Display control apparatus for displaying gain setting value in predetermined color hue
First Claim
1. A display control apparatus for displaying a gain setting value in a color hue, said display control apparatus comprising:
- an input-upper-limit setting section that sets a predetermined upper limit value of gain setting values to be input to said display control apparatus; and
a displaying-hue control section that receives a gain setting value from a variable gain control device, wherein when the received gain setting value is not greater than the predetermined upper limit value, said displaying-hue control section outputs a hue control signal to vary a displaying hue of a hue-variable display device between a predetermined first hue and a predetermined second hue in accordance with intensity of the received gain setting value, but when the received gain setting value is greater than the predetermined upper limit value, said displaying-hue control section outputs a hue control signal to set the displaying hue of the hue-variable display device to the predetermined second hue.

Abstract
Musical sound signal is input to an electronic volume control unit, which in turn adjusts the gain of the input musical signal and outputs the resultant gain-adjusted signal to an amplifier. CPU supplies the electronic volume control unit with a sound volume setting level corresponding to an output of a rotary encoder. At the same time, the CPU generates, with reference to stored data of a ROM table, a hue control signal for changing a displaying hue of a three-color light-emitting diode in accordance with the sound volume setting level supplied by the CPU. The CPU takes in a current sound volume setting level when an upper-limit setting switch is activated, and it retains the taken-in level as an upper limit value of various sound volume setting levels that are to be used to change the displaying hue of the light-emitting diode between purple and red hues. As the sound volume setting level is changed from zero to the upper limit value, the displaying hue changes in a stepwise manner.

2. A display control apparatus for displaying a gain setting value in a color hue, said display control apparatus comprising:
-
an input-range setting section that sets a predetermined lower limit value and predetermined upper limit value of gain setting values to be input to said display control apparatus; and
a displaying-hue control section that receives a gain setting value from a variable gain control device, wherein when the received gain setting value is equivalent to or greater than the predetermined lower limit value but equivalent to or smaller than the predetermined upper limit value, said displaying-hue control section outputs a hue control signal to vary a displaying hue of a hue-variable display device between a predetermined first hue and a predetermined second hue in accordance with intensity of the received gain setting value, when the received gain setting value is smaller than the predetermined lower limit value, said displaying-hue control section outputs a hue control signal to set the displaying hue of the hue-variable display device to the predetermined first hue, and when the received gain setting value is greater than the predetermined upper limit value, said displaying-hue control section outputs a hue control signal to set the displaying hue of the hue-variable display device to the predetermined second hue.
