CULTURE MANAGEMENT APPARATUS, ESTIMATION METHOD, AND COMPUTER-READABLE MEDIUM

1 . A culture management apparatus comprising:

a control device that estimates a state of a specific medium component constituting a culture medium based on images

wherein the images include both the culture medium and a cell in the culture medium acquired at different times.

2 . The culture management apparatus according to claim 1 ,

wherein the control device

generates cell change information indicating a change that has occurred in the cell in the culture medium based on the images, and

estimates the state of the specific medium component based on the cell change information.

3 . The culture management apparatus according to claim 2 ,

wherein the cell change information includes at least one of a change of a number of the cell and a change of a cell size.

4 . The culture management apparatus according to claim 2 ,

Wherein the control device

detects an object included in each of the images, and

generates the cell change information based on a result of the detected object.

5 . The culture management apparatus according to claim 1 ,

wherein the control device

generates medium change information indicating a change that has occurred in the culture medium based on the images, and

estimates the state of the specific medium component based on the cell change information and the medium change information.

6 . The culture management apparatus according to claim 5 ,

wherein the medium change information includes a change of color in the culture medium.

7 . The culture management apparatus according to claim 2 further comprising,

a memory device stores a learned model learned by supervised learning,

wherein the learned model learns specific medium component change information with respect to at least one of the cell change information and medium change information,

wherein the specific medium component change information indicates a change has occurred in the specific medium component,

wherein the medium change information indicates a change that has occurred in the culture medium, and

wherein the control device estimates the state of the specific medium component using the learned model.

8 . The culture management apparatus according to claim 7 ,

wherein the specific medium component change information includes at least one of a change in concentration of the specific medium component and a change in amount of the specific medium component.

9 . The culture management apparatus according to claim 1 , further comprising

a culture apparatus including a culture vessel housing the culture medium and the cell,

wherein the control device controls the culture apparatus based on the estimated state of the specific medium component.

10 . The culture management apparatus according to claim 9 ,

wherein the culture apparatus includes a supply device that supplies a predetermined substance to the culture vessel, and

wherein the control device determines a feed amount of the predetermined substance supplied from the supply device to the culture vessel based on the estimated state of the medium component.

11 . The culture management apparatus according to claim 10 ,

wherein the determined feed amount of the predetermined substance is configured to suppress a change in the state of the specific medium component.

12 . The culture management apparatus according to claim 10 ,

wherein the predetermined substance includes the specific medium component.

13 . The culture management apparatus according to claim 1 , further comprising

a display device,

wherein the control device causes the display device to display the estimated state of the specific medium component.

14 . The culture management apparatus according to claim 1 ,

wherein the control device compares the estimated state of the specific medium component and a predetermined threshold range,

wherein the control device notifies a user the comparison result.

15 . The culture management apparatus according to claim 1 , further comprising

an imaging device acquired the images of the culture medium and the cell in the culture medium.

16 . The culture management apparatus according to claim 1 ,

wherein the cell includes at least one of the cell and a cell mass.

17 . An estimation method comprising:

estimating a state of a specific medium component constituting a culture medium based on images including both the culture medium and a cell in the culture medium photographed at different times.

18 . A non-transitory computer-readable medium storing a program causing a computer to implement:

estimating a state of a specific medium component constituting a culture medium based on images including both the culture medium and a cell in the culture medium photographed at different times.
