PROBLEM TO BE SOLVED: To provide an observation device and method, as well as observation control program that speeds up autofocus control for each observation, and can shorten a scanning time of an observation zone.SOLUTION: An observation device comprises: a stage 51; an image formation optical system 14 that an objective lens; a detection unit 18 that has displacement sensors 18a and 18b detecting a position in a vertical direction of a culture vessel 50; an image formation optical system control unit 21 that controls an image formation optical system drive unit 15 to move the objective lens in an optical axis direction on the basis of the position in the vertical direction of the culture vessel 50; and a horizontal direction drive unit 17 that causes the stage 51 to move in a main scan direction and in a sub-scan direction, and causes the stage to be reciprocated as to the main scan direction. The detection unit 18 is configured to detect the position in the vertical direction of the culture vessel 50 at a position on a movement direction forward side further than a position of an observation zone of the image formation optical system 14 with respect to the culture vessel 50, and switch the displacement sensor to be used in accordance with a change in movement direction of the main scan direction.SELECTED DRAWING: Figure 1 【課題】観察域毎のオートフォーカス制御を高速化し、観察域の走査時間を短縮可能な観察装置および方法並びに観察制御プログラムを提供する。【解決手段】ステージ５１と、対物レンズを有する結像光学系１４と、培養容器５０の鉛直方向の位置を検出する変位センサ１８ａ，１８ｂを有する検出部１８と、培養容器５０の鉛直方向の位置に基づいて、結像光学系駆動部１５を制御して対物レンズを光軸方向に移動させる結像光学系制御部２１と、ステージ５１を、主走査方向および副走査方向に移動させ、かつ主走査方向について往復移動させる水平方向駆動部１７とを備え、検出部１８が、培養容器５０に対する結像光学系１４の観察域の位置よりも観察域の移動方向前側の位置において培養容器５０の鉛直方向の位置を検出し、かつ主走査方向の移動方向の変更に応じて使用する変位センサを切り替える。【選択図】図１
