Title: Interpolation field generating circuit and field double speed conversion circuit
Inventor: NAMIOKA TOSHIYUKI
IPC: H04N7/01
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To obtain an interpolation field generating circuit and a field double speed conversion circuit that can prevent deterioration in image quality due to detection of an erroneous motion vector when no image correlation is in existence between two fields in the case of generating an interpolation field from two adjacent fields. SOLUTION: A block correlation arithmetic circuit 104 detects a block correlation difference between two adjacent fields, and in the case that the detected difference exceeds a prescribed difference range by which presence of correlation can be discriminated, since that can be decided to be a case there is no correlation between two field images (scene change or the like), a selector 116 in a motion vector detection circuit forcibly set a motion vector to a zero vector in order to avoid detection of an erroneous motion vector and gives the result to an interpolation circuit 118 for generating an interpolation field. That is, an unstable motion vector due to erroneous detection cannot be supplied to the interpolation circuit 118.

Title: Strobe signal generation synchronous semiconductor device
Inventor: CHO YONG DEOK
IPC: G11C7/22
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To enable a device to perform a high-speed operation by distributing a frequency-divided clock while generating it from an original clock and generating strobe signals which have the same frequency as that of the original clock and whose pulse widths are properly adjusted to reduce current consumption. SOLUTION: A clock signal gclk is generated by dividing a CPU clock to one half to be distributed to respective circuit parts of a chip, that is, the leading part, the end part and left and right side parts of the chip. Then, strobe signals ck-pul-top, ck-pul-bot, ck-pul whose frequencies are equal to that of the CPU clock and which have proper pulse widths with respect to the respective circuit parts are generated by three frequency multipliers having the same constitution from the clock distributed to the respective circuit parts. The pulse widths are adjusted by delay elements 205. Thus, the pulse didth can be made narrower at a high-speed operation and a margin can be reduced.

Filed: 1990-05-30
Abstract: PURPOSE:To prevent the latch up circuit from being made while integrating the circuit by a method wherein the first region is provided with the larger band gap or higher recoupling level than those of the second region. CONSTITUTION:A P type porus silicon layer 100 is formed on the main surface of a P type substrate 41; an N-type polycrystal silicon layer 102 is formed on the main surface of the P type porus silicon layer 100 through the intermediary of a P type polycrystal silicon layer 101; one end of the P-type polycrystal silicon layer 102 is connected to an input terminal while the other end is connected to the gate of CMOS. Through these procedures, since the numbers of electrons implanted in the P-type substrate 41 to reach an N well 111 can be reduced, the latch up circuit can be prevented from being made without widening the chip space. Furthermore, the insulation breakdown will not occur since there is no insulating film between the N-type silicon layer 102 and the P-type substrate 41. Accordingly, an input protective circuit can be made without deteriorating the surge yield strength of the N-type polycrystal silicon layer 102 as an input resistor.

Title: Photodetector
Inventor: FUJII EIJI
IPC: H04N5/335
Filed: 1986-06-17
Abstract: PURPOSE:To reduce a smear remarkably by forming one part of a barrier layer by an insulating film. CONSTITUTION:A barrier layer 15 is shaped through the same method as a conventional method, and the ions of O<+>2 are implanted at large acceleration voltage of approximately 170KeV before forming a charge transfer section 14. One part of a barrier layer 15 is converted into an silicon oxide film 12 through annealing for several hr. Charges generated under the silicon oxide film 12 do not leak to the charge transfer section 14 by the high barrier of the silicon oxide film 12. Since the width of a section under the charge transfer section of the barrier layer 15 can be decreased, the quantity of electron-hole pairs generated by leaking light can be reduced while charges generated can also be captured by considerable probability at an interface level between the barrier layer 15 and the silicon oxide film 12. Accordingly, a smear is minimized remarkably.

Abstract: PURPOSE:To display an area where accurate phase detection is not performed in an easy-to-understand state by providing a level decision device which decides an output level from an intensity detector and a display device which displays a distance image in consideration of the signal from the level decision device. CONSTITUTION:The output light of a laser 1 is intensity-modulated by an optical modulator 2 which is driven by a transmitter 3 and projected on an object 6 through a holed mirror 4 and a scanner 5.
