  In addition, the camera signal processing circuit 3 controls the image sensor 2 to output image data at an NTSC rate (hereinafter referred to as a normal rate as appropriate) output from the image sensor 2 or an NTSC rate. High-speed, high-rate image data is subjected to correlated double sampling, A / D (Analog / Digital) conversion, interpolation, and other necessary processing and supplied to SDRAM (Synchronous DRAM (Dynamic Random Access Memory)) 4 To do.

  The SDRAM 4 temporarily stores the image data supplied from the camera signal processing circuit 3. The SDRAM 4 has at least a storage capacity capable of storing high-rate image data for a predetermined time such as 3 seconds.

  Under the control of the microprocessor 10, the recording / reproducing circuit 5 reads out the image data stored in the SDRAM 4 as normal-rate image data and supplies the image data or the image data and the microphone (microphone) 8. The recorded audio data is recorded on a recording medium (data recording medium) 7.

  The recording / reproducing circuit 5 reproduces normal-rate image data from the recording medium 7 and supplies it to the superimposing circuit 12 under the control of the microprocessor 10. Note that the recording / reproducing circuit 5 has the normal rate image data (attached to the normal rate image data) recorded on the recording medium 7 and, when the audio data is recorded, the normal rate image data and the normal rate image data.

  The key input circuit 9 is connected to a mechanical button such as a recording button 9A that is operated when recording is started or stopped, and an operation signal corresponding to the operation of the recording button 9A or the like is sent to the microprocessor 10. Supply.

  The microprocessor 10 executes a program stored in the non-volatile memory 20 to control recording, display, and the like of image data and audio data with the camera of FIG.

  For example, the microprocessor 10 A / D converts a voltage as an operation signal supplied from the key input circuit 9 or the touch panel 14 and determines a button operated by the user from digital data obtained by the A / D conversion. . Further, the microprocessor 10 performs various controls based on the determination result of the button operated by the user and the recording or reproducing state in the recording / reproducing circuit 5.

  Specifically, for example, the microprocessor 10 controls the lens unit 1, the camera signal processing circuit 3, and the recording / reproducing circuit 5, thereby obtaining image data obtained by the image sensor 2, and if necessary, The audio data obtained by the microphone 8 is recorded on the recording medium 7, and image data and further necessary audio data are reproduced from the recording medium 7 by controlling the recording / reproducing circuit 5.

  For example, the microprocessor 10 supplies bitmap data such as CG (Computer Graphics) for performing OSD (On Screen Display) display and various commands to the OSD circuit 11.

  In addition, the microprocessor 10 controls the power control switch 19 and reads / writes data from / to the nonvolatile memory 20.

  The OSD circuit 11 has a built-in VRAM (Video RAM (Random Access Memory)) (not shown) and develops (stores) bitmap data from the microprocessor 10 in the VRAM. The OSD circuit 11 interprets a command from the microprocessor 10 and develops bitmap data such as CG for which OSD display is requested by the command in the VRAM. Then, the OSD circuit 11 supplies image data as bitmap data developed in the VRAM to the superimposing circuit 12 in a predetermined scanning unit.

  The line-out terminal 13 outputs the image data from the superimposing circuit 12 to the outside. For example, an external device (not shown) such as a television receiver is connected to the line-out terminal 13.

  The touch panel 14 is, for example, a panel in which an LCD (Liquid Crystal Display) panel and a touch sensor are integrated. The LCD panel displays an image corresponding to image data from the superimposing circuit 12 on the LCD panel. The position of the LCD panel touched by the user is detected, and an operation signal corresponding to the position is supplied to the microprocessor 10.

  The viewfinder panel 15 is, for example, an LCD panel provided in a viewfinder (not shown), and displays an image corresponding to the image data from the superimposing circuit 12.

  The battery 16 supplies power to each block constituting the camera of FIG. The battery 16 can be charged via the power circuit 18 by connecting an AC (Alternating Current) cable 17 to an AC outlet.

  The AC cable 17 is a cable used when connecting the power supply circuit 18 and an AC outlet, and is detachable from the camera of FIG.

