The reading control unit 24 reads the image data of the memory card attached to the card slot 26 or the USB flash memory attached to the USB connector 27 and transmits it to the CPU 15.

  FIGS. 3A and 3B show that two conversion processing methods are used when the digital image data is converted into sketch-like picture-like image data in the image conversion processing unit 18 as the conversion means. It is a figure which shows an example.

  Fig. 3 (a) shows a trace of a pencil running diagonally downward as shown by three arrows a, using a digital photo image of the elephant's head and forefoot as a sketch-like painting-like image. The image after the conversion in the case of performing the normal tone conversion after the image conversion processing is shown.

  And in FIG. 3 (b), a digital photograph image obtained by photographing the elephant's head and forefoot part is used as a sketch-like painting-like image, and a pencil is run diagonally downward as shown by three arrows b. An image after conversion in the case of performing reverse tone conversion in which image conversion processing is performed so as to express a trace is illustrated.

  Originally, in a sketch drawing, the trace of running a pencil is generally slantingly downward as shown in FIG. In other words, a person is usually right-handed, the hand holding the pencil is on the right, and the trace of running the pencil is slantingly left downward. Therefore, when converting a digital photographic image into a sketch-like painting-like image, only the normal-tone conversion processing method of FIG. Nevertheless, the reason why the inverse tone conversion processing method shown in FIG. 3B is also used in this example will be described below.

  4A is a digital photographic image obtained by photographing the whole body of the image, and FIG. 4B is a diagram showing a sketch-like painting-like image obtained by converting the digital photographic image. The trace of running the pencil represented here is a general downward slanting left.

  FIG. 5A is a diagram showing a state in which the whole body image of the image of FIG. 4A is trimmed so as to leave the head and forefoot. When the result of trimming is a vertically long image, the image of the elephant with only the head and forefoot after trimming is converted into a sketch-like painting-like image as shown in FIG. 5 (b). As shown in FIG. 5 (c), the image is rotated 90 ° to the right or rotated 90 ° to the left as shown in FIG.

  In this case, when the image is converted into a sketch-like picture-like image and printed out, it is converted into a sketch-like picture-like image and printed out in the trimmed state shown in FIG. 5A. ) Is enlarged and printed out. That is, the trace of the pencil running is enlarged and greatly roughed, resulting in a rough brush sketch.

  In order to avoid such problems, before converting to a sketch-like painting-like image, enlarge the pixel inserted between the original pixels for enlargement while applying a complementary process to create a fine texture similar to that before enlargement. From this, a sketch-style painting-like image is converted to this image and printed out. Then, the trace of running the pencil becomes a sketch-like painting-like image with natural roughness.

  FIG. 6 (a) is a diagram showing an image obtained by subjecting the enlarged image of FIG. 5 (c) to a normal-tone conversion process that is slanting to the left, and FIG. 6 (b) is a diagram after the conversion process. It is a figure which shows the state which printed and output the image according to the top and bottom with the top and bottom. As shown in FIG. 6 (b), the trace of running the pencil is in the reverse tone of lower right.

  As shown in FIG. 6 (b), an image in which the brush stroke has a negative tone in the lower right direction and an image in which the brush stroke shown in FIG. If they are mixed in the memory of the display printing apparatus 1, they are printed out and pasted on an album or the like and displayed as a list, or scroll display or thumbnails on the panel surface 12 of the display panel 11 of the image display printing apparatus 1 When displayed, it is unsightly and unnatural in various ways, such as when the stroke of a sketch-like painting-like image to be seen is downward or downward.

  Therefore, if an image converted into a sketch-like painting-like image is displayed or printed out with its top and bottom aligned with the top and bottom, if all the images are in a normal-tone slanting left-down stroke, the harmony will be achieved. Complete image database.

  When the top and bottom of the image displayed on the entire display screen is aligned with the top and bottom as shown in FIG. 4 (a), there is no problem in the normal-tone conversion process with the diagonally left-down as shown in FIG. 4 (b). . The problem arises when enlarging a crop that has been trimmed down.

