    摘要： The invention relates to an optical assembly (100), an image processing apparatus (130), a method for recording a digital multispectral color image (136) and a method for retrieving left and right stereoscopic color images (122, 124, 300, 402) from the digital multispectral color image, resulting in a highly flexible, inexpensive and easy-to-use way to generate stereoscopic color images. The multispectral color image is recorded using an optical band-pass filter (104) having filter sectors(200, 202, 302, 400) the filter sectors having different image-separating pass-bands (216). The stereoscopic color images are recorded in a color space (RGB) comprising color channels (R, G, B), wherein each color channel overlaps at least one image-separating pass-band per filter sector. An image sensor (112) or a camera (113) comprises spectral bands (224) at each pixel (148) that match the image-separating pass bands, thus allowing to encode the stereoscopic channels in a multispectral color image. The image processing apparatus is configured to extract the stereoscopic color images from the digital multispectral color image.

    摘要： An image acquisition system includes a plurality of illumination sources, each configured to emit light having a specified central wavelength, a first light sensing element having a first field of view and configured to receive illumination reflected from a portion of a surgical site, a second light sensing element having a second field of view and configured to receive illumination reflected from a second portion of the surgical site, and a computing system. The computing system is configured to receive data from the first light sensing element and from the second light sensing element, compute imaging data based on the data received from the first and second light sensing elements, and transmit the imaging data for receipt by a display system. The second field of view may overlap at least a portion of the first field of view. A control system of the image acquisition system may function similarly.
