Abstract

PROBLEM TO BE SOLVED: To inform a user of a ratio of a valid image region and to prevent wasteful output which a user does not intend in a scanner device in which a size of a display section is not enough.SOLUTION: An image processing condition to input image data is inputted. Image formation region calculating means 24 calculates an area of an image formation region in response to the image processing condition. Valid image region calculating means 25 calculates an area of a valid image region. Since valid image region ratio calculating means 26 calculates a ratio of the area of the valid image region to the area of the image formation region, and displays it on a display section, a user can recognize a size of the valid image formed in a recording medium before an original is read even in a device in which an output image cannot be preview-displayed. Consequently, wasteful output which the user does not intend can be suppressed.

  However, in the conventional image input apparatus and image forming apparatus, if the user makes a mistake in setting, there is a possibility that an unnecessarily white background portion is generated in the output image. For example, when image scaling processing such as enlargement / reduction is performed on a read image after performing frame erasure / center erasure processing, it is difficult for the user to imagine an image of the output image.

  Therefore, in a personal computer or the like, a preview display of the result of performing image processing on the read image is performed on a graphic panel. However, when the image forming apparatus is, for example, an electrophotographic multi-function printer (hereinafter referred to as “MFP”), the display unit is not large enough to display an output image in graphic form. The user cannot recognize the size of the white background until printing on the recording medium. As a result, there has been a problem that a useless output result unintended by the user is obtained.

Based on the input image processing conditions, pre-output image data is generated from the input image data and stored in a predetermined area, and the pre-output image data is an image corresponding to a recording medium size specified by the image processing conditions. Image processing means for moving to the formation area and generating output image data.

  Furthermore, the image input device of the present invention calculates the area of the effective image area by subtracting the area of the predetermined data replacement area from the area of the image forming area and the image forming area calculating means for calculating the area of the image forming area. An effective image area calculating means; an effective image area ratio calculating means for calculating a ratio of the area of the effective image area to an area of the image forming area; and a calculation result output means for displaying the calculated ratio on a display unit. I have.

  The image forming apparatus of the present invention includes the image input device and a printing unit that forms an image on the recording medium based on the output image data generated by the image processing unit.

  According to the image input device and the image forming apparatus of the present invention, image processing conditions are input, and the ratio of the area of the effective screen area to the area of the image forming area is calculated and displayed on the display unit based on the image processing conditions. Therefore, the user can recognize the size of the effective image formed on the recording medium before reading the document even if the apparatus cannot display the preview of the output image. As a result, useless output unintended by the user can be suppressed.

FIG. 5 is a diagram illustrating an output image after the frame erasing process.
In the RAM 20c, pre-output image data is stored in the virtually formed image forming area 40. Specifically, the size of the image forming area 40 is the size of the recording medium, and is, for example, A4 in the first embodiment. The example of FIG. 5 is an example in which an input image of A4 size is input and scaling processing is not performed, and the size of the image forming area 40 and the pre-output image is A4 and coincides with each other.

  In this pre-output image, the frame erasure area 41 is replaced with image data representing white, and output image data is generated leaving the effective image area 42.

That is, the relationship between the image forming area 40, the frame erasing area 41, the effective image area 42, and the pre-output image represented by the pre-output image data in the example of FIG. It is expressed as (3).
Image forming area 40 = effective image area 42 frame erasing area 41 (1)
Output image = (effective image area 42 ∪ frame erasing area 41) ∩ image forming area 40 (2)
Pre-output image = effective image area 42 ∪ frame erasure area 41 (3)

  In the example of FIG. 5, the user specifies the document size as A4, the recording medium size as A4, the width DW of the frame deletion area 41 as 30 mm, and no enlargement / reduction setting as the image processing conditions.

  That is, in FIG. 5, since the image forming area 40 is A4 size, the width PW is 210 mm and the height PH is 297 mm.

In the example of FIG. 6, the user designates the reading size as A4, the recording medium size as A4, the width DW of the frame erasing area 41 as 30 mm, and the magnification as 300% as the image processing conditions.

