FIG. 3 is a flowchart illustrating a capture process for generating a still image from an image recorded on the hard disk drive 10 by the CPU 6 executing the control program.
[0056]
In step S11, the control program displays an image while recording the image on the hard disk drive 10.
[0057]
More specifically, the video A / D converter 3 applies A / D conversion to the image signal supplied from the tuner 1 to generate image data, and converts the image data into the MPEG video encoder 5 and It is supplied to the graphic chip 15. The control program causes the MPEG video encoder 5 to encode image data and supply the encoded image data to the multiplexer 9.

[0060]
The control program causes the graphic chip 15 to supply the image data supplied from the video A / D converter 3 to the video D / A converter 16 as it is. The video D / A converter 16 converts the image data supplied from the graphic chip 15 into an analog image signal, outputs an analog image signal, and displays the image on a display (not shown).
[0061]
In step S12, the control program executes a capture button on the remote controller or an input unit based on a signal supplied from the remote controller light receiving unit 20 or a signal supplied from an input unit (not shown) having a switch or a touch panel. The signal corresponding to the operation of the capture button is acquired. The signal acquired in the process of step S12 is one of a signal indicating that the capture button has been pressed and a signal indicating that the capture button has not been pressed.
[0062]
In step S13, the control program determines whether or not the capture button has been pressed based on the signal acquired in the process of step S12. If it is determined that the capture button has not been pressed, the process returns to step S12. The determination process is repeated until the capture button is pressed.
[0063]
If it is determined in step S13 that the capture button has been pressed, the process proceeds to step S14, and the control program acquires the time on the displayed image at which the capture button was pressed. The control program records the obtained time in the RAM 7 or the hard disk drive 10.
[0064]
The time on the image corresponding to the recorded image is obtained based on the time supplied from a real-time clock (not shown). The time on the image corresponding to the recorded image is obtained, for example, from the time data stored in the header of the MPEG data.
[0065]
In step S15, the control program captures an image corresponding to the time acquired in the processing in step S14. That is, the control program causes the graphic chip 15 to store the frame data of the image at the time acquired in the process of step S14 in the memory inside the graphic chip 15.
[0066]
In step S16, the control program displays the image captured in the processing in step S15.
[0067]
That is, the control program causes the graphic chip 15 to supply the frame data of the image stored in the internal memory to the video D / A converter 16. The video D / A converter 16 converts the frame data of the image supplied from the graphic chip 15 into an analog image signal, outputs an analog image signal, and displays the image on a display (not shown). Let it. Therefore, one frame of the image at the time when the capture button is pressed, that is, a still image, is displayed on the display.
[0068]
In step S17, the control program determines whether or not to determine a still image to be displayed based on a signal supplied from the remote controller light receiving unit 20 or a signal supplied from an input unit (not shown). If it is determined in step S17 that the displayed still image is determined, the process proceeds to step S18, where the control program saves the still image, returns to step S12, and repeats the process.
[0069]
That is, the control program causes the graphic chip 15 to supply the frame data of the image stored in the internal memory to the JPEG encoder 18. The control program causes the JPEG encoder 18 to encode the image frame data by a still image encoding method such as JPEG to generate still image data. The control program records the data of the generated still image in a predetermined area of the hard disk drive 10.
[0070]
For example, the control program assigns a name to the first captured still image as Image 1 and saves the still image in a predetermined folder of the hard disk drive 10. The control program assigns a name to the second captured still image as Image 2 and saves it in a predetermined folder of the hard disk drive 10.
[0071]
As described above, the control program assigns a predetermined name to the captured still image and saves it in a predetermined folder of the hard disk drive 10.
[0072]
If it is determined in step S17 that the still image to be displayed is not determined, the process proceeds to step S19, in which the process of adjusting the time of the image to be captured is performed, and the process returns to step S15 to perform the capture process and the image Repeat the display process.
[0073]
The capture processing ends when the image display processing in step S11 ends.
[0074]
Note that the already recorded image may be displayed, and the displayed image may be captured.
[0075]
FIG. 4 is a flowchart illustrating details of the process of adjusting the time of the captured image in step S19.
[0076]
In step S31, the control program responds to operation of a button on the remote controller or a button of the input unit based on a signal supplied from the remote controller light receiving unit 20 or a signal supplied from an input unit (not shown). Get the signal.
[0077]
In step S32, the control program obtains the time during which the button is continuously pressed based on the signal obtained in the process of step S31.
[0078]
In step S33, the control program obtains the time of the image corresponding to the pressed button and the time of continuous pressing obtained in the process of step S32, and the process ends.
