[PROBLEMS] To detect and acquire color information of a red component (R), a green component (G), and a blue component (B) by effectively using a dynamic range of the image sensor while using a single-plate image sensor. Improve the quality of the images that are played. A light source control apparatus includes: a light source control unit that emits a plurality of narrow band light sources including at least a red light source, a green light source, and a blue light source in a time-sharing manner； and an object illuminated by light emitted from the narrow band light source. A light amount setting unit that sets the output of each of the narrow-band light sources based on image information detected in a frame-sequential manner by a monochrome single-plate image pickup device that picks up a reflected image. [Selection] Figure 7【課題】単板式の撮像素子を用いつつ、当該撮像素子のダイナミックレンジを有効活用して赤色成分（Ｒ）、緑色成分（Ｇ）、青色成分（Ｂ）の色情報をそれぞれ検出して、取得される画像の質を向上させる。【解決手段】光源制御装置は、少なくとも赤色光源、緑色光源、及び青色光源を含む複数の狭帯域光源を時分割で発光させる光源制御部と、前記狭帯域光源の出射光が照明された被写体の反射像を撮像するモノクロ型の単板式撮像素子により面順次に検出される画像情報に基づいて、それぞれの前記狭帯域光源の出力を設定する光量設定部と、を備える。【選択図】図７
