JP7569508B2 - Image provision system - Google Patents

Description

The present invention relates to an image provision system that provides captured images to a user (person photographed).

Conventionally, image provision systems are known that take ID photographs, etc., to be affixed to resumes, etc., and provide them to users. Such image provision systems photograph people and output prints of photographs of various sizes according to the purpose. In conventional image provision systems, people are photographed by sitting in front of a single background. Therefore, in order to change the background color of the photograph, it is necessary to replace the background.

There is also a known device that uses image processing with chromakey compositing to combine a background image with a portrait image and print it out (see, for example, Patent Document 1). The user can select the desired image from a variety of background images that are prepared in advance.

In chromakey compositing, the person and background in the photographed image are separated and only the person is cut out. The person and background in the photographed image are then combined to generate a composite image. In this case, the background of the photographed image is removed using image processing parameters. If there is unevenness in the background in the photographed image or if the color of the background is similar to the color of the photographed person's clothing, it is not possible to reliably remove the background through image processing, and the original background will remain in the composite image, making it impossible to obtain a clear composite photograph.

Patent No. 4217066

The embodiment of the present disclosure has been made taking these points into consideration, and aims to provide an image providing system that can easily set image processing parameters to appropriate values and reliably remove the background from a captured image, even when there is unevenness in the background or the color of the background is similar to the color of the subject's clothing, thereby producing a clear composite image.

The following describes an embodiment of the present invention with reference to the drawings.

Figure 1A shows a schematic configuration of an image providing system 10 according to this embodiment. Figure 1B shows a captured image and a composite image. The image providing system 10 comprises an image capturing device 2 that captures a subject P and generates a captured image 30 including a background 32 and a person image 31, an arithmetic and control device 1 that performs image processing on the captured image 30, and a printer 5 that prints a print (photograph). This image providing system 10 removes the background 32 from the captured image 30, cuts out the person image 31, and creates a composite image 35 by combining the person image 31 with a background image 33 (see Figures 1A and 1B).

The image providing system 10 does not necessarily have to have the above configuration, and can be configured with at least the arithmetic and control device 1. In this case, the image providing system 10 does not necessarily have to include the imaging device 2 or the printer 5.

The photographing device 2 is, for example, a digital camera, and has a lens, a shutter, a CMOS sensor, an A/D converter, etc. When the photographing device 2 photographs the person P to be photographed, the CMOS sensor receives the photographing light converged by the lens via the shutter, and photoelectrically converts the optical image formed on the light receiving surface, outputting it as an image signal. Then, the A/D converter A/D converts the image signal output from the CMOS sensor to generate photographed image data. The photographed image data generated by the photographing device 2 can be sent to the arithmetic and control device 1 via a medium such as a memory.

The image providing system 10 also has a touch panel 3 that accepts various instructions from a user (person to be photographed) P or store staff S and displays a preview image.

This touch panel 3 has the functions of a display section 3A that displays a captured image 30, a background image 33, and a composite image 35, and an operation section 3B.

Specifically, the touch panel 3 displays operation buttons constituting the operation section 3B, and when an operation button is pressed, it accepts an operation instruction corresponding to that operation button. For example, the touch panel 3 accepts an instruction on the use of the image from the staff S. Note that the user (photographed person) P may operate the touch panel 3 instead of the staff S. The use of the image corresponds to the image size (photo size) that the printer 5 prints on the print material, for example, a driver's license, a passport, a resume, etc. The touch panel 3 also displays at least one candidate background image 33 and can accept an instruction to select the background image 33 from the user P or the staff S. The touch panel 3 can also accept instructions such as color, brightness, pattern, and gradation for the user P to customize the background image 33. The touch panel 3 can also accept an instruction to start printing the printer 5 from the user P or the staff S. The touch panel 3 can also enlarge and display a portion touched by the user when displaying a preview image described later. The display section 3A of the touch panel 3 also displays the photographed image 30 including the background 32 and the person image 31.

The arithmetic and control device 1 is connected to the image capture device 2, touch panel 3, and printer 5, and controls each part and transfers data.

