Title:
DEVICE, METHOD, AND PROGRAM FOR CAPTURING MICROSCOPIC IMAGES
Document Type and Number:
Japanese Patent JP2015084062
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a device, method, and program for capturing microscopic images, which allow for capturing images using light having a pattern without deteriorating image quality.SOLUTION: Patterned measurement light is produced by a projection light modulation element 112 and is irradiated on an object S under measurement. A spatial phase of a produced pattern is sequentially shifted on the object S under measurement by predetermined increments by the light modulation element 112. A light receiving unit 120 receives light from the object S under measurement and outputs a light reception signal that represents received light intensity. A plurality of sets of image data generated at a plurality of phases of the pattern using the light reception signal from the light receiving unit 120 is used to generate sectioning image data representing an image of the object S under measurement. Based on periodicity of non-light-guiding sections between multiple modulation-pixels of the light modulation element 112, portions of the image data or sectioning image data corresponding to the non-light-guiding sections are removed by a filtering process.
