Title: Camera parameter estimating method using order statistic and program recording medium
Inventor: TANIGUCHI YUKINOBU
IPC: H04N5/262
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To make a camera hardly be affected by noises by calculating an error amount between images as what is the smallest among values that are in upper α% when differences in pixel values are arranged in order of magnitude and making a conversion parameter that minimizes the calculated error amount a camera parameter. SOLUTION: An image inputting part 11 receives a series of image data 15 photographed by a camera and a calculating part 12 calculates differences in each pixel value when two continuous images of the data 15 are shifted in the range of a prescribed search window. A histogram producing part 13 produces a histogram about the absolute value of the calculated difference. And, an error amount calculating part 14 makes what is the smallest among values that are in upper α% (0<α<100) an error amount and makes a conversion parameter that minimizes the error amount within a search range a camera parameter. Thus, it is possible to estimate the camera parameter without being affected by noises.

Abstract: PROBLEM TO BE SOLVED: To provide a surface plasmon resonance sensor apparatus in which a temperature can be compensated precisely. SOLUTION: In a sensor chip at a surface plasmon resonance sensor apparatus, the surface of a high-refractive-index light transmission medium 1 such as a glass or an acrylic resin is provided with a gold or silver metal thin film 2 which is used to generate surfac eplasmon resonance. The metal thin film 2 is divided into a detection part 2a and a reference part 2b in terms of its use. The detection part 2a is exposed so as to come into contact with a sample, and the reference part 2b is covered with a material whose refractive index is constant, e.g. with a coating layer 4 by a fluororesin. The thickness of the coating layer 4 is set at 50nm or higher preferably at about 100nm or higher, so that evanescent waves which are leaked from the surface of the metal thin film 2 are confined inside the layer.  When a plasmon resonance angle measurde by using the reference part 2b is utilized as a reference value, the temperature of the plasmon resonance angle regarding the sample measured by using the detection part 2a is compensated.