[0079]
In this manner, the time of the image corresponding to the pressed button and the time of the image corresponding to the continuously pressed time is calculated, and the image is captured based on the calculated time, Is displayed.
[0080]
By the processing of step S15 and step S16 in FIG. 3, an image corresponding to the calculated time of the image is captured and displayed.
[0081]
When the image corresponding to the calculated time of the image is captured by the processing of steps S15 and S16, the control program causes the hard disk drive 10 to read out the image data and the MPEG video decoder 13 to read out the image data. The data of the decoded image is decoded, and an image corresponding to the calculated time of the image is captured and displayed based on the decoded image data.
[0082]
Next, a specific example of the process in step S33 will be described.
[0083]
For example, as shown in FIG. 5, when a predetermined right button of the remote controller is pressed for one second, the control program obtains a time 0.5 seconds ahead in the process of step S33. In this case, in the processing of steps S15 and S16, an image 0.5 seconds ahead is captured and displayed.
[0084]
Further, in the process of step S33, when the right button is pressed for 2 seconds in the process of step S33, the control program sets the time when the right button is pressed for 1 second to 0.5 seconds based on the current time. The previous time is obtained, and when the right button is pressed for another 1 second, the time 1.0 second ahead is obtained by a calculation of 0.5 × 2 based on the time 0.5 second ahead. Therefore, when the right button is pressed for 2 seconds, in the processing of steps S15 and S16, an image 0.5 seconds ahead is captured and displayed based on the current time, and then 1. The image 5 seconds ahead is captured and displayed.
[0085]
Further, in the process of step S33, when the right button is pressed for 3 seconds, the control program sets the time when the right button is pressed for 1 second, based on the current time, based on the current time. The time 5 seconds ahead is obtained, and at the time when the right button is further pressed for 1 second, the time 1.0 seconds ahead is further calculated by 0.5 × 2 based on the time 0.5 seconds ahead. When the button on the right side is further pressed for one second, a time 2.0 seconds ahead is obtained by a 1.0 × 2 calculation based on the time 1.5 seconds ahead. Therefore, when the right button is pressed for 3 seconds, in the processing of step S15 and step S16, an image 0.5 seconds ahead is captured and displayed based on the current time, and then 1. An image 5 seconds ahead is captured and displayed, and an image 3.5 seconds ahead is captured and displayed.
[0086]
On the other hand, when the predetermined left button of the remote controller corresponding to the right button is pressed for one second, the control program obtains a time 0.5 seconds before in the process of step S33. In this case, in the processing of step S15 and step S16, the image 0.5 seconds before is captured and displayed.
[0087]
In addition, in the process of step S33, when the left button is pressed for 2 seconds in the process of step S33, the control program sets the time when the left button is pressed for 1 second to 0.5 seconds based on the current time. The previous time is obtained, and when the left button is further pressed for one second, the time 1.0 second earlier is obtained by a calculation of 0.5 × 2 based on the time 0.5 second earlier. Therefore, when the left button is pressed for 2 seconds, in the processing of steps S15 and S16, an image 0.5 seconds ago is captured and displayed, based on the current time, and then 1. The image 5 seconds ago is captured and displayed.
[0088]
Further, in the process of step S33, when the left button is pressed for 3 seconds, the control program sets the time when the left button is pressed for 1 second, based on the current time. The time before 5 seconds is obtained, and at the time when the left button is further pressed for 1 second, the time before 1.0 second is further calculated by the calculation of 0.5 × 2 based on the time 0.5 second before. When the left button is pressed for one second, the time before 2.0 seconds is obtained by the calculation of 1.0 × 2 based on the time 1.5 seconds before. Therefore, when the left button is pressed for 3 seconds, in the processing of step S15 and step S16, the image 0.5 second before is captured and displayed based on the current time, and then 1. The image 5 seconds ago is captured and displayed, and the image 3.5 seconds ago is captured and displayed.
[0089]
FIG. 6 is a diagram illustrating the relationship between the time during which the button is continuously pressed and the time of the image to be added.
[0090]
In FIG. 6, a plus time indicates a time before (after) the present time, and a minus time indicates a time before (previous) from the present time.
[0091]
When the right button is kept pressed for one second, +0.5 seconds is added to the time of the captured image, and the image 0.5 seconds after the current time is captured and displayed.
