An electronic device including a display, a memory, and a processor operatively connected to the display and the memory. The processor may be configured to: display a partial image, corresponding to a view area to be watched, in an omnidirectional image stored in the memory, on the display; select a display attribute on the basis of the distance between the view area and an area of interest in the omnidirectional image; and display additional information associated with the area of interest, on the display on the basis of the selected display attribute. Various other embodiments found through the specification are also possible.

Information displaying method and electronic device therefor

Disclosed is an electronic device comprising a communication circuit, a memory, and a processor. The processor may be set to obtain an omnidirectional image, identify at least one face in the omnidirectional image, obtain at least one gaze direction from the at least one face, and generate at least one region of interest of the omnidirectional image on the basis of the at least one gaze direction. Also, various other embodiments specified throughout the present specification may also be possible.

Method of detecting region of interest on basis of gaze direction and electronic device therefor

The present invention relates to compounds 1, 1a (S-enantiomer) and 1b (R-enantiomer) of the following formula 1, and a method for preparing the same. [formula 1] The novel compound of the formula 1 is used as an important intermediate for preparing compounds 6, 6a (S-enantiomer) and 6b (R-enantiomer) of the following formula 6, which are 2,2'-binaphthol-3-aldehyde derivatives. Also, the present invention provides a method for preparing the compound of formula 1 with a very safe method at low cost. [formula 6]

Enantiomerically pure binaphthol derivatives and method for preparing the same

The present invention relates to a method for preparing enantiomerically pure compounds 1a and 1b of the following formula 1 from racemic compound 1 of the following formula 1. [formula 1] The compounds 1a and 1b of the above formula 1 respectively are important intermediates for a process for preparing the respective compounds 2a and 2b of the following formula 2, which are 2,2'-binaphthol-3-aldehyde derivatives. The following compounds 2a and 2b are useful for preparing enantiomerically pure amino acids. The present invention provides a method for preparing the above compounds 1a and 1b very conveniently and economically, and suitably for mass production. [formula 2]