Figure 2 shows the hardware configuration of the arithmetic and control device 1. The arithmetic and control device 1 has a CPU (central processing unit) 11, a main memory 12, a disk device 13, and an input/output unit 14. Each part of the arithmetic and control device 1 is connected via a bus 15.

The disk device 13 stores the image processing program 16 executed by the CPU 11 and the background image to be composited with the person image in a database 17. The database 17 stores multiple background image data with different colors and patterns.

The disk device 13 is, for example, a hard disk drive. Note that the image processing program 16 may be stored in a ROM or a magnetic tape (neither of which are shown) instead of the disk device 13.

The CPU 11 loads the image processing program 16 in the disk device 13 into the main memory 12 and executes the image processing program 16.

As the image processing program 16 is executed, areas are allocated in the main memory 12 for storing captured image data, portrait image data, background image data, composite image data, and corrected composite image data.

Figure 3 is a functional block diagram realized by CPU 11 executing image processing program 16. By executing image processing program 16, a selection unit 21, an image processing unit 22, an image processing parameter setting unit 23, and an image processing parameter correction unit 24 are realized. The selection unit 21, image processing unit 22, image processing parameter setting unit 23, and image processing parameter correction unit 24 form an image processing program execution unit 20 realized by executing image processing program 16.

The selection unit 21 selects and extracts background image data in the database 17 from the disk device 13, and outputs it as background image candidate data to the touch panel 3. Furthermore, when the selection unit 21 receives an instruction to select a background image from the user P or the staff S via the touch panel 3, it passes the background image data selected by the user P to the image processing unit 22.

The image processing unit 22 uses a chromakey compositing process to compose the person image 31 in the photographed image 30 generated by the photographing device 2 with the background image 33 received from the selection unit 21 to create a composite image 35. Specifically, as shown in FIG. 1B, the image processing unit 22 determines the color difference between the person in the photographed image and the background color (wallpaper color), removes the background 32 from the photographed image 30 having the person image 31 and the background 32, and cuts out the person image 31. The color difference determined here is a hue difference, a saturation difference, or a combination of a hue difference and a saturation difference. The image processing unit 22 then superimposes the background image 33 received from the selection unit 21 on the cut-out person image 31 to perform image composition and create a composite image 35. In this case, the image processing unit 22 uses an image processing parameter for removing the background 32 from the photographed image 30 to remove the background 32.

The composite image 35 created in this way is displayed on the display section 3A of the touch panel 3.

As described above, the photographed image 30 includes a background 32 and a person image 31. However, the background 32 of the photographed image 30 may be displayed uniformly overall, or, for example, the lower half may be dark and the upper half may be light. In such cases, when processing using chromakey compositing, unless the image processing parameters are set to optimal values, it is not possible to completely remove the background 32 from the photographed image 30 over its entirety.

In addition, if the background 32 of the captured image 30 and the color of the clothing of the user (subject) P in the person image 31 are similar, for example if both are blue, when processing using chromakey compositing, the background 32 cannot be completely removed from the entire captured image 30 unless the image processing parameters are set to optimal values.

According to this embodiment, as shown in FIG. 3, an image processing parameter setting unit 23 that sets image processing parameters for removing the background from the captured image 30 is connected to the image processing unit 22. In addition, an image processing parameter correction unit 24 that corrects the image processing parameters in the image processing parameter setting unit 23 is connected to this image processing parameter setting unit 23.

The image processing parameters set by the image processing parameter setting unit 23 are then corrected by the image processing parameter correction unit 24 as follows:

That is, when the touch panel 3 changes to an editing screen as described below, the captured image 30 is displayed on the left side of the touch panel 3, and multiple, for example, three sample images 54a, 54b, and 54c that differ in terms of the similarity between the background color and the clothing color are displayed on the right side of the touch panel 3 (see FIG. 7A).

In addition, multiple sample images, for example two sample images 55a and 55b, which differ in terms of background unevenness, are displayed on the touch panel 3 above the sample images 54a, 54b, and 54c.

Furthermore, a key color display section 56 is shown above the sample images 55a and 55b, and an image processing parameter correction display section 57 provided above the key color display section 56 shows specific numerical values of the image processing parameters as the applicable ranges for hue, saturation, and brightness.

