Abstract

PROBLEM TO BE SOLVED: To enable a user to quickly look at an image subjected to desired conversion when converting an image into a painting tone image.SOLUTION: Thumbnails 1 to 16 being reduced images of a stored original image are displayed (step S101). When an optional thumbnail is touched in this state, the thumbnail is subjected to picture tone conversion into an image of predetermined picture tone (e.g., oil painting tone) (steps S109 and S111). When the thumbnail subjected to picture tone conversion is further touched again, the thumbnail is converted into an image of different picture tone (e.g., watercolor picture tone) (repetition of steps S109 and S111). When a collective conversion button is touched, all of the displayed thumbnails are collectively converted into images of predetermined picture tone (step S104), and when a thumbnail subjected to some picture tone conversion is doubly touched, the double touch is regarded as conversion determination, the original image is subjected to picture tone conversion and the converted image is displayed over the entire screen (step S116).

Description

  The present invention relates to an image display device, an image tone conversion service system, a terminal, a server, and an image display method, and more particularly to a technique for converting an image into an image having a different image tone.

  In recent years, with the widespread use of digital cameras, it has become common to store photographs as digital image data. In the case of shooting with a conventional film camera, it was often accompanied by printing, but in the case of image data, it can be browsed with a digital camera that has shot, or it can be browsed with a personal computer that captures image data, etc. There are also changes in the way photos are enjoyed.

  In such a situation, so-called digital photo frames are realized and popularized so that image data can be enjoyed in the same way as a conventional print photograph (for example, Patent Document 1).

  Digital photo frames can realize various display modes such as displaying multiple photos in a slideshow format that could not be done with photo frames that display conventional print photos by taking advantage of the characteristics of digital methods, and image processing For example, an invention has been proposed in which an image having a different tone (for example, a painting tone) can be generated and displayed based on an original photograph (for example, a patent) Reference 2).

  As a result, it can be enjoyed as if it were a picture, not just a photograph. However, in the technique described in Patent Document 2, in order to simulate in units of pixels, the artistry is enhanced in consideration of the entire image. There was also a shortage.

  Therefore, by extracting features such as color information and handwriting information from the picture of the picture actually drawn by the painter, and adding the extracted features to the photographed image, it is highly artistic considering the entire original image A technique for converting to a picture-like image has also been proposed (for example, Patent Document 3).

  Thus, as image processing for obtaining an image with high artistry from the original image, it is possible to realize image processing for generating image data that further enhances the artistic effect by taking the entire original image into consideration.

(First embodiment)
Hereinafter, embodiments of the present invention will be described. 1A is a front view of a digital photo frame (hereinafter referred to as DPF) 1 to which the present invention is applied, and FIG. 1B is a side view of the DPF 1. The front surface of the DPF 1 is almost entirely occupied by a display unit configured by the liquid crystal display panel 3 held by the main body 2. A human sensor 14 is disposed on the upper front of the main body 2, and a power switch 4, an operation switch 5, and a memory card slot 6 are provided on a side surface.

  FIG. 2 is a block diagram showing the electrical configuration of the DPF 1. The DPF 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12 connected to the CPU 11, a RAM (Random Access memory) 13, the human sensor 14, a power switch 4 and an operation switch 5. Unit 15, display controller 16, memory card controller 17, touch panel 19, and wireless communication unit 20.

  The ROM 12 stores a program for causing the CPU 11 to perform an operation shown in a flowchart described later. The ROM 12 stores a program for tone conversion. For example, an oil painting, a watercolor painting, a pastel painting, a pencil drawing, a crayon drawing, an illustration drawing, a point drawing, an airbrush drawing actually drawn by a painter. Japanese Patent Application Laid-Open No. 2004-213598 which extracts each original image and features such as color information and brush stroke information from these original images, and performs a tone conversion process on the input image by adding the extracted features to create a converted image tone image Also stored is a converted image-tone image creation program based on the technology disclosed in the above.

  The RAM 13 is a working memory in which the CPU 11 temporarily stores various data as necessary. The human sensor 14 is for detecting whether or not the person who is viewing the image of the DPF 1 is in the vicinity. The human sensor 14 includes a sensor using a pyroelectric element that detects infrared rays emitted from a human body, a sensor using ultrasonic waves, and the like. Become. An image sensor may be provided. If the image sensor is used, image recognition is possible, and more complicated control can be realized.

  The display controller 16 causes the liquid crystal display panel 3 to display an image represented by the image data by driving the liquid crystal display panel 3 based on the display image data supplied from the CPU 11. The memory card controller 17 is an input / output interface that controls input / output of data between various memory cards 18 detachably mounted in the memory card slot 6 and the CPU 11 connected thereto. The touch panel 19 is stacked on the liquid crystal display panel 3 and detects the touch position of the user's finger on the liquid crystal display panel 3. There are various touch input methods such as an optical method and a capacitance method, and the touch input method is not limited to the method, and the position detection may be selected by a cursor.

  The wireless communication unit 20 is connected to the antenna 21 and performs communication processing including terminal authentication processing. The wireless communication unit 20 performs WWW connection control, includes a packet data generation circuit and a packet data restoration circuit, and performs data processing according to a communication protocol.