  When the AC cable 17 is connected to an AC outlet, the power supply circuit 18 generates a necessary power source from the voltage and current from the outlet and supplies it to the necessary blocks constituting the camera of FIG. At the same time, the battery 16 is charged as necessary.

  In addition, when the AC cable 17 is not connected to an AC outlet, the power supply circuit 18 supplies the voltage and current of the battery 16 as a power source to the necessary blocks constituting the camera of FIG.

  The power control switch 19 is turned on or off according to the control of the microprocessor 10 to turn on or off the supply of power to the blocks other than the microprocessor 10 among the blocks constituting the camera of FIG. To do. The microprocessor 10 is always supplied with power from the power supply circuit 18.

  In the camera configured as described above, the image sensor 2 receives light from the lens unit 1 and image data (hereinafter also referred to as captured image data as appropriate) as an electrical signal corresponding to the amount of light. The signal is supplied to the SDRAM 4 via the camera signal processing circuit 3 and temporarily stored.

  Image data stored in the SDRAM 4 is read therefrom and supplied to the recording / reproducing circuit 5 and the superimposing circuit 12. The superimposing circuit 12 adds the image data supplied from the OSD circuit 11 (hereinafter also referred to as OSD image data as appropriate) to the captured image data supplied from the imaging device 2 via the camera signal processing circuit 3 and the SDRAM 4. The image data obtained by superimposing as necessary is supplied to the touch panel 14 and the viewfinder panel 15. As a result, a so-called through image is displayed on the touch panel 14 and the viewfinder panel 15.

  When the user operates the recording button 9A and an operation signal corresponding to the operation is supplied from the key input circuit 9 to the microprocessor 10, the microprocessor 10 controls the recording / reproducing circuit 5 and the recording medium 7 Start recording to.

  That is, in this case, the recording / reproducing circuit 5 records the captured image data supplied from the SDRAM 4 together with the audio data supplied from the microphone 8 on the recording medium 7.

  Thereafter, when the user operates the recording button 9A again and an operation signal corresponding to the operation is supplied from the key input circuit 9 to the microprocessor 10, the microprocessor 10 controls the recording / reproducing circuit 5 to record the recording medium. Stop recording to 7.

  As described above, the camera of FIG. 1 captures and records (records) an image. As an image capturing mode that is an image capturing mode, for example, the image sensor 2 has an NTSC rate (60 Hz). ) Is a normal imaging mode that outputs image data at a normal rate, and a high-speed imaging mode that outputs image data at a high rate such as 240 Hz, which is faster than the normal rate.

  In the normal imaging mode, the imaging device 2 performs imaging at a normal rate, and the captured image data at the normal rate is supplied to the SDRAM 4 via the camera signal processing circuit 3 and temporarily stored.

  Further, in the normal imaging mode, the captured image data stored in the SDRAM 4 is read as it is as normal-rate image data and supplied to the recording / reproducing circuit 5. The recording / reproducing circuit 5 records the captured image data at the normal rate from the SDRAM 4 together with the audio data supplied from the microphone 8 on the recording medium 7.

  On the other hand, in the high-speed imaging mode, the imaging device 2 performs imaging at a high rate, and the high-rate captured image data is supplied to the SDRAM 4 via the camera signal processing circuit 3 and temporarily stored.

  Furthermore, in the high-speed imaging mode, for example, imaging of high-rate captured image data for a predetermined time set in advance is completed, and thereby high-rate captured image data for the predetermined time is stored in the SDRAM 4. Then, the high-rate captured image data stored in the SDRAM 4 is read as normal-rate image data and supplied to the recording / reproducing circuit 5. The recording / reproducing circuit 5 records the high-rate captured image data read out from the SDRAM 4 as normal-rate image data together with the audio data supplied from the microphone 8 on the recording medium 7.

  Next, the operation of the camera of FIG. 1 in the high-speed imaging mode will be further described with reference to FIG.

  In FIG. 2, the horizontal axis represents time.

  The first from the top in FIG. 2 shows high-rate captured image data captured in the high-speed imaging mode.

For example, at time t _1, the user operates the recording button 9A (FIG. 1), the imaging device 2 starts imaging in four times 240Hz normal rate which is NTSC system rate (60 Hz), thereby Outputs 240 Hz captured image data as a high rate. The high-rate 240 Hz captured image data is supplied to and stored in the SDRAM 4 via the camera signal processing circuit 3.