In addition, in the editing screen of the touch panel 3 shown in FIG. 7A, among the sample images 54a, 54b, and 54c relating to the similarity between the background color and the clothing color, for example, in sample image 54a, the background color 60 and the clothing color 61 are the same (blue), and among these, the clothing color 61 is a light color (see FIG. 7B).

In addition, in sample image 54b, the background color 60 and clothing color 61 are the same, with clothing color 61 being a darker color.

Furthermore, in sample image 54c, the background color 60 is blue and the clothing color 61 is red, so the hues are completely different.

Of sample images 55a and 55b, sample image 55a has a uniform background color 62 overall (see FIG. 7C). On the other hand, sample image 55b has a background color 63 that includes a light color 63a in the upper half and a dark color 63b in the lower half.

On the editing screen of the touch panel 3, the staff member S looks at the photographed image 30 and selects the sample image 54a, 54b, or 54c that is thought to be the most similar to the photographed image 30, for example, from among the sample images 54a, 54b, or 54c in terms of similarity of background color and clothing color. For example, if the color of the background 32 in the photographed image 30 is blue and the color of the clothing of the person image 31 is red, which are completely different hues, the staff member S selects the sample image 54c.

Staff S also looks at the photographed image 30 and selects the sample image 55a, 55b that is most similar to the photographed image 30, for example, from among the sample images 55a, 55b in terms of background unevenness. For example, if the background 32 in the photographed image 30 is displayed uniformly overall and there is no background unevenness, the sample image 55a is selected.

Sample images 54a, 54b, and 54c relating to the similarity between background color and clothing color correspond to the correction values of image processing parameters, such as the range of application of hue and the range of application of saturation.

For example, when sample image 54c, in which the background color 60 and clothing color 61 are completely different, is pressed and selected from sample images 54a, 54b, and 54c, the correction value of the image processing parameters at that time is determined as the hue application range "10," and the value of the hue application range "10" is displayed on the image processing parameter correction display section 57 of the touch panel 3.

In addition, the background color 60 and clothing color 61 of sample images 54a and 54b are the same, and when either sample image 54a or 54b is selected, the correction value of the image processing parameters at that time is set to the applicable range of saturation, "15," and the value of the applicable range of saturation, "15," is displayed on the image processing parameter correction display section 57 of the touch panel 3.

Furthermore, sample images 55a and 55b relating to background unevenness correspond to the range of correction values for image processing parameters, such as brightness.

When either sample image 55a or 55b is pressed to select it, the image processing parameter correction value at that time is set as the brightness application range "15", and the brightness application range value "15" is displayed on the image processing parameter correction display section 57 of the touch panel 3.

The image processing unit 22 can reduce or enlarge the captured image 30 generated by the photographing device 2 and the created composite image 35 to a size corresponding to the preview display on the display unit 3A of the touch panel 3. The image processing unit 22 can also reduce or enlarge the created composite image 35 to a size corresponding to the photo size to be printed by the printer 5.

When an instruction to start printing is received from the user P or staff S via the touch panel 3, the image data for printing is output from the calculation and control device 1 to the printer 5.

The printer 5 shown in FIG. 1 performs color conversion and sharpness processing on the print image data received from the arithmetic and control device 1. The printer 5 then prints and outputs a composite image 35 of the subject P on paper. The printing method of the printer 5 is not particularly limited, and inkjet method, dye-sublimation thermal transfer method, melting thermal transfer method, etc. can be used.

Next, the operation of the image providing system according to this embodiment will be explained using the flowchart shown in FIG.

First, as shown in Figures 4 and 5A, a user P places an order for a photograph with a store staff member S, and the operation of the image provision system begins. Next, the staff member S photographs the user P using the photographing device 2, and a photographed image 30 is obtained (see Figure 5B).

After that, as shown in FIG. 5C, a preview screen of the captured image 30 appears on the display unit 3A of the touch panel 3, and a composite image 35 is generated from the captured image 30 in the arithmetic and control device 1. This composite image 35 is printed by the printer 5 to produce a printout 5A. User P checks this printout 5A and tells staff S that the generated composite image 35 is the completed image. User P can then access the arithmetic and control device 1 using, for example, a portable terminal P1, and obtain the data of this corrected composite image (see FIG. 5D).

