Abstract

<P>PROBLEM TO BE SOLVED: To reduce the feeling of oddness, brought about when images accompanying animation effects are displayed. <P>SOLUTION: A mixture image, in which pixels corresponding to an odd-number column field and pixels corresponding to an even-numbered column field are mixed, is generated for a current image and a next display image (S200). A video chip is set into an odd-even identical mode, while the mixture image of the current display is written to a VRAM (S210). The mixed images are used to generate images in frames for a cross-fade effect and written to the VRAM, and this procedure is repeated (S220 to S260). After the image of the final frame (a mixed image of the next display image) is written to the VRAM, the video chip is set in a normal mode and the original image of the next display image is written in the VRAM (S270). By using the mixture images in the odd-even identical mode, pixels corresponding to the even-numbered column field of the original image are displayed as mixed, which reduces the feeling oddness brought on changing modes. <P>COPYRIGHT: (C)2006,JPO&NCIPI

These units and connectors are connected to the main control unit 32 via buses and signal lines.

  The main control unit 32 develops an image file input from the PC card 15 via the card operation unit control unit 38 or an image file input from the peripheral device 17 via the host USB connector 48 according to the file format. A layout process is performed to create a print image, and this print image is subjected to processes such as color conversion to CMYK and binarization, and is converted into data that can be printed by the print head 63 to execute printing. Printing is executed based on a printer control command and print data input from the PC 16 via the USB connector 50. The main control unit 32 not only performs processing related to the execution of printing, but also performs various operations such as designation of an image to be printed, setting of layout, setting of printing conditions, etc. on the screen display on the television receiver 12 and the light receiving unit 26. Various processes are also executed when an operation signal is input from the operation panel 25.

  The video chip 40 outputs the screen image written in the VRAM 42 to the television receiver 12 as an interlaced NTSC signal for displaying the screen image in two stages of an odd-numbered field and an even-numbered field, and the screen image of the VRAM 42 is directly used as an NTSC signal. A normal mode for outputting and an odd-numbered and even-numbered mode for outputting as an NTSC signal using only a screen image corresponding to an odd-numbered row field are provided. FIG. 3 is an explanatory diagram for conceptually explaining the normal mode and the odd-numbered even mode. As shown in the figure, in the normal mode, the screen image corresponding to the odd-numbered field is output as the NTSC signal of the odd-numbered field and the screen image corresponding to the even-numbered field is output as the NTSC signal of the even-numbered field.

When the optical signal is received by the light receiving unit 26, the card operation unit control unit 38 analyzes and codes the optical signal and passes it to the main control unit 32 as described above. The main control unit 32 executes each process based on the received code.

  Next, the operation of the printing apparatus 20 of the embodiment configured as described above, particularly the operation when performing a slide show display for sequentially displaying images stored in the PC card 15 or the like will be described. FIG. 5 is an explanatory diagram showing an example of an image list screen 100 displayed on the television receiver 12 after the printing apparatus 20 is turned on and performs a predetermined initial operation. The image list screen 100 is composed of a list display area 102 for displaying a list of images and an operation explanation area 104 for explaining button operations of the remote controller 90, as shown in the figure, and images read from the PC card 15 or the like. A thumbnail of the file is displayed in the list display area 102. When the slide show button 93 d of the remote controller 90 is pressed while the image list screen 100 is displayed, the slide control execution process illustrated in FIG. 6 is executed by the main control unit 32. Hereinafter, the slide show execution process will be described.

  In the slide show execution process, first, as shown in the figure, a process of displaying the image on which the focus frame is adjusted on the image list screen 100 on the television receiver 12 as the first image of the slide show is executed (step S100). This process is performed by reading the image file of the image with the focus frame adjusted from the PC card 15 or the like and writing it in the VRAM 42.

  Then, until the operator gives an instruction to end the slide show (for example, until the return button 93f of the remote controller 90 is pressed), the next display image to be displayed next among the images stored in the PC card 15 or the like is crossfade. The crossfade display process for displaying with an effect is repeatedly executed (steps S110 and S120). Here, the description of the slide show execution process is interrupted, and the cross fade display process illustrated in FIG. 7 will be described.

