Abstract: Provided is an image processing apparatus. The image processing apparatus may determine whether a ray and a bounding volume including a primitive intersect each other, prior to determining whether the primitive and the ray intersect each other. An intersection test between the bounding volume and the ray may use a small amount of calculation compared to an intersection test between the primitive and the ray and thus, an amount of calculation used for rendering of the image processing apparatus may significantly decrease.

Abstract: A flexible tactile sensor apparatus is provided. The flexible tactile sensor apparatus may obtain information about an applied force, using a resistance between an upper nano wire array of an upper plate and a lower nano wire array of a lower plate, which may be changed based on a distance, between the upper nano wire array and the lower nano wire array, adjusted in proportion to the force.

Abstract: A delay locked loop in accordance with some embodiments of the inventive concept may include a delay signal generation part generating a first delay signal having a first phase and a second delay signal having a second phase by delaying a reference signal on the basis of a delay control signal; a phase synthesizing part generating at least one third signal having a third phase using the first delay signal and the second delay signal; and a phase detection part generating a control code by comparing the reference signal with each of the first delay signal, the second delay signal and the third signal.

Abstract: Provided are a composition for an oxide thin film, a preparation method of the composition, a method for forming an oxide thin film using the composition, an electronic device including the oxide thin film, and a semiconductor device including the oxide thin film. The composition for the oxide thin film includes a metal precursor and nitric acid-based stabilizer. The metal precursor includes at least one of a metal nitrate, a metal nitride, and hydrates thereof.

Abstract: Disclosed are apparatus and methods for encoding/decoding sampled color images acquired by using a CFA according to an exemplary embodiment of the present invention. An apparatus for encoding color images includes: an acquiring unit that acquires color images of a first color coordinate system; a conversion unit that converts the acquired color images of the first color coordinate system into color images of a second color coordinate system by treating a preset number of pixels as a unit; and an encoding unit that encodes the converted color images of the second color coordinate system to generate a compressed image. By this configuration, the present invention can convert color images into the YUV color coordinate system without interpolation of color images, reduce the data size increase caused by conversion into the YUV color coordinate system, and prevent reduced coding efficiency.