  The DPF 1 is provided with a normal mode and an effect mode as operation modes, and the operation mode can be switched by the user operating the operation switch 5 in a predetermined procedure.

  The normal mode is an operation mode in which an image stored as image data in the memory card 18 is displayed as it is on the liquid crystal display panel 3 as in a general DPF. An image that can be displayed in the DPF 1 is an image captured by a digital camera, for example, and is an image that is compressed by a JPEG (Joint Photographic Expert Group) method and stored as a still image file together with additional information such as the shooting date and time. is there. Of course, various image formats such as RAW, BMP, and PNG can be supported. The image source does not have to be taken with a digital camera.

  In the effect mode, the image to be displayed stored in the memory card 18 is converted into a painting-like image having characteristics of the painting, that is, a painting-like image having a specific effect, and the converted painting-like image is converted into a painting-like image. This is an operation mode displayed on the liquid crystal display panel 3.

  Further, in the effect mode, it is possible to select a target painting type, that is, a characteristic (image tone) that can be converted into a converted image, when converting to a painting image. In the present embodiment, selectable image styles are oil painting style, watercolor painting style, pastel painting style, pencil painting style, crayon painting style, illustration painting style, point drawing style, and airbrush painting style. However, the present invention is not limited to this, and it is possible to select conversions that take into account the characteristics of the painter, such as Van Gogh, Monet, and Picasso. Further, another image tone algorithm can be provided by a memory card 18 described later.

  In the present embodiment, a program for converting into eight types of painting tone from oil painting to airbrush painting is stored, but the priority order is (1) oil painting, (2) watercolor painting, (3) Pastel stroke, (4) Pencil stroke, (5) Crayon stroke, (6) Illustration stroke, (7) Point drawing stroke, and (8) Airbrush stroke.

  FIG. 3 is a memory configuration diagram showing the recorded contents of the memory card 18. This memory card 18 is detachably attached to the digital camera, and the images are filed in the JPEG file format with the digital camera and a plurality of F1, F2, F3,. -(16 sheets or more in the present embodiment) are recorded. Each file F1, F2, F3,... Includes a header having data such as EXIF (Exchangeable Image File Format), and image data (main images 1, 2, 3,. ) And thumbnail image data (thumbnail 1, 2, 3,...) That is a reduced image of the image data. Since the size of the reduced image to be displayed on the screen differs depending on the size of the display screen, a preview image for display may be created and stored separately from the thumbnail. In the present embodiment, the thumbnail including the preview image is expressed.

  That is, these image files F1, F2, F3,... Are a general digital camera file format. Therefore, the SD card (memory card 18) imaged by the digital camera can be used simply by being inserted into the memory card slot 6.

Hereinafter, a specific operation of the DPF 1 in the effect mode will be described.
FIG. 5 is a flowchart showing a main routine in the processing procedure of the CPU 11 when the effect mode is set in the first embodiment. When the effect mode is set, the CPU 11 executes processing as shown in this flowchart according to the program stored in the ROM 12.

  First, the CPU 11 reads the thumbnail image data of the image files F1 to F16 to be displayed from the memory card 18. Then, based on these thumbnail image data, thumbnails are displayed on the liquid crystal display panel 3 (step S101). Therefore, as a result of the processing in step S101, thumbnails 1 to 16 are displayed as a list on the liquid crystal display panel 3, as shown in FIG. At this time, the CPU 11 also displays a batch conversion button 301 and a page feed button 302 at the lower end corner of the liquid crystal display panel 3.

  Therefore, by operating the page feed button 302, it is possible to read out 16 different thumbnails from the memory card 18 and change the thumbnails displayed on the liquid crystal display panel 3. The page may be turned by sliding the screen with a finger without providing a button.

  Based on the output from the touch panel 22, it is determined whether or not the batch conversion button 301 of the batch conversion button 301 and the page feed button 302 displayed at the lower corner of the liquid crystal display panel 3 has been touched by the user ( Step S102).

  When the batch conversion button 301 is not touched, the process proceeds from step S102 to step S107, and it is determined whether or not any thumbnail is touched. If not touched, the processing from step S102 is repeated.

  However, in a state where thumbnails 1 to 16 are displayed on the liquid crystal display panel 3, when the user touches any one of the thumbnails, this is detected by the touch panel 22, and the CPU 11 determines YES in step S107. Then, the CPU 11 proceeds to step S108 and determines whether or not the image tone converted data has already been recorded in the memory card 18.

  In step S109 following step S108, the image tone conversion process is executed for the one-touched thumbnail. That is, as shown in FIG. 7A, it is assumed that the user has touched the thumbnail 7 and the thumbnail 8 with one touch in a state where the thumbnails 1 to 16 are displayed (the same state as FIG. 6). Then, since the oil painting tone is “(1)” in the priority order, the thumbnail 7 and the thumbnail 8 are subjected to the image tone conversion processing in the oil painting tone.

  At this time, as will be described later, the image data of the thumbnail 7 and the thumbnail 8 that have been converted into an oil painting-like image may already be stored in the memory card 18. Therefore, in step S108, it is determined whether or not there is image data in which the thumbnail is converted into an oil painting tone in the memory card 18, and only when there is no image data (oil painting tone) conversion for the one-touch thumbnail. Processing is executed (step S109).