  That is, in FIG. 6, the image forming area 40 has an A4 size as in FIG. 5, and therefore the width PW of the image forming area 40 is 210 mm and the height PH is 297 mm. Since the width DW2 of the frame erasing area 41 is enlarged by 300%, 30 mm is tripled to 90 mm. The pre-output image exceeds the image forming area 40 because the width and height of the input image whose reading size is A4 are each tripled. By the expressions (2) and (3), the area exceeding the image forming area 40 is removed. As shown in FIG. 6, the image forming area 40 includes a part of the frame erasing area 41 and the effective image area 42. Is stored as output image data.

In the area 34b of the display panel 34, the current effective image area ratio 39.8% is displayed.

(Operation of Example 1)
FIG. 8 is a flowchart showing the operation of the scanner device 10 of FIG. 1 according to the first embodiment of the present invention.

  This process is started when the user starts inputting image processing conditions using the operation panel 30. In this process, an input process of image processing conditions, a process of calculating an effective image area ratio based on the input image processing conditions, and a process of outputting the calculated effective image area ratio will be described. Although not shown, image data input processing, image processing processing, and image output processing are performed in parallel with this processing.

  In step S1, the image processing condition input means 21 inputs the document size A4 from the operation panel 30 to the image forming area calculation means 24 and stores it in the RAM 20c. In step S2, the image processing condition input means 21 inputs the recording medium size A4 from the operation panel 30 to the image forming area calculation means 24 and stores it in the RAM 20c.

  In step S3, the image processing condition input means 21 inputs the width 30 mm of the frame erasure range from the operation panel 30 to the image forming area calculation means 24 and stores it in the RAM 20c. In step S <b> 4, the image processing condition input unit 21 inputs the magnification ratio 300% of the input image data from the operation panel 30 and stores it in the RAM 20 c. Here, when the start button 37 of the operation panel 30 is pressed, the reading unit 11 starts reading a document. The image input unit 22 inputs input image data, and the image processing unit 23 processes the input image data to generate output image data. The process proceeds to step S5.

  In step S5, since the size of the input recording medium is A4, the image forming area calculating unit 24 calculates width PW × height PH to obtain the area of the image forming area 40. Specifically, 210 mm × 297 mm = 62370 square mm.

  In step S <b> 6, the effective image area calculation unit 25 obtains the size of the frame deletion area 41 that is the predetermined data replacement area. When zooming is not specified, the width DW of the frame deletion area 41 is the same as the value of the frame deletion area 41 in the image processing conditions. When the magnification change specification is 300%, the width of the frame deletion area 41 is three times the value of the frame deletion area 41 in the image processing conditions.

In step S7, when there is no zooming designation, the effective image area calculation means 25 calculates the area of the effective image area 42 by the following equation (4).
Effective image area 42 area = (width PW-2 of image forming area 40 × frame erasing width DW)
X (height PH-2 of image forming area 40 x frame erasing width DW) (4)

When the variable magnification designation is 300%, the effective image area calculation unit 25 obtains the area of the effective image area 42 by the following equation (5).
Effective image area 42 area = (width PW of image forming area 40−scaled frame erasing width DW2)
X (height PH of image forming area 40-scaled frame erasing width DW2) (5)

In step S8, the effective image area ratio calculating means 26 obtains an effective image area ratio by the following equation (6).
Effective image area ratio = (area of effective image area 42 / area of image forming area 40) × 100 (6)

  In step S9, the calculation result output means 27 displays the effective image area ratio calculated by the effective image area ratio calculation means 26 on the display panel 34 of the operation panel 30, and ends this processing.

  In the processing of steps S1 to S4, the start button 37 on the operation panel 30 is pressed when the operator determines that the input of the image processing conditions is completed. Therefore, when steps S1 and S2 are completed, when steps S1 to S3 are completed, and when steps S1 to S4 are completed, the start button 37 is pressed.

  Next, a description will be given of (1) when steps S1 and S2 are completed, (2) when steps S1 to S3 are completed, and (3) when steps S1 to S4 are completed.

(1) When Steps S1 and S2 are Completed In this case, the document size and the recording medium size are input, and the width of the frame deletion range and the scaling factor of the input image data are not input. for that reason,
Since the area of the input image = the area of the effective image area 42 = the area of the image forming area 40, the effective image area ratio is 100% from Expression (6).

