Display device, computer program, and computer-implemented method

Abstract

A viewer terminal has: an omnidirectional image acquiring unit; an image display unit which includes a panel interface; a distortion corrected image generating unit which corrects distortion of the omnidirectional image, and generates a distortion corrected image; an operation detecting unit which, when the omnidirectional image or the distortion corrected image is displayed on the image display unit, detects an operation which is directly performed with respect to the displayed image using a panel interface and which is directed to switching between display of the omnidirectional image and display of the distortion corrected image; and an image correcting sequencer which switches between the display of the omnidirectional image and the display of the distortion corrected image according to the operation detected by the operation detecting unit.

         13 . A display device comprising:
 an image acquiring unit which acquires an omnidirectional image or a distortion corrected image obtained by correcting distortion of the omnidirectional image;   a touch panel display unit which includes a panel interface;   an operation detecting unit which, when the omnidirectional image or the distortion corrected image is displayed on the display unit, detects an operation which is directly performed with respect to a displayed image using the panel interface and which is directed to switching between display of the omnidirectional image and display of the distortion corrected image; and   a display control unit which has the display unit displays the omnidirectional image or the distortion corrected image, and switches between the display of the omnidirectional image and the display of the distortion corrected image according to the operation detected by the operation detecting unit,   wherein, when the omnidirectional image is displayed on the display unit and when the operation detecting unit detects that the omnidirectional image displayed on the display unit is pinched out, the display control unit switches the display of the omnidirectional image to the display of the distortion corrected image.   
     
     
         14 . The display device according to  claim 13 , wherein, when the distortion corrected image is displayed on the display unit and when the operation detecting unit detects that the distortion corrected image displayed on the display unit is pinched in, the display control unit switches the display of the distortion corrected image to the display of the omnidirectional image. 
     
     
         15 . The display device according to  claim 13 , wherein the distortion corrected image is a panoramic image obtained by performing panoramic expansion of the omnidirectional image based on a pinched out portion as a base line. 
     
     
         16 . The display device according to  claim 13 , wherein the distortion corrected image is a clipped image obtained by enlarging a pinched out portion. 
     
     
         17 . The display device according to  claim 13 , wherein, when the omnidirectional image is displayed on the display unit and when the operation detecting unit detects that the omnidirectional image displayed on the display unit is tapped, the display control unit has the display unit displays the distortion corrected image of a tapped portion of the omnidirectional image. 
     
     
         18 . The display device according to  claim 13 , wherein
 the display control unit determines a correction parameter of an image based on the operation detected by the operation detecting unit,   the display device further comprises an intermediate image generating unit which generates an intermediate image displayed during switching between the display of the omnidirectional image and the display of the distortion corrected image, according to the correction parameter determined by the display control unit, and   the display control unit has the display unit displays the intermediate image generated by the intermediate image generating unit during the switching between the display of the omnidirectional image and the display of the distortion corrected image.   
     
     
         19 . A computer-readable storage medium having stored therein a computer program which is executed by a display device which comprises a touch panel display unit to cause the display device to function as the display device according to  claim 13 . 
     
     
         20 . A computer-implemented method in a device which comprises a touch panel display unit which includes a panel interface, the method comprising:
 a step of, when the omnidirectional image or the distortion corrected image is displayed on the display unit, detecting an operation which is directly performed with respect to a displayed image using the panel interface and which is directed to switching between display of the omnidirectional image and display of the distortion corrected image; and   a step of switching between the display of the omnidirectional image and the display of the distortion corrected image according to the detected operation, wherein, when the omnidirectional image is displayed on the display unit and when the omnidirectional image is pinched out, the display of the omnidirectional image is switched to the display of the distortion corrected image.   
     
     
         21 . The computer-implemented method according to  claim 20 , wherein, when the distortion corrected image is displayed on the display unit and when the distortion corrected image is pinched in, the display of the distortion corrected image is switched to the display of the omnidirectional image. 
     
     
         22 . The computer-implemented method according to  claim 20 , wherein, when the omnidirectional image is displayed on the display unit and when the omnidirectional image is tapped, the display unit is caused to display the distortion corrected image of a tapped potion of the omnidirectional image.
