Title: Solid-state color image pickup device
Inventor: ASADA RYOJI
IPC: H04N9/69
Filed: 1990-05-11
Abstract: PURPOSE:To improve the resolution by converting R, G, B signals into original linear R, G, B signals with an inverse gamma correction circuit, adding the R, G, B signals at a prescribed rate by a Y matrix circuit, forming a broad band luminance signal land applying gamma correction. CONSTITUTION:A Y matrix circuit 15 restores each of R, G, B signals subjected to nonlinear conversion by gamma correction circuits 1, 2, 3 to an original linear signal by means of inverse gamma correction circuits 27, 28, 29. Then the R, G, B signals are added to obtain a luminance signal. Thus, a high frequency signal is replaced into a high frequency component of a broad band signal not including a loopback component to eliminate the loopback component of each color signal and moire and color blurring are reduced in the R, G, B outputs.

Title: Formation of thin film
Inventor: YAMADA YOSHIAKI
IPC: H01L21/31
Filed: 1986-05-30
Abstract: PURPOSE:To improve coverage in small apertures or gaps and to form a highly reliable film without a risk of disconnection, by applying ion beams of an inert gas obliquely to a substrate simultaneously with forming the film on the substrate by means of the sputtering process. CONSTITUTION:A high-frequency voltage is applied to a cathode electrode 2 to cause glow discharge in a vacuum chamber 1, so that a target 4 is sputtered with argon ions and particles from the target are deposited on a substrate 6 to grow a thin film. Simultaneously with the sputtering, argon ions from an ion source 7 are also applied to the substrate 6 at a desired density of energy or current. The ion beams are applied obliquely to the substrate 6 while the substrate 8 is rotated by a holder 5. Since these ion beams do not reach the bottoms of apertures or of small gaps, such regions are etched much less than the other regions. As a result, said film can be grown without overhangs in the apertures or small gaps.