(2) When Steps S1 to S3 are Completed In this case, the document size, the recording medium size, and the width of the frame erasure range are input, and the scaling factor of the input image data is not input. Therefore, the area of the effective image area 42 is calculated from the equation (4), the area of the effective image area 42 = (width PW-2 of the image forming area 40 × frame erasing width DW)
X (height PH-2 of image forming area 40 x frame erase width DW)
= (210-2 × 30) × (297-2 × 30)
= 35550 square mm
It becomes.

The area of the image forming area 40 is
210 × 297 = 62370 square mm
Therefore, from the equation (6), the effective image area ratio = (the area of the effective image area 42 / the area of the image forming area 40) × 100
= (35550/62370) x 100 = 57.0%
It becomes.

(3) When Steps S1 to S4 are Completed In this case, the document size, the recording medium size, the width of the frame erasing range, and the scaling factor of the input image data are input. Therefore, the area of the effective image area 42 is calculated from the equation (5): area of the effective image area 42 = (width PW of the image forming area 40−scaled frame erasing width DW2)
X (height PH of image forming area 40-scaled frame erasing width DW2) (5)
= (210-30 × 3) × (297-30 × 3) = 24840 square mm
Therefore, from the equation (6), the effective image area ratio = (the area of the effective image area 42 / the area of the image forming area 40) × 100
= (24840/62370) x 100 = 39.8%
It becomes.

(Effect of Example 1)
According to the scanner device 10 and the image forming apparatus of the first embodiment, there are the following effects (a) and (b).

  (A) Before reading the original, the size of the original and the size of the recording medium are input, and the effective image area ratio formed on the recording medium is calculated and displayed. Therefore, the user can recognize the size of the effective image formed on the recording medium before reading the document even if the apparatus cannot display the preview of the output image. As a result, useless output unintended by the user can be suppressed.

  (B) Since the effective image area ratio that changes in accordance with the scaling process of the input image data and the replacement process with the image data representing the white color with respect to the frame deletion area 41 can be calculated, Even if it is difficult for the user to imagine the image of the output image data, it is possible to recognize the size of the effective image formed on the recording medium before reading the document.

(Configuration of Example 2)
FIG. 9 is a functional block diagram illustrating a scanner device 10A according to the second embodiment of the present invention. Elements common to those in FIG. 1 illustrating the first embodiment are denoted by common reference numerals.

  The configuration of the image forming apparatus in the second embodiment is the same as that in the first embodiment. The configuration of the scanner device 10A in the second embodiment is different from that in the first embodiment in that an overall image area calculating unit 51 and an effective image reproduction rate calculating unit 52 are added in the control unit 20A. Other configurations are the same as those of the first embodiment.

  The whole image area calculation means 51 has a function of obtaining the area of the whole image area obtained by removing the frame deletion area 41 from the pre-output image data area. The effective image reproduction rate calculating means 52 has a function of obtaining the ratio of the area of the effective image area 42 to the area of the entire image area.

FIG. 10 is a diagram illustrating an image after the frame erasure process and the enlargement process.
In the example of FIG. 10, the user specifies the document processing size as A4, the size of the recording medium as A4, the width DW of the frame erasing area 41 as 30 mm, and the enlargement ratio as 300%. Yes.

  That is, in FIG. 10, the image forming area 40 has an A4 size as in FIGS. 5 and 6, and thus the width PW of the image forming area 40 is 210 mm and the height PH is 297 mm. Since the width DW2 of the frame erasing area 41 is enlarged by 300%, 30 mm is tripled to 90 mm. The pre-output image 45 exceeds the image forming area 40 because the width and height of the input image data whose read size is A4 are each tripled.

  A portion obtained by removing the frame deletion area 41 from the pre-output image 45 is an entire image area 44 to be displayed. By the expressions (2) and (3), the area exceeding the image forming area 40 is removed, and as shown in FIG. 10, a part of the image in the frame erasing area 41 and the effective image are included in the image forming area 40. A part of the image in the region 42 is stored as output image data in the RAM 20c in FIG. Of the entire image area 44, the part excluding the effective image area 42 is an invalid image area 43, which is a part that is not output to the recording medium.

