Next, refer to FIG. 3 for the broadcast program recording function. FIG. 3 is a diagram illustrating an example of a processing function according to the first embodiment. The processing function of FIG. 3 is an example, and the present invention is not limited to such a configuration.

This processing function is an example of a recording method or a recording program, and is executed when the recording mode is started. The processing function (F11) for acquiring and presenting the reception sensitivity, the recorded image quality as the recording quality from the standby state, and the recording Include a determination processing function (F12), a recording processing function (F13), and a recording end or recording erasing processing function (F14).

Function F11 is a means for obtaining and presenting reception sensitivity and recorded image quality, detects the reception sensitivity of the broadcast program (step S11), and detects the recorded image quality of the broadcast program (step S12). In this case, the reception sensitivity is an index indicating how the broadcast program being received is received by the mobile device 2, and the recorded image quality is how the mobile device 2 is recorded when the broadcast program is recorded. The reception sensitivity and the recorded image quality have a certain correlation, and since the broadcast program is received by the mobile device 2 that is a mobile device, the location of the mobile device 2 Information that changes according to time.

In the function F11 that has acquired such information, the relationship between the reception sensitivity of the recorded broadcast program and the recorded image quality is presented to the user (step S13). Here, the relationship between the reception sensitivity of the broadcast program and the recorded image quality is, for example, that the recorded image quality corresponding to the reception sensitivity of the broadcast program is presented. If presented, the relationship between the two can be known. Information presentation to the user is executed by displaying an image on the display unit 10.

Function F12 is a means for determining whether recording is possible, and determines whether recording is possible (step S14). The determination of whether or not recording is possible may be an internal process of the portable device 2 or recognize information related to the reception sensitivity of the broadcast program and the recorded image quality presented on the display screen 64 (FIG. 2) of the display unit 10. The user who made it may judge. Based on the determination of whether or not recording can be performed by the function F12, the function F13 is executed when recording is selected, and the function F14 is executed when recording rejection is selected.

The function F13 is a processing means such as recording, and when recording is selected (YES in step S14), recording and saving processing is executed (step S15). Audio is recorded. Even when recording is selected, if the recorded image quality is low, the recording is switched to recording only audio, only the audio not including the image is recorded (step S16), and the process shifts to a standby state.

The function F14 is a processing means for avoiding recording and is processing when recording refusal is selected (NO in step S14). Therefore, if recording is in progress, the recording is ended (step S17), and the recording is completed. If so, the recording is erased (step S18), and a transition is made to a standby state.

With such functions F11, F12, F13, and F14, it is possible to determine whether or not recording is possible according to the presented reception sensitivity and recorded image quality, and as a record that does not include an image when the recorded image quality is low Only audio can be selected and recorded, and various requests from users can be met.

Next, referring to FIG. 4 and FIG. 5 for the presentation of the relationship between the reception sensitivity and the recorded image quality (step S13 of the function F11). FIG. 4 is a flowchart showing a recording level setting processing procedure, and FIG. 5 is a diagram showing a recording level setting screen. 4 and 5 are examples, and the present invention is not limited to such processing procedures and setting screens. In FIG. 5, the same reference numerals as those in FIG.

This processing procedure is an example of processing for setting a reference level for recorded image quality, which is recording quality, and includes a setting menu for recording one-segment broadcasting as a function for presenting the relationship between reception sensitivity and recorded image quality to the user. . This setting menu is a recording operation mode menu set in advance before the start of recording. For example, a sample image representing the image quality is prepared on the image quality display screen. It is a sample that becomes such a recorded image. Therefore, when the recording level setting menu is activated, after the start button is pressed, images from when the reception sensitivity is poor to images with good reception sensitivity are developed in sequence, and the user can record with any image quality allowed. Can be selected and determined. Such a processing procedure is a process of determining the lowest level of recorded image quality in order to shift to recording.

This processing procedure shifts from the initial menu to reception of one-segment broadcasting, and when the recording setting menu is shifted to, as shown in FIG. 4, the setting menu determines whether or not to set the recording level from the recording level setting screen. Then, the recording level setting is started by pressing the start button (YES in step S21). In this case, if the “return button” is pressed, the setting menu returns to the function F11 (FIG. 3).

