A pulse oximeter may reduce power consumption in the absence of overriding conditions. Various sampling mechanisms may be used individually or in combination. Various parameters may be monitored to trigger or override a reduced power consumption state. In this manner, a pulse oximeter can lower power consumption without sacrificing performance during, for example, high noise conditions or oxygen desaturations.

A three-dimensional sense adjusting unit displays three-dimensional images to a user. If a displayed reaches a limit of parallax, the user responds to the three-dimensional sense adjusting unit. According to acquired appropriate parallax information, a parallax control unit generates parallax images to realize the appropriate parallax in the subsequent stereo display. The control of parallaxes is realized by optimally setting camera parameters by going back to three-dimensional data. Functions to realize the appropriate parallax are made into and presented by a library.

Method and apparatus for processing three-dimensional images

A system, including apparatuses, software and methods, is disclosed for capturing and delivering images as to which various interactive functions are enabled for a user. The images introduced to the system can come from any one of a variety of sources, including from a digital camera. A graphical user interface permits a user to customize a set of interactive functions to be enabled for a given set of images. The interactively enabled images can be delivered via a webpage to a user, for example, via email, the Internet or downloaded from a disk or from disk drive on a computer on which the webpage is stored. Each image is delivered to a user in its own layer of software, which permits complex sets of images of relatively high resolution to be delivered to users without any appreciable delay associated with the delivery or the need for the user to have additional software, such as a plug-in to receive images and enable interactive functions with respect to the images. Whenever an interactive function is being carried out, a viewer perceives only one image layer at a given time, but the currently viewable image layer can be changed rapidly, so that the user can perceive the illusion of motion, including virtual rotation of an object depicted in a set of images.

System for delivering and enabling interactivity with images

A mobile computing device can comprise a microprocessor, a display, at least one motion sensor, and an imaging device including a two-dimensional image sensor and an imaging lens configured to focus an image of a target object on the image sensor. The mobile computing device can be configured to periodically display a preview image frame of the target object. The mobile computing device can be further configured to compensate for a movement of the imaging device relatively to the target object during a time period elapsed between taking and displaying the preview image frame, by transforming the preview image frame based on the device movement detected by the motion sensor.

Gaming systems and methods where qualification for play of a bonus game is linked to play of a base game. Multiple players may qualify for the bonus game by achieving preselected criteria associated with play of the base game. The qualified players may participate in the bonus game and achieve a bonus game outcome based on the player's skill or strategy. The bonus game outcome may allow the player to accumulate bonus awards. In addition, the bonus game outcome may impede or terminate the player's movement in the bonus game. Each player's movement in the bonus game may depend on his or her continued play in the base game. Each qualified player may also eliminate other qualified players by occupying the same space in the bonus game.

An image reproducing method and apparatus whereby an image with a wide angle of visibility can be reproduced from a holographic stereogram in a manner less susceptible to blurring. For reproducing an image from a holographic stereogram 80 of an edge lit system, a holographic stereogram 80 is arranged on a lateral side of a cylindrically-shaped light-introducing block 81 and a reproducing illuminating light beam 82 is illuminated on the holographic stereogram 80 via the light-introducing block 81. A reproduced image 85 is produced by a diffracted light beam obtained on diffraction of the reproducing illuminating light beam 82 transmitted through the holographic stereogram 80.

An image data generating method for generating image data corresponding to a planar holographic stereogram is provided, in which a parallax image string imaging system for producing a parallax image string may be reduced in size and in which there is no necessity for using a larger image angle of the imaging device and unneeded image data may be diminished to enable effective data utilization. An image data converting method is also provided in which image data of an image recorded on a holographic stereogram may be promptly produced from plural images from which the holographic stereogram is derived. First, an object or an imaging device is rotated, while the distance between the object and the imaging device is kept substantially constant, for shooting plural images of different viewing angles by the imaging device. The image data of plural images as shot is then corrected for keystone distortion. The image data corrected for keystone distortion is then processed with viewing point conversion processing for converting the viewing point for generating image data of images recorded on the holographic stereogram. In addition, image data including the information for, plural images is compressed for storage in the internal storage device of the computer. With the image data having been read into the internal storage device, only the image data of an image required for image data conversion processing of generating image data of the image recorded on a holographic stereogram is expanded for executing image data conversion processing operations.

An image recording apparatus and an image recording method can be suitably used for preparing a large number of edge-lit type holograms or holographic stereograms in a simple manner by copying. A hologram recording medium 11 is applied onto a principal surface 10 a of a light-introducing block for copying 10 and held in contact with a master 15 . Then, reference light L equivalent to reproducing light for reproducing the image of the master 15 is introduced into the light-introducing block for copying 10 through an end face thereof 10 b.

An apparatus capable of converting motion image data, which is captured in an ordinarily way without intending to produce a parallax image printed matter, to data that can be printed as a parallax image printed matter is provided. The apparatus includes the steps of specifying at least one frame as a reference frame from a plurality of frames constituting the motion image data, and setting a point-of-regard on an object in the reference frame, calculating an amount of movement of the point-of-regard using a relation between the point-of-regard in the reference frame and a point corresponding thereto in another frame, obtaining a motion compensation amount for each frame based on this amount of movement thereof, and executing a motion compensation processing for the motion image data based on the motion compensation amount, thereby converting the motion image data to parallax image data.
