The invention relates to an electrophotographic photoreceptor, a process cartridge, and an image forming apparatus. The electrophotographic photoreceptor includes a conductive substrate and a photosensitive layer of a single-layer type disposed on the conductive substrate. The photosensitive layer has an absorption coefficient of 0.008 or less at a wavelength of 1000 nm and contains a binder resin, a charge generating material, an electron transporting material, and a hole transporting material. The charge generating material is at least one selected from a hydroxygallium phthalocyanine pigment and a chlorogallium phthalocyanine pigment and is contained in an amount of 0.9% by weight or more and 1.8% by weight or less relative to the binder resin.

The invention relates to an anti-reflection film for a visible light wave band and a design method and a preparation method thereof. The anti-reflection film comprises a substrate which is white glass; the thin film stack is formed on at least one side of the substrate, the thin film stack is formed by stacking at least seven thin film layers, the thin film layers are selected from a low-refractive-index material and a high-refractive-index material of a visible light wave band, and the thin film stack is integrally formed in a mode that the low-refractive-index material and the high-refractive-index material are alternately combined; wherein the physical thickness sequence of all the thin film layers of the thin film stack is a non-periodic sequence. The reflectivity is less than or equal to 0.5% and the transmittance is more than or equal to 98% in the whole visible light wave band.

An image processing method and device, a computer readable storage medium and a terminal, the method comprising: acquiring F frames of first images, F being an integer greater than 1; inputting the F frames of first images into a neural network model trained in advance to obtain fusion parameters output by the neural network model, the fusion parameters comprising enhancement parameters and weight parameters, wherein the enhancement parameters comprise a mapping vector corresponding to each pixel point of each frame of first image, and the weight parameters comprise a weight value corresponding to each pixel point of each frame of first image; performing enhancement processing on the F frames of first images according to at least the enhancement parameters to obtain F frames of second images; and performing fusion processing on the F frames of second images according to the weight parameters to obtain a target image. Through the scheme provided in the present application, multiple frames of images can be fused efficiently to obtain a high-quality image.
