Title: Method for loading frame of data into space light modulator for pulse width modulation display
Inventor: DONARUDO BII DOHAATEI
IPC: G09G3/18
Filed: 1995-06-13
Abstract: PURPOSE: To improve the picture quality of a PWM picture display system at a high optical efficiency without requiring any increased band width by using a spatial optical modulator constituted for designating divided resetting addresses. CONSTITUTION: A display frame period is divided into time slices and each frame is formatted to a bit surface. Each bit surface has one bit of data at every picture element and expresses a bit weight (bit surfaces having higher bit weights are displayed over many time slices) and formatted into a reset group related to a spatial optical modulator. The displaying time to higher-rank bits 7-5 is segmented so that data may not be displayed continuously, but in segments. During loading, the segments corresponding to bit surfaces are temporarily aligned to the next preferential group from one reset group. The display time to the reset group of lower-order bits 0-4 is not segmented, but temporarily aligned in a possible degree without causing any loading collision.

IPC: G06T7/00
Filed: 1993-07-22
Abstract: PURPOSE:To precisely know an inferiority occurring condition by calculating a determining area, and by checking whether the determining area is large or small so as to determine a degree of missing. CONSTITUTION:An image processing circuit receives an image output from a CCD camera, and obtains a binary image V. Further, boundary coordinates (a, b) in the X-axial direction and boundary coordinates (c, d) in the Y-axial direction in the image V is obtained. Further, a straight line LX passing the coordinates (a, b) is obtained from the coordinates (a, b) while a straight line LY passing the coordinates (c, d) is obtained from the coordinates (c, d), and the virtual crosspoint A between the two straight lines LX, LY is obtained from these lines. Thereafter, a plurality of points on an edge along, for example, the Y-axial direction are plotted in the vicinity of the coordinates A in the image V, and then, boundary coordinates a1, b1 are again obtained. Then a straight line segment D connecting between the coordinates a1, b1 is obtained. Further, a determining distance L between the line segment D and the coordinates A is calculated. Further, a determining area KA=LXDdivided by 2. Further, whether the area KA is large or small is checked so as to determine the degree of missing. The result of the determination is fed-back to a control line, and thereby it is possible to precisely know an inferiority occurring condition.

Abstract: PURPOSE:To suppress the heating of a light source lamp, to prevent the increase in temperature of a constant temperature part and to make it possible to improve measuring accuracy, by putting out the light source, which emits measuring light, during a period when optical density of reflected light is not measured. CONSTITUTION:A chemical analysis slide 1 has a chemical analysis film 1b, where a material to be measured is dropped on a reagent layer. The slide 1 is kept under a constant temperature state for a specified time on a slide holding member 10 by conducting a current to a constant temperature part 20. Then, the reagent of the film 1b acts on the material to be measured and color reaction is yielded. Thereafter, measuring light emitted from a light source lamp 28 is reflected by the lower surface of the film 1b in a light measuring part 21. The reflected light is received in a photodetector 29. Before the measurement of the amount of the reflected light, the lamp 28 is temporarily lighted. The lamp 28 is lighted again after a specified OFF time. Thus the optical density of the reflected light from the slide 1 is measured. Therefore, the heating of the lamp 28 is suppressed, and the increase in temperature of the constant temperature part 20 and a constant temperature cover part 20a is prevented. Thus the stable amount of the light is obtained, and the measurement of the accurate optical density of the reflected light can be carried out.