When the setting of the recording level is started, as a selection screen showing the relationship between the reception sensitivity and the image quality, for example, image quality 1/10 (reception sensitivity: inferior) set in 10 stages, image quality 2/10 (reception sensitivity: The output of the actual image and sound representing the image quality 7/10 (reception sensitivity: good), the image quality 8/10 (reception sensitivity: good), and the selection screen are “next buttons”. "" Is switched to an image quality that gradually increases step by step (steps S22 to S29), and after reaching the selection screen of image quality 10/10 (reception sensitivity: best), the process returns to step S22.

If the “decision button” for image quality is pressed from the display state of each selection screen (depression button for steps S23, S25, S27, and S29 is pressed), the image quality is set as a recording level that is a reference level (step S30). ) When the setting of the recording level is completed, this recording level is set as the lowest level which is the reference level of the allowable recording range. If a “return button” is pressed from the display state of each selection screen, the process returns to step S22, and the recording level can be selected and set again.

In this processing procedure, as shown in FIG. 5A, a recording level setting screen 68 is displayed for recording level setting, and this recording level setting screen 68 has a title display of “recording level setting (image + audio)”. For example, “Please select which level of image quality should be recorded.” Is displayed as a guide message for selecting image quality, and “START / RETURN” is displayed as a selection input. If the “START button” is pressed, the screen shifts to the image quality display screen mode.

As an example of the image quality in a plurality of stages, display screens 70, 72, 74, and 76 having image quality of 1/10 to 10/10 (reception sensitivity: inferior to best) set to 10 stages are shown in FIG. 5C, FIG. 5D, and FIG. 5E, image quality 1/10 (reception sensitivity: inferior), image quality 2/10 (reception sensitivity: less inferior), image quality 7/10 (reception sensitivity: A display button of “next / decision / return” is displayed as a selection button display together with title display of “low”, image quality 8/10 (reception sensitivity: good)... “Next” is a next button for shifting to the next screen, “Determination” is a determination button for determining the image quality, and “Return” is a return button for returning to the display screen of the image quality 1/10. In addition,

real image images

78, 80, 82, 84 representing image quality are displayed at the center of each

display screen

70, 72, 74, 76, and sound is output from the

speakers

46L, 46R.

By the way, the reception sensitivity of one-segment broadcasting and the recording quality index of the broadcast program are, for example, gain control value (AGC: Automatic Gain Control) of the TV tuner unit 6: received signal power: radio wave strength and radio wave quality (C / N value) ): Two power ratios of received power (carrier wave) and noise. If the final image obtained from these noise reduction algorithms in the process of converting these indices and images is presented to the user as a sample image, the recording quality can be expressed as a real image. In this case, it is not necessary for the user to show specific reception sensitivity parameters such as AGC and C / N. As described above, the expression is replaced with a simple expression such as the best, good, or inferior quality of the image. If the resulting image can be confirmed, it is possible to obtain an index for determining which level of the image can be recorded.

Next, refer to FIGS. 6 and 7 for recording level setting. FIG. 6 is a flowchart showing another processing procedure for setting the recording level, and FIG. 7 is a view showing the display screen. 6 and 7 are examples, and the present invention is not limited to such processing procedures. In FIG. 7, the same parts as those in FIG.

As is well known, one-segment broadcasting uses subtitle broadcasting. Therefore, there is a recording mode for not only images and sounds but also images only, that is, caption broadcasting. In this case, as shown in FIG. 6, for the recording level setting selection, processing for recording level setting selection is executed (step S41), and “1” is displayed as an option displayed together with the title “recording level setting selection” on the screen. .. image + sound ”,“ 2. subtitle (image) ”,“ 3. sound ”, and“ return ”may be displayed, and an arbitrary item may be selected from these. In this case, if “1. Image + Sound” is selected, the screen changes to an image and sound quality setting screen (step S42), and if “2. Subtitle (image)” is selected, the subtitle (image) quality setting is set. If the screen is changed (step S43) and “3. voice” is selected, the voice quality setting screen is changed (step S44). In addition, if “return” is selected in “recording level setting selection”, it is possible to return to the initial menu of the function F11 (FIG. 3).

