Display apparatus and process method for display apparatus

A method performed by a display apparatus, the method comprising:

• obtaining, for a target video source currently played by a display of the display apparatus, signal source information and type information, the signal source information describing a signal source of the target video source and the type information describing a type of the target video source, wherein the type of the target video source comprises at least one of a Dolby type, a high-dynamic range (HDR) type, or a standard dynamic range (SDR) type;
• determining a set of picture modes corresponding to the target video source according to the signal source information and the type information of the target video source, wherein different combinations of the signal source and the type of the target video source correspond to different sets of picture modes, and wherein the signal source comprises at least one of an external apparatus interface or an network application, a first set of picture modes corresponding to the external apparatus interface being different from a second set of picture modes corresponding to the network application, each picture mode defining a pre-set of image adjustment parameters;
• presenting the set of picture modes corresponding to the target video source in a picture mode list on the display, presenting the set of picture modes comprising based on determining that the type of the target video source is the HDR type, presenting one or more of an HDR standard mode or an HDR theater mode in the picture mode list;
• obtaining, based on a selection of a target picture mode from the set of picture modes presented in the picture mode list, image adjustment parameters corresponding to the target picture mode;
• and
• adjusting image quality of the target video source played on the display according to the image adjustment parameters.

An apparatus having a remote controller associated therewith to control the apparatus, comprising:

• a display, configured for presenting one or more images from a broadcast system or a network or one or more user interfaces;
• a memory, configured to store instructions;
• and
• at least one processor, in connection with the display and the memory, and configured to execute the instructions to cause the apparatus to perform:
• obtaining, for a target video source whose content being presented on the display, signal source information and type information, the signal source information describing a signal source of the target video source and the type information describing a type of the target video source;
• presenting a set of picture modes corresponding to the target video source in a picture mode list on the display, wherein the set of picture modes determined based on the signal source information and the type information of the target video source, wherein a first set of picture modes corresponding to a first combination of the signal source and the type of the target video source is different from a second set of picture modes corresponding to a second combination of the signal source and the type of the target video source, each picture mode defining a pre-set of image adjustment parameters, wherein presenting the set of picture modes comprises based on determining that the type of the target video source is a high-dynamic range (HDR) type, presenting one or more of an HDR standard mode or an HDR theater mode in the picture mode list;
• determining, based on a selection of a target picture mode from the set of picture modes presented in the picture mode list, image adjustment parameters corresponding to the target picture mode;
• and
• adjusting the display to present the target video source according to the image adjustment parameters.
