Image reproducing device and observation system for selecting images using tag information attached in accordance with information that operation is performed on sample and input when at least one of images is acquired

1. An observation system comprising:

an imaging unit configured to acquire a plurality of images relating to a biological sample along time series;

an input interface to which an operation by a user is input; and

one or more processors configured to:

acquire image group data including the plurality of images acquired by the imaging unit, and tag information per operation on the biological sample,

wherein the tag information is attached in accordance with information that an operation is performed on the biological sample, and input by the user through the input interface when at least one of the images is acquired;

select, from the plurality of images using the tag information, images to be reproduced along the time series as reproduction selected images; and

output to a display, data relating to the images for the reproduction selected images to be reproduced along time series.

2. The observation system according to claim 1 ,

wherein the operation on the biological sample is at least one of a subculture operation on the biological sample, a medium changing operation, and an operation of adding a reagent to a medium.

3. The observation system according to claim 1 , wherein the one or more processors are configured to:

further acquire a selection operation by the user to select one of the images, as a user selected image; and

select images including the user selected image, as the reproduction selected images.

4. The observation system according to claim 3 ,

wherein the one or more processors are configured to perform one of:

select, as the reproduction selected images, images ranging from an image that is associated with the tag information and is obtained immediately before the user selected image, to an image that is associated with the tag information and is obtained immediately after the user selected image or a last image of the plurality of images; and

select, as the reproduction selected images, images ranging from an image that is associated with the tag information and is obtained immediately before the user selected image or a first image of the plurality of images, to an image that is associated with the tag information and is obtained immediately after the user selected image.

5. The observation system according to claim 3 ,

wherein the one or more processors are configured to output a relation between the image and the tag information and information on the plurality of images to the display in order for the user to select the user selected image.

6. The observation system according to claim 3 ,

wherein the one or more processors are configured to select the user selected image as a first image or a last image of the reproduction selected images, in accordance with an operation by the user.

7. The observation system according to claim 1 ,

wherein the tag information is attached to the image acquired immediately before or immediately after the input interface is operated by the user.

8. The observation system according to claim 1 ,

wherein the tag information is information that is recorded separately from the image and indicative of a time relationship between the image obtained before the input interface is operated by the user and the image obtained after the input interface is operated by the user.

9. An image reproducing device comprising:

one or more processors configured to:

acquire image group data including a plurality of images relating to a biological sample along time series, and tag information on at least one tag that relates to an operation on the biological sample and is associated with at least part of the images;

acquire a unit number through input by a user, the unit number indicating a number of units on a condition that one unit is set to an interval between the tag information and the next tag information along the time series;

select, from the plurality of images, using the tag information and in units corresponding to the input unit number, images to be reproduced along the time series as reproduction selected images; and

output to a display, data relating to the images for the reproduction selected images to be reproduced along time series.

10. A method comprising:

one or more processors configured to:

acquiring image group data including a plurality of images relating to a biological sample, acquired by an imaging unit along time series, and tag information per operation on the biological sample,

wherein the tag information is attached in accordance with information that an operation is performed on the biological sample, and input by a user through an input interface when at least one of the images is acquired;

selecting from the plurality of images using the tag information, images to be reproduced along the time series as reproduction selected images; and

outputting to a display, data relating to the images for the reproduction selected images to be reproduced along time series.
