Terminal apparatus, backlight emission method and computer readable medium for terminal apparatus
First Claim
1. A terminal apparatus comprising:
- input keys configured to detect pressing conducted thereon respectively;
key backlights each of which emits a plurality of colors of light to shine corresponding one of the input keys; and
a backlight controller configured to control the plurality of colors of light independently for each of the key backlights,wherein the backlight controller causes the key backlights to emit light of a first color in a case where an input key out of the input keys detects pressing thereon, and changes an emission color of a key backlight corresponding to the input key detecting the pressing from the first color to a second color when a state of the pressing becomes a predetermined state after the input key has been kept pressed without bring released for a predetermined time interval, and returns the emission color of the key backlight to the first color when the input key is released.

Abstract
The terminal apparatus includes input keys configured to detect pressing conducted thereon respectively, key backlights each of which emits a plurality of colors of light to shine corresponding one of the input keys, and a backlight controller configured to control the plurality of colors of light independently for each of the key backlights. The backlight controller causes the key backlights to emit light of a first color in a case where an input key out of the input keys detects pressing thereon, and changes an emission color of a key backlight corresponding to the input key detecting the pressing from the first color to a second color when a state of the pressing becomes a predetermined state.

11. A non-transitory computer readable medium having stored thereon a program which, when executed by a computer, causes a computer to function as a terminal apparatus,
the terminal apparatus comprising: -
input keys configured to detect pressing conducted thereon respectively; key backlights each of which emits a plurality of colors of light to shine corresponding one of the input keys; and a backlight controller configured to control the plurality of colors of light independently for each of the key backlights, wherein the backlight controller causes the key backlights to emit light of a first color in a case where an input key out of the input keys detects pressing thereon, and changes an emission color of a key backlight corresponding to the input key detecting the pressing from the first color to a second color when a state of the pressing becomes a predetermined state after the input key has been kept pressed without bring released for a predetermined time interval, and returns the emission color of the key backlight to the first color when the input key is released. - View Dependent Claims (12, 13, 14, 15)
