Abstract: A method of patterning an underlying structure includes the following. A first patterning process is performed on the underlying structure to form a first patterned underlying structure including a first opening. A patterned photoresist layer is formed, and the patterned photoresist layer fills the first opening. A second patterning process is performed on the first patterned underlying structure to form a second patterned underlying structure including the first opening and a second opening.

Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A selective motion vector prediction method and a motion estimation method and a device thereof applicable to a scalable video coding (SVC) system are disclosed. The selective motion vector prediction method includes the steps of performing an inter prediction to obtain a first motion vector prediction center; performing an inter-layer motion prediction to obtain a second motion vector prediction center; in the case the first and the second motion vector prediction center satisfying a preset condition, using the same reference data to calculate the rate-distortion costs for the inter prediction and the inter-layer motion prediction; and using the rate-distortion costs as a basis to select one of the inter prediction and the inter-layer motion prediction for applying to the SVC system. Thus, the same reference data is shared to enable reduced memory access in the process of coding and accordingly, reduced cost of and power consumption by memory access.