  Although it is not particularly shown, when the image is divided by a cross line and trimmed to ¼ of the full screen, the trimmed and smaller wrinkles are horizontally long images. Even if the image is enlarged so that it is displayed on the entire screen, since the top and bottom of the image match the top and bottom, there is no problem because the image can be converted into a normal sketch-like painting-like image by the normal-to-left conversion processing.

  The problem as shown in FIG. 6B occurs when the wrinkles that have been trimmed and reduced as shown in FIG. 5A are vertically long images. Therefore, in this example, as shown in FIG. 3 (b), a reverse conversion process for expressing a trace of running a pencil diagonally downward is prepared.

  Then, when a vertically long image that has been trimmed to reduce wrinkles is rotated 90 ° to the left or right as shown in FIG. 5 (b) or 5 (c) and enlarged and displayed with pixel interpolation, the enlarged image is displayed. A conversion process in which the brush stroke is reversed is applied to the image.

  FIG. 7 (a) is a diagram obtained by performing a conversion process in which the brush stroke is reversed to the image rotated 90 ° rightward and enlarged to the full display as shown in FIG. 5 (b). FIG. 6 is a diagram of the converted image printed out with the top and bottom aligned with the top and bottom. In this way, if the image rotated 90 ° to the right is subjected to a reverse tone conversion process, the brush stroke will appear as a normal tone sketch image when printed out with the top and bottom aligned.

  Further, FIG. 8A is a diagram obtained by performing a conversion process in which the brush stroke is reversed on the image rotated 90 ° to the left as shown in FIG. b) is a diagram in which the converted image is printed out with the top and bottom aligned. In this way, even in the case of an image rotated 90 ° to the left, if reverse tone conversion processing is performed, the brush stroke will appear as a normal tone sketch image when printed up and down with the top and bottom aligned.

  The reason why the image display printing apparatus 1 of this example has the two conversion processing functions of the normal tone conversion processing function of FIG. 3A and the reverse tone conversion processing function shown in FIG. , As described above.

  FIG. 9 is a flowchart for explaining the operation of the process of converting a digital photographic image into a sketch-like painting-like image by the CPU 15 of the control device of the image display printing apparatus 1 having two types of conversion processing functions as described above.

  In FIG. 9, when processing is started, the CPU 15 first reads image data (step S1). In this process, if a memory card is inserted in the card slot, image data is read from the memory card. Alternatively, when a USB flash memory is inserted into the USB connector, image data is read from the USB flash memory.

  Subsequently, the CPU 15 displays “Is the vertical direction of the image aligned with the vertical direction of the screen?” On the panel surface 12 of the display panel 11 (step S2), and the user presses the “High” button or “No”. ”Button is pressed or an input from the user is awaited (step S3).

  If the “No” button is pressed, the top and bottom of the displayed image are aligned with the top and bottom of the screen (step S4). In this processing, for example, a “deformation” button of paint (image processing application) may be left to the user, or the top and bottom of the image may be automatically recognized and processed.

  Next, the CPU 15 displays "Do you want to trim" (step S5) and waits for an input from the user whether the "high" button or the "no" button has been pressed by the user (step S6).

  If it is determined in step S3 that the “Yes” button is pressed, the CPU 15 immediately proceeds to steps S5 and S6. If the “Yes” button is pressed in step S6, trimming processing is started (step S7).

  This trimming process is, for example, a trimming process as shown in FIG. 5A, and can generally be performed using an application of the trimming process. When the trimming is completed, the CPU 15 determines whether or not to immediately enlarge the trimmed image (step S8).

  In this process, when the image after trimming is not a vertically long image as shown in FIG. 5A, for example, when the image is divided by a cross line and trimmed to ¼ of the full screen, the trimmed image becomes smaller. Is a horizontally long image, and the top and bottom of the image are aligned with the top and bottom (Yes in S8), the trimming portion is enlarged and displayed as it is on the panel surface 12 of the display panel 11 (step S9).