  In this tone conversion process, the CPU 11 extracts features such as color information and brush information from the original picture of the oil painting actually drawn by the painter stored in the ROM 12, and adds the extracted features to the thumbnail 7. Then, the image conversion processing is performed on the thumbnail 8 to generate converted image image data, and an oil painting image converted image image is created from the generated converted image image data. Then, the image data of the painting-style conversion thumbnail generated in the process of step S109 is written and stored in the corresponding file of the memory card 18 (step S110).

  Thereafter, in place of the oil painting tone 7 and the oil painting tone 8 currently displayed on the liquid crystal display panel 3, the oil painting tone converted painting image is replaced and displayed (step S111). Therefore, by the processing in step S111, the display screen of the liquid crystal display panel 3 changes from the state shown in FIG. 7A to the state shown in FIG. 7B, and the thumbnail 7 is displayed on the liquid crystal display panel 3. , 8, oil painting styles 7 and 8 are displayed.

  Subsequently, it is determined whether or not a double touch (two consecutive touches) has been made on any thumbnail (step S112). When the double touch is not performed, the process returns to step S107. Accordingly, it is assumed that the user has touched the oil painting tone 8 in the display state shown in FIG. 8A (the display state similar to FIG. 7B). Then, since the priority order is (1) oil painting tone is next to (2) watercolor painting tone, the thumbnail 8 corresponding to the oil painting tone 8 is subjected to the painting tone conversion processing in the watercolor painting tone.

  At this time, the memory card 18 may already store image data obtained by converting the thumbnail 8 into a watercolor image. Therefore, in step S108, it is determined whether or not there is image data in which the thumbnail 8 is converted into a watercolor painting tone in the memory card 18, and only when there is no thumbnail 8 corresponding to the oil painting tone 8 touched one by one. Then, another image tone (watercolor image tone) conversion process is executed (step S109).

  During this tone conversion process, the CPU 11 extracts features such as color information and brush stroke information from the original watercolor image actually drawn by the painter stored in the ROM 12, and adds the extracted features to the thumbnail 8. The image conversion processing is performed on the image to generate converted image image data, and a converted image image of a watercolor image is created from the generated converted image image data. Then, the image data of the painting-style conversion thumbnail generated in the process of step S109 is written and stored in the corresponding file of the memory card 18 (step S110).

  Thereafter, instead of the oil painting tone 8 currently displayed on the liquid crystal display panel 3, the converted painting tone image of the watercolor painting is replaced and displayed (step S111). Therefore, by the processing in step S111, the display screen of the liquid crystal display panel 3 changes from the state shown in FIG. 8A to the state shown in FIG. Instead of 8, a watercolor style 8 is displayed.

  Therefore, if the touch on the desired thumbnail is repeated, the thumbnail sequentially changes from “(1) oil painting tone” to “(8) airbrush painting tone”. Therefore, the user can not only view an image that has been subjected to desired image tone conversion quickly, but also can easily select which image to convert to which image tone image.

  Subsequently, it is determined whether or not a double touch (two consecutive touches) has been made on any thumbnail (step S112). When the double touch is not performed, the process returns to step S107. Accordingly, it is assumed that the user has touched the watercolor style 8 in the display state shown in FIG. 9A (the display state similar to FIG. 8B). Then, since the priority order is (2) the watercolor painting tone is next to (3) pastel painting, if there is no data, the thumbnail 8 corresponding to the watercolor painting 8 is subjected to the painting transformation processing with the pastel painting ( Step S109).

  That is, features such as color information and handwriting information are extracted from the original pastel image actually drawn by the painter stored in the ROM 12, and the tone conversion processing is performed on the thumbnail 8 by adding the extracted features. Then, converted image-tone image data is generated, and a pastel image-tone converted image image is created from the generated converted image-tone image data.

  Then, after the data is saved (step S110), the created pastel-tone converted image is replaced and displayed in place of the watercolor image 8 currently displayed on the liquid crystal display panel 3 (step S111). Therefore, by the processing in step S111, the display screen of the liquid crystal display panel 3 changes from the state shown in FIG. 9A to the state shown in FIG. Instead of 8, pastel image style 8 is displayed.

  At this time, since the CPU 11 converts the tone of the thumbnail having a data amount much smaller than that of the main image, the conversion process does not take time. Accordingly, the user can quickly see an image (oil painting tone 7, watercolor painting tone 8 or pastel painting tone 8) that has undergone desired painting tone conversion.

  In addition, it is possible to easily select which image is to be converted to which image tone image by a one-touch operation. Therefore, various conversions can be tried on the spot to determine which image tone is the optimal conversion for the main image corresponding to the thumbnail.

  In this way, when the user double-touches any one of the image adjustment images in a state where a plurality of image adjustments desired by the user are displayed, this is detected by the touch panel 22, and the CPU 11 determines YES in step S112. To do. Therefore, the CPU 11 advances the process from step S112 to step S113, and determines whether or not data is already recorded on the memory card 18.

