    摘要: In a camera having a focus detection device which detects a focus state of an object at a plurality of focus detection spots in an imaging area, there are provided an operation portion which selects an arbitrary focus detection spot in the imaging area, and a setting portion which sets the focus detection spot selected by the operation portion as a focus detection spot group. A signal used to set a focus state of the focus detection spot in the thus set group is output by an AF sensor, an arithmetic operation portion detects the focus state of the focus detection spot based on an output from this AF sensor, and a lens drive portion drives a focus optical system to adjust its focus based on a detection result of the focus state obtained by the arithmetic operation portion.

    摘要: Two systems each having an audio signal output unit are docked together, and audio signals are controlled in accordance with the characteristics of each system to thereby output sounds of good quality. If sounds are output from the two systems at the same time, the frequency band or sound volume of the audio signal is controlled in accordance with the characteristics of each speaker to thereby output sounds easy to listen.

    摘要: An illumination optical apparatus for setting the illuminance on an illuminated object as high as possible at or below the upper limit of illuminance. When the illumination state changing unit changes the illumination state of illumination light, for example, when the numerical aperture is decreased to lower the illuminance on the illuminated object, the power supplied to the light source is increased; inversely, when the numerical aperture is increased to enhance the illuminance on the illuminated object, the power supplied to the light source is decreased so that the illuminance is kept at or below the predetermined upper limit. This can maintain the illuminance on the illuminated object high and nearly constant even with a change of the illumination state.
