摘要： Disclosed is an optical imaging method and device enabling display and 3D measurement of tridimensional objects (1), whereby at least two individual images are captured one after the other and the effective amount of radiation energy for the image conversion is controlled or regulated differently for these individual images. By employing adustable optical means (10-14) for the illumination of the object or in the optical path for the imaging of the object on the image converter (15) it is possible to acquire a larger amount of visual information on the object observed than that which is available in an individual image due to the limitations imposed by the design of the converter used (15). The invention relates to processes and design forms of the device enabling recording units to be designed, using simply and generally commercial components, which are able to display and measure larger objects (1) despite a reduced field of vision imposed by the design. This is especially useful for diagnosis in invasive applications in the bodies of humans or animals.

摘要： Provided is an image reading apparatus for suppressing an image defect ascribable to shading correction using a white reference plate arranged at a position different from a reading position of an original. The image reading apparatus includes a reading means configured to read an image from the original passing through the reading position, the white reference plate arranged such that a distance between the reading means and the white reference plate is larger than the distance between the reading means and the reading position, and a control system. The control system includes a memory for backup configured to store in advance correlation data representing a correlation between a reading result of the white reference plate obtained by the reading means, and a reading result of a reference member having a uniform density and arranged at the reading position.

摘要： The present invention relates to a novel objective method for assessing high contrast resolution of images based on Rayleigh criterion and a testing operating method. The novel objective method for assessing high contrast resolution of images based on Rayleigh criterion involves combining the Rayleigh criterion with regional pixel intensity profiles for simultaneous application to high contrast resolution images of CT equipment, which allows objective assessment by using the Rayleigh criterion after the drawing of the regional pixel intensity profiles; the introduction of a normalized margin and the use of a Lanczos window function for interpolation processing on original images enable a considerably practical, time-effective and operable objective assessment method that is convenient for testers to use and also easy for CT equipment operators to use. Such a method, just like a modulation transfer function (MTF) method, is capable of tracking subtle and slow changes of the high contrast resolution of CT equipment in the life cycle thereof objectively and accurately, thus allowing improvement of the use efficiency of the CT equipment in the life cycle thereof; therefore, the method is suitable for extensive popularization and application.