  That is, in step S114 following step S113, the tone conversion process is executed with the touched image tone on the image of the present application corresponding to the thumbnail of the image image double-touched. At this time, image data obtained by subjecting the main image to the tone conversion may already be stored in the memory card 18. Accordingly, in step S113, it is determined whether or not there is image data obtained by subjecting the image of the present application corresponding to the thumbnail of the tone image double-touched to the memory card 18, and only when there is no image data, step S114 and step S115 are performed. Execute the process.

  First, an image conversion process is executed on the image of the present application corresponding to the thumbnail of the image image that has been double-touched (step S114).

  For example, as shown in FIG. 10A, in a state where thumbnails 1 to 6 and 9 to 16, oil painting tone 7 and pastel painting tone 8 are displayed (display state similar to FIG. 9B), the user Suppose that pastel painting style 8 is double-touched. Then, the CPU 11 first searches the RAM 13 for the file F8 in which the thumbnail 8 corresponding to the pastel image tone 8 is recorded, and reads the main image 8 from the searched file F8. Also, since the watercolor style 8 has been double-touched, the picture style to be converted is the watercolor style, and therefore the main image 8 is subjected to the paint tone conversion process with the pastel style.

  That is, a feature conversion process is performed on the main image 8 by extracting features such as color information and handwriting information from the original pastel image actually drawn by the painter stored in the ROM 12, and adding the extracted features. Is performed to generate converted image-tone image data, and a pastel image-tone converted image image is created from the generated converted image-tone image data.

  Subsequently, the image data of the painting-like converted main image generated in the process of step S114 is written and stored in the corresponding file of the memory card 18 (step S115). Therefore, by the processing in step S114, as shown in FIG. 4, the painting-like converted master image 8 obtained by painting-converting the master image is added to the file F8 and stored. Accordingly, it is possible to prevent unnecessary processing from being performed again to create the same original painting-style conversion main image by an interrupt routine described later.

  Then, instead of the thumbnails 1 to 6 and 9 to 16, the oil painting tone 7, and the pastel painting tone 8 currently displayed on the liquid crystal display panel 3, the converted painting tone image of the created pastel painting main image 8 is displayed on the full screen. Displayed (step S116). Therefore, by the processing in step S116, the display screen of the liquid crystal display panel 3 is changed from the state shown in FIG. 10A to the state shown in FIG. The pastel image 8 that is the 8 pastel images is displayed.

  Therefore, it is possible not only to easily select which image to be converted to which tone image by one-touch operation, but also to try various conversions on the spot, and finally to the conversion tone that is determined to be appropriate. The tone of the main image can be converted.

  On the other hand, if it is determined in step S102 that the batch conversion button 301 has been touched, the process proceeds from step S102 to step S103 to determine whether data has already been recorded on the memory card 18 or not.

  That is, in step S104 following step S103, each thumbnail currently displayed on the liquid crystal display panel 3 is subjected to a tone conversion process in a predetermined tone according to the priority order. Here, in the present embodiment, a program for converting into eight types of painting tone from oil painting to airbrush painting is stored, but the priority order is (1) oil painting, ( 2) watercolor painting, (3) pastel painting, (4) pencil painting, (5) crayon painting, (6) illustration painting, (7) dot painting, and (8) airbrush painting. Therefore, in accordance with the first operation of the batch conversion button 301, the image conversion process is performed in “(1) oil painting tone”.

  At this time, there may be a case where image data that has been converted into oil painting is already stored in the memory card 18. Therefore, in step S103, it is determined whether or not there is image data obtained by converting the thumbnail into an oil painting tone in the memory card 18, and a thumbnail having no image data converted into an oil painting tone is selected according to the priority order. Image tone conversion processing is performed in (oil painting tone) (step S104).

  That is, there is no image data converted by oil painting by extracting features such as color information and handwriting information from the original picture of the oil painting actually drawn by the painter stored in the ROM 12, and adding the extracted features. An image tone conversion process is performed on the thumbnails to generate converted image image data, and an oil image-like converted image image is created from the generated converted image image data.

  Subsequently, the image data of the painting-like conversion thumbnail generated in the process of step S104 is written and stored in the corresponding file of the memory card 18 (step S105). Therefore, by the processing in step S105, as shown in FIG. 3B, the painting-style conversion thumbnails are added to the files F1 to F16 and stored. Accordingly, it is possible to prevent unnecessary processing for creating the same picture-tone conversion thumbnail again in the interrupt routine described later.

  Then, instead of the thumbnails 1 to 16 currently displayed on the liquid crystal display panel 3, an oil painting-like converted image is displayed (step S106). Therefore, by the processing in step S106, the display screen of the liquid crystal display panel 3 changes from the state shown in FIG. 11A to the state shown in FIG. Therefore, the converted picture image of oil picture tone 1 to oil picture tone 16 is displayed. Therefore, the user can quickly view all the images corresponding to the thumbnail images that have been subjected to the tone conversion in oil painting tone.

  When the batch conversion button 301 is not touched, the process proceeds from step S102 to step S107, and it is determined whether or not any thumbnail is touched. If not touched, the processing from step S102 is repeated. Therefore, when the user touches the batch conversion button 301 again in the display state shown in FIG. 12A (the display state similar to FIG. 11B), “ The image conversion process is executed in “(2) watercolor style” (step S104).