In this case, as shown in FIG. 7, a recording level setting screen 86 is displayed. The recording level setting screen 86 includes “1. Image + Sound” and “2. Subtitles (images) ”and“ 3. Audio ”are displayed, and“ 1, 2, 3 / return ”may be displayed as selection buttons below these.

With such a configuration, it is possible to set a reference level (recording allowable minimum level) for the recording quality from the recording quality of the broadcast program from the image and sound, only the image, or only the sound, and the convenience can be improved.

Next, referring to FIG. 8, FIG. 9, FIG. 10, and FIG. 8 is a diagram showing the level of image quality, FIG. 9 is a flowchart showing a recording processing procedure, FIG. 10 is a diagram showing an image quality display screen, and FIG. 11 is a diagram showing a recording continuation determination screen. 8 to 11 are examples, and the present invention is not limited to such a configuration. 10 and 11, the same parts as those in FIG. 2 are denoted by the same reference numerals.

This notification processing after recording includes a processing procedure for presenting image quality after recording or during recording. In order to execute such processing, it is necessary to monitor the relationship between the recording time and the image quality in real time. FIG. 8 shows data representing the monitoring result, showing the recording time on the X-axis and the image quality level on the Y-axis. In this case, the Y-axis indicates the image quality of the above-described 10 levels, and the X-axis is a bar graph showing the average value of the image quality every minute. By comparing the lengths of the bars on the Y-axis, it is possible to determine the time series transition and quality of the image quality. Based on this pass / fail judgment, it can be used to determine whether or not recording is possible, whether or not to continue recording during recording, and whether or not to save images and sounds after recording, only images, or only audio.

In the time-series transition of the image quality, image quality y ₁ and y ₂ that are lower than the user set quality recording level Lf as the reference level are generated from 31 minutes to 2 minutes after the start of recording. When such image quality deteriorates, an alarm sound is generated from the receiver 44 and the

speakers

46L and 46R, or the vibrator 38 is driven to sound to notify the user of the image quality deterioration. At the same time, a process for inquiring whether to continue or interrupt the current recording is executed automatically or based on a manual operation.

In this processing procedure, as shown in FIG. 9, a selection screen for determining the continuation of recording is displayed (step S51), and “1. continuation of recording” or “2. suspend recording” is selected from this selection screen. Therefore, it is determined whether “1. Continue recording” is selected or “2. Stop recording” is selected (step S52). If “1. Continue recording” is selected, it is determined whether or not to set a recording alarm notification (step S53). If an alarm is set (YES in step S53), the alarm setting mode is set. Start (step S54).

In the alarm setting mode, the alarm setting selection screen is expanded, and the process proceeds to “1. Recorded image quality degradation continuous time setting”, “2. Recorded image quality degradation total number of times”, or “Next” as an alarm generation condition. The user selects whether to do (step S55). When “1. Recorded image quality degradation continuous time setting” is selected, an input screen for the recorded image quality degradation continuous time is developed, and the time desired by the user is input to the displayed time input unit (step S56). When the setting is completed, the process returns to step S55.

If “2. Total number of recorded image quality degradations” is selected, an input screen for the total number of recorded image quality degradations is developed, and the number of times desired by the user is input to the displayed number input unit (step S57). ) When the setting is completed, the process returns to step S55.

If the “next button” is pressed in step S55, the process proceeds to the “next” process (step S58), and the process returns to the function F11 (FIG. 3).

If “2. Recording interruption” is selected in step S52, the recording interruption process is executed (step S59), and the process returns to the function F11 (FIG. 3).

In this case, as shown in FIG. 10, the notification of the image quality after recording is displayed on an image quality display screen 88 representing a temporal transition of the image quality. The image quality display screen 88 includes a graph display unit 90, Below that, a “Next / Back” button is displayed. If the “next button” is pressed, the recording continuation determination screen 92 (FIG. 11) is displayed, and if the “return button” is pressed, the process returns to the function F11 (FIG. 3).

On the recording continuation determination screen 92, as shown in FIG. 11, “1. Recording continuation” and “2. Recording interruption” are displayed as a selection display together with the title “recording continuation determination”, and a selection button “ A 1/2 / next button is displayed. If “1. Recording continuation” is selected, the recording is continued. If “2. Recording interruption” is selected, the recording is interrupted. If “Next button” is pressed, the process proceeds to “Next” processing.

