  • the mobile terminal 2200 performs normal shooting with the areas (a, c) photographed by correcting a backlight phenomenon in one content. It provides a progressive bar 2230 that distinguishes region (b).
  • the user can more easily check whether a backlight phenomenon occurs at any moment, and it is expected that the user can use it for other editing. For example, editing can be performed quickly to delete the area where the backlight correction is performed, leaving only the part where there was no backlight phenomenon.
  • the present invention described above can be embodied as computer readable codes on a medium in which a program is recorded.
  • the computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of media that the computer can read include HDD Hard Disk Drives, SSDCS id State Disks, SD Icon Disk Drives, ROMs, RAM, CD-ROMs, magnetic tape floppy disks, and optical data storage devices. And the like also implemented in the form of a carrier wave (eg, transmission over the Internet).
  • the computer may include the controller 180 of the terminal. Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
  • the present invention can be applied to, for example, a mobile device, a television dog, a wearable device, and the like, and thus, industrial applicability is expected.
