摘要:
A heating assembly (36) for heating a cathode (38) of an electron gun (30) of an exposure apparatus (10) includes a radiation source (42) and a beam shaper (44). The radiation source (42) generates a source beam (46). The beam shaper (44) receives the source beam (46) and selectively shapes the source beam (46) into a shaped beam (48) that is directed to the cathode (38). In certain embodiments, the beam shaper (44) can readily change the shape and intensity profile of the shaped beam (48) to achieve a desired electron beam (32) from the electron gun (30). In one embodiment, the radiation source (42) generates a pulsed source beam (46).

摘要:
A group point spread function (238) for a blurry image (18) can be determined by dividing the blurry image (18) into a plurality of image regions (232), estimating a region point spread function (234) for at least two of the image regions (232); and utilizing at least two of the region point spread functions (234) to determine the group point spread function (238). The group point spread function (238) can be determined by the decomposition of the estimated region point spread functions (234) into some basis function, and subsequently determining a representative coefficient from the basis functions of the region point spread functions (234) to generate the group point spread function (238).

A system for providing an adjusted image of a scene includes an optical assembly, a capturing system coupled to the optical assembly, and a control system. The optical assembly is adjustable to alternatively be focused on a first focal area and a second focal area that is different than the first focal area. The capturing system captures a first frame of the scene when the optical assembly is focused at the first focal area, and a second frame of the scene when the optical assembly is focused at the second focal area. The first frame includes a plurality of first pixels and the second frame includes a plurality of second pixels. The control system analyzes the first frame and the second frame and utilizes graph cuts techniques to assign a depth label to at least a portion of the first frame.

A color compensation system (12) for providing an adjusted image (700) of a captured image (474) of a scene (15) that is within a fluid (16) includes compensation software (698). The compensation software (698) can adjust the captured image (474) utilizing information regarding at least one of a plurality of compensation factors that include (i) a clarity of the fluid (16), (ii) an apparatus depth of an image capturing apparatus (10), (iii) a separation distance between the image capturing apparatus (10) and a subject (20) of the scene (15), (iv) a fluid type of the fluid (16), (v) a subject depth of the subject (20), (vi) an approximate time of day the captured image (474) is captured, (vii) an approximate date the captured image (474) is captured, (viii) an approximate geographic location in which the captured image (474) is captured, (ix) an angle of incidence, and (x) an approximate weather condition in which the captured image (474) is captured. Further, the compensation software (698) can adjust the captured image (474) based on a color reference (482) positioned in the scene (15) and contained within the captured image (474) as a captured color reference image (782C).
摘要:
A capacitive sensor provides a high level of precision (potentially accurate within fractions of a nanometer) by taking the effects of environmental changes into consideration and compensating for any and all changes to the plate area and to the value of the dielectric constant before determining an accurate measurement. Such compensation can be achieved through use of a plurality of environmental sensors to mathematically calculate the change according to the variant conditions surrounding the capacitive sensor. Preferably, however, the compensation would be made through the use of a reference capacitor with a fixed gap between the plates but that is otherwise identical in both form and reaction to environmental changes as the capacitive sensor that it monitors in order to compensate for all environmental parameters other than the parameter of interest.

An image apparatus (10) for providing an adjusted image (242) of a scene (236) includes a capturing system (16) and a control system (24). The capturing system (16) captures an underexposed first frame (240) that is defined by a plurality of pixels (240A), including a first pixel and a second pixel. The first frame (240) includes at least one of a first texture region (240S) and a second texture region (240T). The control system (24) can analyze information from the pixels (240A) and determine if the first pixel has captured a portion of the first texture region (240S) or the second texture region (240T). Further, the control system (16) can analyze information from the pixels (240A) and to determine if the second pixel has captured a portion of the first texture region (240S) or the second texture region (240T). With this design, the control system (16) can reduce the noise in the first frame (240) to provide a well exposed adjusted image (242).

An image capturing apparatus (210) for capturing an image (214) of a scene (12) that is within a fluid (16) includes an apparatus frame (228), a capturing system (230), and a control system (236). The capturing system (230) captures the image (214).

Additionally, the image capturing apparatus (210) can include a depth sensor (234) that provides an apparatus depth signal that corresponds to the apparatus depth (AD) of the image capturing apparatus (210). Moreover, the image capturing apparatus (210) can include an illumination system (724) that generates a generated light beam (726) that can adjusted to compensate for the light that is attenuated by the fluid (16).

A camera (210) for providing an adjusted image (214) of a scene (12) includes an apparatus frame (224), an optical assembly (222), a capturing system (226), and a control system (232). The optical assembly (222) is adjustable to alternatively be focused on a first focal area (356A) and a second focal area (356B) that is different than the first focal area (356A). The capturing system (226) captures a first captured image (360A) when the optical assembly (222) is focused at the first focal area (356A) and captures a second captured image (360B) when the optical assembly (222) is focused at the second focal area (356B). The control system (232) provides the adjusted image (214) of the scene (12) based upon the first captured image (360A) and the second captured image (360B). Additionally, the control system (232) can perform object depth extraction of one or more objects (16) (18) (20) in the scene (12). Alternatively, the multiple captured images (360A) (360B) can be adjusted by a separate adjustment system (680).
