 34, it is determined in step S310 whether the processing of all the regions has been completed. For example, the process proceeds to step S311 to instruct the input control device 2 to read image information for several lines next to the image 11 to be transmitted. Then, the process returns to step S304, and the above process is repeated. On the other hand, such processing is repeated in step S310,
If all the areas have been processed, the transmission synthesis processing ends.

As described above, several lines of the image 11 to be transmitted are read and stored in the line buffer 34. Similarly, the corresponding background image 12 is read and subjected to transmission synthesis processing, and the result is output to the output control device 7 / output device. By repeating the transmission to step 8, the transmission synthesis processing can be performed on all the pixels in the designated image area and output.

As described above, in the present embodiment, a processing device A that optimizes line processing for controlling data input from the input device 1 and data output to the output device 8 and performing data processing of a buffer for several lines is created. By doing so, high-speed processing becomes possible.

Further, the processing device B determines the internal processing conditions and the output size based on the pixel size corresponding to the resolution of the display device 5, and the processing device A reads the image again at the pixel size necessary for output based on this information. Since the output is performed while the output is being performed, there is a merit that the capacity of the storage device is extremely small as compared with a method of first reading all the image information and storing it once in the storage device. When all image information is first read, the image must be reduced every time the image information is output to the display device. However, in the method of this embodiment, such processing is not necessary, and the processing speed is increased. . Furthermore, if all image information is read first, it is necessary to recalculate all image information every time the processing parameters are changed, so it takes time to process, and interactive processing is impossible. In contrast, in the method of the present embodiment, only the image having the size necessary to be displayed on the display device needs to be processed, so that the processing time is short and the processing parameters can be changed interactively. In addition, since the output size is determined during processing, there is no need to first read at an appropriate resolution and then thin out or interpolate the image. This eliminates the necessity and makes it possible to perform high-quality processing with little image degradation caused by thinning or interpolation.

In the above-described embodiment, the description has been made with respect to the transmission synthesis processing of two images. However, the present invention is not limited to this processing, and may be used for any image processing such as posterization, mosaic conversion, cutout synthesis processing, etc. be able to.

Further, in the present embodiment, description has been made using an example of a color image, but a similar effect can be obtained by using a monochrome image.

Furthermore, in the present embodiment, the size of the two images combined is the same, but different sizes may be used.

<Second Embodiment> Next, FIG. 13 is a processing flow of the processing device B (32) in a case where original images of different sizes are transparently synthesized. Portions having the same contents as those in the first embodiment described above are assigned the same step S numbers, and therefore only the portions having different processing contents will be described.

After the necessary image area of the image 11 to be transmitted is cut into a rectangle in step S204, a rectangular cursor of the same size appears in the first embodiment, and the background area is cut, but in step S205 in this embodiment. In the background area, the background image is cut out by designating two points on the diagonal of the rectangular area. However, when designating the second point, the position of the point is restricted so that the aspect ratio of the rectangular area matches the aspect ratio of the image to be transmitted. Next, in step S214, the scaling factor M0 of the background image is calculated. This uses a calculation formula of M0 = (XD4−XD3) ÷ (XD2−XD1) (The values from XD1 to XD4 used here are the coordinate values of the rectangular area described in the first embodiment. Shown). Then, in step S207, the background image point (X2, Y1) corresponding to the image point (X1, Y1) to be transmitted using the scaling factor M0 obtained earlier.
The calculation of Y2) is performed as follows.

X2 = INT (XD3 + (X1-XD1) x M0 + 0.5) Y2 = INT (YD3 + (Y1-YD1) x M0 + 0.5) (However, INT is converted to an integer by truncation.) Coordinate value of the background image (X2, Y
The calculation of the transmission synthesis described in the first embodiment is performed using the color value b of 2). Although the nearest neighbor method is used in the calculation formula used here, there are other methods such as a bilinear method and a spline interpolation method, and these methods may be used. Since these methods are well-known techniques, description thereof is omitted here.

Except for the parts described above, the same processing as in the first embodiment is performed, and the processing of the processing device B is completed. Here, the processing apparatus B needs an image scaling function. However, since the image size required for scaling is less than half the image size of the display device, there is no problem in processing speed. Is small, so that image quality deterioration due to zooming is not noticeable. Next, the processing content of the processing apparatus A (31) according to the second embodiment will be described below with reference to the flowchart shown in FIG. The same processing as in the first embodiment is performed as follows.
The same step numbers are assigned, and only the portions having different processing contents will be described.

First, in step S301, different from the first embodiment, the imaging magnification is obtained for both the transmitted image M1 and the background image M2.

M1 = LD × LO ÷ ((XD2−XD1) × LR) M2 = M1 ÷ M0 The zoom lens magnification setting step S302 according to the first embodiment is different from this embodiment.
Instead, a step S312 for setting the magnification M1 before the step S304 for reading the image to be transmitted, and a step S313 for setting the magnification M2 before the step S307 for reading the background image.
Have been added respectively.

The reading of the image to be transmitted in step S304 is performed in step S1 corresponding to the magnification M1, and in step S3.
The reading of the background image of 07 is performed in step S2 corresponding to the magnification M2.
Done in Then, they are obtained by the following equations.

S1 = M1 × PI ÷ PO S2 = M2 × PI ÷ PO Except for the parts described above, the same processing as in the first embodiment is performed, and the processing of the processing device A is completed. As described above, in the processing apparatus A, the image is read while changing the imaging magnification and the reading pitch, so that the processing after reading the image and the magnification processing mechanism become unnecessary, and the image quality is not degraded due to the magnification processing, and the high quality image is eliminated. Output image can be created.

Furthermore, even when the sizes of the two original images are different,
The processing unit B adjusts the image size by the scaling process, while the processing unit A controls the input device to change the magnification of the lens and the reading pitch to adjust the image size. I'm sorry. As a result, the output image is of high quality without image deterioration due to the scaling process. As described above, the two processing devices are optimized by a method in which the respective processes are easily performed, a method in which the processing speed is fast, and a method in which the output image quality is improved. It is superior in processing speed, output image quality, operability, etc. as compared with the device.

[Effects of the Invention] As described above, according to the present invention, a plurality of different images are displayed in parallel, and an arbitrary region is extracted from each of the plurality of images based on a user's instruction, thereby performing the transparent synthesis. It is possible to easily extract an arbitrary region from the image.

Further, according to the present invention, a user can easily set a transmission synthesis parameter and an extraction area from each image, which are required when performing transmission synthesis.

Therefore, according to the present invention, it is possible to provide a user with an easy-to-use operation environment in the transparent synthesis processing.
