Abstract: An upper electrode used for a substrate processing apparatus using plasma is provided. The upper electrode includes a bottom surface including a center region and an edge region having a ring shape and surrounding the center region, a first protrusion portion protruding toward plasma from the edge region and having a ring shape, wherein the first protrusion portion includes a first apex corresponding to a radial local maximum point toward the plasma, and a first distance, which is a radial-direction distance between the first apex and a center axis of the upper electrode, is greater than a radius of a substrate.

Abstract: A method and apparatus for generating a high-resolution digital zoom image may obtain a raw image captured by an image sensor from the image sensor, obtain an RGB image corresponding to the raw image, separate a luminance component and a chrominance component from the RGB image, extract a first feature of the RGB image, of which color information is enhanced, by applying the chrominance component to a first neural network, extract a second feature of the RGB image, of which texture information is enhanced, by applying the raw image and the luminance component to a second neural network, and generate the high-resolution digital zoom image, which corresponds to the RGB image, by upscaling the color information and the texture information based on the first feature or the second feature.

Abstract: A processor-implemented method with super resolution includes: determining a direction type of an input image based on a gradient of the input image; acquiring a first intermediate image that is a super-resolution image corresponding to the input image based on a residual look-up table (LUT) corresponding to a kernel set mapped to the determined direction type; determining a LUT strength map of the input image based on the gradient of the input image and a preset tuning parameter; and generating an output image that is a super-resolution image of the input image based on the LUT strength map and the first intermediate image.

Abstract: A processor-implemented method includes generating an adjusted reference patch by adjusting a position of a reference patch in a reference image based on a pixel value of a ground truth (GT) patch of a GT image and a pixel value of the reference patch, wherein the GT patch corresponds to a specific region of an input image; generating a super-resolution (SR) image of the input image using a SR model provided an input that is based on the generated adjusted reference patch; and training the SR model based on the SR image and the GT image.
