Image processing system, external device, and image processing method

An external device comprising:

• an input unit that receives image data obtained by a body-insertable apparatus including an imaging unit that captures inside of a subject;
• an orientation specifying unit that specifies orientation of the body-insertable apparatus at the time of capturing the image data with respect to a reference direction;
• a rotation correcting unit that performs rotation correction on image data which is received by the input unit on the basis of the orientation specified by the orientation specifying unit, thereby aligning orientations of a plurality of pieces of image data;
• a screen generating unit that generates a screen displaying the image data subjected to the rotation correction in the rotation correcting unit;
• and
• a rotation amount image generating unit that generates a rotation amount image visually displaying a rotation amount used for the rotation correction for each of the image data,
• wherein the screen generating unit generates the screen in which the rotation amount image generated by the rotation amount image generating unit is incorporated.

An image processing method comprising:

• receiving image data obtained by a body-insertable apparatus including an imaging unit that captures inside of a subject;
• specifying orientation of the body-insertable apparatus at the time of capturing the image data with respect to a reference direction;
• performing rotation correction on image data which is received by the input unit on the basis of the specified orientation, thereby aligning orientations of a plurality of pieces of image data;
• generating a screen displaying the image data subjected to the rotation correction;
• and
• generating a rotation amount image visually displaying a rotation amount used for the rotation correction for each of the image data,
• wherein the generating the screen includes generating the screen in which the generated rotation amount image is incorporated.

An image processing system comprising:

• a body-insertable apparatus including an imaging means for capturing inside of a subject and an output means for outputting image data obtained by the imaging means to the outside;
• and
• an external device including
• an input means for receiving the image data,
• an orientation specifying means for specifying orientation of the body-insertable apparatus at the time of capturing g the image data with respect to a reference direction,
• a rotation correcting means for performing rotation correction on image data received by the input means based on the orientation specified by the orientation specifying means, thereby aligning orientations of a plurality of pieces of image data,
• a screen generating means for generating a screen displaying the image data subjected to the rotation correction in the rotation correcting means, and
• a rotation amount image generating means for generating a rotation amount image visually displaying a rotation amount used for the rotation correction for each of the image data,
• wherein the screen generating means generates the screen in which the rotation amount image generated by the rotation amount image generating means is incorporated.
