Endoscope device and method for causing still image file with measurement correction data written and moving image file to be associated with each other

A file recording method performed by a processor, the file recording method comprising:

• determining whether moving image recording processing is started;
• in response to determining that the moving image recording processing is started:
• reading, from a first memory, measurement correction data corresponding to a type of an optical adapter for measurement mounted to an endoscope insertion portion,
• wherein the type of the optical adapter is determined by an adapter type determination circuit,
• wherein the measurement correction data is data used for correcting image data corresponding to an image of a subject in measurement processing, and
• wherein the image of the subject is generated by an image sensor that images the subject;
• generating a still image file including the image data corresponding to the image when the moving image recording processing is performed;
• writing the measurement correction data in the still image file;
• generating a moving image file including the image data corresponding to the image when the moving image recording processing is performed;
• and
• causing the still image file in which the measurement correction data is written, and the moving image file to be associated with each other and to be recorded in a second memory;
• in response to a state change from a first state to a second state, generating the still image file,
• wherein the first state is a state in which the optical adapter is not mounted to the endoscope insertion portion, and
• wherein the second state is a state in which the optical adapter is mounted to the endo scope insertion portion;
• measuring a time during which the optical adapter is mounted to the endoscope insertion portion;
• and
• in response to the state change occurring a plurality of times, applying a filename to a plurality of still image files generated on the basis of the plurality of times of state change, the filename including the time during which the optical adapter corresponding to each still image file included in the plurality of still image files is mounted to the endoscope insertion portion.

An endoscope device comprising:

• an endoscope insertion portion;
• an adapter type determining circuit configured to determine a type of an optical adapter for measurement mounted to the endoscope insertion portion;
• an image sensor configured to image a subject and generate an image of the subject;
• and
• a processor configured to:
• determine whether moving image recording processing is started;
• in response to determining that the moving image recording processing is started:
• read measurement correction data corresponding to the type of the optical adapter from a first memory, the measurement correction data being data used for correcting image data corresponding to the image in measurement processing;
• generate a still image file including the image data corresponding to the image when the moving image recording processing is performed;
• write the measurement correction data in the still image file;
• generate a moving image file including the image data corresponding to the image when the moving image recording processing is performed;
• and
• cause the still image file in which the measurement correction data is written, and the moving image file to be associated with each other and to be recorded in a second memory;
• in response to a remaining capacity of a buffer being smaller than a capacity required to store the image data corresponding to the image when the image data corresponding to the image is to be stored in the buffer, delete at least part of image data corresponding to a previously generated image stored in the buffer;
• in response to at least part of the image data corresponding to the previously generated image stored in the buffer being deleted, delete the still image file corresponding to the deleted image data corresponding to the previously generated image from the buffer;
• temporarily store the image data corresponding to the image and the still image file including the image data corresponding to the image in the buffer;
• and
• record the still image file stored in the buffer in the second memory.
