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.

The invention describes an observation device, having two tubular observation parts, wherein the longitudinal axes of the observation parts in the region of the ocular sides are spaced apart by a distance of at least 54 mm. At least one observation part has a flared portion on an external side, wherein the flared portion is located inside a subsection of between 20% and 80% of an overall length of the observation part. The flared portion lies in an annulus section having a normal distance to the optical axis of the objective of between 130% and 250% of the radius the objective lens.

An endoscope system includes: a generating means generating a compositing mask that serves as compositing ratios of the corresponding pixels between a pair of images acquired by simultaneously imaging two optical images having different focus positions, into which a subject image is divided on the basis of the ratios of contrasts; a correcting means subjecting compositing masks generated for pairs of images acquired in time series, to weighted averaging for respective pixels, thus generating a corrected mask; and an compositing means compositing the two images according to the corrected mask. The correcting means subjects the compositing masks to weighted averaging by performing weighting such that the percentage of the past compositing masks is higher at pixels constituting a static area and an area having contrast lower than a threshold than at pixels constituting a moving-object area or an area having contrast equal to or higher than the threshold.

A container inspection device is used to inspect containers, such as bottles or similar containers in a container filling plant. The container inspection device comprises a guide arrangement that guides characteristic information of one or more regions of a container along a first guide path to a first sensor, and along a separate, second guide path to a second sensor. The guide arrangement comprises at least two essentially identical guide structures, through which the guide paths travel. A guide element is included that is designed to guide the characteristic information to both the first guide path and the second guide path.

An optical system comprising includes an off-axis folded three mirror anastigmat (TMA) telescope including a primary mirror for receiving energy from a scene. A secondary mirror is aligned to receive reflected energy from the primary mirror. A fold mirror is aligned to receive reflected energy from the secondary mirror. A tertiary mirror is aligned to receive reflected energy from the fold mirror and to direct energy between the secondary mirror and the fold mirror. A beam splitter is aligned to receive energy reflected from the tertiary mirror, to reflect a portion of that energy to a first imaging sensor, and to pass a second portion of that energy to a second imaging sensor.
