Filed: 1989-12-21
Abstract: PURPOSE:To minimize the difference between atmosphere which is actually seen by eyes and atmosphere on a printed photograph without executing troublesome operation by detecting a season when photographing is executed and adding correction to the arithmetic operation of an exposure value corresponding to the brightness of an object based on the detected result. CONSTITUTION:Based on the season detected by a season detection means 102, and exposure value correction means 103 adds the correction to the arithmetic operation of the exposure value by an exposure value arithmetic operation means 101, that means, the arithmetic operation of the exposure value based on the brightness of the object. Therefore, when the photographing with counter light on a seaside where the sunlight is strong or the photographing whose background is snow is executed, for example, the under-exposure is prevented without correcting the exposure by band. Thus, the difference between the atmosphere which is actually seen by the eyes and the atmosphere on the photograph is minimized without executing the complicated operation.

Title: Compensating method for thickness of organ
Inventor: LIENARD JEAN
IPC: G06T5/40
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To compensate for in particular the variations in the thickness at the margin between the high and low density areas of a radiographically obtained organ by deriving an algebraically compensated image to reset a pixel of a low or high level to a threshold and totaling a part of a thickness image and a part of the compensated image to obtain an image with compensated thickness. SOLUTION: This method is executed by an X-ray device which includes an X-ray source and a detection means which detects an X-ray beam 4 after an X-ray 5 passed through an organ. The detection means can transform the beam 4 into a digital electronic signal. Then an image of the radiological thickness is calculated from a digitized image for the organ that is scanned by the beam 4. The thickness of zero corresponds to an area where no organ exists and the thickness threshold is defined. An algebraically compensated image is derived from the thickness threshold, and a pixel of a low or high level can be reset at the threshold equivalent to its threshold value. Furthermore, the ratios between the thickness and compensated images are totaled and a compensated thickness image is obtained.

Abstract: PURPOSE:To prevent the damage of a switch part to be caused by a shock from the outside and facilitate the maintenance by forming a push button part and the switch part separately. CONSTITUTION:When a cap 5 is pushed, an inverted dish-shape part 3a of a silicone rubber 3 is bent by the pushing force, and a projection 7a of a lever 7 is pushed to the lower, and the lever 7 is turned around of a shaft 8, and the tip 7c of the lever 7 is moved to the lower, and finally, the tip 7c reaches a position showed with a broken line, and a magnet 9 reaches close to a lead switch of a switch part 12 to turn ON the switch part 12. Since the push button part 11 and the switch part 12 are separated under the usual condition, even if the cap 5 is pushed or hit strongly, the lever 7 never transmit a large force to the switch part directly. The force large enough to break the switch part is thereby not given.
