Abstract: Disclosed are a camera module and an electronic device. The camera module includes a first lens, a second lens, and a photosensitive chip that are coaxially disposed in a first direction sequentially, where a first reflective film is disposed on a side of the first lens away from the second lens; a second reflective film is disposed on a side of the first lens close to the second lens; the second lens is entirely provided with a third reflective film on a side close to the photosensitive chip; a light-transmitting hole is provided on a middle part of the side of the second lens close to the photosensitive chip; and at least two adjusting lenses are disposed in the light-transmitting hole.

Abstract: A preparation method of a low-cost passivated contact full-back electrode solar cell includes: performing alkali polishing on a Si wafer; performing RCA cleaning and HF cleaning; growing a tunnel SiOx film layer, an in-situ doped amorphous Si film layer, and a texturing mask layer on the back of the Si wafer; performing annealing activation on the amorphous Si film layer to form a polycrystalline Si film layer; etching the texturing mask layer; performing double-sided texturing on the Si wafer; performing HF cleaning to remove the texturing mask layer; depositing an AlOx film on the front and back of the Si wafer; depositing a SiNx passivation film on the front and back of the Si wafer; ablating a part of the AlOx film and a part of the SiNx passivation film on the back of the Si wafer; and performing screen-printing and sintering on the back of the Si wafer.

Abstract: An image processing method includes: obtaining a first image photographed by each of N color cameras in the M color cameras; obtaining, for each first image, luminance values of at least a part of pixels in the first image; and increasing brightness of a target image by using the obtained luminance values, and using the target image with increased brightness as an image photographed by the under-screen camera assembly, the target image being the first image photographed by one of the N color cameras, where both M and N are integers greater than or equal to 2, and N is less than or equal to M.

Abstract: An image processing method includes: obtaining a first image photographed by each of N1 first cameras in the M1 first cameras and a second image photographed by each of N2 second cameras in the M2 second cameras; obtaining luminance values of at least a part of pixels in the first image and luminance values of at least a part of pixels in the second image for each first image and each second image; and increasing luminance of a target image based on obtained luminance values, and using, as a photographed image of the under-display camera assembly, a target image obtained after the luminance is increased. M1, N1, M2, and N2 are all integers greater than or equal to 1.

Abstract: A camera assembly includes: a hollow lens base, having a first and second accommodation chamber from up to down, an inner diameter of the first accommodation chamber being smaller than that of the second accommodation chamber, the second accommodation chamber being configured to accommodate an image sensor, the top of the first accommodation chamber having an opening; a lens cone, arranged on the lens base and having an extension member at the bottom, an inner diameter of the extension member being greater than an outer diameter of a side wall of the first accommodation chamber; and a driving motor, connected to the lens cone and configured to control the lens cone to move reciprocally in a predetermined direction. During the reciprocal movement, an end surface of the extension member is always located below a top surface of the first accommodation chamber where the opening is provided.