As shown in FIG. 12, the alarm setting screen 93 has a title “recording alarm notification mode setting” and “1. recorded image quality deterioration continuous time setting” and “2. recorded image quality deterioration total number setting” as selection display. Is displayed, and a “1/2 / next” button is displayed as a selection button in the lower part thereof. If “1. Recorded image quality deterioration continuous time setting” is selected, the setting process of the recorded image quality deterioration continuous time is performed. If “2. Recorded image quality deterioration total number of times setting” is selected, the recorded image quality deterioration total time is set. When the number setting process is performed and the “next button” is pressed, the process proceeds to the “next” process.

As shown in FIG. 13, the setting screen 95 for the recorded image quality degradation continuous time is displayed with a time input unit 97 together with the title “recorded image quality degradation continuous time setting”. Is displayed, and a “setting complete / return” button is displayed as a selection button in the lower part. If time is input to the time input unit 97 and “setting completed” is selected, the setting is completed, and if “return” is selected, the process proceeds to the previous process.

As shown in FIG. 14, the setting screen 99 for the total number of times of recorded image quality deterioration displays the number input unit 101 together with the title “recorded image quality deterioration total number of times setting”. Is displayed, and a “setting complete / return” button is displayed as a selection button in the lower part. If the number is input to the number input unit 101 and “setting completed” is selected, the setting is completed, and if “return” is selected, the process proceeds to the previous process.

Next, the setting menu and setting function for image quality display are as follows.

1. Recorded image quality degradation continuous time setting A function for notifying the user of an alarm when the recorded image quality falls below the quality level set by the user for a predetermined time continuously.

2. Recorded image quality degradation total number of times setting Function to specify the number of times that the user falls below the quality level set by the user within the recording time specified by the user, and to notify the user of an alarm when the quality level falls below that number. In this case, the number of times that the quality level is lower is, for example, when the image quality is detected at a predetermined time interval, and the number of detections may be set as a unit of counting. It can be detected by the number of times.

3. When an alarm is notified in any of the

above items

1 and 2, a function is provided that can perform the following operations.
a Setting to record to the end without alarm notification (Default is alarm notification).
b Function to automatically stop recording.
c Function to change the recording mode to audio-only recording and continue recording.
The above setting menu can also be set before recording starts. When the continuation determination is made, it may be displayed as a subsequent screen, or the display may be avoided.

Next, refer to FIG. 15 for the recording setting process. FIG. 15 is a flowchart showing the transition of the recording setting process. The processing procedure shown in FIG. 15 is an example, and the present invention is not limited to such a processing procedure.

As shown in FIG. 15, the transition state of the setting menu described above is displayed when an alarm is generated, and the alarm mode is displayed when the image quality is determined by the user judgment and the recording is continued. By changing to a setting screen (for example, FIG. 12, FIG. 13, FIG. 14), future recording mode settings may be changed.

Therefore, this processing procedure is a comprehensive processing procedure including a processing procedure for setting a recording level, generating a recorded image quality alarm, and the like from the recording start menu. A part corresponding to the above-described processing is assigned a figure number to clearly indicate the correspondence.

When the recording setting menu is started (step S61), the recording setting menu is presented on the display unit 10, and the user selects the recording level setting or the alarm operation mode setting (step S62). If the recording level setting is selected in step S62, the recording level of “image + sound”, “image only” or “sound only” is selected (step S63). The recording level is the recording format of the broadcast program that is switched when the recorded image quality does not reach the reference level. In “image + audio”, the image and audio are recorded simultaneously, and “image only” Even if there is sound, it is a record of only the image, and “sound only” is a record of only the sound even if there is an image.

In step S63, any one of “image + sound”, “image only”, and “sound only” is selected to set the recording level (step S64). In this case, a reference level for determining whether or not to record a broadcast program is set. This reference level is the lowest level in the recording allowable range of the user when the image quality of the broadcast program is recorded in the broadcast program.

If the recording level and the reference level are to be reset after the reference level is set, the process returns to step S62. If the set recording level and the reference level are not to be reset, the selection of the presence / absence of alarm notification (step The process proceeds to S65).

