IPC: H04N1/409
Filed: 1993-12-15
Abstract: PURPOSE:To improve picture quality through a simple operation by shaping and working the contour of a picture like a character or a graphic, etc. CONSTITUTION:When a picture contour shaping mode is designated through an operating part 310, and besides, the object area to be processed of an original is designated by an area designating device 380, an original picture is read by an image scanner 100, and is stored in a memory unit 330. The character picture of the object area to be processed is extracted by a data extracting part 340, and the contour of the character picture is extracted by a contour extracting part 3501, and whether it is a straignt line or a curved line is judged by a straight line.curved line approximating part 3502 from the angle and the length of a continuous contour line, and by approximating contour data, it is shaped and worked so that the straight line becomes sharp and the curved line becomes smooth. A picture formation processing part 360 writes the approximated contour data in the memory unit 330, and simultaneously, it forms an output picture on the memory unit 330 by painting out the inside of the contour data.

Title: Image data compressing device
Inventor: NAGATOMO YASUHITO
IPC: H04N1/41
Filed: 1990-11-20
Abstract: PURPOSE:To reproduce easily visible images having decreased quantization noises and block distortions by generating the threshold corresponding to each one of the conversion coefft. converted by an AD/DC conversion means, comparing this threshold and the absolute value of the respective conversion coeffts and making the coeffts. below this value to zero. CONSTITUTION:The conversion coeffts. outputted from the AD/DC conversion means 102 are inputted sequentially from the coeffts. of lower-frequency components to a threshold discriminating means 104. A threshold generating means 103 generates the threshold in correspondence to each one of the conversion coeffts. and outputs this threshold to a threshold discriminating means 104. The absolute value of the inputted conversion coeffts. is calculated in the threshold discriminating means 104 and is compared with the threshold inputted from the threshold generating means 103. The conversion coefft. is outputted as it is if the absolute value of the conversion coefft. is above the threshold. Zero is outputted if the value is below the threshold. Namely, the quantity of the codes to be generated is decreased without increasing the quantization step by preferentially making the coefft. of the low level zero. The easily visible images having the decreased quantization noises and block distortions are reproduced in this way.

Abstract: PROBLEM TO BE SOLVED: To make a carrier leak characteristic compatible with an intermodulation distortion characteristic. SOLUTION: When a deciding means 31 decides that a level value A designated by an output level setting means 29 is lower than a prescribed value or a prescribed range, a level diagram switching means 32 reduces the attenuation quantity of variable attenuators 22 and 23 so that the level difference between a digital modulation signal outputted from an output terminal 20a and a residual carrier can be equal to or more than a prescribed value and also sets the attenuation quantity of a variable attenuator 28 that the digital modulation signal of the value A can be outputted from the terminal 20a.  When the means 31 decides that the designated level value A is higher than the prescribed value or the prescribed range, the means 32 increases the attenuation quantity of the attenuators 22 and 23 so that the level difference between the digital modulation signal outputted from the terminal 20a and intermodulation distortion can be equal to or more than a prescribed value and also sets the attenuation quantity of the attenuator 28 so that the digital modulation signal of the value A can be outputted from the terminal 20a.

Abstract: PURPOSE:To prevent the deformation of a dummy gate from occurring without affecting the element characteristics by a method wherein n<+> ions are implanted before the cleaning process after forming a dummy gate during gate substitution process. CONSTITUTION:A dummy gate 5 is formed by undercutting a lower resist 5A by RIE(Reactive Ion Etching) process using O2 so as to make the line width thereof finer than that of an SiO2 film 5B. At this time, Si ions are implanted through a SiN film 4 to form n<+> layers 6 so that a resist may be hardened to enhance bond properties onto the SiN film 4. Later, after cleaning up the dummy gate 5 usings semicoclean and NH4F, SiO2 films 7 in inverse patterns 2 are formed by lifting of the dummy gate 5. Next, windows are made in SiO2 films 7 and the SiN film 4 to form ohmic electrodes 8, 9 in source drain regions. Through these procedures, the resist can be hardened by ion implantation in n<+> layers 6 to enhance the bond properties so that the deformation in the dummy gate 5 during the later cleaning process may be prevented from occurring.