In the image sensor 2, high-rate imaging for a time T _B (for example, 3 seconds) as a predetermined time is completed, whereby high-rate captured image data for the time T _B is stored in the SDRAM 4. Then, the recording / reproducing circuit 5 reads the high-rate captured image data stored in the SDRAM 4 as normal-rate image data, and records it on the recording medium 7 together with the audio data supplied from the microphone 8.

  That is, the second from the top in FIG. 2 shows the timing for reading the captured image data from the SDRAM 4 in the high-speed imaging mode and the timing for recording the captured image data on the recording medium 7. The third (first from the bottom) shows the recording timing of the audio data captured by the microphone 8 on the recording medium 7 in the high-speed imaging mode.

Now, from time t ₁ to the recording button 9A it has been operated, the time that has elapsed by a predetermined time T _B is, when a time t _2, the high-speed imaging by the imaging element 2 and ends at time t _2, the thereby , the SDRAM 4, the captured image data of a high rate of time T _B content is stored.

As shown second from the top in FIG. 2, the recording / reproducing circuit 5 reads the captured image data from the SDRAM 4 and records the captured image data to the recording medium 7 from time t ₂ when the high-speed imaging by the image sensor 2 is completed. Start recording.

Here, the high-rate captured image data stored in the SDRAM 4 is read as normal-rate image data. Thus, for example, as described above, a high rate, if it is four times the rate of the normal rate, the image data of the high rate of the stored time T _B content in SDRAM4 is four times T _B Time T _R = 4 × T _B of normal rate image data.

Then, the image data of the normal rate time T _R min read from SDRAM4 via the recording and reproduction circuit 5 and recorded on the recording medium 7.

Incidentally, a high rate, if the ratio between the normal rate (High Rate / [Normal Rate), when that rate ratio, that the SDRAM 4, the captured image data of a high rate of time T _B content is stored , the read from SDRAM4 becomes captured image data of the normal rate of time T _R min rate ratio times the time T _B.

  When the high-speed imaging by the imaging device 2 is completed, as described above, the microphone 8 is read in parallel with reading of the captured image data stored in the SDRAM 4 and recording of the captured image data on the recording medium 7. Recording of the audio data captured by the recording medium 7 is started.

That is, the recording / reproducing circuit 5 starts recording the audio data captured by the microphone 8 onto the recording medium 7 from time t ₂ when the high-speed imaging by the imaging device 2 is completed, as shown in the third from the top in FIG. To do.

Thus, recording captured image data of the high rate of the obtained time T _B min by high-speed imaging from the time t _1, the recording medium 7 as four times the image data of the normal rate time T _R min of time T _B and that, from time t ₂ the high-speed imaging is completed, and the recording the time T _B worth of audio data captured by the microphone 8 to the recording medium 7 is performed.

Then, the recording and reproducing circuit 5, when the recording on the recording medium 7 of the image data of the normal rate time T _R min ends, ends also recorded on the recording medium 7 of the voice data captured by the microphone 8.

That is, for example, from time t ₂ the high-speed imaging is completed, the time that has elapsed by the time T _R, when the time t _3, the high rate of time T _B fraction obtained by high-speed imaging from the time t ₁ captured image data recording and the recording medium 7 as the image data of four times the normal rate time T _R min of time T _B, the time t _2, the recording time T _B worth of audio data captured by the microphone 8 the recording of the medium 7, and ends at time t _3.

As described above, in the SDRAM 4, the first and high rate temporarily stores captured image data as rate, captured imaging image data of a high rate for a predetermined time T _B caused by the image pickup element 2 the image sensor 2 outputs After completion of the processing, the captured image data stored in the SDRAM 4 is read as normal-rate image data as a second rate different from the high rate, and recorded on the recording medium 7 together with the audio data obtained by the microphone 8. Thus, it is possible to record the image data to be reproduced in the pseudo slow reproduction together with the image data to be reproduced in the pseudo slow reproduction.