When the recorded image quality alarm is generated (step S66), selection is made as to whether to continue recording or to stop recording (step S67). Selection without change (step S68) is performed. If the recording is interrupted in step S67, the recording interruption process (step S69) is executed.

In step S68, when the recording level change is selected, the recording level is set (step S64). When “no recording level change” is selected, the process proceeds to selection of presence / absence of alarm notification (step S65).

In step S65, when notification of an alarm is selected, selection is made between automatic recording stop and user stop (step S70). When the user's judgment is requested, the recording stop is left to the user operation. If automatic stop is selected, the recording is automatically interrupted or stopped when an alarm is generated (step S71). When stop by the user is selected, selection of setting of the recorded image quality deterioration continuous time or setting of the total number of times of recorded image quality deterioration is performed (step S72), and setting of the recorded image quality deterioration continuous time is selected. If the recorded image quality deterioration continuous time is set (step S73), and if the recorded image quality deterioration total number of times is selected, the recorded image quality deterioration total number of times is set (step S74). If none of these is selected, the selection of whether or not to record only audio (step S75) is executed. If only the audio is selected, only audio is recorded (step S75). After step S76) is executed, the process returns to step S62, and also when no audio-only recording is performed, the process returns to step S62.

If there is no alarm notification in step S65, the process of recording in the designated mode (step S77) will be executed without any alarm notification in the future, and the process will return to step S62.

Next, referring to FIG. 16 and FIG. 17 for the recording state display during recording. FIG. 16 is a flowchart showing an example of a recording state display processing procedure, and FIG. 17 is a view showing a standby screen having a recording state display. The display of the recording state in FIGS. 16 and 17 is an example, and the present invention is not limited to such a display form. In FIG. 17, the same parts as those in FIG.

The recording status during recording may be confirmed by, for example, an icon. If the shape of the icon is fixed and whether the recorded image quality exceeds or below the user-set recording image quality is displayed, the user can easily check the status. I can confirm.

This processing procedure is an example of processing for displaying a recording state during recording on the standby screen. As shown in FIG. 16, when recording is started, the recording state display mode is started. When information input or communication is not performed, a standby screen is displayed on the display unit 10 (step S81). Whether or not recording is in progress is determined (step S82), and if recording is in progress (YES in step S82), icons indicating recording and recorded image quality are displayed on the standby screen (step S83). If the recording is not in progress (NO in step S82), no such icon is displayed.

During recording, it is determined whether or not the image quality exceeds the reference level set by the user (step S84). If the image quality exceeds the reference level (YES in step S84), an icon is displayed, for example. If the display is blue (step S85) and the image quality is below the reference level (NO in step S84), the icon is displayed in red, for example (step S86).

In such a recording and display of the recorded image quality, when in a standby state, a standby screen 94 is displayed as shown in FIG. 17A, and when recording is in progress, recording is indicated in the upper right of the standby screen 94. If the icon 96 is displayed and the recording state exceeds the reference level, the icon 96 is displayed in blue 98 as shown in FIG. 17B. If the recording state is below the reference level, the icon 96 is displayed in FIG. 17C. As shown, the icon 96 may be a red display 100.

With such an icon display, the user can recognize that recording is in progress, can recognize whether the image quality is good or not by the display color, and can use it to determine whether recording should be continued or interrupted. .

[Second Embodiment]

For the second embodiment, refer to FIG. 18 and FIG. FIG. 18 is a diagram illustrating an example of a portable device, and FIG. 19 is a flowchart illustrating an example of image processing for recording reservation. The configuration shown in FIGS. 18 and 19 is an example, and the present invention is not limited to such a configuration. In FIG. 18, the same parts as those in FIG.

In this embodiment, the recording reservation can be made, and in the recording reservation processing as an example, the quality of the received image is judged before the reservation time comes. If the configuration is such that the quality of the received image is determined before the scheduled time arrives, useless processing such as recording interruption due to a decrease in image quality after the start of recording can be avoided.

In this embodiment, as shown in FIG. 18, the portable device 2 includes a recording reservation unit 14. The recording reservation unit 14 includes a timer as a time measuring means and a storage means for storing a broadcast program to be reserved for recording, and is controlled by the processor 4 to start recording a specific broadcast program at a predetermined date and time and end the recording. . The display unit 10 is used to display a broadcast program recording reservation, and the input operation unit 12 is also used to input a broadcast program recording reservation. Since the other configuration is the same as that of the first embodiment, the same reference numerals as those in FIG. 1 are given to FIG. 18 and the description thereof is omitted.

