A multispectral image capture device includes a filter wheel (4) and an image sensor. The filters (41-46) are located close to a focusing plane of a light beam used to form the images, and at least one of the filters is more angularly narrow than the optical field of the image sensor. The production of the filter is thereby facilitated. Advantageously, the filters are closer to one another in the wheel such that multiple filters are in the optical field of the sensor simultaneously. Each multispectral image can be captured more quickly than when each filter covers the entire optical field of the sensor.
