Description

[Detailed Description of the Invention] ■. Background Technical Field of the Invention The present invention relates to a shooting monitor camera and device for monitoring shooting operations in combination with a gun, and particularly for use in combination with a shotgun, rifle, etc. in the field. The present invention relates to a device for measuring the position of a shooter's shot during hunting, clay shooting, etc.

Prior art and its problems Conventionally, shooting skills have been acquired by either practicing at a shooting range with a coach standing behind or to the side of the shooter, or by gaining experience and becoming proficient on their own.

However, compared to situations such as rifle shooting competitions where the target is stationary and you can actually see the target with bullet holes, hunting with a shotgun or rifle in the field, clay pigeon shooting, etc. When hitting moving targets, such as skeet shooting, trap shooting, and running hole shooting, determine how accurately the shooter is aiming at the target and how far the shot is horizontally or vertically off target. It's difficult.

However, in order to improve your shooting skills, it is important to know your own shooting operations well and time your shots appropriately. Being able to observe how they hit and miss their targets is very convenient for both shooters and instructors.

Of course, the shooter himself knows how his gun will move right before or at the moment of firing. However, it is not possible to accurately recall or memorize the movement, so a device is needed to monitor the actual position of the gun or bullet relative to the target and reproduce it on a display. In this way, shooters and instructors can visually analyze the shooting process using a television receiver, and identify any shortcomings or habits in the shooter's shooting habits.

The present inventor has already disclosed a device for determining the position of a bullet in clay shooting against a moving target, and has filed a patent application No. 58-21509.
In No. 4, only the imaging lens barrel was separated from the television camera, and this was fixed in a suitable position on the gun with the optical axis of the imaging lens barrel oriented parallel to the axial center line of the gun barrel. , a bullet position determination device for clay pigeon shooting, which is optically connected via the remaining photoelectric conversion element and imaging lens barrel of the television camera, and the television camera is connected to a video tape recorder and a television receiver by an electric cord. of.

Japanese Patent Application No. 58-215095 discloses a small television camera mainly equipped with an imaging lens barrel and a solid-state imaging device.
For clay shooting, the imaging lens barrel is fixed in place on the gun with its optical axis oriented parallel to the axis of the gun barrel, and the small television camera, video tape recorder, and television receiver are connected by electrical cords. Special application for bullet position determination device in 1986
No. 46044 discloses an imaging means fixed to the barrel of a gun so that the optical axis extends substantially parallel to the axial line of the barrel, and for optically photographing a scene on the optical axis; A shooting monitor camera, which is combined with camera means for converting the above-mentioned scene into a video signal, and transmitting means for wirelessly transmitting the video signal of the camera means, and is characterized in that it monitors the firing position of a gun. Furthermore, they have proposed a shooting monitoring device for monitoring the shooting position of a gun, which is equipped with the shooting monitoring camera described above, and a video means having a receiving means, or a display means for reproducing the photographed scene.

However, among these applications, Japanese Patent Application No. 58-215094
No. 58-215095 states that a television receiver is an essential component, and it is preferable to remove one television receiver and carry a video device when hunting outdoors. There is no need to include a television receiver as a reprint is sufficient.

Furthermore, in Japanese Patent Application No. 60-46044, the video signal from the camera means is wirelessly transmitted to the video means, but in outdoor hunting, the video means is often damaged in a certain place, as hunting is often done over long distances in a short time. However, it is difficult to wirelessly transmit the video signal from the camera means.
