  Real image type finder optical system - Patent 5245469
A real image type finder optical system according to claim 1 or 3 wherein the surface of said reticle is composed of pyramids disposed continuously and said pyramids are formed so as to have center axes having inclination angles relative to an optical axis progressively larger as said pyramids are farther from the optical axis.
In this real image type finder optical system, a light bundle which is emitted from the object toward the photographic lens 1 emerges from the photographic lens 1, and then is reflected by the quick return mirror 2 and imaged on the focal plane 9a of the reticle 9.
The pentagonal prism 6 inverts the image formed on the focal plane 9a of the reticle 9 in both the vertical and horizontal directions and the eyepiece lens 7 correct aberrations such as spherical aberration, whereafter the image formed on the focal plane 9a is reimaged on the retina of the photographer.

For example, the image produced by the refraction of light rays by a convex lens (when the distance between the object and the lens is greater than the focal length of the lens) is real, and it appears on the side of the lens opposite the one on which the object is present.
Images of the same size as the object are sometimes produced, as in the case of the plane mirror, but in other cases they are larger, and in still others, smaller.
The size of the image and whether it is erect or inverted, real or virtual, depend on the distance of the object from the lens or mirror relative to the focal length and on the type of lens or mirror (plane, convex, or concave) employed.

A third characteristic of plane mirror images pertains to the relationship between the object's distance to the mirror and the image's distance to the mirror.
A fourth and final characteristic of plane mirror images is that the dimensions of the image are the same as the dimensions of the object.
Images formed by plane mirrors are virtual, upright, left-right reversed, the same distance from the mirror as the object's distance, and the same size as the object.

 Images, real and virtual   (Site not responding. Last check: 2007-10-17)
Real images are those where light actually converges, whereas virtual images are locations from where light appears to have converged.
Real images occur when objects are placed outside the focal length of a converging lens or outside the focal length of a converging mirror.
Ray tracing gives the position of the images by drawing one ray perpendicular to the lens, which must pass through the focal point, and a second ray that passes through the center of the lens, which is not bent by the lens.

 Realty Times: Realty Reality: Public Image of Real Estate Agents
Real estate professionals are entitled to feel good about the fact that members of the general public appear to think more highly of them than they used to.
Not only have real estate agents gained three points over the past 5 years, but also they have "moved up the ladder," passing occupations that once were above them on the scale of ethics perceptions.
Gallup doesn't deal with the Realtor®/non-Realtor® distinction; it just asks about "real estate agents." Given, though, that the vast majority of active real estate agents are in fact Realtors, one would have to think that this couldn't have made much difference.

 A Real Image
This type of image is called a real image, in contradistinction to the virtual images we've studied before.
The distinction between a real image and a virtual image is an important one, because a real image can projected onto a screen or photographic film.
If a piece of paper is inserted in figure (e) at the location of the image, the image will be visible on the paper (provided the object is bright and the room is dark).

 Real image - Wikipedia, the free encyclopedia
In optics, a real image is a representation of an actual object (source) formed by rays of light passing through the image.
Real images can be produced by concave mirrors and converging lenses.
This, the image that we see on the other side of the lens or mirror plane, is known as virtual image.

 Topic 18. Real and Virtual images; plane mirrors
The image may be smaller or larger; it may be erect or inverted – it is the one-to-one relationship between the image and the object that is important.
The reflected rays preserve the size and shape of the object, so that the magnification (the ratio of the size of the image to the size of the object) is always 1.
The image point I always appears to be the same distance behind the mirror as the object point O is in front of it.

 Real-Time Image Segmentation for Image-Guided Surgery
Advances in image-guided surgery techniques have made it possible to acquire images of a patient whilst the surgery is taking place, to align these images with high resolution 3D scans of the patient acquired preoperatively and to merge intraoperative images from multiple imaging modalities.
Intraoperative MR images are acquired during surgery for the purpose of guiding the actions of the surgeon.
In order to successfully segment intraoperative images we have developed a new image segmentation algorithm that takes advantage of an existing preoperative MR acquisition and segmentation to generate a patient specific model for the segmentation of intraoperative data.

 Real World Image Sharpening Tips From Expert Bruce Fraser > Traditional Prepress Sharpening   (Site not responding. Last check: 2007-10-17)
Inappropriate sharpening is extremely hard to undo, and unless the images are scanned to their final output resolution, any sharpening applied during the scan is almost guaranteed to be inappropriate.
Since traditional sharpening, as it is commonly use today, is sensitive neither to image content nor to final use, it's common to see grossly over-sharpened images, especially in the case where a sharpened scan receives a second round of sharpening at final output size.
Failure to take image content into account in the first round of sharpening typically results in applying the wrong kind of sharpening for the image, so wanted detail may be obscured and unwanted detail or noise may be exaggerated.

 Mars Global Surveyor MOC2-283 Release
Viking orbiter images acquired in 1976 showed that one of thousands of buttes, mesas, ridges, and knobs in the transition zone between the cratered uplands of western Arabia Terra and the low, northern plains of Mars looked somewhat like a human face.
On that date at 20:54 UTC (8:54 p.m., Greenwich time zone), the MGS was rolled 24.8° to the left so that it was looking at the "face" 165 km to the side from a distance of about 450 km.
An earlier picture obtained in June 2000 was combined with the new, April 2001 image, to produce a stereo ("3-D") view of the western portion of the hill ("3-D" glasses with red for left eye and blue for right eye are needed to view the anaglyph).

The image position may be found from the lens equation or by using a ray diagram.
If the lens equation yields a negative image distance, then the image is a virtual image on the same side of the lens as the object.
The lens equation can be used to calculate the image distance for either real or virtual images and for either positive on negative lenses.

 Stop misleading 'Image Stabilization' labels: Digital Photography Review
However one thing which has become annoying is the increasing use of the label 'Image Stabilization' or 'Anti-Shake' to describe nothing more than a (noisy) high sensitivity mode.
In our product database we only give a 'yes' flag to those cameras which implement image stabilization in the true sense, as either stabilization of a lens element or of the sensor itself (on a shifting platform) which allow you to take a blur free shot at slower shutter speeds.
We would like to see an end to the use of the word 'Image Stabilization' where no physical stabilization mechanism (lens shift or sensor shift) exists, a better description would be 'Low Light mode' or 'High Sensitivity mode'.

A real Atari disk is a complex mess of adhesive magnetic stuff, made sense of by a dedicated floppy disk controller and then made useable by a computer in the disk drive.
An ATR disk image contains 16 bytes of data that identify it as an Atari disk image, and the remainder is every byte of useable data off the original diskette, stored in the original order it was stored on the disk.
This image is similar to the ATR but lacks the ID and format header, it is essentially a large unmarked blob of data.

We see that there will be similar triangles if we assume both the object and image are perpendicular to the axis, and if we assume the lens is thin and the light doesn't deviate from a straight line very far.
It is easy to see that if the real image is formed further from the lens than the object is placed, the image will also be larger.
