Information processing apparatus, stage-undulation correcting method, program therefor

摘要

Provided is an information processing apparatus including: a connection connecting to a microscope including a stage having a disposition surface on which a target object can be placed, and an image picking-up section including an objective lens for picking up an image of the object, the microscope being movable in first and second axis directions orthogonal to an optical axis of the objective lens and orthogonal to each other and in a third axis direction along the optical axis; a calculator calculating, as an undulation-correcting value, a value for correcting a misalignment of a position in the third axis direction for each predetermined image-capturing range smaller than the disposition surface; a correcting-value storage storing the calculated value; and a corrector correcting a relative distance between the stage and the objective lens on the basis of the stored value for each image-capturing range.

1. An information processing apparatus, comprising:
a connection to which a microscope as a target to be controlled is connected, the microscope including a moveable stage having a disposition surface on which a target object can be placed, and an image picking-up section including an objective lens, which is configured to pick up an image of the target object placed on the disposition surface, the microscope being movable in a first axis direction and a second axis direction, which are orthogonal to an optical axis of the objective lens and are orthogonal to each other and in a third axis direction extending along the optical axis; a calculator configured to calculate a plurality of undulation-correcting values, each undulation-correcting value being calculated for correcting a misalignment of a position of the moveable stage in the third axis direction for each respective predetermined image-capturing range of a plurality of predetermined image-capturing ranges, each of which has an area in the first axis direction and the second axis direction that is smaller than the disposition surface, in a region to be imaged on the disposition surface of the moveable stage, and the plurality of predetermined image-capturing ranges includes a plurality of rows of predetermined image-capturing ranges in the first direction and a plurality of columns of predetermined image-capturing ranges in the second direction, which is orthogonal to the first direction, wherein each of the plurality of predetermined image-capturing ranges is associated with respective coordinates in the first axis direction and the second axis direction and an undulation-correcting value for correcting misalignment of the position of the moveable stage in the third axis direction at the respective coordinates in the first axis direction and the second axis direction; a correcting-value storage configured to store the calculated undulation-correcting values for each of the predetermined image-capturing ranges, wherein each of the plurality of undulation-correcting values are stored for each respective predetermined image-capturing range; and a corrector configured to correct a relative distance in the third axis direction between the moveable stage and the objective lens for each predetermined image-capturing range on a basis of the plurality of stored undulation-correcting values for each respective predetermined image-capturing range.