  FIG. 11 is a diagram showing a display example of the effective image area rate and the image reproduction rate on the display panel 34 in FIG.

  In the area 34a of the display panel 34, the reading size A4, the enlargement / reduction 300%, the output paper A4, the frame deletion 30 mm, and the like, which are the current image processing conditions, are displayed. In the area 34b of the display panel 34, the current effective image area ratio 39.8% and the image reproduction ratio 23.2 are displayed.

  FIG. 12 is a flowchart showing the operation of the scanner device 10A in FIG. 9 according to the second embodiment of the present invention.

  This process is started when the user starts inputting image processing conditions using the operation panel 30.

  The same steps S1 to S8 as in the first embodiment are executed, and the effective screen area ratio is calculated.

In step S21 different from the first embodiment, the area of the entire image area 44 is calculated by the following expression (7) by the entire image area calculating unit 51.
Total image area 44 area = (input image width−2 × frame erase area 41 width)
X (height of input image-2 x width of frame erasing area 41) x scaling factor (7)

In step S22, which is different from the first embodiment, the effective image reproduction rate calculating unit 52 calculates the effective image reproduction rate according to the following equation (8).
Effective image reproduction rate = (area of effective image area 42) / area of entire image area 44) × 100 (8)

  In step S9 similar to the first embodiment, the calculation result output means 27 operates the effective image area ratio calculated by the effective image area ratio calculation means 26 and the effective image reproduction ratio calculated by the effective image reproduction ratio calculation means 52. The information is displayed on the display panel 34 of the panel 30, and this process is terminated.

  As in the first embodiment, in the processes in steps S1 to S4, the start button 37 on the operation panel 30 is pressed when the operator determines that the input of the image processing conditions has been completed. Therefore, when steps S1 and S2 are completed, when steps S1 to S3 are completed, and when steps S1 to S4 are completed, the start button 37 is pressed.

  Next, (a) when the steps S1 and S2 are completed, (b) when the steps S1 to S3 are completed, and (c) when the steps S1 to S4 are completed will be described.

(A) When steps S1 and S2 are completed In this case,
Since the area of the input image = the effective image area 42 = the area of the entire image area 44, the effective image recall is 100% from the equation (8).

(B) When Steps S1 to S3 are Completed In this case, the area of the effective image area 42 is calculated from the equation (4) as follows: The area of the effective image area 42 = (width PW-2 of image forming area 40 × frame erasing width DW) )
X (height PH-2 of image forming area 40 x frame erase width DW)
= (210-2 × 30) × (297-2 × 30)
= 35550 square mm
It becomes.

The area of the entire image area 44 is calculated from the equation (7) as follows: (210-2 × 30) × (297-2 × 30) = 35550 square mm
Therefore, from equation (8), effective image reproduction rate = (area of effective image area 42 / area of entire image area 44) × 100
= (35550/35550) x 100 = 100%
It becomes.

(C) At the time when Steps S1 to S4 are completed In this case, the area of the effective image area 42 is calculated from the equation (5): area of the effective image area 42 = (width PW of the image forming area 40−scaled frame erasure) Width DW2)
X (height PH of image forming area 40-scaled frame erasing width DW2) (5)
= (210-30 × 3) × (297-30 × 3) = 24840 square mm
It becomes.

The area of the entire image area 44 is calculated from the equation (7).
X (the height of the input image-2 x the width of the frame deletion area 41) x scaling factor = (210-2 x 30) x (297-2 x 30) x 3
= 106650 square mm
Accordingly, the effective image reproduction rate is calculated from the equation (8). Effective image reproduction rate = (area of the effective image region 42) / area of the entire image region 44) × 100 (8)
= (24840/106650) x 100 = 23.2%
become.

(Effect of Example 2)
According to the scanner device 10A and the image forming apparatus of the second embodiment, in addition to the effects of the first embodiment, the effective image reproduction rate is calculated and displayed. Therefore, the reproduction rate of the image that should originally be formed on the recording medium. Can be grasped. Therefore, useless output unintended by the user can be more effectively suppressed.
