## Abstract

An electronic camera includes an imager. An imager repeatedly outputs an electronic image corresponding to an optical image captured on an imaging surface. A displayer displays the electronic image outputted from the imager, in parallel with a process of the imager. An adjuster adjusts an imaging condition based on the electronic image outputted from the imager when a specific key is transitioned to a first operation state. A recorder records the electronic image outputted from the imager under the imaging condition adjusted by the adjuster, in response to transition of the specific key to a second operation state. A stopper stops the imager and/or the displayer during a period of non-operation of the specific key when a battery voltage falls below a first reference value.

## Claims

### Claim 1

An electronic camera, comprising:
an imager which repeatedly outputs an electronic image corresponding to an optical image captured on an imaging surface;
a displayer which displays the electronic image outputted from said imager, in parallel with a process of said imager;
an adjuster which adjusts an imaging condition based on the electronic image outputted from said imager when a specific key is transitioned to a first operation state;
a recorder which records the electronic image outputted from the imager under the imaging condition adjusted by said adjuster, in response to transition of said specific key to a second operation state; and
a stopper which stops said imager and/or said displayer during a period of non-operation of said specific key when a battery voltage falls below a first reference value.

### Claim 2 (depends on 1)

An electronic camera according to claim 1, further comprising:
a shielder which shields an incident light on said imaging surface;
a driver which drives said shielder in association with a process of said recorder; and
a restrictor which restricts a process of said driver when the battery voltage falls below a second reference value smaller than the first reference value.

### Claim 3 (depends on 2)

An electronic camera according to claim 2, wherein said imager adopts a rolling shutter system as an exposure system.

### Claim 4 (depends on 1)

An electronic camera according to claim 1, wherein said specific key is equivalent to a shutter button, and the first operation state and the second operation state are respectively equivalent to a half-depressed state and a fully-depressed state.

### Claim 5

An imaging control program recorded on a non-transitory recording medium in order to control an electronic camera provided with an imager which repeatedly outputs an electronic image corresponding to an optical image captured on an imaging surface; and a displayer which displays the electronic image outputted from said imager, in parallel with a process of said imager, the program causing a processor of the electronic camera to perform the steps comprising:
an adjusting step of adjusting an imaging condition based on the electronic image outputted from said imager when a specific key is transitioned to a first operation state;
a recording step of recording the electronic image outputted from the imager under the imaging condition adjusted by the adjusting step, in response to transition of said specific key to a second operation state; and
a stopping step of stopping said imager and/or said displayer during a period of non-operation of said specific key when a battery voltage falls below a first reference value.

### Claim 6

An imaging control method executed by an electronic camera provided with an imager which repeatedly outputs an electronic image corresponding to an optical image captured on an imaging surface; and a displayer which displays the electronic image outputted from said imager, in parallel with a process of said imager, comprising:
an adjusting step of adjusting an imaging condition based on the electronic image outputted from said imager when a specific key is transitioned to a first operation state;
a recording step of recording the electronic image outputted from the imager under the imaging condition adjusted by the adjusting step, in response to transition of said specific key to a second operation state; and
a stopping step of stopping said imager and/or said displayer during a period of non-operation of said specific key when a battery voltage falls below a first reference value.
