Sample image analyzer, sample image analyzing method, and control method for object stage of sample image analyzer

A sample image analyzer, comprising:

• an object stage configured to support a sample carrier;
• an imaging device comprising a lens set and a camera and configured to capture an image of an object in a sample carried by the sample carrier;
• a driving device configured to drive the object stage and the imaging device to move relative to each other;
• a control device, which establishes communication connection with the imaging device and the driving device and is configured to control the driving device to deliver the sample carrier to a position below the imaging device, wherein the control device is further configured to:
• control the driving device to drive the object stage and the imaging device to move horizontally and vertically relative to each other;
• control the imaging device to capture, at least during the relative vertical movement, a plurality of images of the a same object within a field of view at different horizontal positions and at different vertical positions;
• and fuse the plurality of images of the same object to obtain a target image of the same object.

A sample image analyzer, comprising:

• an object stage configured to support a sample carrier;
• a sample imaging device configured to capture an image of an object in a sample carried by the sample carrier;
• a mode setting device configured to set one of a first capturing mode and a second capturing mode as an operation mode in which the sample imaging device and the object stage move relative to each other and the sample imaging device performs capturing;
• and
• a control device configured to:
• when an operation mode instruction of the first capturing mode is received, control the sample imaging device to capture a plurality of images of a same object at a same horizontal position and at different vertical positions, and fuse the plurality of images of said same object to obtain a target image of said same object;
• and when an operation mode instruction of the second capturing mode is received, control the sample imaging device to capture a plurality of images of a same object at different horizontal positions and at different vertical positions, and fuse the plurality of images of said same object to obtain a target image of said same object.

A sample image analyzer, comprising:

• an object stage configured to support a sample carrier;
• a sample imaging device configured to capture an image of an object in a sample carried by the sample carrier;
• a mode setting device configured to set one of a third capturing mode and a fourth capturing mode as an operation mode in which the sample imaging device and the object stage move relative to each other and the sample imaging device performs capturing;
• and
• a control device configured to:
• when an operation mode instruction of the third capturing mode is received and, when an object within a field of view of the sample imaging device is changed from a first object to a second object, control the sample imaging device and the object stage to stop moving horizontally relative to each other, control the sample imaging device and the object stage to move vertically relative to each other, and control the sample imaging device to capture a plurality of images of the second object during the relative vertical movement;
• and when an operation mode instruction of the fourth capturing mode is received and, when an object in a field of view of the sample imaging device is changed from a first object to a second object, control the sample imaging device and the object stage to continue to move horizontally and vertically relative to each other, and control the sample imaging device to capture a plurality of images of the second object during the relative horizontal movement and the relative vertical movement.
