PROBLEM TO BE SOLVED: To easily set a lighting field of AEC (automatic exposure control) in long-length imaging.SOLUTION: A lighting field selecting circuit selects AEC detection signals from detection pixels used for AEC on the basis of a spine lighting field map 85 for defining parts such as spine and waist as lighting field regions 87, 88 or a lower extremity lighting field map 86 defining parts such as waist, both knees and both ankles as lighting field regions 89, 90, 91. The maps 85, 86 each are scaled up and down by a map scaling section so as to have the same size as an actual long-length imaging range, divided by a map dividing section so as to be an imaging range of each shot, and then outputted to the lighting field selecting circuit.COPYRIGHT: (C)2013,JPO&INPIT【課題】長尺撮影時のAECの採光野を簡便に設定する。【解決手段】採光野選択回路は、脊椎と腰部にあたる部分を採光野領域87、88として規定した脊椎用採光野マップ85、または腰部、両膝、両くるぶしにあたる部分を採光野領域89、90、91として規定した下肢用採光野マップ86に基づき、AECに用いる検出画素からのAEC検出信号を選別する。各マップ85、86は、実際の長尺な撮影範囲と同じサイズになるようマップ拡縮部で拡縮され、各回の撮影範囲と同じサイズになるようマップ分割部で分割されて採光野選択回路に出力される。【選択図】図8