The processing function of the image processing including the recording reservation process is an example of a recording method or a recording program, and is executed by starting a recording mode including the recording reservation process. In addition to the quality acquisition and presentation processing function (F21), in the same way as in the first embodiment, a recording availability determination processing function (F22), a recording processing function (F23), and a recording end or recording erasing processing function ( F24).

Function F21 is a recording reservation execution means, and starts up before the reservation time (step S91). In the activation before the reserved time, if there is a recording reservation, reception of the broadcast program is started within a predetermined time before the reservation time arrives. As a result of the activation before the reserved time, the received image quality of the broadcast program being received is acquired (step S92), and it is determined whether or not to perform the preset recording (step S93). If it is not recorded, that is, if the image quality is below the reference level, an inquiry is made to the user (step S94). That is, the display screen of the display unit 10 is notified that the recorded image quality is low, and a determination is made as to whether or not to execute recording. At this stage, the user can reject recording or reset the recording mode (step S95). In step S93, if it is a preset recording operation, the process of step S95 is executed without the inquiry of step S94.

The function F22 is a determination processing unit for determining whether recording is possible, and determines whether recording is possible (step S96). The determination of whether or not recording is possible may be an internal process of the portable device 2 or recognize information related to the reception sensitivity of the broadcast program and the recorded image quality presented on the display screen 64 (FIG. 2) of the display unit 10. The user who made it may judge. Based on the determination of whether or not recording can be performed by the function F22, the function F23 is executed when recording is selected, and the function F24 is executed when recording rejection is selected.

Function F23 is a processing means such as recording, and when recording is selected, recording and storage processing is executed (step S97), and in this recording and storage processing, images and sound are recorded. Even when recording is selected, if the recorded image quality is low, the recording is switched to recording only sound, only the sound not including the image is recorded (step S98), and the process shifts to a standby state.

The function F24 is a processing means for avoiding recording and is processing when the recording refusal is selected. Therefore, if recording is in progress, the recording is terminated (step S99). The recording is erased (step S100), and a transition is made to a standby state.

According to such processing of the functions F21, F22, F23, and F24, it is possible to determine whether recording is possible according to the presented reception sensitivity and recorded image quality, and recording that does not include an image when the recorded image quality is low. As described above, it is possible to select and record only voice, and respond to various requests of users.

Thus, before scheduled recording, the recorded image quality is determined and presented to the user, and if the user can determine whether recording is possible, recording with good recording quality can be performed, and the reception sensitivity and recorded image quality are reconfirmed. By changing the reference level, etc., recording corresponding to the recorded image quality that changes with the location and time of the portable device 2 can be performed.

Next, referring to FIG. 20, FIG. 21, FIG. 22 and FIG. 23 for the confirmation process of the recording state before recording. FIG. 20 is a flowchart showing the processing procedure of the image quality confirmation process before recording, FIG. 21 is a diagram showing an image quality confirmation screen before recording, FIG. 22 is a diagram showing a pre-recording judgment screen, and FIG. It is a figure which shows transition of the image quality before recording. 20 to 23 are examples of the recorded image quality confirmation processing, and the present invention is not limited to such processing.

In this processing procedure, the recording state of a broadcast program is detected before recording, and the user confirms the recording state in advance, and such processing is executed when recording is set.

In this processing procedure, if it is specified that pre-recording image quality confirmation is performed after the recording reservation is completed, an image quality confirmation screen is displayed before recording (step S101), and a predetermined time before recording is recorded from this image quality confirmation screen. For example, if 20 minutes is designated, the image quality confirmation operation is started 20 minutes before the designated time for confirming the pre-recording image quality (step S102), and the recorded image quality is automatically measured. . When the measurement result is a certain time before recording, for example, 5 minutes before recording, a display screen of the recorded image quality is displayed, and the operation of the vibrator 38 and / or an alarm sound is generated (step S103). The user confirms the image quality and is required to determine whether or not to record in 5 minutes until the start of recording (step S104).

