Abstract
An electronic apparatus includes a memory storing instructions and a processor configured to execute the instructions to identify a display environment of an image, correct characteristics of a test image provided to identify a user's visual perception for characteristics of the image to correspond to the identified display environment, display the test image having the corrected characteristics on a display, and correct the characteristics of the image based on the user's adjustment input for the characteristics of the displayed test image.
Claims14
An electronic apparatus comprising:
- a display;
- an interface configured to receive an image signal;
- a memory storing instructions;
- and
- a processor configured to execute the instructions to:
- identify a display environment of an image, wherein the display environment includes display brightness of the display or ambient brightness of a surrounding environment of the electronic apparatus,
- correct characteristics of a test image provided to identify a visual perception of a user for characteristics of the image to correspond to the identified display environment, wherein the processor is configured to correct the characteristics of the test image to correspond to the display brightness or the ambient brightness,
- display the test image having the corrected characteristics on the display,
- receive an input of the user for adjusting the characteristics of the displayed test image, and
- correct the characteristics of the image based on the received input of the user for adjusting the characteristics of the displayed test image,
- wherein the processor is further configured to execute the instructions to:
- identify a first correction value in proportion to the display brightness or the ambient brightness, and reflect the first correction value in a value of the characteristics of the test image,
- correct the characteristics of the image by reflecting the first correction value and a second correction value corresponding to the input of the user for adjusting the characteristics of the displayed test image in color information of the image signal received through the interface, and
- reflect a third correction value which is in inverse proportion to the first correction value in brightness information of the image signal received through the interface.

A method of controlling an electronic apparatus, the method comprising:
- identifying a display environment of an image, wherein the display environment includes display brightness of a display of the electronic apparatus or ambient brightness of a surrounding environment of the electronic apparatus;
- correcting characteristics of a test image provided to identify a visual perception of a user for characteristics of the image to correspond to the identified display environment, wherein the correcting of the characteristics of the test image comprises correcting the characteristics of the test image to correspond to the display brightness or the ambient brightness;
- displaying the test image having the corrected characteristics on the display;
- receiving, through a touch screen of the display, an input of the user for adjusting the characteristics of the displayed test image, the input for adjusting the corrected characteristics of the displayed test image being an adjustment input of the user on the touch screen;
- correcting the characteristics of the image based on the received input of the user for adjusting the characteristics of the displayed test image;
- and
- receiving an image signal through an interface of the electronic apparatus,
- wherein the correcting the characteristics of the test image comprises:
- identifying a first correction value in proportion to the display brightness or the ambient brightness, and
- reflecting the first correction value in a value of the characteristics of the test image,
- wherein the correcting the characteristics of the image based on the received input of the user comprises:
- correcting the characteristics of the image by reflecting the first correction value and a second correction value corresponding to the input of the user for adjusting the characteristics of the displayed test image in color information of the image signal received through the interface, and
- wherein the method further comprises:
- reflecting a third correction value which is in inverse proportion to the first correction value in brightness information of the image signal received through the interface.