  In the crossfade display process, first, as shown in the figure, for each of the currently displayed image and the next displayed image, the pixels corresponding to the odd-numbered row field and the pixels corresponding to the even-numbered row field in the NTSC signal are obtained. A mixed mixed image is generated and stored in a predetermined area of the SDRAM 36 (step S200). FIG. 8 is an explanatory diagram for conceptually explaining the mixed image. As shown in the figure, the mixed image includes pixels corresponding to the upper odd row field and lower even rows for every other pixel in the row direction (in the example of FIG. 8, even-numbered pixels in the row direction). It is generated by replacing the pixel corresponding to the field. The next display image can be specified according to a predetermined image display order (for example, ascending order of image file names).

  Subsequently, a control signal is transmitted to the video chip 40 so as to be in the odd and even mode, and a mixed image of the current display image is written in the VRAM 42 (step S210). In the embodiment, the portion corresponding to the odd-numbered row field in the mixed image of the current display image is written in the region corresponding to the odd-numbered row field of the VRAM 42. Of course, since the screen image of the area corresponding to the even-numbered field of the VRAM 42 is ignored in the odd-numbered even mode, the entire mixed image may be written in the VRAM 42. FIG. 9 is an explanatory diagram showing a state of a screen image written in the VRAM 42 and an image displayed on the television receiver 12 when the video chip 40 that has received the control signal switches from the normal mode to the odd-numbered even-numbered mode. As shown in the figure, when the video chip 40 is switched to the odd-even mode, the mixed image is written into the VRAM 42, and a part of the pixels corresponding to the even-line field of the original image (the image before the pixel replacement) is written. The display is replaced with the pixels in the odd-numbered field. Here, in comparison with a case where the video chip 40 is switched from the normal mode to the odd-numbered even-numbered same mode while the original image is displayed, in this case, the pixels corresponding to the even-numbered field of the original image are odd-numbered and even-numbered. For example, in the case of an image having a gradation in the vertical direction, it may appear as if the entire image has been slid in the vertical direction when the mode is switched to the odd and even mode ( (See FIG. 10). On the other hand, in the printing apparatus 20 of the embodiment, when switching to the odd-numbered even mode, the pixels corresponding to the even-numbered row field of the original image are also mixed and displayed, so that it is possible to reduce the sense of incongruity that occurs when switching. It is.

  Subsequently, an image of each frame of the crossfade effect is generated in the VRAM 42 using the mixed image of the current display image and the mixed image of the next display image so that the next display image is displayed with the crossfade effect. The writing process is repeatedly executed (steps S220 to S260). Specifically, each frame is synthesized by synthesizing the portion corresponding to the odd-numbered row field of each mixed image based on the synthesis ratio of the current display image and the next display image in each frame having a predetermined crossfade effect. This image is generated, and the generated image of each frame is written in an area corresponding to the odd-numbered row field of the VRAM 42. FIG. 11 is an explanatory diagram showing an example of the composition ratio of the current display image and the next display image in each frame. As shown in the figure, the composition ratio of the next display image increases as the composition ratio of the current display image decreases, and the composition ratio of the next display image is 100% in the final frame. It should be noted that the process of displaying an image with such a crossfade effect is a general process and does not form the core of the present invention, and therefore will not be described in further detail.

  When the image of the last frame of the crossfade effect (that is, the mixed image of the next display image) is written in the VRAM 42, a control signal is transmitted to the video chip 40 so as to be in the normal mode, and the source of the next display image Are written in the VRAM 42 (step S270), and the crossfade display processing is terminated. FIG. 12 is an explanatory diagram illustrating a state of a screen image written in the VRAM 42 and an image displayed on the television receiver 12 when the video chip 40 is switched from the odd-numbered even mode to the normal mode. As shown in the figure, similarly to the case of switching from the normal mode illustrated in FIG. 9 to the odd-numbered even mode, the pixels corresponding to the even-numbered row field of the original image are also mixed and displayed in the odd-numbered even-mode, It is possible to reduce the uncomfortable feeling that occurs when the original image is displayed by switching to the normal mode.

  When such a crossfade display process is repeatedly executed and the operator gives an instruction to end the slide show, the slide show execution process returns to the display of the image list screen 100 (step S130), and the process ends.

