An image acquisition system includes a cassette mounting unit that holds slide glasses in a plurality of stages, a cassette having an identification code imparted thereto being mounted in the cassette mounting unit, an identification code reading unit that reads an identification code from the cassette, an image acquisition unit that acquires image data of a sample held on the slide glass, and a control computer that associates the image data with cassette identification information included in the identification code read by the identification code reading unit, wherein the cassette mounting unit includes a notch portion that exposes a bar code imparted to the cassette, and the identification code reading unit includes an imaging unit that images the identification code exposed from the notch portion in a reading position.

Image acquisition system and image acquisition method

An image acquisition apparatusA includes a sample stagefor placing a sample S thereon, an image pickup devicecapable of acquiring a two-dimensional image and TDI driving, an image pickup optical systemincluding an objective lens, a scanning unit for acquiring an observation image while scanning the sample S by the image pickup deviceand the image pickup optical system, and a focus oscillation control devicefor controlling oscillation of a focus in the sample S so that an image pickup focus in the sample S oscillates at an oscillation frequency fs in an optical axis direction. The focus oscillation control devicesets the oscillation frequency fs so that the oscillation frequency fs substantially coincides with Ns times (Ns is an integer not less than 1) the basic frequency, which is a reciprocal 1/Ti of an image pickup period Ti of TDI driving in the image pickup device. Thus, an image acquisition apparatus capable of efficiently acquiring an observation image with focus extended can be realized.
