An image sensor includes first pixels and a first source follower transistor, which are disposed adjacent to each other in a first pixel area in a column direction, and second pixels and a second source follower transistor, which are formed in a second pixel area adjacent to the first pixel area in a row direction by the same number of the first pixels, wherein when the first pixels share the first source follower transistor and the second pixels share the second source follower transistor, while pixels selected from the same row are activated, the first source follower transistor and the second source follower transistor being activated are disposed so that locations thereof have a diagonal symmetry.

Image sensors having reduced interference between pixels

The wheel-type high-speed railway system includes rails provided on a railroad track and configured such that wheels provided in a bogie of a vehicle come into contact with them, a support provided on a tread surface of a railroad track between the rails, a repulsive Linear Synchronous Motor (LSM) provided between the bogie and the support and configured to improve traveling performance by reducing axle load in a high-speed region, first and second steel plates mounted on both sides of the support in inclined positions, and first and second attractive Dynamic Motion Control (DMC) magnets mounted on the bogie of the vehicle in inclined positions to correspond to the first and second steel plates, and configured to generate attractive force.
