The invention provides an image sensing device for capturing a gray level image and a chromatic image on a frame via a mixing illumination of a first light and a second light. The image sensing device includes a color filter array module and a controlling module. The color filter array module includes a first filter unit, a second filter unit, a third filter unit, and a fourth filter unit. The first filter unit is used to sense a first pixel data at the frame the second filter unit is used to sense a second pixel data at the frame the third filter unit is used to sense a third pixel data at the frame and the fourth filter unit is used to sense a narrow-band data. The controlling module controls the sensing and illuminating form of the color filter array module according to the first light or the second light. An image processing system reconstructs the full scale chromatic image and gray barrow-band image respectively after color filter array demosaicking process and synthesizes the chromatic image and narrow-band image into a color narrow-band image.本發明提供一種影像感測裝置,透過第一光源及第二光源混合照明於一畫面讀取灰階影像及彩色影像。影像感測裝置包含彩色濾光陣列模組及控制模組。彩色濾光陣列模組包含第一濾光單元、第二濾光單元、第三濾光單元及第四濾光單元。第一濾光單元用以感測該畫面之第一像素資料,第二濾光單元用以感測該畫面之第二像素資料,第三濾光單元用以感測該畫面之第三像素資料,第四濾光單元用以感測該畫面之窄波段像素資料。控制模組用以根據第一光源或第二光源以控制彩色濾光陣列模組的感測與照明形態。影像處理系統在經過彩色濾光陣列解馬賽克後可重建全尺寸的彩色與灰階窄波段影像,並且可將彩色與灰階窄波段影像合成為一彩色的窄波段影像。4...影像感測裝置40...彩色濾光陣列模組42...第一光源44...第二光源46...控制模組6...影像處理系統60...影像解碼賽克模組68...資料處理裝置