During this time, we will provide a detailed explanation of the operation of the image providing system 10 when generating a composite image from captured images.

The captured image 30 obtained by capturing an image of the user P with the image capturing device 2 includes a person image 31 and a background 32. The data of the captured image 30 is sent to the arithmetic and control device 1 via a medium such as a memory, and the captured image 30 is sent from the arithmetic and control device 1 to the touch panel 3 and displayed on the display unit 30A of the touch panel 3.

In this case, a preview screen of multiple captured images 30 is displayed on the display unit 30A of the touch panel 3 (Figure 6A).

Next, the user P selects a desired captured image 30 from among the multiple captured images 30 on the touch panel 3. In this case, when the user P touches the desired captured image 30, the instruction of the user P becomes an operation by the operation unit 3B of the touch panel 3.

If the user P does not find the desired photographed image 30 among the photographed images 30 on the touch panel 3, he or she can ask the staff member S to take another photograph, take another photograph using the photographing device 2, and repeat the above-mentioned procedure.

Next, user P selects a layout condition 40 in which the captured image 30 should be displayed from among the multiple layout conditions 40 displayed on the touch panel 3 (Figure 6B).

In this case, the user P presses the desired layout condition 40 that constitutes the operation section 3B displayed on the touch panel 3.

Next, as shown in FIG. 6C, the user P touches the editing item 41 constituting the operation section 3B displayed on the touch panel 3 to perform the necessary editing operations on the captured image 30.

Examples of such editing items 41 include editing items for color conversion processing or skin beautification processing performed on captured images.

Next, user P performs chromakey compositing on the captured image. Specifically, background image candidates 43 are displayed on the touch panel 3, and user P selects a desired background image 33 from among the background image candidates 43 (see FIG. 6D).

In this case, the user P touches the desired background image 33 from among the background image candidates 43 on the touch panel 3. This results in an instruction from the user P to select the background image 33 being operated by the operation unit 3B of the touch panel 3.

When the user P touches the touch panel 3 and selects a desired background image by the operation unit 3B, the selection unit 21 of the arithmetic and control device 1 retrieves background image data from the database 17. The image processing unit 22 also uses image processing parameters for removing the background to remove the background 32 from the photographed image 30 including the person image 31 and the background 32 by chromakey compositing, cuts out the person image 31, and synthesizes the person image 31 with the selected background image 33 to create composite image data. In this case, the image processing parameter setting unit 23 has default values of predetermined image processing parameters built in, and the image processing unit 22 uses the default values of the image processing parameters set by the image processing parameter setting unit 23 to remove the background from the photographed image 30. The image processing unit 22 then creates preview image data from this composite image data. Here, the background image used in the composite image is any one of the background images retrieved by the selection unit 21.

Next, the display unit 3A of the touch panel 3 displays a preview screen of the composite image 35 created by the image processing unit 22 (Figure 6D).

If user P accepts the composite image 35 displayed on the touch panel 3, he or she presses the decision button 50 on the touch panel 3.

On the other hand, if the original background 32 remains in the composite image 35 and a clear composite image 35 cannot be obtained, the staff member S presses an edit button (not shown) on the touch panel 3, and the touch panel 3 transitions to an edit screen (Figure 7A).

The reason why the original background 32 remains in the composite image 35 is because the default values of the image processing parameters used in the chromakey compositing process are not appropriate, and therefore the background 32 cannot be properly removed from the captured image 30.

Staff member S operates touch panel 3 to repeat the chromakey compositing process again.

First, as shown in FIG. 7A, the reset button 51 constituting the operation unit 3B on the touch panel 3 is pressed. At this time, the captured image 30 before processing by chromakey compositing appears on the display unit 3A. Also, the image processing parameters set in the image processing parameter setting unit 23 are reset.

The staff member then looks at the photographed image 30 displayed on the display unit 3A and selects a sample image that is similar to the photographed image 30 from among the sample images 54a, 54b, and 54c relating to the similarity between the background color and the clothing color, and the sample images 55a and 55b relating to background unevenness.

