Patent ID: 11397313

Abstract:
An observation apparatus, an observation method, and an observation program capable of capturing an image by appropriately adjusting a focus regardless of a size of an effective range in which a distance to a cultivation container can be measured within a field of view are provided. An observation apparatus includes an imaging unit 37 that images an observation target in a field of view smaller than an accommodation part 22 at a series of imaging positions and acquires a series of partial images, a measurement unit 38 that measures a distance from the imaging unit 37 to the accommodation part 22, a storage unit 44 that stores shape information of a container 20 and a series of imaging position information, a calculation unit 45 that calculates effective range information indicating an effective range in which the measurement unit 38 is capable of performing measurement before imaging within a field of view of the imaging unit 37 at the imaging positions, based on the shape information and the imaging position information, and a control unit 40 that controls a focus of the imaging unit 37 using a measurement result measured by the measurement unit 38 in the effective range and a measurement result of the measurement unit 38 in a field of view adjacent to the field of view including the effective range in a case where the effective range is smaller than or equal to a threshold value.
