Imaging apparatus
An imaging apparatus includes an imaging unit operable to capture a subject image via an optical system and generate image data, a regulating unit operable to regulate an exposure amount for the imaging unit; a shake detector operable to detect a shake of the imaging apparatus; an operation unit capable of being in a first operating state and a second operating state; and a controller operable to control the recording unit to record the image data generated by the imaging unit in the recording medium, when the operation unit is in the first operating state. The controller determines whether or not the operation unit is in the second operating state before the first operating state, and regulates an exposure time of the regulating unit based on the determination result and the shake of the imaging apparatus detected by the shake detector.
1. An imaging apparatus comprising:
an imaging unit operable to capture a subject image via an optical system and generate image data;
a recording unit operable to record the image data generated by the imaging unit in a recording medium;
a regulating unit operable to regulate an exposure amount for the imaging unit;
a shake detector operable to detect a shake of the imaging apparatus;
an operation unit capable of being in a first operating state and a second operating state; and
a controller operable to control the recording unit to record the image data generated by the imaging unit in the recording medium, when the operation unit is in the first operating state,
wherein the controller determines whether or not the operation unit is in the second operating state before the first operating state, and regulates an exposure time of the regulating unit based on the determination result and the shake of the imaging apparatus detected by the shake detector so that exposure time to be regulated, when it is determined that the operation unit is not in the second operating state before the first operating state, is shorter than an exposure time to be regulated when it is determined that the operation unit is in the second operating state before the first state.
2. The imaging apparatus according to claim 1 , wherein the controller regulates the exposure time based on the determination result and the shake of the imaging apparatus detected by the shake detector when the operation unit is in the first operating state.
3. The imaging apparatus according to claim 1 , wherein the controller regulates the exposure time so that the exposure time becomes shorter as the shake of the imaging apparatus detected by the shake detector is larger.
4. The imaging apparatus according to claim 1 , further comprising an illuminance acquiring unit operable to acquire information about illuminance of the subject from the image data, wherein
the controller regulates the exposure time, based on the illuminance as well as the determination result and the shake of the imaging apparatus detected by the shake detector.
5. The imaging apparatus according to claim 1 , wherein the controller regulates the exposure time, based on a focal distance defined by the optical system as well as the determination result and the shake of the imaging apparatus detected by the shake detector.
6. The imaging apparatus according to claim 1 , wherein the second operating state of the operation unit is a state to instruct start of an autofocus operation.
7. The imaging apparatus according to claim 1 , wherein the controller sets a lower limit of a settable shutter speed for regulating the exposure time.
8. The imaging apparatus according to claim 1 , wherein the shake detector detects shake before the operation unit is operated by a user.
9. An imaging apparatus comprising:
an imaging unit operable to capture a subject image via an optical system and generate image data;
a recording unit operable to record the image data generated by the imaging unit in a recording medium;
a regulating unit operable to regulate an exposure amount for the imaging unit;
an acquiring unit operable to acquire information about a shake of the imaging apparatus;
an operation unit capable of being in a first operating state and a second operating state; and
a controller operable to control the recording unit to record the image data generated by the imaging unit in the recording medium, when the operation unit is in the first operating state,
wherein the controller determines whether or not the operation unit is in the second operating state before the first operating state, and regulates an exposure time of the regulating unit based on the determination result and the information about the shake of the imaging apparatus acquired by the acquiring unit so that exposure time to be regulated, when it is determined that the operation unit is not in the second operating state before the first operating state, is shorter than an exposure time to be regulated when it is determined that the operation unit is in the second operating state before the first operating state.
10. An imaging apparatus comprising:
an imaging unit operable to capture a subject image via an optical system and generate image data;
a recording unit operable to record the image data generated by the imaging unit in a recording medium;
a regulating unit operable to regulate an exposure amount for the imaging unit;
an operation unit capable of being in a first operating state and a second operating state; and
a controller operable to control the recording unit to start recording of the image data generated by the imaging unit in the recording medium, when the operation unit is in the first operating state,
wherein the controller determines whether or not the operation unit is in the second operating state before the first operating state, and regulates an exposure time of the regulating unit based on the determination result so that exposure time to be regulated, when it is determined that the operation unit is not in the second operating state before the first operating state, is shorter than an exposure time to be regulated when it is determined that the operation unit is in the second operating state before the first operating state.
11. The imaging apparatus according to claim 1 , wherein the controller detects whether or not the operation unit is in the second operating state at predetermined times, and when it is sequentially detected a predetermined number of times that the operation unit is in the second operating state, the controller determines that the operation unit is in the second operating state.