  For this reason, the display screen of the liquid crystal display panel 3 changes from the state shown in FIG. 12A to the state shown in FIG. 12B by the processing in step S106, and the liquid crystal display panel 3 corresponds to the thumbnail. The converted image of the watercolor tones 1 to 16 is displayed. Therefore, the user can quickly see all the images corresponding to the thumbnail images that have been subjected to the tone conversion in the watercolor tone.

  Here, there may be a case where different thumbnails are displayed on the displayed thumbnails. For example, in FIG. 11A, assuming that the batch conversion button 301 is operated in a state where the thumbnail 7 is displayed in oil painting style and the thumbnail 8 is displayed in pastel painting style as shown in FIG. In accordance with the priority order, the whole is converted into an oil painting tone, the thumbnail 7 is converted into a watercolor painting tone, and the thumbnail 8 is converted into a pencil painting tone.

On the other hand, the CPU 11 interrupts the main routine at regular time intervals and executes interrupt processing according to the flowchart shown in FIG. That is, it is determined whether it is a predetermined timing (step S201).
Here, as an example of whether or not it is a predetermined timing,
1) Whether it is a predetermined time based on the time counted by the CPU 11, for example, whether it is between 2 o'clock and 3 o'clock at midnight,
2) Whether it is a timing when there is no human being around the DPF 1 for a predetermined time or more based on a signal from the human sensor 14), or 3) A timing when the power is turned off.

  If it is determined that it is not the predetermined timing, the process returns to the main routine without executing the subsequent processing. If the predetermined timing is determined, output of the image data to the liquid crystal display panel 3 is stopped (step S202), and then it is determined whether there is an image being converted (step S203). If it is determined that there is an image in the middle of conversion, the image data in the middle of conversion stored in the RAM 13 and data indicating how far the image has been converted are read and the rest of the conversion is executed (step S204). . Therefore, by canceling the output of the image data to the display device in step S202, the following conversion process can be completed in a short time with the burden on the CPU 11 reduced.

  If it is determined in step S203 that there is no image being converted, it is determined whether there is image data that has not yet been converted in the memory card 18 (step S205). If it is determined that there is no unconverted image data, the process returns to the main routine. On the other hand, if it is determined in step S205 that unconverted image data (main image and thumbnail) exists, a conversion program corresponding to the conversion determined after the conversion type is determined according to the priority order (1) to (8). Is executed to convert the tone of the image data (steps S206 and S207).

  That is, the image tone conversion of each image tone (1) to (8) is sequentially performed on the thumbnails 1 to 16 of the files F1 to F16, and each of the main images 1 to 16 of the files F1 to F16 is sequentially performed. The image tone conversion of the image tone (1) to (8) is performed. Thereafter, the image data of the converted image-tone image generated in step S204 or step S207 is stored and stored in the corresponding files F1 to F16 (step S208).

  Subsequently, it is determined whether or not all types of conversion have been completed (step S209). If it is determined that all types of conversion have not been completed, the process returns to step S206 to determine the next conversion type and execute the conversion. If it is determined in step S209 that all types of conversion have been completed, the automatic conversion process ends.

  By performing the interrupt process in this way, when the user inputs a conversion command to view the image after the conversion process, the conversion process is completed by reading out and displaying the already converted image data. It is possible to quickly view an image having undergone a desired conversion without waiting.

  In the present embodiment, thumbnails 1 to 16 are displayed on the liquid crystal display panel 3, and the touched thumbnail is designated as an image to be subjected to the tone conversion. However, when the main images are sequentially displayed and touched The main image displayed in (1) may be designated as an image to be converted.

(Second Embodiment)
FIG. 14 is a system configuration diagram showing the configuration of the image tone conversion service system according to the second embodiment of the present invention. In the figure, a DPF 1 functioning as a terminal has the same configuration as that of the first embodiment shown in FIGS. Therefore, the DPF 1 includes the antenna 21 and the wireless communication unit 20 and has an information transmission / reception function.

  However, unlike the first embodiment, the ROM 12 of the DPF 1 has oil paintings, watercolor paintings, pastel paintings, pencil paintings, crayon paintings, illustration paintings, dot paintings, airbrush paintings, and converted paintings based on these original paintings. The conversion image tone image creation program for creating an image is not stored, and its type and priority order (1) oil painting tone, (2) watercolor painting tone, (3) pastel painting tone, (4) pencil painting tone, (5) Only crayon strokes, (6) illustration strokes, (7) point drawing strokes, and (8) airbrush strokes are stored. The radio base station 30 connects the DPF 1 to a communication service company (including an Internet provider) 40 to which the DPF 1 subscribes.

  The communication service company 40 includes a system (Web server 43) and a mail system (mail server 42) for connecting to a WWW (Internet) 50, which will be described later, in addition to the communication circuit processing unit 41 required for the communication service. . Also, a function for connecting the DPF 1 to the WWW 50 using the wireless base station 30 as an AP (access point) is provided. The image tone conversion service company 60 includes a system (Web server 61) for connecting to the WWW 50 and a management server 63.

