IMAGING APPARATUS, METHOD FOR CONTROLLING IMAGING APPARATUS, AND PROGRAM

To expand a dynamic range, require only one A/D converter, and eliminate the need of high-speed drive.SOLUTION: An imaging apparatus has: exposure time control means (109) that controls the exposure time of each of areas obtained by dividing an imaging area of an image pick-up device (103) into plurality, the image pick-up device converting light into electric charges and accumulates the electric charges; gain control means (110) that controls an analog gain of output from each of the areas of the image pick-up device (103) when performing analog/digital conversion of output from each of the areas; and synchronization control means (101) that controls the synchronization between the exposure time control means (109) and the gain control means (110).SELECTED DRAWING: Figure 1 【課題】ダイナミックレンジを拡大でき、Ａ／Ｄ変換器は一つのみでよく、高速駆動も不要にする。【解決手段】撮像装置は、光を電荷に変換して蓄積する撮像素子（１０３）の撮像領域を複数に分けた領域毎の露光時間を制御する露光時間制御手段（１０９）と、撮像素子（１０３）の領域毎の出力をアナログ／デジタル変換する際に領域毎の出力のアナログゲインを制御するゲイン制御手段（１１０）と、露光時間制御手段（１０９）とゲイン制御手段（１１０）とを同期制御する同期制御手段（１０１）と、を有する。【選択図】図１