For example, if the background color 60 in the captured image 30 is blue and the clothing color 61 is red, and the two are completely different, press sample image 54c. When this sample image 54c is selected, the correction value of the image processing parameter can take a wide range of hue application, and for example, the hue application range is set to "10." In this case, since hue and saturation are in the same category, no correction is made to saturation, and the default value is used as is.

In addition, if the background color 60 and clothing color 61 in the photographed image 30 are the same and the clothing color 61 is dark, a sample image 54b that is similar to the photographed image 30 is selected, and if the background color 60 and clothing color 61 in the photographed image 30 are the same and the clothing color 61 is light, a sample image 54a that is similar to the photographed image 30 is selected.

When sample image 54a or sample image 54b is selected, the correction value of the image processing parameter is determined as the range of application of saturation. In this case, since hue and saturation are in the same category, the default value for hue is used as is without correction.

If there is no background unevenness in the background 32 in the captured image 30, the sample image 55a is selected. At this time, the correction value of the image processing parameter is determined as the applicable range of brightness.

In this embodiment, one sample image is selected from sample images 54a, 54b, and 54c relating to the similarity between the background color and the clothing color, and one sample image is selected from sample images 55a, 55b, and 55c relating to background unevenness.

In this way, the correction values of the image processing parameters can be determined. Based on the correction values of the image processing parameters determined in this way, the image processing parameter correction unit 24 corrects the image processing parameters in the image processing parameter setting unit 23.

The correction values of the image processing parameters set in this manner are displayed on the image processing parameter correction display section 57 provided on the touch panel 3 as the application range of hue, application range of saturation, and application range of brightness.

In addition, on the editing screen of the touch panel 3, the color of a specific point 32a in the background 32 of the photographed image 30 near the person image 31 is defined as a key color, and the correction value of the image processing parameter is found based on this key color. The characteristics of this key color are also displayed in the key color display section 56 on the touch panel 3.

After correcting the image processing parameters in this manner, select the Apply button 52 on the touch panel 3.

As a result, the image processing unit 22 uses the corrected image processing parameters in the same manner as described above to perform chromakey compositing processing to remove the background 32 from the photographed image 30 containing the person image 31 and the background 32, and cut out the person image 31. Next, the person image 31 is composited with the selected background image 333 to create composite image data.

During this time, the touch panel 3 switches from the editing screen (Fig. 7A) to a screen for processing using chromakey compositing (Fig. 6D), and the composite image 35 created by the image processing unit 22 is displayed on the display unit 3A of the touch panel 3. When the user wishes to accept the composite image 35 on the display unit 3A of the touch panel 3, the decision button 50 is pressed.

In the editing screen of the touch panel 3 shown in FIG. 7A, the decision button 50, the reset button 51, the apply button 52, the sample images 54a, 54b, and 54c, and the sample images 55a and 55b all constitute the operation section 3B of the touch panel 3.

Next, when the user accepts the composite image 35 displayed on the touch panel 3 and presses the decision button 50, the composite image 35 is printed by the printer 5 to produce a printout 5A (see Figs. 5C and 8). After that, the user P can check the printout 5A and then access the arithmetic and control device 1 using the mobile terminal P1 to obtain the data of the composite image 35 (see Fig. 5D).

As described above, according to this embodiment, the captured image 30 is compared with the sample images 53a, 53b, 53c, and 54a, 54b on the editing screen of the touch panel 3, and the image processing parameters used when performing the chromakey compositing process in the image processing unit 22 can be easily and simply corrected by simply pressing and selecting the sample images 53a, 53b, 53c, and 54a, 54b that are closest to the captured image.

Therefore, there is no need to input specific conditions or numbers to correct image processing parameters, and not only experienced staff S but also new staff S can easily correct image processing parameters.

In addition, the correction values of the image processing parameters are displayed on the touch panel 3 as the applicable ranges for hue, saturation, and brightness, so that the staff member S who corrects the image parameters can check the correction values of the image processing parameters on the touch panel 3.