That is, the captured image data of a high rate for a predetermined time T _B min, temporarily stored in the SDRAM 4, reads as captured image data of the rate ratio multiplied content of the normal rate time T _B, when recorded on the recording medium 7 , the 1-speed captured image data from the recording medium 7 during playback in the (image data of the normal rate, the reproduction speed to play in real-time), the predetermined time T _B content of the higher rate as the recording medium captured image data In the same manner as in the case of recording at 7 times and slow playback at 1/4 times speed (1/4 speed when high speed image data is played back in real time), for example, golf swing A pseudo slow reproduction is performed in which an image that can clearly confirm the state of the subject moving at high speed, such as the state of the person who is performing, is displayed.

  Furthermore, since the reproduction speed of the data from the recording medium 7 is 1 × speed, the audio data recorded on the recording medium 7 is reproduced at the same reproduction speed as when recorded on the recording medium 7. It is possible to prevent a low-pitched sound that has been extended and difficult to hear, such as when playing at double speed.

Here, the captured image data of a high rate for a predetermined time T _B component, if temporarily stored in SDRAM 4, reads as captured image data of the rate ratio multiplied content of the normal rate time T _B, were recorded on the recording medium 7 The pseudo slow reproduction as described above, which is performed when the captured image data is reproduced from the recording medium 7 at 1 × speed, is hereinafter referred to as smooth slow reproduction as appropriate.

Also, to be able to perform smooth slow reproduction, the captured image data of a high rate for a predetermined time T _B min, temporarily stored in the SDRAM 4, as captured image data of the rate ratio multiplied content of the normal rate time T _B Reading and recording on the recording medium 7 is hereinafter referred to as smooth slow recording as appropriate.

Then, the smooth slow recording 2, from time t ₁ to the operation of the recording button 9A by the user is, the captured image data of a high rate of time t _B min until the time t ₂ has elapsed by the time T _B, The captured image data stored in the SDRAM 4 and recorded in the SDRAM 4 is recorded in the recording medium 7. However, for example, the time T _B goes back from the time when the user operates the recording button 9A. High-rate captured image data for time t _B up to the time can be stored in the SDRAM 4, and the captured image data stored in the SDRAM 4 can be recorded on the recording medium 7.

  That is, FIG. 3 is a diagram for explaining another operation of the camera of FIG. 1 in the high-speed imaging mode.

  In FIG. 3, the horizontal axis represents time.

  The first from the top of FIG. 3 shows high-rate captured image data captured in the high-speed imaging mode.

  When the imaging mode is set to the high-speed imaging mode, the imaging device 2 (FIG. 1) starts high-speed imaging, and high-rate captured image data obtained by the high-speed imaging is transmitted from the imaging device 2 to the camera signal processing circuit 3. To the SDRAM 4.

SDRAM4 from the image pickup element 2, the captured image data of a high rate are memorized supplied via the camera signal processing circuit 3, after storing the captured image data of a high rate for a predetermined time T _B content is new When such high-rate captured image data is supplied, the new high-rate captured image data is stored in the form of overwriting the oldest high-rate captured image data.

Then, 'in, the user operates the recording button 9A (FIG. 1), the imaging device 2 interrupts the fast operation, the recording and reproducing circuit 5, a time t _2' time t ₂ time going back from a time period T _B the captured image data of a high rate of time T _B min 'to the time t _2' t ₁ until, as the image data of the normal rate time T _R min is read from SDRAM 4, together with the audio data supplied from the microphone 8, the recording Recorded on the medium 7.

  That is, the second from the top in FIG. 3 shows the timing for reading the captured image data from the SDRAM 4 in the high-speed imaging mode and the timing for recording the captured image data on the recording medium 7. The third (first from the bottom) shows the recording timing of the audio data captured by the microphone 8 on the recording medium 7 in the high-speed imaging mode.

As shown second from the top in FIG. 3, the recording / reproducing circuit 5 reads the captured image data from the SDRAM 4 and reads the captured image data to the recording medium 7 from the time t ₂ ′ when the recording button 9A is operated. Start recording.

  Here, the high-rate captured image data stored in the SDRAM 4 is read as normal-rate image data.

