Note that the LCD panels 27R, 27G, and 27B, the lamp 28, the combining prism 29, the projection lens 30, and the screen 31 are collectively referred to as a display device 34. The control unit 25 has a built-in register 25a for storing various control data (printing process, outline color), and controls the entire apparatus. In particular, in the present embodiment, the information input unit 23 Is input, and a process such as outputting a control signal to the image processing unit 22 is performed. In order to facilitate understanding of the present invention, the block for processing the voice function is not shown in FIG.

  The TV broadcast receiver 11 of the television receiver 1 may be either for analog broadcast or digital broadcast, but if it is for digital broadcast, it includes a tuner, a demultiplexer, and a video signal processing circuit ( In either case, the controller 25 outputs a channel selection signal to the tuner, so that a channel corresponding to the channel selection signal is set by the tuner. The antenna 10 includes a frequency converter, receives a digital broadcast signal sent from, for example, CS (Communication Satellite), and outputs the frequency-converted signal to the tuner. The tuner includes a demodulation circuit, a deinterleave circuit, an error correction circuit, and the like, and performs a process of extracting a signal having a specific frequency from a high frequency digital modulation signal including video / audio data. That is, a process of selecting one from a plurality of transponders for digital broadcasting is performed. The demultiplexer (DEMUX) separates the transport stream into, for example, an MPEG2 (Moving Picture Experts Group2) video stream, an audio stream, and a PSI / SI (Program Specific Information / Service Information). Output to the signal processing circuit. The video signal processing circuit has a built-in video decoder and the like, decodes the input variable length code to obtain a quantization coefficient and a motion vector, performs inverse DCT transform, motion compensation control based on the motion vector, etc. The video signal (digital format RGB or YUV video signal) corresponding to the channel selection signal of the tuner is output to the image processing unit 22.

  When a video signal corresponding to the terminal is input from any one of the composite video signal terminal 12, the S terminal 13, the D terminal 14, and the analog YUV signal terminal 15, the video signal passes through the A / V switch 16. The video signal is decoded by the video decoder 17 and the decoded video signal (digital format RGB video signal / YUV video signal) is output to the image processing unit 22.

  When a memory card (not shown) is inserted into the memory card slot 18, the memory card controller 19 reads the video signal stored in the memory card and outputs it to the decoder (JPEG decoder / MPEG decoder) 20. The decoder 20 decodes the video signal and outputs it to the image processing unit 22 (digital format RGB video signal / YUV video signal).

  When the image processing unit 22 takes in the video signal from the TV broadcast receiving unit 11, the video decoder 17, or the decoder 20, the image processing unit 22 resizes the video signal in accordance with the resolution of the subsequent liquid crystal panels 27R, 27G, and 27B.

The LCD driver -26 D / A converts the video signal of the frame image to drive the subsequent liquid crystal panels 27R, 27G, 27B, draws images on the liquid crystal panels 27R, 27G, 27B, and draws the drawn images. The light of the lamp 28 modulated by the above is synthesized by the synthesis prism 29 and projected onto the screen 31 by the projection lens 30. In this way, the video signal is displayed on the screen 31 from the TV broadcast receiver 11, the video decoder 17 or the decoder 20.

  When the image processing unit 22 receives a print command, the image processing unit 22 outputs video data (digital RGB data) to the printer processing unit 32. The printer processing unit 32 converts the video data (digital RGB data) into CMYK data (raster data). The converted video data is output to the printer 33, and the printer 33 performs a printing process based on the converted video data.

  FIG. 2 is a front view of the remote controller 40 that constitutes a part of the information input unit 23. Various keys are attached to the remote controller 40. As shown in the figure, for example, a numerical key 41, channel increase / decrease keys 42, 43, volume increase / decrease keys 44, 45, direction key 46, enter key 47, Various keys such as a registration key 48, a coloring key 49, a save key 50, and an edit key 51 are provided. The registration (capture) key 48 is a key for outputting an operation signal for generating a still image (capture image) from an image displayed on the display device 34. The coloring key 49 is a key for outputting an operation signal for generating a contour line image (coloring sketch) using a still image as an original image. The save key 50 is a key for outputting an operation signal for causing the hard disk 21 to store the video data of the original image and the contour line image. The edit key 51 is a key for reading out video data stored in the hard disk 21 and outputting an operation signal for causing the display device 34 to display the original image and / or the contour line image. For these operation keys 41 to 51, the operation signal is taken into the control unit 25, and various processes corresponding to the operation signal are performed.

  3 and 4 are flowcharts showing the processing of the image processing unit 22 and the printer processing unit 32. This processing is repeated at predetermined time intervals. In the television receiver of FIG. 1, the image processing unit 22 takes in a video signal from, for example, a TV broadcast receiving unit, performs the above-described signal processing, and outputs it to the LCD driver 26. , 27B, and the image is projected onto the screen 31. In this state, the image processing unit 22 determines whether or not the registration key 48 has been pressed based on an operation signal from the registration key 48 supplied via the control unit 25 (S11). If the image processing unit 22 determines that the registration key 48 has been pressed, the image processing unit 22 next determines whether or not the video signal of the currently displayed image is an interlaced video signal (S12). If it is, the video signal of the currently displayed image is IP converted (S13), a still image is generated based on the IP converted video signal, and this is used as the original image (S14). ). In other words, if it is an interlaced video signal, the odd-field video signal and the even-field video signal are each captured and combined to generate a non-interlaced (progressive) video signal. The image related to the signal is the original image.

