BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera-integrated magnetic recording and reproducing apparatus that automatically sets the recording speed depending on the video tape and recording mode used.

0002

[Prior Art] In recent years, camera-integrated magnetic recording and reproducing devices (
Hereinafter, it will be abbreviated as movie. ) as the image quality and sound quality continue to improve.
Compared to the image quality of standard recording speed (hereinafter referred to as SP) in normal recording mode (hereinafter referred to as VHS mode), the recording speed (3 times faster) in high quality recording mode (hereinafter referred to as S-VHS mode) (hereinafter abbreviated as EP) has been getting better year by year.

[0003] Conventional movies will be explained below. FIG. 3 shows the structure of a conventional movie. In FIG. 3, 31 is a high-quality recording tape (hereinafter referred to as S-VHS).
Abbreviated as tape. ) and normal recording tapes (hereinafter abbreviated as VHS tapes). Reference numeral 32 denotes fixed recording mode switching means for selecting between the S-VHS mode and the VHS mode. 33 is SP and E
This is a fixed recording speed switching means for selecting P. 34
is a high-quality tape judgment command outputted from the high-quality tape discrimination means 31, a recording mode command outputted from the fixed recording mode switching means 32, and a recording speed command outputted from the fixed recording speed switching means 33. This is a system control means that inputs and determines recording specifications. Reference numeral 35 denotes a recording mode setting means for inputting the recording mode determination command outputted from the system control means 34 and setting the recording mode. Reference numeral 36 denotes a recording speed setting means for inputting a recording speed determination command outputted from the system control means 34 and setting the recording speed. Reference numeral 37 denotes a system display means for inputting the recording specification determination command outputted from the system control means 34 and displaying the current recording specification.

[0004] The operation of the movie of the above-mentioned components will be explained below. First, the fixed recording mode switching means 32 is operated to select a recording mode, and the fixed recording speed switching means 33 is operated to select a recording speed. Then, the system control means 34 makes a comprehensive judgment including the high-quality tape judgment command outputted from the high-quality tape judgment means 31, and determines the recording specifications. Furthermore, the system control means 34 outputs a recording mode determination command to the recording mode setting means 35 to set the video circuit section to a predetermined recording mode. The recording speed setting means 3 also sends a recording speed determination command to the recording speed setting means 3.
6, and set it to a predetermined recording speed. Now, if the S-VHS mode is set to EP and the videotape is an S-VHS tape,
Recording specifications are determined by the EP in S-VHS mode. Furthermore, if the video tape is a VHS tape with the same settings as above, the recording specifications will be determined by the EP in VHS mode. Below, the recording specifications are listed using the same operation (Table 1
)become that way. Further, the system display means 3 receives the recording specification determination command outputted from the system control means 34.
7 displays the recording mode and recording speed in the viewfinder or on the liquid crystal panel so that the current recording specifications can be clearly understood.

[0005]

[Table 1]

[0006]

However, in the conventional configuration, it is troublesome to check the recording specifications each time depending on the type of video tape to be used. For example, if you are trying to shoot high-quality video using an S-VHS tape and the fixed screen mode switching means 32 remains switched to VHS mode, it is clear from (Table 1) that Thus, even though an S-VHS tape is used, it is actually recorded in VHS mode. Furthermore, a certain user A is S
-When shooting in VHS mode, even if you record in EP
Although the recording specifications were decided based on the judgment that EP is more advantageous in S-VHS mode because it can record at the same high quality as P and the recording time is longer, another user B recorded the video. If the user A operates the fixed recording speed switching means 33 to change the setting to SP at that time, it is conceivable that the user A may start recording at SP without noticing it at all.

The present invention solves the above problems by determining the type of videotape when turning on the power or inserting a videotape, and in the case of an S-VHS tape, EP is played in S-VHS mode. For VHS tapes, VH
By initially setting SP in S mode and having non-fixed recording mode switching means and non-fixed recording speed switching means, it provides a movie in which subsequent recording specifications can be freely reset like conventional movies. The purpose is to Furthermore, when the recording mode has already been determined by the fixed recording mode switching means, the type of videotape is determined and the S-VHS tape is initialized to EP in S-VHS mode and SP in VHS mode. On the other hand, when playing a VHS tape, select S-
The purpose is to provide a movie in which the SP can be initialized in both VHS mode and VHS mode, and the subsequent recording specifications can be freely reset in the same way as conventional movies by having a non-fixed recording speed switching means. shall be.

[0008]

[Means for Solving the Problems] In order to achieve this object, the camera-integrated magnetic recording and reproducing device of the present invention includes a high-quality tape discrimination means for discriminating between a high-quality recording tape and a normal recording tape, and A high-quality tape judgment command output from the high-quality tape discrimination means is input, and if the tape is a high-quality recording tape, the high-quality recording specification and triple-speed recording specification are selected, while if the tape is a normal recording tape, the a system control means for selecting a normal recording specification and a standard recording speed specification; a recording mode setting means for inputting a recording mode determination command output from the system control means and setting the high-quality recording mode and the normal recording mode, respectively; , a recording speed setting means for inputting a recording speed determination command output from the system control means and setting the recording speed to triple recording speed and a recording standard speed, and inputting a recording specification determination command output from the system control means; It has a configuration including a system display means for displaying the currently set recording specifications. Furthermore, when the high-quality recording specifications and the normal recording specifications have been set in advance by the fixed recording mode switching means, the system control means sets the high-quality recording mode by the fixed recording mode switching means, and the high-definition recording tape Time is recording 3
On the other hand, when using a normal recording tape, select the standard recording speed specification, and if the fixed recording mode switching means sets the normal recording mode and the normal recording specification is selected, the normal recording speed is selected even when using a high-quality recording tape. It has a configuration that allows you to select the standard recording speed specification even when using tape.

[0009]

[Operation] With this configuration, when turning on the power or inserting a videotape, the type of videotape is determined, and in the case of an S-VHS tape, the recording speed is set to EP in S-VHS mode. In VHS mode, the recording speed is initially set to SP, and as with conventional movies, subsequent recording specifications can be freely reset, so you can change the videotape type, recording mode, and recording speed. You can start recording under the same conditions every time without worrying about settings.