In the recorded image quality display screen, it is determined whether or not there is an input operation (step S105). If there is an input operation, it is determined whether or not the operation key is operated except for the recording continuation determination (step S106). If the key operation is related to the continuation of recording, it is determined whether or not the recording is continued (step S107). If the recording is not continued (NO in step S107), the reserved recording is canceled. Then, the recording quality level is changed, and the reserved recording is continued (step S108).

If it is determined in step S105 that there is no input operation, a key operation other than the recording continuation determination in step S106, that is, another key operation, or a case where recording is continued in step S107 (YES in step S107), The display screen is erased and the recording process is started (step S109).

In this image quality confirmation, as shown in FIG. 21, an image quality confirmation screen 102 is displayed in the image quality confirmation before recording, and the image quality confirmation screen 102 displays, for example, “image quality before recording” as a confirmation message. “Do you want to confirm?” And “1.Yes” and “2.No” are displayed as options for the intention to confirm, and the time input unit 104 is displayed below “1.Yes”. In addition, “setting complete / return” is displayed as a selection input.

When “1. Yes” on the image quality confirmation screen 102 and the time are input to the time input unit 104 or “2. No” is selected and “Setting is completed” is selected, the setting is completed.

When a predetermined time before the start of recording, for example, 5 minutes before, a pre-recording determination screen 106 (FIG. 22) is displayed. As shown in FIG. 22, the pre-recording judgment screen 106 is displayed with the title “pre-recording judgment” as a title, and a bar graph display 108 representing the image quality at a predetermined time interval and a user-set quality recording level that is a user-set reference level. Whether or not Lf is exceeded is displayed, and “1. Continue” and “2. Stop” are displayed below the bar graph display 108 as options for selecting whether or not to continue recording. If “1. continuation” or “2. stop” is selected with the key 58 (FIG. 2) and the determination key 60 (FIG. 2) is pressed, the reservation recording is continued by selecting “1. continuation”, or “2 .. “Stop” will stop scheduled recording.

As shown in FIG. 23, the bar graph display 108 is a bar graph in which the horizontal axis indicates the pre-recording time and the vertical axis indicates the image quality. For example, the user-set quality recording level Lf is set to “good” for the image quality. If it is higher than this level Lf, an image quality of good or better can be obtained. Therefore, the image quality can be visually recognized by the length of the bar on the bar graph. The image quality is measured and displayed for a certain unit time, for example, 1 minute, until 5 minutes before the start of recording. If the display of such image quality is confirmed, the image quality can be recognized easily and with high accuracy, and it becomes influential information on whether to continue or stop recording.

Next, FIG. 24 will be referred to for the image quality confirmation screen display and selection process for recording reservation. FIG. 24 is a flowchart showing a processing procedure of image quality confirmation processing before recording. FIG. 24 shows an example of the image quality confirmation processing, and the present invention is not limited to such processing.

When the recording reservation is completed, the pre-recording image quality confirmation screen 102 (FIG. 21) is displayed (step S111). In the pre-recording image quality confirmation screen 102, either “1. Yes” or “2. No” is displayed. Is selected (step S112). In this case, if “2. No” is selected, the process returns to the process of the function F21 (FIG. 19). If “1. Yes” is selected, recording is performed. The test recording period for confirming the quality of the previous image is set (step S113), and when a predetermined time, for example, 5 minutes before the start of recording, is reached, the display of the pre-recording judgment screen 106 (FIG. 22), vibrator, alarm sound The occurrence alerts the user that the pre-recording determination screen 106 has been displayed (step S114).

In this pre-recording determination screen 106 (FIG. 22), it is determined whether “1. continuation” has been selected or “2. stop” has been selected (step S115), and when “1. continuation” has been selected. Executes the recording continuation process (step S116), ends the process, and returns to the process of the function F21 (FIG. 19). When “2. Stop” is selected, a recording stop process is executed (step S117), and the process returns to the function F21 (FIG. 19).

In this way, the image quality of the actual image is confirmed by the broadcast program before the recording start time reserved by the user arrives, and the recorded image quality at the time specified by the user is received by another broadcast program before the start of the broadcast program. To measure the recorded image quality and confirm the recorded image quality before the start of the reserved program of the same broadcast as the reserved program. Since this image quality check is performed at a time immediately before the start time of the reserved program, the accuracy of checking the recorded image quality can be improved.

