IPC: H03M13/00
Filed: 1995-05-25
Abstract: PURPOSE: To estimate a picture element value of a missing picture element more accurately by extracting normal picture elements used for interpolation from every direction of missing picture elements uniformly so as to use a changing inclination of picture element values in both longitudinal and lateral directions for the interpolation. CONSTITUTION: Coordinates of missing data detected by an error correction decoder 6 are received to check an area of missing data. A picture element in a missing area and a normal reception picture element for interpolation are selected to be a picture element value (g) of the missing picture element and n-sets of normal reception picture elements to surround the picture element (g) are all used. Two normal picture elements are extracted. A point in a 3-dimension space whose coordinate is based on a coordinate of each picture element and its picture element value corresponds to each picture element, and an area of a triangle of three points is obtained as a function of (g). The area is calculated with respect to all values by which the (g) takes and the value (g) minimizing the area is used for a picture element value by the interpolation of the missing picture element (g).  The interpolation value of all missing picture elements is calculated by repeating the processing as above.

Abstract: PURPOSE:To reduce parasitic resistance and increase heat radiation by forming a channel region into SIO structure and a source and a drain region into bulk structure. CONSTITUTION:An Si thin film 16 is formed as a semiconductor film in a channel region on a thermal oxidation film 14. Further, a gate oxide film 18 is formed on the Si thin film 16 to form a gate electrode 20 thereon. And then on the Si thin film 16 formed are an N-type source and an N-type drain region 22, 22b into bulk structure so as to overlap a part of a field oxide layer 12. Thereby, an Si thin film is formed in a channel region to make SOI structure. On the other hand, the source and the drain region make bulk structure to be thicker as compared to the channel region. Therefore, a parasitic resistance produced in the source and drain regions can be reduced. Further, with bulk structure, the source and drain regions are formed directly on a semiconductor substrate, so that heat generated in those regions may be efficiently radiated to the semiconductor substrate.
