Abstract: Provided is a cognitive experiment method for change in periphery region image quality for parameter determination of a foveated hologram. According to an embodiment, a cognitive experiment method for determining foveated image parameters includes: generating a foveated image which includes a foveal region and a periphery region while reducing image quality regarding the periphery region; displaying the generated foveated image; receiving an input of a response to image quality of the periphery region from a subject; and collecting information regarding appropriate image quality of the periphery region, based on the response inputted by the subject. Accordingly, in applying a foveated hologram generation algorithm for real-time reproduction, various parameters such as a boundary between a foveal region image and a periphery region image in a foveated hologram, and a degree of quality degradation of the periphery region image may be appropriately determined through a cognitive experiment.

Abstract: A 2-input NOR gate with NMOS transistors and PMOS transistors formed on different semiconductor layers, and a fabricating method for the same, are disclosed. The NMOS and PMOS transistors of the CMOS transistors are formed on different semiconductor layers unlike in the conventional technique, thereby improving the chip density. Further, the device isolating film forming process can be eliminated, and therefore, the fabrication process can be simplified, while the problems such as punch-through, latch-up and the like can be solved.
