Abstract: In a lens-interchangeable digital camera having a half mirror arranged in a shooting optical path and capable of displaying a live view, the half mirror is made movable between a position inserted into the shooting optical path and a position retracted from the shooting optical path, and when power-on is detected, the movable half mirror is returned to the position in the shooting optical path, while when power-off is detected, the movable half mirror is retracted from the shooting optical path. Further, upon detecting the mounting state of a lens barrel, when removal of the lens barrel is detected, the movable half mirror is retracted, while when mounting of the lens barrel is detected, the movable half mirror is returned.

Abstract: There is disclosed a single-lens reflex camera which does not drive a movable reflecting mirror when it enters a shooting operation while a live view is being displayed. For example, the rotation direction of a motor controlling the driving of shutter charge and a movable reflecting mirror can differ between a live view state and the other states. Then, a transmission mechanism for transmitting a driving force from the motor to the movable mirror is configured to release its engagement between the motor and the movable mirror when the motor rotates in a direction for the live view state.

Abstract: A digital camera is disclosed which has a first recording medium for recording captured images and a second recording medium, different from the first recording medium, for recording images obtained after editing the captured images.

Abstract: The present invention discloses a finder device capable of adjusting the amount of light emitted from a light-emitting display section arranged in the device according to the light-receiving level of an image pickup device. The amount of light emitted is adjusted, for example, so that the light-receiving level of the image pickup device is not saturated. The light-emitting display section can be configured, for example, to include a LED display element for projecting light onto a mat screen in the finder device and a drive circuit that can adjust the amount of LED light, or to include an LCD display unit provided adjacent to the mat screen and a backlight unit that can adjust the amount of light for the LCD unit.

Abstract: The present invention discloses a finder device and camera including the finder device having an information display device arranged near a mat screen on which a subject image is formed, and an imaging device for acquiring a finder image including the subject image on the mat screen. In this structure, the operation of the information display device is stopped in response to the imaging operation of the imaging device. This can prevent the subject image and the image displayed by the information display device from being difficult to see due to the difference between the brightness of the image on the mat screen and the brightness of the information display device. The information display device can be configured such that it superimposes, for example, shooting information and focus points on the image.

Abstract: A digital camera includes a first imaging section for acquiring subject image data, a movable mirror for guiding the light beam of the subject to a finder optical system, and a second imaging section for capturing the subject image data in the finder optical system. In this structure, the image acquired by the first imaging section and the image acquired by the second imaging section are switched and selectively displayed depending on the movement of the movable mirror. For example, the digital camera can be configured such that the first imaging section is used to acquire a shot image and the second imaging section is used to acquire a live image.

Abstract: A data recording apparatus comprises a plurality of recording media, data generating means for generating recording data, recording means for, whenever the recording data is generated from the data generating means, allocating and recording the recording data in the plurality of recording media, and data transfer means for integrating, into one recording medium, the plurality of recording data recorded in a distributed manner in the plurality of recording media, when the data generating means and the recording means are not in operation.

Abstract: A shutter abnormality detection apparatus for a camera includes a shutter including leading and trailing curtains which are shutter curtains electrically controlled to run. A curtain run detection unit detects a run state of at least one of the leading and trailing curtains. A curtain run time judgment unit judges a run time of the shutter curtains based on an output from the curtain run detection unit. An abnormality processing unit notifies an abnormality state of the shutter curtains, when it is judged as a result of judgment in the curtain run time judgment unit that the curtain run time is abnormal.
