Abstract

PURPOSE:To reduce the required space and cost of the circuit stated in the title by analogously displaying the output of a character display circuit on a screen and also color-coding the output according to a power source voltage level. CONSTITUTION:When a control switch 3 for displaying the residual capacity of a battery is pressed an A/D convertor 2 is operated by the command of a display control circuit 4 to convert the output voltage of a battery 1 into digital value. The circuit 4 reads this digital output signal 9 and outputs a display command signal 10 indicating the kind and display position of characters. Next, a character display circuit 5 accesses a stored character data memory following the signal 10 and outputs a character image signal 11. The signal 11 is input to a video signal superimposing circuit 7 and is superimposed on a video signal 6 and displayed on a screen by an image display portion 8. As display method, a method using bar graphs, that of varying numerical values and their colors according to the residual capacity of the battery, that of varying the shape, size and color of characters and figures, and the like are employed.
