Abstract
An endoscope system includes an endoscope, which includes an instruction unit that issues a selection condition switching instruction and a still image storage instruction and which images a subject, and a processor. The processor acquires an endoscope image for each frame, temporarily stores the endoscope image selected based on a first selection condition or a second selection condition in a temporary storage area, performs image evaluation to assign an image evaluation value for each of the temporary storage images, and stores, based on the still image storage instruction, an optimal still image selected in accordance with the image evaluation value.
Claims18
An endoscope system comprising:
- an endoscope that images a subject;
- and
- a processor,
- wherein the endoscope includes an operation part,
- the processor is configured to:
- acquire an endoscope image obtained by imaging the subject with the endoscope for each frame;
- temporarily store the endoscope image selected based on a first selection condition or a second selection condition in a temporary storage area as a temporary storage image;
- perform image evaluation to assign an image evaluation value for each of the temporary storage images temporarily stored in the temporary storage area;
- switch between the first selection condition and the second selection condition based on a user-issued selection condition switching instruction input through the operation part;
- and
- store, based on a user-issued still image storage instruction input through the operation part, an optimal still image selected in accordance with the image evaluation value from the temporary storage images,
- the processor is configured to temporarily store the selected endoscope image in the temporary storage area as the temporary storage image such that the number of temporarily storage images does not exceed a predetermined maximum number,
- the first selection condition includes:
- a first A selection condition, which is applied in a case where the temporary storage image is temporarily stored in the temporary storage area in a number less than the maximum number, temporarily storing the endoscope image in the temporary storage area as the temporary storage image in an order of most recent imaging time until the maximum number is reached;
- and
- a first B selection condition, which is applied in a case where the maximum number of temporary storage images are temporarily stored in the temporary storage area, deleting the temporary storage image with an oldest imaging time, among the temporary storage images temporarily stored in the temporary storage area, from the temporary storage area and then temporarily storing the endoscope image in the temporary storage area as the temporary storage image in the order of the most recent imaging time, and
- the second selection condition includes:
- a second A selection condition, which is applied in a case where the temporary storage image is temporarily stored in the temporary storage area in a number less than the maximum number, temporarily storing the endoscope image in the temporary storage area as the temporary storage image in an order of most recent imaging time until the maximum number is reached;
- and
- a second B selection condition, which is applied in a case where the maximum number of temporary storage images are temporarily stored in the temporary storage area, leaving only a proper still image selected in accordance with the image evaluation value from the temporary storage images in the temporary storage area as the temporary storage image and deleting an image except for the proper image from the temporary storage area, and then performing the second A selection condition.

An operation method for an endoscope system including an endoscope, which includes an operation part and images a subject, and a processor, the operation method comprising:
- causing the processor to execute:
- acquiring an endoscope image obtained by imaging the subject with the endoscope for each frame;
- temporarily storing the endoscope image selected based on a first selection condition or a second selection condition in a temporary storage area as a temporary storage image;
- performing image evaluation to assign an image evaluation value for each of the temporary storage images temporarily stored in the temporary storage area;
- switching between the first selection condition and the second selection condition based on a user-issued selection condition switching instruction input through the operation part;
- and
- storing, based on a user-issued still image storage instruction input through the operation part, an optimal still image selected in accordance with the image evaluation value from the temporary storage images,
- wherein the method comprises causing the processor to execute temporarily storing the selected endoscope image in the temporary storage area as the temporary storage image such that the number of temporarily storage images does not exceed a predetermined maximum number,
- the first selection condition includes:
- a first A selection condition, which is applied in a case where the temporary storage image is temporarily stored in the temporary storage area in a number less than the maximum number, temporarily storing the endoscope image in the temporary storage area as the temporary storage image in an order of most recent imaging time until the maximum number is reached;
- and
- a first B selection condition, which is applied in a case where the maximum number of temporary storage images are temporarily stored in the temporary storage area, deleting the temporary storage image with an oldest imaging time, among the temporary storage images temporarily stored in the temporary storage area, from the temporary storage area and then temporarily storing the endoscope image in the temporary storage area as the temporary storage image in the order of the most recent imaging time, and
- the second selection condition includes:
- a second A selection condition, which is applied in a case where the temporary storage image is temporarily stored in the temporary storage area in a number less than the maximum number, temporarily storing the endoscope image in the temporary storage area as the temporary storage image in an order of most recent imaging time until the maximum number is reached;
- and
- a second B selection condition, which is applied in a case where the maximum number of temporary storage images are temporarily stored in the temporary storage area, leaving only a proper still image selected in accordance with the image evaluation value from the temporary storage images in the temporary storage area as the temporary storage image and deleting an image except for the proper image from the temporary storage area, and then performing the second A selection condition.
