Description

Monitor

The present invention relates to a monitor, and more particularly to a monitor that enhances the sharpness of captured images.

Surveillance cameras are used in a wide range of applications. In the factory premises, dormitories, shops, buildings or community homes, entrances and exits, and other places where surveillance is required, or inaccessible places, the surveillance cameras can be used to record the current situation for future use. Use for tracing, depositing, etc. In this way, the unscrupulous elements can be deterred, and the unscrupulous will not dare to conduct illegal activities, thereby avoiding the occurrence of things that endanger the law and order.

In general, the camera monitors the built-in light source (light-emitting diode of visible light or LED of infrared light) to enable the surveillance camera to monitor when the light source is insufficient (indoor or nighttime). However, if the built-in light source of the surveillance camera is not properly designed, some of the built-in light sources may be blocked by the fuselage and cannot be irradiated to objects in the monitoring area. Even the built-in light source of the surveillance camera may be caused by light leakage through the inside of the fuselage or reflected to the photographic lens. The phenomena created by these improper designs can reduce the sharpness of the picture captured by the surveillance camera. Therefore, it is necessary to develop a monitor to enhance the sharpness of the image captured by the monitor.

The present invention relates to a monitor for improving the sharpness of an image captured by a monitor.

The reflector has a first reflecting surface. The reflector surrounds the photographic lens module, and the first reflective surface faces the light source module, so that the light of the light source module is reflected to the monitoring area.

The monitor disclosed in the present invention comprises a casing, a photographic lens module, A light source module and a reflector. The photographic lens module is located in the housing for capturing a monitoring area. The light source module is located inside the housing. The light source module includes at least one light emitting element. The reflector is located within the housing. The reflector has at least one first reflective surface. The at least one first reflecting surface faces the at least one illuminating element and surrounds the at least one illuminating element for reflecting the light of the at least one illuminating element to the monitoring area.

According to the monitor disclosed in the above, the first reflecting surface of the reflecting member is disposed on one side of the light emitting element, so that the first reflecting surface projects the lateral light of the light emitting element to the monitoring area. In this way, the monitor is provided with a reflector to help improve the intensity and uniformity of the light field in the monitoring area of the photographic lens module, thereby increasing the sharpness of the image captured by the photographic lens module.
