Abstract

A running watch includes: a time measurement portion which measures a lapse of time; an operation button which indicates a measurement with respect to the time measurement portion; a display portion which displays a measurement result in the time measurement portion on a display screen; and a display color switching portion which switches a display color of the display screen corresponding to a measurement state of the time measurement portion.

Claims

1. An electronic device, comprising:

a measurement portion which measures a lapse of time;

a display portion which displays a measurement result measured by the measurement portion on a display screen; and

a display control portion which switches a display color of the display screen corresponding to a measurement state of the measurement portion.

2. The electronic device according to claim 1, further comprising:

an indication portion which indicates an initiation or a stop of the measurement,

wherein the measurement portion transits to a measurement state or a non-measurement state according to the indication of the indication portion, and

wherein the display control portion switches the display color to a first color when the measurement portion is in the measurement state, and switches the display color to a second color when the measurement portion is in the non-measurement state.

3. The electronic device according to claim 1,

wherein, the display control portion switches the display color of at least a part of an area of the display screen corresponding to the state of the measurement portion.

4. The electronic device according to claim 1,

wherein, the display screen includes a character area and a background area, and the display control portion switches at least one display color of the character area and the background area.

5. The electronic device according to claim 1,

wherein the display screen is displayed in white and in black, and the display control portion switches the white color and the black color to each other.

6. The electronic device according to claim 2,

wherein the indication portion indicates the stop of the measurement when the measurement portion is in the measurement state and a predetermined condition is established.

7. The electronic device according to claim 1, further comprising:

a position calculation portion which calculates positional information based on a signal from a positioning satellite,

wherein the measurement portion measures movement information based on the lapse of time and the positional information.

8. The electronic device according to claim 7,

wherein the movement information is a movement distance which considers a position where the measurement is initiated as a starting point, and

wherein the display portion displays the movement distance.

9. The electronic device according to claim 7, further comprising:

an acceleration detection portion which detects acceleration and calculates a movement amount based on the detected acceleration,

wherein the measurement portion calculates the movement distance based on the movement amount calculated by the acceleration detection portion when the position calculation portion cannot calculate the positional information.
