The application relates to the technical field of camera equipment, and discloses an underwater monitor which comprises a shell, a display screen and a cover plate. An opening is formed in the shell. A processor is fixedly arranged in the shell. A connecting line is connected to the shell and electrically connected to the processor. The display screen is located in the opening and fixedly connected to the shell. A light intensity sensor is arranged at the edge of the opening. The display screen and the light intensity sensor are electrically connected to the processor. The cover plate is arranged on the opening and sealingly connected to the edge of the opening. The automation degree of the backlight adjustment (brightness adjustment) of the display screen is improved, the manual operation steps are reduced, the labor intensity is reduced, the backlight adjustment of the display screen is more convenient, and the operation is simple.

The present application provides a kind of face exposure adjustment method, comprising: S1, obtaining face region coordinate;S2, face coordinate processing: including: excluding face: select the main face as the face that needs to be carried out face exposure;Adjust face size: the region of doing face exposure is cropped, ensure that the region of face exposure is all face without background;Face anti-shake: prevent face shaking and lead to exposure position inaccuracy;S3, calculate the brightness of face region and picture: according to the brightness histogram of face region and whole image respectively, through the proportion of over-bright point, over-dark point and normal brightness point of brightness histogram, the brightness of face and whole picture is calculated;S4, obtain basic brightness: obtain basic target brightness according to current EV and EV table;S5, calculate target brightness: according to the brightness of whole image, obtain the final face target brightness;S6, brightness takes effect: according to face target brightness, image brightness is exposed to appropriate brightness.

The utility model discloses a mining explosion-proof support illuminating lamp, which comprises a shell, a lamp holder, a lamp holder, a lamp holder, a lamp holder, a lamp holder, a lamp holder, a lamp holder, a lamp holder and a lamp holder, the shell is internally provided with a mounting cavity, and the mounting support is provided with at least one mounting hole; the light source plate is arranged in the mounting cavity, and a plurality of LED lamp beads are arranged on the light source plate; the lens is arranged on one side of the light source plate; the reflecting cover is arranged on the side, away from the light source plate, of the lens, a glass plate is arranged on the reflecting cover, a plurality of screws are arranged on the reflecting cover, and the screws sequentially penetrate through the reflecting cover, the lens and the light source plate to be connected to the shell. Compared with the prior art, the mining explosion-proof roadway lamp can solve the problems that a low-power illuminating lamp is adopted in an existing mining explosion-proof roadway, the illumination intensity in the roadway is possibly insufficient, work is affected, and if a high-power illuminating lamp is adopted, the mining explosion-proof roadway lamp generates high temperature, ignites gas, is poor in safety and causes electric energy waste.