[0092]
If the right button is kept pressed for 2 seconds, +0.5 seconds is added to the time of the captured image when the right button is kept pressed for 1 second, and the image 0.5 seconds after the current time Is captured and displayed, and when the right button is kept pressed for 2 seconds, an additional +1.0 second is added to the time of the captured image, and the time of the original image is increased by 1.5. The image after a second is captured and displayed.
[0093]
When the right button is kept pressed for 3 seconds, when the right button is kept pressed for 1 second, +0.5 seconds is added to the time of the captured image, and the image 0.5 seconds after the present time Is captured and displayed, and when the right button is kept pressed for 2 seconds, an additional +1.0 second is added to the time of the captured image, and the time of the original image is increased by 1.5. The image after a second is captured and displayed. When the right button is kept pressed for 3 seconds, +2.0 seconds are added to the time of the captured image, and the image 3.5 seconds after the time of the original image is captured. ,Is displayed.
[0094]
When the left button is pressed for one second, −0.5 seconds is added to the time of the captured image, and the image 0.5 seconds before the current time is captured and displayed.
[0095]
When the left button is kept pressed for 2 seconds, at the point when the left button is kept pressed for 1 second, -0.5 seconds is added to the time of the captured image, and 0.5 seconds before the current time is added. When the image is captured and displayed, and the left button is held down for two seconds, an additional -1.0 second is added to the time of the captured image, and one time is added to the time of the original image. The image 5 seconds ago is captured and displayed.
[0096]
If the left button is kept pressed for 3 seconds, at the point when the left button is kept pressed for 1 second, -0.5 seconds is added to the time of the captured image, and 0.5 seconds before the current time is added. When the image is captured and displayed, and the left button is held down for two seconds, an additional -1.0 second is added to the time of the captured image, and one time is added to the time of the original image. The image 5 seconds ago is captured and displayed. When the left button is kept pressed for 3 seconds, an additional -2.0 seconds is added to the time of the captured image, and an image 3.5 seconds before the time of the original image is captured. Is displayed.
[0097]
As described above, when the right button or the left button is continuously pressed for a while, the time of the captured image is adjusted in accordance with the time when the button is kept pressed, and the time of the time corresponding to the time when the button is continuously pressed is adjusted. The image is captured and displayed.
[0098]
The maximum value of the absolute value of the time to be added when the button is continuously pressed is determined in advance. For example, the operation is restricted by setting the length of one tenth of the length of the image as the maximum value of the absolute value of the time to be added.
[0099]
Here, one second is described as a unit for pressing the button. However, the time is not limited to one second. For example, a time that the user can smoothly operate such as 0.5 second or 0.2 second is set. It can be a unit.
[0100]
As described above, by adjusting the time of a captured image, fine adjustment of time and rough adjustment of time can be realized in a well-balanced manner. That is, rough time can be adjusted more quickly, and finer and more subtle time can be adjusted.
[0101]
More simply, when the right button is pressed, an image at a time earlier by 1/100 of the length of the recorded image is captured and displayed, and when the left button is pressed, It is also possible to capture and display an image at a time earlier by one hundredth of the length of the recorded image.
[0102]
FIG. 7 is a flowchart illustrating a process of setting a still image corresponding to a genre of a program by the CPU 6 that executes the control program.
[0103]
In step S51, the control program displays the captured still image.

That is, as shown in FIG. 8, the control program causes the hard disk drive 10 to read the captured still image data and supply the read still image data to the JPEG decoder 19. The control program causes the JPEG decoder 19 to decode the still image data and supply the decoded still image data to the graphic chip 15. The control program causes the graphic chip 15 to supply the decoded still image data supplied from the JPEG decoder 19 to the video D / A converter 16 as it is. The video D / A converter 16 converts the still image data into a still image signal, outputs the signal to a display, and displays the still image on the display.
[0105]
Finally, as shown in FIG. 9, the control program causes the captured still image to be displayed on, for example, an EPG thumbnail selection screen.
[0106]
The user selects a genre and a still image from the EPG thumbnail selection screen, and the selected still image is registered as a still image representing the genre.
[0107]
That is, in step S52, the control program determines whether or not a genre has been selected based on a signal from the remote controller light receiving unit 20 or the input unit. Until the selection is made, the processing of the determination in step S52 is repeated.
[0108]
Here, the genre of the image corresponds to, for example, news, a movie, baseball, weather, soccer, or a document, and the genre of the image indicates a feature of the image corresponding to the classification of the image. In the present invention, the genre of a content refers to a feature of the content corresponding to the classification of the content.
[0109]
More specifically, for example, the control program moves a cursor for selecting a genre when a predetermined right or left button of the remote controller is pressed on the EPG thumbnail selection screen shown in FIG.
