The embodiment of the utility model provides a camera device, which comprises a light-transmitting body, a light-transmitting lens and a light-transmitting lens, under the condition that the light shielding body is attached to the light transmitting body, the light shielding body is located on the light entering face of the light transmitting body and used for restraining light rays entering the light transmitting body from the target angle; and the sensor is arranged on the light emitting side of the light-transmitting body and is used for receiving the light passing through the light-transmitting body and imaging. Therefore, the problem of poor imaging effect of the camera device in the prior art can be solved, and the technical effect of improving the imaging effect of the camera device is further achieved.

The application discloses a small cloud detection and identification camera and satellite, and relates to optical measurement and metrology. The application comprises a lens group, a pre-filter arranged on the image side of the lens group, the pre-filter being a double-channel narrow-pass filter, a color detector arranged on the other side of the pre-filter, the color detector being a surface array imaging detector adopting a Bayer filter, a processing circuit in communication connection with the color detector, used for receiving detection data of the color detector and performing image identification, and a support structure provided with an inner cavity matched with the support structure, the lens group, the pre-filter, the color detector and the processing circuit, wherein the lens group, the pre-filter, the color detector and the processing circuit are arranged in the inner cavity, so that the problem that the existing cloud judgment method and load cannot completely meet the on-orbit use requirement of high-resolution remote sensing imaging satellites is solved.

The application relates to the technical field of mini-LED, and provides a three-dimensional reflecting sheet for reducing mini-LED backlight halos, which comprises a plurality of integrally connected reflecting covers, each reflecting cover comprising: a reflecting bottom surface, the center of which is provided with a relief hole; a reflecting side surface, which is connected to the edge of the reflecting bottom surface along the circumference of the reflecting bottom surface, and which, together with the reflecting bottom surface, surrounds a cup-shaped cover body space; the adjacent reflecting covers are connected through the reflecting side surfaces, and the reflecting bottom surfaces and the reflecting side surfaces are integrally connected, so that the three-dimensional reflecting sheet is formed into an integral structure; the three-dimensional reflecting sheet can simultaneously process light rays from multiple directions, can block light beams from entering other control areas through the reflecting side surfaces, can reduce light leakage, and can reduce halos.
