    • An image pickup apparatus which is capable of preventing light diffraction from being caused by a density step or a thickness step of a filter, thereby preventing degradation of resolution during still image shooting, and securing the dynamic range of exposure control during both moving image shooting and still image shooting. In the image pickup apparatus, an image pickup element converts light incident thereon from a lens into an electric signal. A diaphragm mechanism changes the amount of light incident on the image pickup element. An ND filter covers an aperture of the diaphragm mechanism such that the aperture can be opened and closed, thereby adjusting the amount of light incident on the image pickup element after passing through the aperture. A controller controls a closing operation of the ND filter for closing the aperture, such that the closing operation is performed at different speeds between when a gradation portion of the ND filter covers the aperture and when a transparent portion of the ND filter covers the aperture.

    • When a wiper is started, a wiper arm is moved at first in the backward path direction (S1). If a motor is locked (S2) before an original point position signal is outputted, a reciprocating operation for moving the wiper arm temporarily in the forward path direction and then moving the wiper arm again in the backward path direction is performed (S5-S8, S1). When an absolute position signal is not outputted even after repeating the reciprocating operation a plurality of times (S5) and the original point position cannot be recognized (S2, S5), the motor is not forced furthermore but stopped (S5→END) On the other hand, if the motor is not locked when the wiper arm is moved in the backward path direction (S1) and the original point position can be recognized (S2, S3), wiping control is performed (S4) by calculating the wiper arm position based on the original point position and the motor rotation pulse.

    • There are included a first quadrature modulation part (5) that divides an input signal into an I signal and a Q signal having a phase orthogonal to the phase thereof and uses a baseband frequency to perform frequency conversions of the I and Q signals, thereby performing a quadrature modulation; and a second quadrature modulation part (8) that uses in-phase and quadrature carriers of FM frequencies, which are 90 degrees out of phase with respect to each other, to perform frequency conversions of the I and Q signals, which are generated by the first quadrature modulation part (5), thereby performing a quadrature modulation. Thus, the phases of the I and Q signals, which are shifted by 90 degrees with respect to each other by the first quadrature modulation part (5), are further shifted by 90 degrees with respect to each other by the second quadrature modulation part (8), thereby providing frequency components the phases of which have been inverted, whereby the unwanted harmonic components at the spurious sides of a target frequency can be attenuated.
