<p><P>PROBLEM TO BE SOLVED: To appropriately adjust an image sensor exposing time. <P>SOLUTION: A shutter blade is travelled so that light impinging on an image sensor is blocked. A predetermined amount of movement from the start of travel of a shutter is detected (time t8). A moving operation of the shutter blade is estimated on the basis of a timing of detecting the predetermined amount of the movement of the shutter blade, and a correcting amountΔT1 is set. In addition, the travel of the shutter is started at a travel start timing earlier than a basic travel start timing by a timing correcting amountΔT based on the previously set correcting amountΔT1. This makes it possible to appropriately adjust an exposure time. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