[0110]
The control program changes the genre selected by the cursor when a predetermined upper or lower button of the remote controller is pressed on the EPG thumbnail selection screen. For example, when the genre selected by the cursor is baseball, the control program changes the genre selected by the cursor to soccer when the upper button of the remote controller is pressed. For example, when the genre selected by the cursor is soccer, the control program changes the genre selected by the cursor to a movie when the upper button of the remote controller is pressed.
[0111]
In step S52, the control program determines that the genre selected by the cursor has been selected when a predetermined determination button of the remote controller is pressed.
[0112]
When it is determined in step S52 that the genre has been selected, the process proceeds to step S53, and the control program determines whether a still image has been selected based on a signal from the remote controller light receiving unit 20 or the input unit, and determines whether a still image has been selected. If it is determined that an image has not been selected, the processing of the determination in step S53 is repeated until a still image is selected.
[0113]
If it is determined in step S53 that the still image has been selected, the process proceeds to step S54, and the control program determines that the still image has been selected in the process of step S53 corresponding to the genre determined to be selected in the process of step S52. The set still image is set, and the process ends.
[0114]
More specifically, for example, the control program moves a cursor for selecting a still image when a predetermined right or left button of the remote controller is pressed on the EPG thumbnail selection screen shown in FIG.
[0115]
The control program changes the still image selected by the cursor when a predetermined upper or lower button of the remote controller is pressed on the EPG thumbnail selection screen. For example, if the still image selected by the cursor is the first captured image 1, the control program causes the still image selected by the cursor to be second when the upper button of the remote controller is pressed. Change to captured image 2. For example, if the still image selected by the cursor is the second captured image 2, the control program will move the still image selected by the cursor to the third image when the upper button of the remote controller is pressed. To image 3 captured at
[0116]
In step S53, the control program determines that the still image selected by the cursor has been selected when a predetermined determination button of the remote controller is pressed.
[0117]
In the process of step S54, the control program records data indicating the setting of the still image corresponding to the genre in the hard disk drive 10. For example, a still image of Image 1 is set corresponding to the genre of news, a still image of Image 8 is set corresponding to the genre of movie, and a still image of Image 3 is set corresponding to the genre of baseball. When set, the control program indicates the name of Image 1 corresponding to the news, the name of Image 8 corresponding to the movie, and the image corresponding to Baseball, as shown in FIG. 3 is recorded on the hard disk drive 10.
[0118]
In this way, a still image corresponding to a genre is set according to the operation of the user.
[0119]
Next, a process of displaying an EPG by the CPU 6 executing the control program will be described with reference to a flowchart of FIG.
[0120]
In step S71, the control program causes the graphic chip 15 to display data indicating the contents of the program.
[0121]
For example, the control program supplies EPG data recorded in the hard disk drive 10 or the RAM 7 to the graphic chip 15. The control program causes the graphic chip 15 to supply EPG data to the video D / A converter 16. The video D / A converter 16 displays an EPG screen including a display of data indicating the contents of a program on a display based on the EPG data supplied from the graphic chip 15.
[0122]
In step S72, the control program obtains the genre of the program from the data indicating the contents of the program included in the EPG data. For example, the genre of the program is one of news, movies, baseball, weather, soccer, or documents.
[0123]
In step S73, based on the genre of the program acquired in the process of step S72 and the image corresponding to the genre set in the process of step S54, the control program causes the graphic chip 15 to assign The corresponding still image is displayed, and the process ends.
[0124]
More specifically, the control program, based on the data indicating the setting of the still image corresponding to the genre recorded in the hard disk drive 10, sets the still image set corresponding to the genre of the acquired program. Get the name. For example, if data indicating the name of Image 3 corresponding to baseball is recorded on the hard disk drive 10, the control program stores a still image with the name of Image 3 on the hard disk drive 10 when the genre of the program is baseball. Is read. Since the read still image is encoded, the control program causes the JPEG decoder 19 to decode the data of the read still image. The decoded still image data is supplied to the graphic chip 15.
[0125]
The control program causes the graphic chip 15 to combine the data of the still image with the name of the image 3 so as to correspond to the data indicating the contents of the program of the EPG, and converts the data of the combined image into the video D / A conversion unit 16. To be supplied. The video D / A converter 16 displays an EPG on which a still image having the name of the image 3 is synthesized in accordance with the data indicating the content of the program.
[0126]
In this way, for example, as shown in FIG. 11, in the EPG, a still image set in accordance with the genre of the program is displayed in the program column.
[0127]
