The invention relates to the technical field of image processing, and discloses a step exposure and optical coating combined method and system, and the method comprises the steps: collecting instrument panel image information by a camera, calculating a refresh frequency according to a gray difference, and automatically adjusting the opening and closing time of a shutter according to the refresh frequency. The shutter opening and closing time of the camera is kept synchronous with the refresh frequency of the instrument panel; image information of the instrument panel of the instrument is collected again, whether an optical filter in the camera needs to be adjusted or not is judged, and when it is judged that the optical filter needs to be adjusted, the light transmittance of the optical filter is adjusted according to the light intensity; continuously acquiring image information of the instrument panel, and judging whether the exposure time of the camera needs to be adjusted or not; and acquiring the information of the environment where the camera is located, and adjusting the exposure time of the camera. According to the invention, the camera can obtain accurate and clear image data under various illumination conditions.

The invention relates to the field of ship electromechanical monitoring, in particular to a remote control operation unit suitable for ship electromechanical monitoring, which comprises a core board, a remote control operation unit body, a remote control operation unit mainboard and a remote control operation unit panel, and supports various input and output of key switching value, gear switching value, analog quantity, CAN communication data and the like; a key circuit board is adopted to receive key signal input; an indicating lamp is arranged on the panel; and the shell is made of an aluminum alloy material. The size and the interface are standardized, so that the standardization level of equipment is improved, and the types and the number of spare parts are reduced; compared with an existing product, the depth is small, and the design is flatter; the weight is light, the corrosion resistance is high, and the service life is long; the brightness of the panel is ensured through the adjustable panel backlight at night; the front surface is free of any threaded hole, the layout is neat, and the aesthetic degree is high.

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.