  According to the printing apparatus 20 of the embodiment described above, when the slide show is executed, the video chip 40 is switched to the odd-numbered and even-mode, and the cross image using the mixed image of the current display image and the mixed image of the next display image is used. By repeatedly executing the process of generating the image of each frame of the fade effect and writing it to the VRAM 42, the next display image can be displayed with the crossfade effect. At this time, since the image corresponding to the odd-numbered field of each mixed image is synthesized to generate the image of each frame, it is possible to further reduce the processing load on the image display with the crossfade effect. In addition, when switching the video chip 40 from the normal mode to the odd-numbered even-mode, or from the odd-numbered even-mode to the normal mode, the odd-numbered even-mode side uses the mixed image so that the even-numbered field of the original image is displayed. Since the corresponding pixels are also displayed in a mixed manner, it is possible to reduce the sense of incongruity that occurs when switching.

  Here, in the printing apparatus 20 according to the embodiment, the VRAM 42 corresponds to the screen image storage unit, the video chip 40 corresponds to the screen image output unit, the PC card 15 corresponds to the image storage unit, and the processes in steps S200 to S260 are performed. The main control unit 32 that executes the process corresponds to an image animation display unit, and the main control unit 32 that executes the process of step S270 corresponds to a post-process execution unit.

  In the printing apparatus 20 according to the embodiment, the mixed image is generated by switching pixels corresponding to the upper odd-numbered row field and pixels corresponding to the lower even-numbered row field for every other pixel in the row direction. However, the pixel corresponding to the odd-numbered row field and the pixel corresponding to the even-numbered row field may be interchanged, and it is not always necessary to target every other pixel in the row direction. Moreover, what is necessary is just to mix the pixel corresponding to an odd-numbered row field and the pixel corresponding to an even-numbered row field, and is not restricted to the mixing by replacement of a pixel. For example, the pixel value corresponding to the odd row field and the pixel corresponding to the even row field may be mixed by calculating the average value of the pixel values of the pixels in the even row field and the pixels in the odd row field.

  In the printing apparatus 20 of the embodiment, when the video chip 40 is switched from the normal mode to the odd-numbered even-numbered mode, or when the video chip 40 is switched from the odd-numbered even-numbered mode to the normal mode, the mixed image is used on the odd-numbered even-numbered mode side. Pixels corresponding to the even-numbered field of the image are mixed and displayed, and the original image is displayed on the normal mode side, but the mixed image display in the odd-numbered even mode and the original image display in the normal mode Between them, display of the mixed image in the normal mode may be interposed (see FIG. 13). By so doing, it is possible to further reduce the sense of discomfort that occurs during switching.

  In the printing apparatus 20 of the embodiment, a mixed image is generated for each of the current display image and the next display image and stored in a predetermined area of the SDRAM 36. However, since the mixed image may be used, the mixed image is not necessarily stored in the SDRAM 36. There is no need to remember. For example, the SDRAM 36 may store the original image, and the stored original image may be used while being converted into a mixed image. Further, even if a mixed image is not generated for each of the current display image and the next display image, the original image may be used for the current display image.

  In the printing apparatus 20 of the embodiment, when the slide show is executed, the next display image is displayed with the cross fade effect. However, it is needless to say that the timing may be other than the execution of the slide show. In addition, an image may be displayed with an animation effect other than the crossfade effect. In this case, the image of each frame of the animation effect is generated using the mixed image of the images to be displayed in the odd and even mode, and is written in the area corresponding to the odd row field of the VRAM 42, and the image of the last frame (the image to be displayed) When the mixed image is written in the VRAM 42, the normal mode is set and the original image is written in the VRAM 42.

  In the printing apparatus 20 of the embodiment, the video chip 40 outputs the screen image corresponding to the odd-numbered field in the odd-numbered even mode as the NTSC signal of both the odd-numbered field and the even-numbered field. Of course, the screen image corresponding to the above may be output as NTSC signals for both the odd-numbered field and the even-numbered field.

  In the printing apparatus 20 of the embodiment, the outer shape of the printing apparatus main body 22 is 20 cm or less in height, 60 cm or less in width, and 60 cm or less in depth, but is not limited to such an outer shape, and has any shape. It doesn't matter.

  In the printing apparatus 20 of the embodiment, one of the side surfaces is the front surface 23, and the ink cartridge is attached or detached from the front surface 23, or is supplied and discharged. However, the ink cartridge is attached or detached from another portion, There is no problem even when paper feeding / discharging is performed from other parts.