  FIG. 15 is a block diagram showing details of the management server 63, and the Web server 61 is connected to the management server 63 via a hub 64. The management server 63 includes an input operation unit (keyboard, mouse, etc.) 631, a control unit (main frame) 632, a system program storage unit 633, a user management table 634, a display unit 635, and a communication control unit 636, which are mutually connected via a system bus. It is a connected system. Then, for the DPF 1 operated by the registrant registered in the user management table 634, a service for converting the received image and transmitting it is performed for a fee or free of charge.

  The system program storage unit 63 stores a program for causing the control unit 632 to perform an operation shown in a flowchart described later. In the system program storage unit 63, oil paintings, watercolor paintings, pastel paintings, pencil paintings, crayon paintings, illustration paintings, dot paintings, and airbrush paintings actually drawn by the painter, and color information and touch information from these original paintings. And the like, and by applying the extracted features, image conversion processing is performed on the input image to create a converted image image, which is disclosed in Japanese Patent Application Laid-Open No. 2004-213598. The program is also stored.

  Next, the operation of this embodiment will be described with reference to FIGS. The CPU 11 of the DPF 1 executes processing based on the program stored in the ROM 12 as shown in the flowchart of FIG. The management server 63 connected to the DPF 1 executes processing as shown in the flowchart of FIG. 17 based on the program stored in the system program storage unit 633.

  That is, in the effect mode, as shown in the flowchart of FIG. 16, the CPU 11 reads out the image files F1 to F16 from the memory card 18 for the image data to be displayed, and images of the image files F1 to F16 thumbnails 1 to 16. Read data. Based on the thumbnail image data, the thumbnail is displayed on the liquid crystal display panel 3 (step SA1). Therefore, as a result of the processing in step SA1, thumbnails 1 to 16 are displayed as a list on the liquid crystal display panel 3, as shown in FIG. At this time, the CPU 11 also displays a batch conversion button 301 and a page feed button 302 at the lower end corner of the liquid crystal display panel 3.

  Then, it is determined based on the output from the touch panel 22 whether or not the batch conversion button 301 has been touched by the user's finger (step SA2). If the batch conversion button 301 is touched, it is determined whether or not data is already recorded in the memory card 18 (step SA3).

  That is, in step SA4 following step S103, the management server 63 performs a tone conversion process on each thumbnail (thumbnail 1 to 16) currently displayed on the liquid crystal display panel 3 in a predetermined tone according to the priority order. Send to. Here, the priority order is (1) oil painting, (2) watercolor painting, (3) pastel painting, (4) pencil painting, (5) crayon painting, (6) illustration painting, (7) point drawing tone, (8) airbrush painting tone. Therefore, in accordance with the first operation of the batch conversion button 301, the image conversion process is performed in “(1) oil painting tone”.

  At this time, as will be described later, there may be a case where image data that has been converted into an oil painting is already stored in the memory card 18. Therefore, in step SA3, it is determined whether or not there is image data obtained by converting the thumbnail into the oil painting tone in the memory card 18, and the thumbnail without the image conversion is determined according to the priority order. ), The thumbnail and the type of image tone to be converted (one of (1) to (8), (1) oil painting tone) are transmitted to the management server 63 at this time). At this time, since none of the files F1 to F16 corresponding to the thumbnails 1 to 16 has the image data converted into the oil painting tone, the thumbnails 1 to 16 are transmitted together with the painting type “oil painting tone”. It will be.

  On the other hand, as shown in the flowchart of FIG. 17, the management server 63 determines whether or not a thumbnail and an image tone type have been received (step SB1). If the thumbnail (thumbnail 1 to 16) and the type of image tone are received, the received thumbnail is subjected to image tone conversion processing with the received image type (step SB2).

  That is, the extracted thumbnail (thumbnail) is obtained by extracting features such as color information and handwriting information from the original picture of the oil painting actually drawn by the painter stored in the system program storage unit 633 and adding the extracted features. 1 to 16) is subjected to image tone conversion processing to generate converted image image data, and an oil image-like converted image image is created from the generated converted image image data. Subsequently, the image data of the painting-like conversion thumbnail generated in the process of step SA2 is transmitted to the DPF 1 (step SB3).

  Then, the CPU 11 of the DPF 1 receives the image data via the wireless communication unit 20 (step SA5), writes it in a corresponding file on the memory card 18 and stores it (step SA6). Therefore, by the processing in step SA6, as shown in FIG. 3B, the painting-style conversion thumbnails are added to the files F1 to F16 and stored. Accordingly, it is possible to prevent unnecessary processing from being performed in order to generate the same picture-tone conversion thumbnail again in the interrupt routine described later.

  Then, instead of the thumbnails 1 to 16 currently displayed on the liquid crystal display panel 3, an oil painting-like converted picture image is displayed (step SA7). Therefore, by the processing in step SA7, the display screen of the liquid crystal display panel 3 changes from the state shown in FIG. 11A to the state shown in FIG. Therefore, the converted picture image of oil picture tone 1 to oil picture tone 16 is displayed. Therefore, the user can quickly view all the images corresponding to the thumbnail images that have been subjected to the tone conversion in oil painting tone.

