    Abstract: Disclosed is a technology of preferentially forming an ohmic contact layer and a conductor layer before separating a nanorod light emitting diode (LED) from a substrate, thereby being capable of omitting a heat treatment process performed at high temperature after aligning the nanorod LED, and, accordingly, preventing electrical short while maximizing the quantum efficiency of the nanorod LED and increasing a selection range of a material constituting a light emitting diode (LED) display. More particularly, the nanorod LED includes a first semiconductor layer; a multi-quantum well structure layer; a second semiconductor layer; and a conductor layer formed on at least one semiconductor layer of the first semiconductor layer and the second semiconductor layer, wherein a length and shape of the conductor layer are controlled such that the multi-quantum well structure layer is disposed between two electrodes of the electrode pattern on which the conductor layer is to be aligned.

    Abstract: Disclosed is an image processing method and apparatus. The image processing method includes receiving an image including frames captured over time in a light environment including an alternating current (AC) light, extracting AC pixels corresponding to the AC light from pixels in the image, estimating visual spaces of the AC pixels based on values of the AC pixels in the frames, estimating information of the AC light included in the image based on the visual spaces, and processing the image based on the information of the AC light.

    Abstract: Disclosed is an erasure-based Reed-Solomon code soft-decision decoding method and device, capable of reducing a decoding time while minimizing the effect on error correction performance. The Reed-Solomon code soft-decision decoding device includes an erasure control circuit configured to determine whether a number of errors in a codeword is odd or even, and to provide a key equation solver circuit with a first erasure pattern or a second erasure pattern according to a result of the determining when a decoding failure is detected by a decoding error detection circuit, the first erasure pattern being provided when the number of errors is odd, the second erasure pattern being provided when the number of errors is even.
