摘要 |
A method includes: obtaining a plurality of object images, the plurality of object images being taken by an image pickup device while moving a focal position within a predetermined range, the image pickup device being capable of taking images of an object at arbitrary focal positions within the predetermined range; calculating a first in-focus position within the predetermined range based on pieces of contrast information on a manually-taken object image group, the manually-taken object image group including the plurality of object images taken while manually moving the focal position within the predetermined range; and calculating a second in-focus position within the search range based on pieces of contrast information on an automatically-taken object image group, the automatically-taken object image group including the plurality of object images taken while automatically moving the focal position within a search range, the search range being determined with reference to the calculated first in-focus position. |

1. An information processing apparatus, comprising:
an obtaining unit configured to obtain a plurality of object images, the plurality of object images being taken by an image pickup device while moving a focal position within a predetermined range, the image pickup device being capable of taking images of an object at arbitrary focal positions within the predetermined range; a first calculator capable of calculating a first in-focus position within the predetermined range based on pieces of contrast information on a manually-taken object image group, the manually-taken object image group including the plurality of object images taken while manually moving the focal position within the predetermined range; and a second calculator capable of calculating a second in-focus position within the search range based on pieces of contrast information on an automatically-taken object image group, the automatically-taken object image group including the plurality of object images taken while automatically moving the focal position within a search range, the search range being determined with reference to the calculated first in-focus position. |
