Abstract: Provided are an analysis device, an analysis method, a program, and a calibration method. The analysis device includes: an obtaining part obtaining an image captured by an image capturing part that captures an image of one or more first markers provided on an estimation target; and a calibration part calibrating a conversion rule from a sensor coordinate system to a segment coordinate system based on the image. A posture of the first marker relative to at least one inertial measurement sensor does not change, and the posture with respect to the image capturing part is recognizable by analyzing the captured image. The calibration part derives the posture of the first marker with respect to the image capturing part, derives a conversion matrix from the sensor coordinate system to a camera coordinate system based on the derived posture, and calibrates the conversion rule by using the derived conversion matrix.

Abstract: An image signal representing image information containing a periodic pattern is processed before it is broken up into halftone dots. First, the image information is averaged to generate an unsharpness signal, and then the unsharpness signal is processed for edge sharpness to generate a sharpness signal. Thereafter, a halftone-dot image is generated from the sharpness signal. More specifically, the sharpness signal Sij* is generated from a first unsharpness signal Uij which is produced by averaging the image information and a second unsharpness signal Uij which is produced by averaging the first unsharpness signal Uij, according to the equation:Sij*=Uij+K.multidot.(Uij-Uij)wherei=1, 2, . . . n,j=1,2, . . . n, andK: sharpness parameter.The halftone-dot image thus reproduced is sharp and free of a moire pattern which would otherwise result from the periodic pattern.
