         26 . The image acquisition device of  claim 21 , wherein the controller is further configured to control the first screen to display a black screen when the second screen is facing a user. 
     
     
         27 . The image acquisition device of  claim 26 , wherein the controller is further configured to control the first screen to display the black screen to save energy consumption. 
     
     
         28 . The image acquisition device of  claim 21 , wherein the controller is further configured to control the second screen to display a black screen when the first screen is facing a user. 
     
     
         29 . The image acquisition device of  claim 28 , wherein the controller is further configured to control the second screen to display the black screen to save energy consumption. 
     
     
         30 . The image acquisition device of  claim 21 , wherein the controller is further configured to receive a user command for changing an image displayed on the first screen or the second screen. 
     
     
         31 . The image acquisition device of  claim 30 , wherein the controller is further configured to cause the first screen to display the captured image. 
     
     
         32 . The image acquisition device of  claim 31 , wherein the controller is further configured to, in response to the user command, cause the second screen to display the captured image and cause the first screen to display a black screen. 
     
     
         33 . The image acquisition device of  claim 30 , wherein the controller is further configured to cause the second screen to display the captured image. 
     
     
         34 . The image acquisition device of  claim 33 , wherein the controller is further configured to, in response to the user command, cause the first screen to display the captured image and cause the second screen to display a black screen. 
     
     
         35 . The image acquisition device of  claim 30 , wherein the first screen is a touch screen device and receiving the user command comprises the controller detecting a touch input on the first screen. 
     
     
         36 . The image acquisition device of  claim 35 , wherein the touch input corresponds to an operation by a user forming a touch path. 
     
     
         37 . The image acquisition device of  claim 36 , wherein receiving the user command further comprises the controller determining whether the touch path matches a predetermined path. 
     
     
         38 . The image acquisition device of  claim 37 , wherein the controller is configured to control the first screen and the second screen based on determining that the touch path matches the predetermined path. 
     
     
         39 . The image acquisition device of  claim 30 , wherein receiving the user command comprises detecting a touch input on the first screen when the first screen is displaying a black screen. 
     
     
         40 . The image acquisition device of  claim 30 , wherein receiving the user command comprises detecting a touch input on the second screen when the second screen is displaying a black screen.