  In step SA8 following step SA7, it is determined whether any one of the thumbnails has been touched. If not, the processing from step SA2 is repeated. Therefore, when the user touches the batch conversion button 301 again in the display state shown in FIG. 12A, the thumbnail and the painting type “watercolor painting” are managed according to the second batch conversion button 301 operation. It is transmitted to the server 63 (step SA4).

  Further, the management server 63 transmits image data obtained by converting the thumbnail into a watercolor painting. Therefore, the display screen of the liquid crystal display panel 3 is changed from the state shown in FIG. 12A to the state shown in FIG. 12B by the processing in step SA7, and the liquid crystal display panel 3 corresponds to the thumbnail. The converted painting-tone images of the watercolor painting tone 1 to the watercolor painting tone 16 are displayed. Therefore, the user can quickly see all the images that have been subjected to the painting tone conversion in the watercolor painting tone.

  As described above, when the user touches one of the converted image-tone images while the converted image image is displayed, this is detected by the touch panel 22, and the CPU 11 determines YES in step SA8. Then, the CPU 11 determines whether or not data is already recorded on the memory card 18 (step SA9).

  That is, in step SA10 following step SA9, transmission is performed on the one-touched thumbnail in order to execute another image tone conversion process. That is, as shown in FIG. 7A, it is assumed that the user has touched thumbnail 7 and thumbnail 8 with one touch while thumbnails 1 to 16 are displayed. Then, since the oil painting tone is “(1)” in the priority order, the thumbnail 7 and the thumbnail 8 are transmitted for the image tone conversion processing in the oil painting tone.

  At this time, as will be described later, there may be a case where image data that has been converted into an oil painting is stored in the memory card 18. Therefore, in step SA8, it is determined whether or not there is image data obtained by converting the thumbnail into an oil painting tone in the memory card 18. Only when there is no thumbnail, the thumbnail corresponding to the one-touched tone image and the thumbnail are displayed. The image type to be converted is transmitted (step SA10).

  As shown in the flowchart of FIG. 1, the management server 63 determines whether or not the thumbnail and the type of image tone have been received (step SB1). When the thumbnail and the type of image tone are received, the tone conversion processing is performed with the received image type of the received thumbnail (step SB2).

  That is, the extracted thumbnail (thumbnail) is obtained by extracting features such as color information and handwriting information from the original picture of the oil painting actually drawn by the painter stored in the system program storage unit 633 and adding the extracted features. 7 and 8) is subjected to image tone conversion processing to generate converted image image data, and a watercolor image converted image image is created from the generated converted image image data. Subsequently, the image data of the painting-like conversion thumbnail generated by the process of step SB2 is transmitted to the DPF 1 (step SB3).

  Then, the CPU 11 of the DPF 1 receives the image data via the wireless communication unit 20 (step SA11), writes it in a corresponding file on the memory card 18 and stores it (step SA12). Therefore, by the processing in step SA6, as shown in FIG. 3B, the painting-style conversion thumbnails are added to the files F1 to F16 and stored. Accordingly, it is possible to prevent unnecessary processing from being performed in order to generate the same picture-tone conversion thumbnail again in the interrupt routine described later.

  After that, instead of the thumbnail 7 and the thumbnail 8 currently displayed on the liquid crystal display panel 3, the oil painting-like converted picture image is replaced and displayed (step SA13). Therefore, by the processing in step SA13, the display screen of the liquid crystal display panel 3 changes from the state shown in FIG. 7A to the state shown in FIG. 7B, and the thumbnail 7 is displayed on the liquid crystal display panel 3. , 8, oil painting styles 7 and 8 are displayed.

  Subsequently, it is determined whether or not a double touch (two consecutive touches) has been made on any thumbnail (step SA14). If double touch is not performed, the process returns to step SA8. Accordingly, it is assumed that the user has touched the oil painting tone 8 in the display state shown in FIG. Then, since the priority order is (1) oil painting tone is next to (2) watercolor painting tone, when there is no data, the thumbnail 8 corresponding to the oil painting tone 8 is subjected to the painting tone conversion processing in the watercolor painting tone. Transmission is performed on the DPF 1 side (step SA11), and conversion processing is performed on the management server 63 side (step SB2).

  That is, the management server 63 extracts features such as color information and handwriting information from a watercolor original picture actually drawn by a painter stored in the system program storage unit 633, and adds the extracted features to the thumbnail 8. The image conversion process is performed on the image to generate converted image image data, and a converted image image of a watercolor image is created from the generated converted image image data. Thereafter, this data is transmitted (step SB3).

  Then, the DPF 1 receives this (step SA11), saves the data (step SA12), and then replaces the oil painting tone 8 currently displayed on the liquid crystal display panel 3 with the created pastel painting conversion image. The toned image is replaced and displayed (step SA13). Therefore, by the processing in step SA11, the display screen of the liquid crystal display panel 3 changes from the state shown in FIG. 8B to the state shown in FIG. Instead of 8, pastel image style 8 is displayed.

  At this time, since the CPU 11 only transmits and receives data without performing the image tone conversion process, the process does not take time. Therefore, the user can quickly see an image that has undergone desired tone conversion.

