SHAKE DETECTION SENSOR UNIT, OPTICAL INSTRUMENT, IMAGING APPARATUS, AND SHAKE DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To detect shake amount information in a wide detection range without increase in communication amount, when outputting the shake amount information via serial interface communication.SOLUTION: A shake detection sensor unit comprises: shake detection means 205 for outputting an analog signal with a detected shake amount; AD conversion means 206 for converting the analog signal output by the shake detection means to a digital signal; and arithmetic means 207 which outputs via serial interface communication the difference between an AD converted value at the time of last sampling by the AD conversion means and that at this-time sampling, as a signal expressing the shake amount.
