The resulting image may be scaled to any bit-level as desired, such as 8-bit. Next, the normalized image is mapped into a domain such that ghosting is aligned along a single dimension of the 2D image array. Examples of well known computing devices that may be suitable include, but are not limited to, personal computers, server computers, hand-held or laptop devices for example, media players, notebook or tablet or slate computers, cellular phones, personal data assistants, voice recorders , multiprocessor systems, microprocessor-based systems, set top boxes, game consoles, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, computers with multi-touch input devices, and the like. Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks DVD or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can accessed by computing machine The uses of the corrected image, include, for example but not limited to, an object recognition system or a display An increase in this peak pointing angle can imply a larger apparent aperture width, and thus smaller diffraction envelope.

Communications connection s is an example of communication media.
Referring now to FIG. Do you already have an account? Here my has a “ghost sticker” on the lens barrel face and the beauty ring is painted flat black and the chrome beauty ring is painted with Sharpie–whyI could see it in my photos. Next, an anti-ghost point spread antighozt is specified and deconvolved from the image.
Both measured and simulated responses of the turning film in response to light are shown in FIG. Artifacts also can be induced by diffuse layers in an optical system.

The function may be determined from ray tracing data for the wedge design, by determining bounce points along the wedge, or by mathematically determining bounce points and then fitting the bounce antigghost relation to a curve. Next, an anti-ghost point spread filter is created and deconvolved. Use of LED illumination, compared to laser illumination, allows for more broadened spectral width, thus more overlap in diffraction orders, and may result in a more curved profile in the PSF compared to use of narrow wavelength band sources.
As apparent aperture increases, the diffraction envelope decreases in angular width. In its xntighost basic configuration, computing machine typically includes at least one processing unit and memory You must log in or sign up to reply here. I often just color the front of the lens barrel with Sharpie permanent marker and I have painted them with flat black paint vilter.
Rotation error representing rotation of the camera imager chip may be corrected by a rotation prior to distortion correction. It is anrighost that other embodiments may be utilized and structural changes may be made without departing from the scope of the disclosure.

An increase in this peak pointing angle can imply a larger apparent aperture width, and thus smaller diffraction envelope. The resulting image may be scaled to any bit-level as desired, such as 8-bit.
The computing system environment is only one example of a suitable computing environment and is not intended to suggest any limitation as to the scope of use or functionality of such a computing environment. Apparent radius due to wedge optics is defined as follows:.
This example creates an anti-ghost PSF having an effective ghost spacing of 51 pixels in the non-linear amtighost image, and includes correction for 2 subsequent ghost bounces due to a wedge angle in the range between 1 and 2 degrees.
A light ray increase by twice the wedge angle for each bounce off the face opposing the exit face of the wedge as it approaches the escape angle.

In another implementation, diffraction due to a turning film layer is corrected by a deconvolution of the diffraction pattern due to the turning film layer. The diffraction pattern due to the turning film interacting with a single beam of laser light, shown in FIG. And ruin your shot. The escaping light is then collected by a camera lens that directs light to a camera sensor. By removing the artifacts computationally instead of optically, manufacturing costs and complexity are reduced over prior solutions.
Having now described an example implementation, a computing environment in which iflter a system is designed to operate will now be described. filted
Alternatively, a direct measurement of the angular exit profile of the layer may be made, to serve as a PSF representing the angular exit profile of the layer. Alternatively, or in addition, the functionally described herein can be performed, at least in part, by one or more hardware logic components.
Such a panel can be of small size, on order of a couple of inches diagonal, to larger sizes, on order of forty inches and larger. A wedge serves as an angle-space to position-space converter, because angular field-of-view FOV at the wedge thick-end window corresponds to position space across the wedge face.

The wedge-based imaging system of claim 18wherein processing the image further comprises:
