obtaining orientation information by a first sensor and motion information of an apparatus itself by a device; calculating a portion of an abdominal outline by the processor, based on the orientation information and the motion information; calculating shape characteristics based on the calculated portion of the abdominal outline by the processor; estimating, based on the shape characteristics, at least one of a visceral fat area and a subcutaneous fat area of an abdominal cross-section by the processor; and displaying an abdominal CT sample image corresponding to the estimated at least one of the visceral fat area and the subcutaneous fat area from among the plural abdominal CT sample images on a display by the processor. ### Claim 2 (depends on 1) The method of displaying an image of an abdominal cross-section according to claim 1, further comprising: displaying an abdominal CT sample image corresponding to the estimated visceral fat area and the subcutaneous fat area on a display. ### Claim 3 A display apparatus that displays an image of an abdominal cross-section comprising: a storage that stores plural abdominal CT sample images which have at least either of different visceral fat areas or different subcutaneous fat areas; a first sensor configured to obtain orientation information of an apparatus itself; a device configured to obtain motion information of the apparatus itself; a processor communicatively coupled with the storage, the first sensor, and the device, the processor configured to estimate, based on shape characteristics of a portion of an abdominal outline calculated based on the orientation information and the motion information, at least one of a visceral fat area and a subcutaneous fat area of an abdominal cross-section; and a display communicatively coupled with the processor, the display configured to display an abdominal CT sample image corresponding to the estimated at least one of the visceral fat area and the subcutaneous fat area from among the plural abdominal CT sample images. ### Claim 4 (depends on 3) The display apparatus that displays an image of an abdominal cross-section according to claim 3, wherein an abdominal CT sample image corresponding to the estimated visceral fat area and the subcutaneous fat area is displayed on the display by the processor. ### Claim 5 (depends on 3) The display apparatus that displays an image of an abdominal cross-section according to claim 3, wherein the first sensor includes an orientation sensor, an angular velocity sensor, or an inclination sensor. ### Claim 6 (depends on 3) The display apparatus that displays an image of an abdominal cross-section according to claim 3, wherein the device includes a second sensor communicatively coupled with the processor, the second sensor configured to obtain the motion information of the apparatus itself. ### Claim 7 (depends on 5) The display apparatus that displays an image of an abdominal cross-section according to claim 5, wherein the device includes a second sensor communicatively coupled with the processor, the second sensor configured to obtain the motion information of the apparatus itself. ### Claim 8 (depends on 6) The display apparatus that displays an image of an abdominal cross-section according to claim 6, wherein the second sensor includes an acceleration sensor or an electronic tape measure. ### Claim 9 (depends on 3) The display apparatus that displays an image of an abdominal cross-section according to claim 3, wherein the device includes a timer. ### Claim 10 (depends on 5) The display apparatus that displays an image of an abdominal cross-section according to claim 5, wherein the device includes a timer. ### Claim 11 (depends on 6) The display apparatus that displays an image of an abdominal cross-section according to claim 6, wherein the device includes a timer. ### Claim 12 (depends on 8) The display apparatus that displays an image of an abdominal cross-section according to claim 8, wherein the device includes a timer. ### Claim 13 A display system that displays an image of an abdominal cross-section comprising: a storage that stores plural abdominal CT sample images which have at least either of different visceral fat areas or different subcutaneous fat areas; a first sensor configured to obtain orientation information of an apparatus itself; a device configured to obtain motion information of the apparatus itself; a processor communicatively coupled with the storage, the first sensor, and the device, the processor configured to estimate, based on shape characteristics of a portion of an abdominal outline calculated based on the orientation information and the motion information, at least one of a visceral fat area and a subcutaneous fat area of an abdominal cross-section; and a display communicatively coupled with the processor, the display configured to display an abdominal CT sample image corresponding to the estimated at least one of the visceral fat area and the subcutaneous fat area from among the plural abdominal CT sample images.
