In particular, the present invention relates to a video signal recording device that can capture images of incidents that occur suddenly.

0002

2. Description of the Related Art Recording a sudden incident as a video is important because it allows the situation and atmosphere of the scene to be clearly recorded. Therefore, there is a need for a recording device that can quickly record video images of incidents that occur suddenly.

[0003] Conventional camera-integrated VTRs are provided with an auto lock key mode, a quick rec mode, etc. in order to enable the above-mentioned quick video recording.

[0004] The above-mentioned auto lock key mode sets all functions of the camera section to auto mode when power is supplied, that is, when the power switch is turned on and the camera mode is selected. .

[0005] Furthermore, in the above-mentioned quick record mode, when the power switch is turned on and the camera mode is selected, all functions of the camera section are set to auto mode and recording operation is started. be.

[0006]

[Problems to be Solved by the Invention] The above-mentioned conventional techniques each have the following problems. (1) About auto-lock key mode To enter auto-lock key mode, the prerequisite is that the power switch is turned on and the camera mode is selected as described above.If this condition is not met, cannot be set to auto-lock key mode. That is, the automatic lock key mode cannot be set when the power switch is turned off or when the VTR mode is selected instead of the camera mode. Furthermore, even if the auto-lock key mode was entered, the recording operation would not start.

[0007] Therefore, in this auto-lock key mode, it is practically very difficult to quickly record an incident that suddenly occurs.

(2) About Quick Rec Mode In order to enter Quick Rec Mode, the prerequisite is that the power switch is turned on and camera mode is selected, similar to the above-mentioned auto lock key mode. If the conditions are not met, Quick Rec mode cannot be used.

Although the recording operation starts when the quick record mode is entered, if a key operation is performed while the quick record mode is set, the key input is accepted. Therefore, if the user performs an incorrect key operation, there is no guarantee that a correct image will be obtained.

[0010] Particularly when shooting in a very crowded location, there is a possibility that an incorrect key operation may be performed, and in this case, it is necessary to play back the image to see if it has been obtained correctly. It was something I couldn't understand.

[0011] Accordingly, an object of the present invention is to provide a video signal recording device that can reliably record sudden incidents quickly.
