Description

  The present invention relates to an image display device, an image display method, and a program, and more particularly to a technique for converting an image into an image having a different 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.

  On the other hand, in such a digital photo frame, there are many cases where time is always displayed. If the main body is shaped like a desktop clock (table clock), it can also be used as an image display clock capable of displaying images.

  Generally, a digital photo frame can use a memory card such as an SD card. Therefore, if a memory card slot is also provided in the image display clock, the recorded image data can be displayed or the time background can be displayed. It is also possible to display it.

  FIG. 2B is a perspective view showing the image display timepiece 10 configured in a table clock shape. 20 is a main body, 6 is a card slot, 3 is a liquid crystal display panel, and a time display 303 is usually provided. The electrical configuration of the image display timepiece 10 is substantially the same as that of the image display device 1 and thus will not be described. However, the function of the radio timepiece is incorporated, and the time display 303 is held at an appropriate time. Reference numeral 40 denotes a dial which is used for time adjustment of a clock. 70 is a mode key, 71 is a clock mode key, 72 is a normal mode (photo frame mode), and 73 is a key for designating an effect mode. 80 is a cursor key for designating the top, bottom, left and right of the screen. 90 is a batch conversion key for batch-tone conversion of images displayed in the effect mode, and 91 is a confirmation key.

  FIG. 2 is a block diagram showing an electrical configuration of the image display apparatus 1. The image display device 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, and an Ir data receiving module 14 including the infrared signal receiving unit 4. , A display controller 16, a memory card controller 17, a touch panel 19, and a 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 Ir data receiving module 14 demodulates the infrared signal from the remote controller 100 received by the infrared signal receiver 4, and supplies the instruction content corresponding to the key operation on the remote controller 100 to the CPU 11.

  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 and data processing according to the communication protocol.

  In addition, the image display device 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 102 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 digital photo frame (DPF).

  The image that can be displayed on the image display device 1 is, for example, an image captured by a digital camera, 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. It is an image. 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, the type of painting that is a target for conversion to a painting-like image, that is, the feature (painting) to be converted into a painting-like image can be selected. 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 each of the embodiments, a program for converting into eight types of painting from oil painting to airbrush painting is stored. 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. The memory card 18 is detachably attached to the digital camera, and is provided with a folder A shown in FIG. 3A and a folder B shown in FIG. In the folder A, a large number of images are filed in the JPEG file format along with photographing with the digital camera and recorded as image files F1, F2, F3. Each image file F1, F2, F3,... Has a header having data such as EXIF (Exchangeable Image File Format), and image data that is a captured image and is a main image (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.

  Also, in the folder B, image data including a picture-like conversion thumbnail is compressed by a JPEG method, which is a general-purpose file format, by a process to be described later, and stored as a still image file together with additional information such as a conversion date and time.

  Hereinafter, a specific operation of the image display apparatus 1 in the effect mode of the present embodiment will be described.

  FIG. 4 is a flowchart showing a processing procedure of the CPU 11 when the effect mode is set in the present 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 thumbnail image data from each of the four image files to be displayed from the folder A of the memory card 18 (step S101). Then, the four thumbnail image data thus read out are subjected to a tone conversion process with three types of tone (step S102). That is, since the priority order is (1) oil painting tone, (2) watercolor painting tone, and (3) pastel painting tone, the four thumbnails are respectively subjected to the painting tone conversion processing in oil painting tone, watercolor painting tone, and pastel painting tone. Accordingly, if the thumbnails 1 to 4 are read from the files F1 to F4 in step S101 at this time, the thumbnails 1 to 4 are subjected to the tone conversion processing in oil painting, watercolor painting, and pastel painting, respectively.

  Subsequently, a total of four images including the corresponding thumbnail and the three tone conversion images are displayed in the row direction on the liquid crystal display panel 3 (step S103). Therefore, if the thumbnails 1 to 4 are read and subjected to the tone conversion processing in the oil painting tone, the watercolor painting tone, and the pastel painting tone, the liquid crystal display panel 3 is shown in FIG. Display state.

  That is, the thumbnails 1 to 4 are displayed in the column direction on the left end of the liquid crystal display panel 3 and, for example, corresponding to the thumbnail 1, the painting-tone conversion images “oil painting tone 1”, “watercolor painting tone 1”, “pastel” “Picture 1” is displayed in the row direction. The other thumbnails 2, 3, and 4 are the same, and correspondingly, the oil-tone-like images 2, 3, 4, “Watercolor-tone 2, 3, 4”, “Pastel” Keys 2, 3, 4 "are displayed in the row direction.

  At this time, the CPU 11 causes the liquid crystal display panel 3 to display a lower page advance button 301, a right page advance button 302, an upper page advance button 303, and a left page advance button 304.