  In addition, it is possible to easily select which image is to be converted to which image tone image by a one-touch operation. Therefore, various conversions can be tried on the spot to determine which image tone is the optimal conversion for the main image corresponding to the thumbnail.

  As described above, when a user double-touches any image adjustment image in a state where a plurality of image adjustments desired by the user are displayed, this is detected by the touch panel 22, and the CPU 11 determines YES in step SA14. To do. Therefore, the CPU 11 advances the process from step SA14 to step SA15, and determines whether or not data has already been recorded on the memory card 18.

  That is, in step SA16 following step S115, data transmission is executed to perform a tone conversion process with the touched image tone on the image of the present application corresponding to the thumbnail of the image image double-touched. At this time, image data obtained by subjecting the main image to image conversion may be stored in the memory card 18. Therefore, in step SA13, it is determined whether or not there is image data obtained by subjecting the image of the present application corresponding to the thumbnail of the tone image double-touched to the memory card 18, and only when there is no image data of steps SA16 to SA18. Execute the process.

  First, the image of the present application corresponding to the thumbnail of the double-touched image tone image and the image tone type to be converted are transmitted (step SA16).

  That is, as shown in FIG. 10A, it is assumed that the user double-touches the pastel 8 when the pastel image tone 8 is displayed. Then, the CPU 11 first searches the RAM 13 for the file F8 in which the thumbnail 8 corresponding to the pastel image tone 8 is recorded, and reads the main image 8 from the searched file F8. Further, since the pastel image tone 8 is double-touched, the image tone to be converted is the pastel image tone, and the type to be modulated is determined as “pastel image tone”. Then, the read main image 8 and the type of modulation “pastel painting” are transmitted to the management server 63.

  On the other hand, as shown in the flowchart of FIG. 15, the management server 63 determines whether or not the main image and the type of image tone have been received (step SB4). If the main image (main image 8) and the type of image tone (watercolor image) are received, the received image is subjected to image tone conversion processing with the received image type (step SB5).

  That is, by extracting features such as color information and handwriting information from an original picture of an oil painting actually drawn by a painter stored in the system program storage unit 633, the extracted features are added to the received main image. The image conversion processing is performed on the image to generate converted image image data, and a converted image image of a watercolor image is created from the generated converted image image data. Subsequently, the image data of the painting-like converted main image generated by the process of step SB5 is transmitted to the DPF 1 (step SB6).

  Then, the DPF 1 receives the image data transmitted from the management server 63 (step S17), and writes the image data of the received painting-style conversion main image in a corresponding file in the memory card 18 and stores it (step SA18). Therefore, by the processing in step SA18, as shown in FIG. 4, the master image 8 that has been subjected to painting-like conversion is added to the file F8 and stored. Thereby, it is possible to prevent unnecessary transmission / reception processing for generating the same painting-style converted main image again by an interrupt routine described later.

  Then, instead of the watercolor tones 1 to 16 currently displayed on the liquid crystal display panel 3, the converted image of the main image 8 in pastel tones is displayed on the full screen (step SA19). Therefore, by the processing in step SA16, the display screen of the liquid crystal display panel 3 is changed from the state shown in FIG. 10A to the state shown in FIG. The pastel image 8 that is the 8 pastel images is displayed.

  Therefore, it is possible not only to easily select which image to be converted to which tone image by one-touch operation, but also to try various conversions on the spot, and finally to the conversion tone that is determined to be appropriate. The tone of the main image can be converted.

  Further, the CPU 11 of the DPF 1 interrupts the main routine at regular time intervals and executes interrupt processing according to the flowchart shown in FIG. That is, it is determined whether it is a predetermined timing (step SA21). Here, whether or not it is a predetermined timing is the same as in the first embodiment described above.

  If it is determined that it is not the predetermined timing, the process returns to the main routine without executing the subsequent processing. If the predetermined timing is determined, output of the image data to the liquid crystal display panel 3 is stopped (step SA22), and then the memory card 18 is searched for a thumbnail that has not been subjected to the tone conversion yet. Whether or not (step SA23). If there is a thumbnail that has not yet undergone image tone conversion, the thumbnail and the type of image tone that has not undergone image tone conversion are transmitted (step S24).

  Further, the memory card 18 is searched to determine whether or not there is a main image that has not been subjected to image tone conversion (step SA25). If there is a main image that has not yet undergone image tone conversion, the main image and the type of image tone that has not been subjected to image tone conversion are transmitted (step S26).

  Then, the control unit 632 of the management server 63 executes the process according to the flowchart of FIG. 15 as described above and receives the type of thumbnail and image tone (step SB1; YES), the type of received thumbnail. Is converted (step SB2), and the image-converted data is transmitted (step SB3). When the main image and the type of image tone are received (step SB4; YES), the received main image is converted with the received image type (step SB5), and the image tone converted data is transmitted (step SB5). Step SB6).

  Then, the CPU 11 of the DPF 1 receives the data transmitted from the management server 63 (step SA27), and stores the received data in the corresponding files F1 to F16 (step S28).

By performing the interrupt process in this way, when the user inputs a conversion command to view the image after the conversion process, the conversion process is completed by reading out and displaying the already converted image data. It is possible to quickly view an image having undergone a desired conversion without waiting.