The function F31 includes a function (f311) for measuring the relationship between reception sensitivity and recorded image quality, a function (f312) for determining the relationship between position information and time information, reception sensitivity and / or position information, and recorded image quality. And a function (f313) for presenting a relationship with

The function F31 is a means for measuring the reception sensitivity and / or the relationship between the position and the recorded image quality, and presenting the measurement result. In the function f311, the reception sensitivity of the broadcast program is detected (step S121). The recorded image quality of the broadcast program is detected (step S122). In the function f312, the GPS position information is acquired by receiving the GPS signal by the GPS unit 8 (step S123), the relationship between the GPS position information and time information is obtained (step S124), and the mobile phone at the time when the broadcast program is recorded is obtained. The position information of the device 2 is obtained. Also, in the function f313, the relationship between the reception sensitivity measured in the function f311 and the recorded image quality is presented to the user (step S125), the position information measured in the function f312 and the recorded image quality obtained in the function f311 are presented. Is presented to the user (step S126). These presentations are displayed as images on the display unit 10 as in the first or second embodiment.

Function F32 is a means for determining whether or not recording is possible, and determines whether or not recording is possible (step S127). The determination of whether or not recording is possible may be an internal process of the portable device 2 or recognize information related to the reception sensitivity of the broadcast program and the recorded image quality presented on the display screen 64 (FIG. 2) of the display unit 10. The user who made it may judge. Based on the determination of whether or not recording can be performed by the function F32, the function F33 is executed when recording is selected, and the function F34 is executed when recording refusal is selected.

The function F33 is a processing means for recording and the like, and is processing when recording is selected (YES in step S127), and executes recording and saving processing (step S128). In this recording and saving processing, Images and sounds are recorded. Even when recording is selected, if the recorded image quality is low, the recording is switched to recording only sound, only the sound not including the image is recorded (step S129), and the process shifts to a standby state.

The function F34 is a processing means for avoiding recording and is processing when recording refusal is selected (NO in step S127). Therefore, if recording is in progress, the recording is ended (step S130), and the recording is completed. If so, the recording is erased (step S131), and a transition is made to a standby state.

If such functions F31, F32, F33, and F34 are provided and the above processing is executed, whether or not recording can be performed can be determined according to the presented reception sensitivity and / or position information and recorded image quality, and the recorded image quality can be determined. Is low, it is possible to select and record only audio as a recording that does not include an image, and can respond to various requests of users.

Referring to an example of the recording quality confirmation operation using the position information as described above, it is assumed that a specific user A wants to record a broadcast program for 2 hours from 9 pm by receiving one-segment broadcasting. In this time zone, the worker is usually returning home from work, and travel time of about 1 hour 30 such as traveling by train or bus by transportation or walking is spent. In order to know in advance the recorded image quality during this travel time, the received image quality information (FIG. 27) may be acquired by the image quality measurement and presentation function.

In this received image quality information, as shown in FIG. 27, the horizontal axis indicates the image quality, and the vertical axis indicates the position information. Position 1: Company X, Position 2: Y station, Position 3: Z station, Position 4: Bus stop, Position 5: Home The image quality at each position is shown by a bar graph, and Lf is a user-set quality recording level that is a reference level of the user setting as described above.

In this received image quality information, L1 is a moving period between Position1 and Position2, L2 is a moving period between Position2 and Position3, L3 is a moving period between Position3 and Position4, and L4 is a moving period between Position4 and Position5. It is the average value of each image quality in. As described above, the image quality below the reference level is a determination target of whether or not the user can record.

Therefore, if this received image quality information (FIG. 27) is the quality record of the past recorded image when returning home from Company X at 9:00 pm, referring to this quality record, moving from 9:00 pm It is predicted that there will be no problem.

Next, in the processing procedure using the relationship between the position information and the image quality, a recording image quality confirmation position registration process is performed, and a process for determining whether to record from the image quality at the position is performed. Just do it. As shown in FIG. 28, the received image quality information display screen at the registered recorded image quality confirmation position is displayed (step S141), and the operation proceeds to the recording image quality information acquisition operation on this received image quality information display screen.
