Abstract: Provided are a signal processing device, a signal processing method, a signal processing program, an imaging apparatus, and a lens apparatus capable of accurately calculating an amount of blurring on the basis of a signal which is output from a blurring detection sensor. The signal processing device processes a signal which is output from a blurring detection sensor in progress of exposure of an imaging element. The signal processing device includes a processor. The processor is configured to perform processing of generating a second signal obtained by performing high-pass filter processing on a first signal which is output from the blurring detection sensor; and processing of calculating an amount of blurring on the basis of the first signal or the second signal.

Abstract: Provided are a signal processing device, a signal processing method, a signal processing program, an imaging apparatus, and a lens apparatus capable of accurately removing an offset from an output signal of a blurring detection sensor. The signal processing device comprises the blurring detection sensor and a processor. The processor is configured to execute processing of extracting a first feature amount relating to the offset from the output signal of the blurring detection sensor, processing of integrating the output signal, processing of extracting a second feature amount relating to the offset from a value obtained by integrating the output signal, processing of calculating the offset on the basis of the first feature amount and the second feature amount, and processing of subtracting the calculated offset from the output signal.

Abstract: An imaging element unit that is built in a housing of an imaging device includes an imaging element that includes an imaging surface imaging a subject and a back surface opposite to the imaging surface, an anti-vibration function that moves the imaging element in plane directions of the imaging surface, and a first heat conductive member to which driving heat of the imaging element is conducted from the back surface and which is deformed to be capable of following movement of the imaging element caused by the anti-vibration function. The first heat conductive member includes an outer layer portion and at least one inner layer portion that is connected to the outer layer portion and is disposed in a space surrounded by the outer layer portion, and the outer layer portion and the inner layer portion include bent portions that allow the first heat conductive member to be deformable.
