摘要： A strobe control apparatus comprises a strobe control circuit of a separately excited oscillating type, where the strobe control circuit includes a main capacitor that stores a charge for exciting a strobe, a switching device having an ON state and an OFF state, and a transformer, connected to the switching device, that generates a charging current for charging the main capacitor. The strobe control apparatus further includes a CPU that receives a first clock signal and a second clock signal different from the first clock signal, outputs a switching signal to the switching device that repeatedly switches the switching device between the ON state and the OFF state in accordance with one of the first clock signal and the second clock signal, and outputs a strobe control signal to the strobe control circuit. A first timer receives the clock signal from the first oscillator and outputs a first timer signal; a second timer receives the clock signal from the second oscillator and outputs a second timber signal, and a protection circuit switches the switching device to the OFF state in response to either the first timer signal or the second timer signal, independently of the switching signal from the CPU.

摘要： In an imaging apparatus, a first conversion unit multiplexes input signals including control signals for driving an image sensor to generate a multiplex signal having a frequency higher than those of the input signals. A transfer unit transfers the multiplexed signal generated by the first conversion unit according to low-voltage differential signaling. A reception unit receives the multiplexed signal from the transfer unit. A second conversion unit extracts the control signals for driving the image sensor from the multiplexed signal received by the reception unit. A third conversion unit performs at least one of correction processing and development processing on a signal generated by the image sensor. A signal generation unit generates and supplies processing timing control signals to the first conversion unit and the third conversion unit.
