In a minimally invasive surgical system, an image capture unit includes a prism assembly and sensor assembly. The prism assembly includes a beam splitter, while the sensor assembly includes coplanar image capture sensors. Each of the coplanar image capture sensors has a common front end optical structure, e.g., the optical structure distal to the image capture unit is the same for each of the sensors. A controller enhances images acquired by the coplanar image capture sensors. The enhanced images may include (a) visible images with enhanced feature definition, in which a particular feature in the scene is emphasized to the operator of minimally invasive surgical system; (b) images having increased image apparent resolution; (c) images having increased dynamic range; (d) images displayed in a way based on a pixel color component vector having three or more color components; and (e) images having extended depth of field.

1. An apparatus comprising: a first image capture sensor comprising a first image capture sensor surface;a second image capture sensor comprising a second image capture sensor surface, the first image capture sensor surface being in a first plane, and the second image capture sensor surface being in a second plane, wherein the first and second planes are parallel to a longitudinal axis of the apparatus;an assembly positioned to receive light, the light comprising a plurality of color components, the assembly comprising: a distal face through which the received light enters the assembly;a beam splitter configured to reflect one color component of the plurality of color components and to transmit other color components of the plurality of color components; anda surface configured to reflect the one color component, reflected by the beam splitter, in a first direction onto the first image capture sensor; anda reflective unit positioned to receive, directly from the beam splitter, the other color components, the reflective unit being configured to direct the other color components in the first direction to the second image capture sensor, wherein a first optical path length from the distal face to the first image capture sensor surface is about equal to a second optical path length from the distal face to the second image capture sensor surface. 2. The apparatus of claim 1, the first and second image capture sensor surfaces being coplanar so that the first and second planes are a same plane. 3. The apparatus of claim 1, the first and second planes being separated by a known distance. 4. The apparatus of claim 1, the first image capture sensor comprising a monochrome image capture sensor; andthe second image capture sensor comprising an image capture sensor having a color filter array for the other color components in the plurality of color components. 5. The apparatus of claim 4, wherein the one color component of the plurality of color components is a green color component; andwherein the other color components of the plurality of color components are a red color component and a blue color component. 6. The apparatus of claim 5, wherein the color filter array is a checkerboard for red and blue pixels. 7. The apparatus of claim 4, further comprising: a controller coupled to the first and second image capture sensors; the controller being configured to have full spatial resolution in the one color component of the plurality of color components; the controller being configured to have reduced spatial resolution in the other color components of the plurality of color components; and the controller being configured to generate an image having improved spatial resolution and sharpness relative to an image captured by a color image capture sensor. 8. The apparatus of claim 1, wherein the first and second image capture sensors comprise different areas of an image capture sensor chip. 9. The apparatus of claim 1, comprising an endoscope, the endoscope comprising a distal end, the distal end including the first and second image capture sensors, the assembly, and the reflective unit. 10. The apparatus of claim 1, further comprising: a stereoscopic endoscope comprising a distal end, a pair of channels, and a plurality of first and second image capture sensors, assemblies, and reflective assemblies,wherein the first image capture sensor, the second image capture sensor, the assembly, and the reflective unit are included in the plurality, andwherein each channel in the pair of channels includes, in the distal end of the stereoscopic endoscope, a different first image capture sensor of the plurality, a different second image capture sensor of the plurality, a different assembly of the plurality, and a different reflective unit of the plurality. 11. The apparatus of claim 1, wherein the assembly comprises a pentaprism. 12. The apparatus of claim 1, further comprising a stop positioned distal to the assembly and proximal to an opening in the apparatus through which the light enters the apparatus. 13. The apparatus of claim 1, the assembly and the reflective unit comprising a single integral structure. 14. The apparatus of claim 13, the single integral structure comprising a pentaprism.