  In the present embodiment, the X direction in the plane coordinates is referred to as the row direction, and the Y direction is referred to as the column direction.

  In this state, it is possible to perform a touch slide operation with a finger, or to send to the lower page by the lower page feed button 301 (arrow X), or to send to the right page by the right page feed button 302 (arrow Y).

  That is, in step S104 following step S103, it is determined whether or not the right page advance button 302 has been touched. If the right page feed button 302 is not touched, it is determined whether or not the lower page feed button 301 is touched (step S105). If the lower page feed button 301 is touched, the process returns to step S101.

  When the page is turned downward (step S105; YES), the process proceeds to the thumbnail display of the next image. That is, the flowchart of FIG. 4 is repeated, and the CPU 11 reads thumbnail image data from the next four image files to be displayed from the folder A of the memory card 18 (step S101). At this time, if the thumbnails 1 to 4 are read from the files F1 to F4 in the previous process, the thumbnails 5 to 8 are read from the files F5 to F8 in the current process. Then, the thumbnails 5 to 8 are subjected to the tone conversion processing in the oil painting tone, the watercolor painting tone, and the pastel painting tone (step S102) and displayed (step S103).

  Therefore, the liquid crystal display panel 3 changes from the state of FIG. 5A to the state of FIG. 5B, and thumbnails 5 to 8 are displayed in the column direction on the left end. Tone conversion images “oil painting tone 5”, “watercolor painting tone 5”, and “pastel painting tone 5” are displayed in the row direction. The other thumbnails 6, 7, and 8 are also the same, and the corresponding image-tone conversion images “oil painting tone 6, 7, 8”, “watercolor painting tone 6, 7, 8”, “pastel painting” Keys 6, 7, 8 "are displayed in the row direction.

  Therefore, not only can the image subjected to the desired image tone conversion be quickly viewed, but also it is possible to easily select which image is to be converted into which image tone image.

  When the page is turned rightward (step S104; YES), different types of image tone conversion are performed on the same thumbnail image data.

  That is, the CPU 11 returns from step S104 to step S102, and performs the tone conversion processing of the thumbnail image data for the four images that have already been read, with the following three types of image tone. That is, since the priority order is (4) pencil drawing, (5) crayon drawing, and (6) illustration drawing, four thumbnail image data are drawn in pencil drawing, crayon drawing, and illustration drawing respectively. Convert it. Therefore, if the thumbnails 1 to 4 are read from the files F1 to F4 in step S101 at this time, the thumbnails 1 to 4 are subjected to the tone conversion processing respectively in pencil, crayon, and illustration.

  Subsequently, a total of four images including the corresponding thumbnail and the three tone conversion images are displayed in the row direction on the liquid crystal display panel 3 (step S103). Therefore, if the thumbnails 1 to 4 are read out and subjected to the tone conversion processing in the pencil, crayon, and illustration, respectively, the liquid crystal display panel 3 displays the display shown in FIG. The state (the same display state as in FIG. 5A) shifts to FIG.

  That is, the thumbnails 1 to 4 are displayed in the column direction on the left end of the liquid crystal display panel 3 and, for example, corresponding to the thumbnail 1, the image conversion images “pencil drawing 1”, “crayon drawing 1”, “ “Illustration 1” is displayed in the row direction. The other thumbnails 2, 3, and 4 are also the same, and the corresponding image conversion images, "pencil drawing 2, 3, 4", "crayon drawing 2, 3, 4", "illustration" The image tone 2, 3, 4 "is displayed in the row direction.

  Therefore, not only can the image subjected to the desired image tone conversion be quickly viewed, but also it is possible to easily select which image is to be converted into which image tone image.

  If the thumbnail is about QCIF size (176 × 144 dots), it is possible to see the nuance of image quality. If the display screen of the image display device 1 is large and the display is 3 rows and 3 columns, thumbnails of QVGA size (320 × 240 dots) are also possible.

  In the above description, when the lower page or the right page is turned, the screen is completely switched to the next page. However, the display can be shifted one line at a time downward or right. If you move the page up or page left, you will return to the previous page.

  Next, it is determined whether or not any of the images displayed in the 4 rows and 4 columns is touched (step S106).

  If it is the thumbnail 6 that has been touched, image data including an image obtained by converting the thumbnail 6 into each type of image tone is generated (step S107). Accordingly, for example, if the user touches “thumbnail 6” in the display state of FIG. 5B, all the images are “thumbnail 6”, and “oil painting tone 6” obtained by converting the tone of this “thumbnail 6” into an oil painting tone. , “Watercolor Painting 6” converted to watercolor, “Pastel Painting 6” converted to pastel, “Pencil Painting 6” converted to pencil, “Crayon Painting 6” converted to crayon, Illustration “Illustration style 6” after tone conversion, “point drawing style 6” after point drawing tone conversion, and “airbrush tone style 6” after airbrush tone conversion are created, and image data D6 is created as shown in FIG. 5C. Is generated.

