Abstract:
A method and system for correcting a non-linear characteristic of an image, wherein an input image is digitized to produce digital image data representative of the image and a histogram of the digital image data is produced. At least a first pixel value characteristic of a variable under which the image was derived is extracted from the histogram. A plurality of non-linear correction curves relating original pixel values to corrected pixel values for different degrees of the variable are stored in a memory, and a particular one of the correction curves is selected based at least in part on the first extracted pixel value and a predetermined corrected pixel value. Corrected image data are then formed utilizing the selected correction curve by correcting each original pixel value of the image to a respective corrected pixel value based on the relationship therebetween defined by the selected correction curve, and a non-linearity corrected image is produced based on the corrected image data.
Abstract:
A housing has an intake passage extending substantially in a vertical direction of a vehicle. A valve is configured to open and close the intake passage. A shaft supports the valve. A bearing supports the shaft. A hose is connected with an upper side of the housing in the vertical direction and configured to lead intake air into the intake passage. A communication passage configured to communicate an inside of an internal combustion engine of the vehicle with the hose. The communication passage has an opening in the vicinity of a point directly above the bearing. The hose has a wall surface defining a condensate passage, which connects the opening with a target location from which condensate is to be dropped.
Abstract:
A polyester composition produced without using an antimony compound as a polycondensation catalyst and including (I) a composition containing, on a weight basis, 30 ppm or less of antimony, 0.5 to 50 ppm of titanium, and 0.1 to 100 ppm of phosphorus, in which the number density of titanium-containing particles, the equivalent circular diameter of which is 1 μm or more, is less than 100/0.02 mg; and (II) a composition containing, on a weight basis, antimony, titanium and phosphorous as defined above, in which organic polymer particles are contained in amount of 0.1 to 5 wt %, the organic polymer particles having an average particle diameter determined by dynamic light scattering of 0.05 to 3 μm and containing 0.01% or less of coarse particles relative to the total number of the particles, the coarse particles having a diameter at least twice the average particle diameter.
Abstract:
The present invention aims to provide a practical polyester that can be produced substantially without using an antimony compound as a polycondensation catalyst. (I) The present invention provides a polyester resin composition containing, on a weight basis, 30 ppm or less of antimony, 0.5 to 50 ppm of titanium, and 0.1 to 100 ppm of phosphorus, in which the number density of titanium-containing particles, the equivalent circular diameter of which is 1 μm or more, is less than 100/0.02 mg; and (II) The present invention provides a polyester resin composition containing, on a weight basis, 30 ppm or less of antimony, 0.5 to 50 ppm of titanium, and 0.1 to 100 ppm of phosphorus, in which organic polymer particles are contained in amount of 0.1 to 5 wt %, the organic polymer particles having an average particle diameter determined by dynamic light scattering of 0.05 to 3 μm and containing 0.01% or less of coarse particles relative to the total number of the particles, the coarse particles having a diameter at least twice the average particle diameter.
Abstract:
An image displaying apparatus includes a memory, an image reader, an image processor, an image adder and a display. The memory stores a plurality of medical images including temporally sequential images of a common portion of a same patient taken at different points of time. The image reader reads out the plurality of medical images from the memory. The image processor processes at least two of the plurality of medical images read out from the memory according to registration information of the at least two of the plurality of medical images so as to obtain a processed image. The image adder adds one of the plurality of medical images read out from the memory to the processed image so as to obtain an addition image. And the display displays the addition image.
