Car antenna

This application discloses an image processing method and apparatus, and relates to the field of image processing technologies, to help optimize a color, a contrast, or a dynamic range of an image, so that an optimized image can be more objective, and robustness is improved. The method is applied to a terminal including a first camera and a second camera. The method includes: when an ISO of the first camera in a current photographing environment is greater than a first threshold, capturing a first image for a first scenario in the current photographing environment; capturing a second image for the first scenario; and optimizing the first image based on the second image to obtain a third image. An image style of the second image is better than that of the first image.

Image processing method and apparatus

Provided are a phase shifter, a preparation method thereof, and an antenna. The phase shifter includes at least one phase shifting unit, and the phase shifting unit includes a microstrip line, a photo-dielectric layer, a ground electrode, and at least one light guiding structure; the microstrip line is located on a side of the photo-dielectric layer, and the ground electrode is located on a side of the photo-dielectric layer facing away from the microstrip line; the light-guiding structure at least partially overlaps the photo-dielectric layer, and the light-guiding structure is configured to guide light into the photo-dielectric layer.

Antenna including at least one microstrip line phase shifting unit having a photo-dielectric layer and a light guiding structure configured to guide light into the photo-dielectric layer

Provided are a liquid crystal antenna, a manufacturing method thereof and a communication device having the liquid crystal antenna. The liquid crystal antenna includes a first metal electrode, a second metal electrode, a third metal electrode, at least two oppositely arranged substrates, and a liquid crystal layer located between the two oppositely arranged substrates. The two oppositely arranged substrates each include a light transmission area. The first metal electrode, the second metal electrode and the third metal electrode within the light transmission area each are a hollowed-out structure, and the light transmission area can be used to test a cell thickness of the liquid crystal cell. Since the cell thickness can be measured, other process parameters can be matched and adjusted, so that a mass production yield of the liquid crystal antennas is improved.
