Abstract

An electronic device includes: a battery configured to supply electric power; a display unit configured to continually display remaining battery capacity based on battery capacity; a plurality of regions provided regarding the remaining capacity indication; and a plurality of continual functions corresponding to the respective regions. Proportional constants of the remaining capacity indication corresponding to the battery capacities of the respective regions are changed by the corresponding functions.

Claims

1. An electronic device comprising:

a battery configured to supply electric power;

a display unit configured to continually display remaining battery capacity based on battery capacity;

a plurality of regions provided regarding the remaining capacity indication; and

a plurality of continual functions corresponding to the respective regions,

wherein proportional constants of the remaining capacity indication corresponding to the battery capacities of the respective regions are changed by the corresponding functions.

2. The electronic device according to claim 1,

wherein the proportional constant to be changed is represented by a weight per a single stage of the remaining capacity indication.

3. The electronic device according to claim 1,

wherein the battery is a rechargeable secondary battery.

4. The electronic device according to claim 1,

wherein the remaining capacity indication is displayed as a percentage.

5. The electronic device according to claim 1,

wherein the plurality of functions are linear functions.

6. The electronic device according to claim 1,

wherein the plurality of regions comprise a first region, a second region, and a third region arranged in a direction from 100% to 0% of battery capacity,

wherein the proportional constant is greater than one in the first region,

wherein the proportional constant is smaller than one in the second region, and

wherein the proportional constant is made greater than one in the third region.

7. The electronic device according to claim 6,

wherein the first region is assigned to a range from 100% to 70% of battery capacity,

wherein the second region is assigned to a range from 70% to 40% of battery capacity, and

wherein the third region is assigned to a range from 40% to 0%.

8. The electronic device according to claim 1,

wherein the plurality of regions comprise a first region, a second region, and a third region arranged in a direction from 100% to 0% of battery capacity,

wherein the proportional constant is greater than one in the first region,

wherein the proportional constant is smaller than one in the second region, and

wherein the proportional constant is substantially equal to one in the third region.

9. The electronic device according to claim 8,

wherein the first region is assigned to a range from 100% to 45% of battery capacity;

wherein the second region is assigned to a range from 45% to 20% of battery capacity; and

wherein the third region is assigned to a range from 20% to 0% of battery capacity.

10. The electronic device according to claim 1,

wherein by use of the plurality of proportional constants, the battery capacity in a fully charged state matches the remaining capacity indication, and also the battery capacity in an empty state at which the electronic device can not operate matches the remaining capacity indication.
