Abstract: Imaging apparatus (100) includes selectors (115, 120) that select sound signals having a set number of channels, and a control unit. When a number of channels is set to two at time of recording sound signals, the control unit, according to a first format, records sound data generated based on selected sound signals for two channels, on one sound track included in a video file. When the number of channels is set to four, the control unit, does not record two pieces of sound data respectively on two sound tracks included in one video file in accordance with the first format.

Abstract: A digital camera includes a body that contains a CCD image sensor for capturing an object image, a monitor that is pivotably mounted relative to the body and displays an image signal relating to the object image captured by the CCD image sensor, a microphone, and a controller for changing sound pickup directivity of the microphone according to an orientation of the monitor relative to the body. This increases sound pickup sensitivity for voice-enabled shutter operation.

Abstract: An imaging device includes an optical system including a movable lens, an image capture unit configured to capture a subject image through the optical system, a sound-collecting microphone, and a control unit configured to control the optical system and the image capture unit and to receive an sound signal from the microphone. The imaging device has a first mode and a second mode as moving-image shooting modes. The control unit makes the movable lens move faster in the first mode than in the second mode when a moving image is captured. The control unit filters the sound signal with a narrower-band filter in the first mode than in the second mode.

Abstract: A digital camera includes an optical system including a focus lens, a zoom lens and a diaphragm, an HDMI output terminal configured to output sound collected by a microphone unit and a picture imaged by a CCD image sensor to an external recorder, and a controller. The controller controls switching between a moving image priority mode and a still image priority mode in which the optical system is driven at a higher speed than a speed in a moving image priority mode. In addition, the controller allows change to a moving image imaging mode by an operation unit when detecting that output to the external recorder is possible in the HDMI output terminal.

Abstract: A sound signal processing apparatus includes: first amplifier which amplifies a sound signal, depending on an input level of the sound signal; and second amplifier which amplifies with a gain the sound signal amplified by first amplifier. Second amplifier automatically decreases the gain when a level of the sound signal is greater than an upper limit threshold, and second amplifier automatically increases the gain when the level of the sound signal is lower than the upper limit threshold and when the gain is lower than a predetermined value. When second amplifier increases the gain, second amplifier changes the gain at a first speed when a user has performed an operation to decrease the input level, and second amplifier changes the gain at a second speed lower than the first speed when the user has not performed the operation to decrease the input level.

Abstract: A digital camera includes common terminal 12, mode dial 10, and function setting unit 140. Mode dial 10 is capable of setting a certain photography mode from among a plurality of photography modes including a moving image photography mode and a still image photography mode. Function setting unit 140 performs a setting so as to, when mode dial 10 sets the certain photography mode to the moving image photography mode, achieve a first function using common terminal 12, and, when mode dial 10 sets the certain photography mode to the still image photography mode, achieve a second function using common terminal 12. Function setting unit 140 does not achieve the second function in the moving image photography mode, and does not achieve the first function in the still image photography mode.
