    Abstract: A diffusion lens includes a concave first lens surface, a convex second lens surface such that part of light incident on the first lens surface is output from the second lens surface, a side surface extending from a periphery of the second lens surface in a vertical direction of the diffusion lens such that part of the rest of the light incident on the first lens surface is output from the side surface, and a bottom surface extending from a periphery of the first lens surface in a horizontal direction of the diffusion lens to meet a periphery of the side surface. Rates of change of the first and second lens surfaces have the same sign. A pattern is formed on the side surface and the bottom surface to diffuse the light through the side surface and diffuse the light reflected by the bottom surface.

    CPC classification number: H04N19/184

    Abstract: Provided are an image processing device and an operating method of the image processing device. An image processing device includes a multimedia intellectual property (IP) configured to process image data for pixels constituting one frame image, and an encoder configured to generate compressed data by performing compression on the image data, wherein the encoder includes a compression module and a first buffer. The compression module is configured to generate first compressed data by performing compression on the first image data including a most significant bit (MSB) of the image data, and the first buffer is configured to store second image data containing a least significant bit (LSB) of the image data, in order to skip compression for the second image data.

    Abstract: A video encoding method of estimating a motion vector of a current block in a current frame includes identifying a reference block in a reference frame, a first location of the current block within the current frame corresponding to a second location of the reference block within the reference frame, setting a search range in the reference frame, searching for candidate blocks from the search range of the reference frame, each of the candidate blocks satisfying a corresponding first motion estimation criterion of first motion estimation criteria, searching for a prediction block from among the candidate blocks, the prediction block satisfying a second motion estimation criterion, estimating, as the motion vector of the current block, a motion vector corresponding to a displacement between the reference block and the prediction block, and encoding the current block based on the estimated motion vector.
