A motion image processing method and device for authenticating a user using a specific device, using motion information of an object. Time series monochrome images, obtained by photographing an object, using a camera, are input. An object is detected from an initial frame of the input time series images, using a basic shape characteristic, and a plurality of reference points to be tracked are automatically determined in the object. Then, corresponding points of the respective reference points are detected in an image frame other than the initial frame among the input time series images. Subsequently, motion information of a finger is calculated, based on the result of tracking the respective reference points and an assumption of limited motion in a 3D plane. Based on the calculated motion parameter, a solid object is subjected to coordinate conversion, and displayed if necessary. As a result of the tracking, a reference point in each frame is updated. Tracking, motion parameter calculation, and displaying are repeated with respect to subsequent frames.

The invention relates to a method and an apparatus for generating a depth map from a digital monoscopic color image. The method includes the following general steps: a) obtaining a first color component of the MCI, said first color component corresponding to partial color information of the MCI; and, b) assigning depth values to pixels of the MCI based on values of the first color component of respective pixels for forming the depth map for the MCI. In one embodiment, the depth values are generated by adjusting and/or scaling of pixel values of the Cr chroma component of the monoscopic source color image in the Y′CbCr color system.

A method for inspecting semiconductor wafers is provided in which a plurality of independent, low-cost, optical-inspection subsystems are packaged and integrated to simultaneously perform parallel inspections of portions of the wafer, the wafer location relative to the inspection being controlled so that the entire wafer is imaged by the system of optical subsystems in a raster-scan mode.

The filtered light is processed by general purpose digital-signal processors. Image subtraction methods are used to detect wafer defects, which are reported to a main computer to aid in statistical process control, particularly for manufacturing equipment.

A display provides increased contrast and resolution via first LCD panel energized to generate an image and a second LCD panel configured to increase contrast of the image. The second panel is an LCD panel without color filters and is configured to increase contrast by decreasing black levels of dark portions of images (making them blacker or darker) using polarization rotation and filtration. Preferably, the second LCD panel is of higher resolution than the first LCD panel. The panels may be directly illuminated or edge lit, and may be globally or locally dimmed monochrome or multi primary lights that may also include individual control of color intensities for each image or frame displayed. The panels may be placed in any order, but preferably are arranged such that active layers in each panel are as close together as possible. Brightness is maintained by the combination of reusing polarization between the panels and by not going through more than one set of color filters. Improved contrast is a result of using multiple light modulators in series.

A cleaning and whitening system for teeth having an electromagnetic radiation emitting toothbrush and a dentifrice with a photosensitive agent is disclosed. The toothbrush has a cleaning surface, such as bristles. The toothbrush is also adapted to direct electromagnetic radiation toward the cleaning surface. The electromagnetic radiation may be monochromatic or polychromatic. Further, the electromagnetic radiation may be substantially free of ultraviolet radiation. Additionally, the electromagnetic radiation may consist essentially of wavelengths within a range of 300 to 750 nanometers. The photosensitive agent is dispersed throughout the dentifrice. The dentifrice transmits the electromagnetic radiation through a varying thickness disposed over a target surface during use of the system. As a result, a significant portion of the photosensitive agent reacts, resulting in whitening stains, removing and/or disclosing undesired substances, and/or foaming. The dentifrice may be clear and may have clear abrasive particles. A method for tuning the cleaning and whitening system for teeth includes formulating the dentifrice with photosensitive agents that react to a range of electromagnetic radiation and providing a toothbrush that emits that electromagnetic radiation range. Another method of tuning the cleaning and whitening system includes designing a toothbrush that emits a range of electromagnetic radiation and formulating a dentifrice with photosensitive agents that react to the electromagnetic radiation range.

Pulsed illumination of different colors facilitates extraction of signals from color channels, as well as improved signal to noise ratio by combining signals of different color channels.

A display apparatus features an optical modulation device including a plurality of pixels and a pair of electrodes to which a voltage is applied, and an illumination device for illuminating the optical modulation device instantaneously and successively with a plurality of monochromatic lights of different colors in a frame period to provide a full-color image in combination with application of the voltage to the electrodes of the optical modulation device thereby effecting a full-color display over a succession of the prescribed period. A controller divides each frame period into two periods including a first period for displaying a full-color image at each pixel and a second period immediately after the first period and for placing the optical modulation device in a non-display state, thus effectively suppressing an after image phenomenon adversely affecting a full-color image display in a subsequent frame period.

A pixel image enhancement system which operates on color or monochrome source images to produce output cells the same size as the source pixels but not spatially coincident or one-to-one correspondent with them.

A rendering subsystem, responsive to the case numbers and source-pixel colors, then produces signals for driving an output device (printer or display) to display the output cells, including the inferred-edge pieces, to the best of the output device's ability and at its resolution.

An electronic endoscope system includes a video scope having a solid-state image sensor for successively producing a frame of color image-pixel signals, and an image-signal processor for producing a color video signal based on the frame of color image-pixel signals. A calculation system calculates a difference value between a value of a central single-color image-pixel signal and an average of values of one selected from single-color image-pixel signals surrounding the central single-color image-pixel signal.

An electro-optic display uses first and second drive schemes differing from each other, for example a slow gray scale drive scheme and a fast monochrome drive scheme. The display is first driven to a pre-determined transition image using the first drive scheme, then driven to a second image, different from the transition image, using the second drive scheme. The display is thereafter driven to the same transition image using the second drive scheme; and from thence to a third image, different from both the transition image and the second image, using the first drive scheme.