  Further, the CPU 11 processes and compresses the generated image data D6 by the JPEG method (step S108). Therefore, the image data “D6.JPEG” in JPEG format is generated from the image data “D6” by the processing in step S108. The generated JPEG format image data is stored in the folder B of the memory card 18 (step S109). Therefore, as a result of the processing in step S109, the image data “D6.JPEG” in the JPEG format is stored in the folder B of the memory card 18 as illustrated in FIG.

  Since the image data “D6.JPEG” stored in the folder B is JPEG format image data, the memory card 18 is removed from the image display device 1, and the image display clock 10 or other DPF is stored. Etc., it is possible to reproduce and display the “thumbnail 6” and each modulated image obtained by converting the “thumbnail 6” into each type of image tone. Therefore, the effect that a desired image tone-converted image can be quickly viewed on the image display device 1 can also be obtained with another device, for example, the image display timepiece 10.

  When storing the image data “D6.JPEG”, the image data “D6.JPEG” is stored as a still image file having a header, and the conversion date and time, the type of the converted image tone, and the like are recorded in the header. preferable.

In the present embodiment, one thumbnail and eight types of tone conversion images are stored as one still image file. However, one row in the row direction, one column in the vertical direction, or all the screens are displayed. , Etc. can be variously changed as a single still image file.

  For example, when “thumbnail 1” is touched in the state of FIG. 6B, as shown in FIG. 6C, the image belonging to the row is “thumbnail 1”, and this “thumbnail 1” is pencil-like. The image data D1 is generated by creating “Pencil tone 1” that has undergone image tone conversion, “Crayon image tone 1” that has been converted to crayon tone, and “Illustration tone 1” that has undergone illustration tone conversion.

  Then, the CPU 11 processes and compresses the generated image data D1 by the JPEG method as described above (step S108). Therefore, the image data “D1.JPEG” in JPEG format is generated from the image data “D6” by the processing in step S108. The generated JPEG format image data is stored in the folder B of the memory card 18 (step S109). Therefore, as a result of the processing in step S109, the image data “D1.JPEG” in the JPEG format is stored in the folder B of the memory card 18 as illustrated in FIG. 3B.

  Incidentally, since the image data D6 and the image data D1 displayed on the image display device 1 are one JPEG image, the image data D6 and the image data D1 are for the purpose of quickly grasping the entire atmosphere. It cannot be selected.

  On the other hand, if it is touched not the thumbnail but the image whose tone has been converted, the determination in step S106 is NO and the determination in step S110 is YES. Therefore, the CPU 11 proceeds from step S110 to step S111, and the main image corresponding to the thumbnail corresponding to the image subjected to the tone conversion is subjected to the tone conversion with the tone and displayed.

  That is, if “oil painting tone 6” is touched in the state of FIG. 5B, the thumbnail corresponding to “oil painting tone 6” is “thumbnail 6”, and the main image corresponding to “thumbnail 6” is “ There is a “main image 6”. Therefore, the image data obtained by converting the “main image 6” in the oil painting tone is generated, and the converted painting tone image based on the image data is displayed. Subsequently, the image data obtained by subjecting the main image to the tone conversion is subjected to JPEG processing (step S108) and stored in the folder B in the same manner as described above.

  Therefore, the image obtained by performing the tone conversion of the thumbnail as described above can be used not only to quickly view the image that has been subjected to the desired tone conversion on the image display apparatus 1, but as a result of the viewing, the image having the desired tone can be obtained. It is also possible to view the corresponding main image after converting it with the above-mentioned image tone and save it.

  In the above embodiment, all the data of one screen is replaced by the page turning operation, but it is within the scope of the same technical idea even if the data is replaced by one row or one column.

  Further, the case where the row direction in the above embodiment is the column direction and the column direction is the row direction is also within the scope of the same technical idea.

In the above embodiment, each of the image files F1, F2, F3,... Includes image data (main images 1, 2, 3,. It is assumed that thumbnail image data (thumbnail 1, 2, 3,...) That is a reduced image of the image data is recorded. However, if only the captured image data (main images 1, 2, 3,...) Is recorded, the main images are read from the four files in the process of step S101, and thumbnails based on these main images are read. Should be created.
In the above embodiment, the case where the present invention is applied to a digital photo frame has been described. However, the present invention is not limited to a digital photo frame. For example, various computers, PDAs, mobile phones, The present invention can also be applied to electronic devices such as digital cameras and printers.
