    摘要: Disclosed is a method of operating a storage device which includes a storage controller and a non-volatile memory device. The method includes providing a first request indicating a word line sequential read operation of a target memory block of the non-volatile memory device, providing first word line read data corresponding to memory cells of a first word line of the target memory block based on the first request, providing second word line read data corresponding to memory cells of a second word line of the target memory block based on the first request, the second word line being adjacent to the first word line, calculating a first word line gap value based on the first word line read data and the second word line read data, and performing a first reliability operation of the target memory block based on the first word line gap value.

    摘要: A method and apparatus for, in a video encoding and decoding procedure, selecting a candidate motion vector of a current block from a motion vector candidate list of the current block, determining a motion vector of the current block by performing a motion search based on the candidate motion vector, performing motion compensation by using the determined motion vector of the current block, and applying local luminance compensation to the current block based on whether the local luminance compensation is to be applied to the current block, wherein a cost function used for performing the motion search is determined based on whether the local luminance compensation is to be applied to the current block.