  When the recording button 9A is operated, as described above, the microphone 8 reads the captured image data stored in the SDRAM 4 and records the captured image data on the recording medium 7 in parallel. Recording of the captured audio data onto the recording medium 7 is started.

That is, the recording / reproducing circuit 5 starts recording the audio data captured by the microphone 8 onto the recording medium 7 from the time t ₂ ′ when the recording button 9A is operated, as shown third from the top in FIG. .

Thus, 'from the time t _2' time t ₂ the high rate of the captured image data of the time T _B fraction obtained by high-speed imaging up, four times the normal rate time T _R min of time T _B Recording as image data on the recording medium 7 and recording of audio data captured by the microphone 8 on the recording medium 7 are performed.

Then, the recording and reproducing circuit 5, when the recording on the recording medium 7 of the image data of the normal rate time T _R min ends, ends also recorded on the recording medium 7 of the voice data captured by the microphone 8.

Thus, for example, a recording button 9A 'from the time when the elapsed time T _R, the time t _3' is the time t ₂ which is operated when the time t ₂ 'to time T _B content of obtained by high-speed imaging of high rate of the captured image data, the recording and the recording medium 7 as the image data of four times the normal rate time T _R min of time T _B, the time t ₂ ', the time T _R picked up by the microphone 8 The recording of the minute audio data to the recording medium 7 ends at time t ₃ ′.

Here, in the high-speed imaging mode, timing mode the timing of the operation of the recording button 9A, is a mode indicating whether the timing of the beginning of image data for high-rate time T _B min, or the timing of the end Can be set.

As shown in FIG. 2, a timing mode in which the operation timing of the recording button 9 </ _b > A is the leading timing of high-rate captured image data for time TB is referred to as “from here” mode. Further, as shown in FIG. 3, the timing of the operation of the recording button 9A, the timing mode to the timing of the end of the captured image data of a high rate of time T _B min, referred to as "far" mode.

At the same time, it is operated when setting to a voice-in mode for recording voice data.

The return button B ₃₃ is operated to close the voice recording setting screen of FIG. 7 and return to the setting item selection screen of FIG.

Setting mark M ₃₁ represents whether audio recording mode is set to any of the audio cutting mode, or a voice print mode.

That is, when the voice recording mode is set to the voice cut mode, the setting mark M ₃₁ is displayed on the left side of the “off” button B ₃₁ as shown in FIG. When the voice recording mode is set to the voice on mode, the setting mark M ₃₁ is displayed on the left side of the “ON” button B ₃₂ .

FIG. 8 shows an audio recording setting screen when the “ON” button B ₃₂ in FIG. 7 is operated.

When the voice recording mode is set to the voice cut mode, as shown in FIG. 7, the voice record setting screen in which the setting mark M ₃₁ is displayed on the left side of the “OFF” button B ₃₁ is displayed. However, when the “ON” button B ₃₂ is operated on the voice recording setting screen of FIG. 7, the setting mark M ₃₁ is displayed on the left side of the “OFF” button B _{31 on} the voice recording setting screen, as shown in FIG. Instead, it is displayed on the left side of the “ON” button B ₃₂ and the return button B ₃₃ is changed to an “OK” button B ₃₄ .

Further, on the audio recording setting screen, in response to the operation of the “ON” button B ₃₂ , an icon I ₃₁ as information indicating that the audio recording mode is set to the audio input mode, and a message MS ₃₁ are displayed. Is displayed.

That is, on the audio recording setting screen, an icon I ₃₁ consisting of a microphone-shaped GUI and a note-shaped GUI is displayed on the upper right, and a message MS ₃₁ is displayed in the middle of the message “Save Slow Movie”. "You can record audio during" is displayed.

According to the icon I ₃₁ and the message MS ₃₁ as described above, the user can recognize that sound is recorded together with an image in smooth slow recording.

  When the timing mode or the voice recording mode is set (changed), the microprocessor 10 (FIG. 1) stores the mode information indicating the set timing mode or the voice recording mode in the nonvolatile memory 20. .

  Thereby, even when the camera of FIG. 1 is turned off, the timing mode and the sound recording mode set when the power is turned off are maintained when the power is turned on next time.

