The present technology relates to an image capture device, a method of image capture, a signal processing device, a method of signal processing, and a program capable of capturing reliably a blinking image capture target. A predetermined image capture timing of an image capture unit is controlled so that image capture is performed N times during an exposure time in which at least a part of a turn-on period in which an image capture target is on overlaps with an exposure time of image capture of at least one time at a timing of dividing a blinking cycle in which the image capture target to be captured by the image capture unit configured to perform image capture at the image capture timing blinks into N equal parts where N represents more than one. The present technology is applicable to, in one example, a camera unit or the like used to capture an image.

A signal analysis device includes a synchronization data generation unit, a synchronization correction value calculation unit, and a correction unit. The synchronization unit outputs an A/D-converted correction signal as first synchronization data. The first synchronization data is associated with time based on the timing of a trigger signal input from the outside. The synchronization correction value calculation unit calculates, as a first synchronization correction value, an amplitude ratio, a phase difference, and a time difference between the first synchronization data and second synchronization data input from the outside on the basis of the first synchronization data and the second synchronization data. The correction unit corrects the amplitude, phase, and timing of the RF signal output from the object to be measured, on the basis of the first synchronization correction value or a second synchronization correction value input from the outside.

A mixer input circuit for converting a signal from a tuning section of an unbalanced type into a balanced signal and outputting the signal. In the mixer input circuit, an RF signal from an input terminal amplified by an RF amplifier is transmitted to a tuning circuit section employing a distributed constant line. A central conductor of the distributed constant line in the tuning circuit section is electromagnetically combined with a second central conductor, thereby constituting an imbalance-balance conversion section. A middle point of the second central conductor on an output side of the imbalance-balance conversion section is grounded, and a balanced output signal from both ends is transmitted to a mixer, so as to be converted into an IF signal and then to be output from an output terminal. With the present mixer input circuit, imbalance-balance conversion can be carried out without using a transformer, and a reduction in size can be realized due to the absence of deterioration of performance.