  Next, the image processing unit 22 determines whether or not the coloring key 49 is pressed based on an operation signal from the coloring key 49 supplied via the control unit 25 (S15). If it is determined that the coloring key 49 has been pressed, the image processing unit 22 performs a process of extracting the outline of the original image (S16). The process of extracting the contour line is performed, for example, by detecting an edge of a still image by performing an edge detection process using a filter such as an 8-direction Laplacian filter.

  The image processing unit 22 determines whether the save key 50 has been pressed based on the operation signal of the save key 50 supplied via the control unit 25 (S17). If it is determined that the save key 50 has been pressed, the image processing unit 22 performs a save process (S18). For example, video data of an original image and a contour image corresponding to the original image are stored in the hard disk 21 in a file format such as JPEG. Next, the image processing unit 22 refers to the register 25a of the control unit 25 to determine whether or not a print instruction is set (S19). If the print instruction is set, the register of the control unit 25 is determined. It is determined whether or not the color of the contour line is set with reference to 25a (S20). If the color is set, the color for changing the color of the contour line based on the set color A decision process is performed (S21). Then, the image processing unit 22 refers to the register 25a of the control unit 25 to determine whether or not to print the original image (S22). In this example, it is assumed that the original image is printed on the back side of the printing paper. The original image is reversed left and right so that it matches the contour image of the surface, the original image is positioned, and the contour image and the video data (digital RGB data) of the original image are transmitted to the printer processing unit 32. (S23). In the above process, the image processing unit 22 develops the contour line image and the video data of the original image in the frame memory 22a and outputs them to the LCD driver 26 to display the contour line image and the original image on the display device 34. To display. When displaying an image, without displaying the contour line image and the original image at the same time, only one of them is displayed on the display device 34, and the other video data is stored in the memory 22b. The other image may be displayed on the display device 34 by operating an appropriate key of the remote controller 40.

  The printer processing unit 32 converts the received video data (digital RGB data) into YMCK data, and raster data for enabling printing by the printer 33 including data such as a print start position and paper feed amount information. It is created (S24), and the raster data is transmitted to the printer 33 (S25). The printer 33 performs a printing process based on the given data. In this example, a contour image (coloring sketch) is printed on the front surface, and an original image is printed on the back surface.

  FIG. 5 shows an outline image (coloring sketch) on the front side printed by the printer 33, and the original image is printed on the back side (not shown).

  In the above description, the example in which the contour image is generated from the video signal from the TV broadcast receiving unit 11 has been described. However, the composite video signal terminal 12, the S terminal 13, the D terminal 14, or the analog YUV signal terminal 15 is described. Even if an external device is connected to capture the video signal, or a memory card (not shown) is inserted into the memory card slot 18 and the image file stored in the memory card is captured, the contour line is similarly obtained. Images and original images can be generated and printed. In that case, the image file may be either a moving image or a still image.

  Further, in this embodiment, every time the save key 50 in FIG. 2 is pressed, the video data of the original image and the video data of the contour image are stored in the hard disk 21. Therefore, for example, when the user presses the edit key 51, the image processing unit 22 reads the video data of the original image stored in the hard disk 21 and displays it on the display device 34, and shift key 46 and enter key 47 of the remote controller 40. When an original image is selected by operating, the video data of the contour image corresponding to the selected original image can be read, output to the printer processing unit 32, and printed by the printer 33. Alternatively, when the image data of the contour image on the hard disk 21 is read out and displayed on the display device 34 and the contour key image is selected by operating the direction key 46 and the enter key 47 of the remote controller 40, the selected contour image is displayed. The video data of the line image can be output to the printer processing unit 32 and printed by the printer 33.

  As described above, in the first embodiment, it is possible to easily create a sketch for a coloring scene for a favorite scene while watching a favorite animation program (content such as TV broadcast, DVD, video, etc.). In the case of an interlaced video signal, both the odd and even fields are captured and combined to generate a noninterlaced video signal, and the contour detection process is performed using the image of the noninterlaced video signal as the original image. This makes it possible to create a more beautiful background picture for coloring. In addition, the original image can be printed so that the outline image (background image) and the original image overlap when the original image is printed with the original image aligned to the back side and viewed through the watermark. You can play with coloring.

  3 and 4 is performed every time the registration key 48 of the remote controller 40 is pressed, a plurality of original images and contour images can be stored in the hard disk 21. Therefore, as described above, a plurality of original images and outline images can be printed together on a single sheet, and various scenes can be played with a single sheet of paper. Further, when printing is performed using only the contour line, for example, a black contour line is configured in the default setting, but by changing the setting, the contour line can be configured in a light color, for example. In such a case, the user can trace the light-colored outline with a pen, and can provide not only coloring but also the pleasure of making a sketch.

The processing of the flowchart may be started, and all of the processing (S12 to S14, S16, S18, and S19) of the flowchart of FIG. 3 may be performed.

  In the first embodiment, the example in which the contour line of the original image is extracted and the contour image is printed has been described. However, the contour line is synthesized with the video data of the contour image and the video data of the original image. May be generated and printed. By doing so, it is possible to play coloring with the original image as a sample. When the original image is printed on another paper, the print position is matched with the print position of the contour image, and the position of the image is matched when the two printed sheets are overlapped.

  Further, by extracting a contour line extracted from the original image from the original image, it is possible to generate and print an image having a color but without a contour line. It is possible to draw a pen with a pen and complete a single image, providing a way of playing that is different from the usual coloring book. By operating 40 appropriate keys, the image processing unit 22 can change the color to an arbitrary color.

  In the first embodiment, the example in which the printer 33 is built in has been described. However, the printer 33 may be externally connected and connected by, for example, a USB cable. In addition, the example in which the television receiver has a function of generating video data of the background image of the coloring book has been described.