  Next, FIG. 9 shows a smooth slow recording function screen when the audio recording mode is set to the voice-in mode.

Here, the smooth slow recording function screen of FIG. 5 described above is a smooth slow recording function screen when the voice recording mode is set to the voice cut mode, and the voice recording mode is set to the voice on mode. 9 smooth slow recording function screen only in that the icon I ₁₃ is displayed is different from the smooth slow recording function screen of FIG. 5 the audio recording mode is set to the voice cutting mode.

The icon I ₁₃ is the same icon as the icon I _{31 in} FIG. 8, that is, an icon composed of a microphone-shaped GUI and a note-shaped GUI, and represents that the voice recording mode is the voice-on mode.

When the voice recording mode is set to the voice on mode, the icon I ₁₃ is displayed on the slow recording function screen as shown in FIG. 9, and the voice recording mode is set to the voice cut mode. If it is, the slow-motion recording function screen is not displayed from the lick as shown in FIG.

Therefore, the user records the sound (recording) together with the image recording (recording) in the sound recording mode, that is, the smooth slow recording, depending on whether or not the icon I ₁₃ is displayed on the smooth slow recording function screen. Or it can be recognized that this is not done.

As described above, when the voice recording mode is set to the voice-on mode, the icon I ₁₃ is displayed on the slow-motion recording function screen, but this icon I ₁₃ is displayed when the voice is not being recorded. For example, it is displayed in a blinking state.

Then, the smooth slow recording function screen, with the icons I ₁₃ is displayed, when the record button 9A is operated, as described in FIGS. 2 and 3, the audio data captured by the microphone 8 is recorded Recorded on the medium 7.

  FIG. 10 shows a smooth slow recording function screen when audio data is being recorded.

  When the imaging mode becomes the high-speed imaging mode, the microprocessor 10 reads the mode information from the nonvolatile memory 20, and recognizes the current audio recording mode and timing mode based on the mode information. In step S11, the microprocessor 10 controls the OSD circuit 11 so as to display a smooth slow recording function screen corresponding to the current audio recording mode and timing mode.

  Under the control of the microprocessor 10, the OSD circuit 11 generates OSD image data of a smooth slow recording function screen corresponding to the current audio recording mode and timing mode, and supplies the OSD image data to the touch panel 14 via the superimposing circuit 12. Thus, on the touch panel 14, a smooth slow recording function screen corresponding to the current audio recording mode and timing mode is displayed.

That is, for example, voice recording mode, a voice cutting mode, timing mode, when a mode "from here", as shown in FIG. 5, and icons I ₁₃ (Figure 9 representing the voice print mode 10) no smooth slow recording function screen icons I ₁₁ representing the mode "from here" exists is displayed.

Further, for example, when the voice recording mode is the voice entering mode and the timing mode is the “from here” mode, as shown in FIG. 9, the icon I ₁₃ indicating the voice entering mode and “here smooth slow recording function screen icons I ₁₁ representing the "mode from the present is displayed.

  Thereafter, the process proceeds from step S11 to step S12, and the microprocessor 10 determines whether or not the timing mode is the “to here” mode. If it is determined in step S12 that the timing mode is not the “to here” mode, that is, if the timing mode is the “from here” mode, the process skips step S13 and proceeds to step S14.

  If it is determined in step S12 that the timing mode is the “to here” mode, the process proceeds to step S13, and the microprocessor 10 performs the camera image processing circuit 3 so as to perform high-speed imaging repetition processing. To control.

  In step S17, the microprocessor 10 determines whether or not the recording button 9A (FIG. 1) has been operated.

  If it is determined in step S17 that the record button 9A has not been operated, the process skips step S18, returns to step S14, and thereafter repeats the same process.

  If it is determined in step S17 that the recording button 9A has been operated, the process proceeds to step S18, and a smooth slow recording process to be described later is performed. Then, after the smooth slow recording process is completed, the process returns to step S14, and the same process is repeated thereafter.

On the other hand, if it is determined in step S14 that the “end” button B ₁₁ (FIGS. 5 and 9) has been operated, the microprocessor 10 sets the imaging mode to the normal imaging mode and performs processing in the high-speed imaging mode. finish.
