Abstract: PURPOSE:To heighten durability and the contrast of an input image without generating the accumulated error of a fast shutter with a video rate by controlling the angle of rotation of a motor by obtaining a pulse string of constant rate for the horizontal synchronizing signal of a composite video signal. CONSTITUTION:An image at the time of illuminating an object 3 by light sources 1 and 2 is fetched at every field period. A system controller 10 inputs a vertical synchronizing signal 9 from a synchronizing signal separation part 6 and a signal 23 from an origin sensor 22, and outputs a pulse input selection signal 13 and a travel command pulse signal 14 to a pulse distribution part 8.

Title: Optically molding method
Inventor: KURODA MASARU
IPC: B29C67/00
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To form a three-dimensional model in a short time by perpendicularly crossing photo-setting layers adjacent in optically scanning directions, and largely setting an interval of one optical scanning and next optical scanning from one end to the other of the one layer so that optically cured parts are not superposed once per plural times. SOLUTION: When optical scanning of one layer is finished, a direction of optical scanning of next layer is perpendicularly crossed with the scanning direction so far. It is scanned from one end to the other, thereafter optically scanned toward obliquely rearward, returned to a position of a side by h from a start P, and again similarly scanned. After a predetermined interval (h) is shifted until optical scannings (1) to (5), it is largely shifted by S in a lateral direction, and again a series of optical scannings (1) to (5) are executed. This skipping width S is larger than a cured layer width (b) of the photo-setting part. And, it is skipped by the S, and hence a non-photo-setting part is formed. The optical scanning for scanning at the interval (h) from the previous optical scanning is repeated plural times, and thereafter it is skipped by the S.

Title: Method and apparatus for detecting three-dimensional shape
Inventor: HARA YASUHIKO
IPC: G01B11/02
Filed: 1991-12-19
Abstract: PURPOSE:To detect a three-dimensional shape of an object having various light reflection characteristics stably in an optical manner regardless of lightness and darkness, a glossy surface and a plain surface. CONSTITUTION:Objects 1 and 1' are irradiated with a light spot by a polarization laser 10. Reflected light from the light spot is focused with an imaging lens to be detected with a photo detector 5 and height information is detected from information on the light spot. At this point, a quantity of the reflected light varies intense or weak according to conditions of reflection of the surface of the object. But the use of a logarithmic type characteristic detector 5, a quantity of light controller 16 for the control of a quantity of light and a polarizer 11 allow the detection of three-dimensional information of the objects 1 and 1' to adapt to the variation. It was difficult in the past to detect a three- dimensional shape of the object having various light reflection conditions. This allows the detection of the three-dimensional shape in a metal work part, electronic packaged substrate or other objects containing white or black thereby enabling the automation of inspection, measurement, positional recognition and the like.

IPC: G03F1/30
Filed: 1990-11-30
Abstract: PURPOSE:To obtain sufficient resolution and the depth of a focus in the case of a solid element pattern by using a phase shift mask and a multiple image- forming exposure method, and forming plural images of mask patterns at different positions in the optical axis direction. CONSTITUTION:The phase shift masks are used and the multiple image-forming exposure method is operated especially, under highly coherent illumination, and the distance between the same phase patterns opposite to each other across a light-shielding part is set to a prescribed distance or more in accordance with a space coherency and whether the multiple image-forming exposure method is applied or not.

The form of an effective light source in the face of a secondary light source of a reduction projection exposure device is set to a small one in the repeated directions of the repeated patterns and to a large one in the direction perpendicular to the above directions, thus permitting sufficient resolution and the sufficient depth of the focus to be obtained.

Title: Image encoding method and device
Inventor: OSAKO FUMINORI
IPC: H04N19/59
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To provide an image encoding method/device which can secure high picture quality of reproduced images with small computational complexity by performing the optimum thinning according to the local characteristic of an image. SOLUTION: An input image 302 is divided into small blocks 304 which undergo the vector detection by a small block division part 303 and sent to a subtracter 309. A reference image 306 which is preceding by one frame and received from a frame memory 305 is spatially shifted by a shift part 308 by an extent equal to the candidate vector sent from a candidate vector setting part 307. Then the subtracter 309 calculates the difference between the image 306 and every block 304, and the image 306 is sent to a pixel thinning part 310. The part 310 sets an inter-pixel thinning pattern based on the motion vector direction 318 that is already set and thins the pixels. Thus the correct motion vector is detected despite the reduction of the computational complexity that is needed for the motion vector detection processing.  Then the reproduced images of high picture quality can be obtained with small computational complexity.