  Subsequently, the CPU 15 performs a left-down brush stroke, that is, a normal sketch painting-like image conversion process on the image enlarged and displayed on the entire panel surface 12 (step S10). Then, the image data converted into the sketch painting style is stored in the memory (step S11).

  If it is determined in step S6 that the “NO” button has been pressed, the CPU 15 immediately proceeds to the processes in steps S10 and S11.

  If the image after trimming in step S8 is a vertically long image as shown in FIG. 5A, if the image is enlarged as it is, the top and bottom of the image will protrude from the screen (no discrimination in S8). The CPU 15 displays the characters “Please rotate 90 °” in an overlapping manner on the image, and waits until the user rotates the image 90 ° to the left or right (No in step S13).

  When the CPU 15 determines that the image has been rotated by 90 ° (Yes in S13), the CPU 15 enlarges and displays the rotated image on the size of the panel surface 12 of the display panel 11 (step S14). In addition, the above rotation. As long as the angle is 90 °, the rotation may be in either the left or right direction.

  Subsequently, as shown in FIG. 7 (a) or FIG. 8 (a), the CPU 15 performs an image conversion process in which the brush moves downward to the right, that is, an inverse sketch painting-like image on the enlarged image. (Step S15). Then, the process proceeds to step S11, and the image data converted into the sketch painting style is stored in the memory.

  Note that the processing in steps S1 to S15 is performed on the read image data for the number of image data desired by the user.

  When the conversion of the sketch painting style and the saving of the converted image in the memory are all completed, the CPU 15 displays “Do you want to display it?” On the CPU 15 and the panel surface 12 of the display panel 11 (step S16), and the user The “high” button or the “no” button is pressed or an input from the user is awaited (step S17).

  When the “Yes” button is pressed in the determination in step S17, the CPU 15 displays the image stored in the memory in step S11 as a scroll display or thumbnail image by aligning the top and bottom of the image with the top and bottom of the panel surface 12. A list is displayed (step S18).

  Whether the display is a scroll display or a list display of thumbnail images is determined by a user operating a tool button on the screen.

  Following the above, the CPU 15 determines whether or not there is a display end instruction input from the user (step S19). If there is no display end instruction input (No at S19), the process returns to step S18 to continue scroll display or thumbnail image list display.

  On the other hand, when there is a display end instruction input in the determination in step S19 (Yes in determination in S19), the CPU 15 subsequently displays “Do you want to print?” On the panel surface 12 of the display panel 11. (Step S20), whether the “high” button or the “No” button has been pressed by the user or waits for an input from the user (Step S21).

  If it is determined in step S17 that the “NO” button has been pressed, the CPU 15 immediately proceeds to the processes in steps S20 and S21. If it is determined in step S21 that the “Yes” button has been pressed, printing of the designated image is executed (step S22), and the process ends. If it is determined in step S21 that the “No” button has been pressed, the processing is immediately terminated.

  in this way. According to the image display printing apparatus 1 of this example, the normal sketch style painting processing conversion function of FIG. 3A and the inverse sketch style painting conversion function of FIG. Two conversion processing functions are provided.

  Therefore, when the read digital photograph image data is converted into a sketch-like painting-like image as it is, as well as the trimmed image as it is, when the top and bottom of the image are viewed on the top and bottom, FIG. As shown in FIG. 7 (b) or FIG. 8 (b), all of them are normal sketch-style painting-like images, so it is possible to create a database of sketch-style painting-like images that are harmonized in appearance.

  3 (a), (b) to FIG. 8 (a), (b) are all described as conversion into a black and white sketch-like picture-like image, the image display printing apparatus of this example 1 has a built-in full-color inkjet printing mechanism.

  Therefore, if the read digital photo image is full color, it can be converted into a sketch-like painting-like image drawn with a stroke of a colored pencil slanting to the left, like a sketch-like painting-like image drawn using a colored pencil. it can.
