Image capturing device including display control section that causes display data to be displayed in first and second display regions of display screen, and method for controlling image capturing device

An image capturing device control method comprising:

• an image data generation process that generates, by an image data generation section, captured image data showing captured image of an object per line of a display section based on output data of an image capturing sensor for capturing an image of an object;
• and
• a display control process that causes, by a display control section, each line of display data including the captured image data to be displayed on a first display region of a display screen of the display section, which is constructed by the first display region and a second display region, with a line display period having a length of “a” or more to “b” or less after a plurality of lines of the captured image data are stored in the buffer, and causes each line of display data that does not include the captured image data to be displayed on the second display region with a line display period having a length of “a”,
• “a” referring to a shortest length of the line display period corresponding to a frame rate of the display section, with the frame rate as display capability of the display section being higher than a frame rate of the image capturing sensor, and
• “b” referring to a maximum length of a period for generating one line of the captured image data in a case where the image capturing sensor is operated at the frame rate of the image capturing sensor, with “a” being shorter than “b”.

An image capturing device comprising:

• an image capturing sensor that captures and image of an object;
• an image data generation section operatively coupled to the image capturing sensor to generate captured image data showing the captured image of the object per line of a display section based on output data of the image capturing sensor;
• a buffer that stores the captured, image data;
• and
• a display control section operatively coupled to the captured image data generation section to cause display data that includes the captured image data to be displayed on a first display region of a display screen of the display section and to cause display data that does not include the captured image data to be displayed on a second display region of the display screen, wherein
• a line display period of the display section is shorter than a period for generating one line of the captured image data of in a case where the image capturing sensor is operated at a frame rate of the image capturing sensor, and
• the display control section displays the display data including the captured image data in the first display region and the display data that does not include the captured image data in the second display region of the display section at a first frame rate higher than the frame rate of the image capturing sensor after a plurality of lines of the captured image data are stored in the buffer.
