Abstract: A method and apparatus for recognizing a protrusion on a face is proposed. The apparatus forms two images, wherein one is formed in a condition in which a target is lighted and another is formed in a condition in which the target is non-lighted. Face regions are detected from the images respectively and then are compared each other. Then, analyzing change in intensity for indicating change in contrast of the compared regions is performed. Based on the result of the analyzing, it is determined whether there is a protrusion in a face presented in the images.

Abstract: A method for adjusting an image on the basis of characteristics of a display system is provided. The image includes M horizontal lines. Each of the M horizontal lines respectively includes N pixels. Each pixel has an original gray level. A look-up table previously stores a plurality of conversion coefficients related to the characteristics of the display system. The method first calculates an ith loading according to the N original gray levels of the N pixels in the ith horizontal line. Based on the ith loading, an ith conversion coefficient corresponding to the ith loading is selected from the plurality of conversion coefficients in the look-up table. The method respectively multiplies the N original gray levels of the N pixels in the ith horizontal line by the ith conversion coefficient to generate N new gray levels for the N pixels in the ith horizontal line, whereby the image is adjusted.

Abstract: A video frame may be divided into plurality of sub-frames to reduce motion blur in sample-and-hold display. The plurality of sub-frames may preserve, in their totality, the luminance and coloring of the original input frames. An input frame that is Y?CrCb encoded may be converted to R?G?B? to enable luminance conversion onto the plurality of sub-frame while preserving the coloring information of said input frame. The first of said plurality of sub-frames may comprise energy and/or luminance encoded into the original frame with remaining energy and/or luminance encoded into remaining sub-frames. Determining luminance encoding of said plurality of sub-frames may be performed dynamically or may be determined based on programmable look-up tables. Frame conversion may compensate for nonlinearity in sample-and-hold displays that may be utilized to display the output sub-frames, wherein said nonlinearity may be caused by the gamma characteristics of said displays.

Abstract: A camera module for electronically recording images has an image sensor with a plurality of image cells. Each image cell provides an electric image signal as a function of the intensity of incident light. Each image cell has a light-sensitive element for generating a light-dependent current, as well as at least one MOS transistor which is arranged in series therewith. The gate of the MOS transistor is at a fixed potential, and the source-drain path is flowed through by the light-dependent current. In accordance with one aspect of the invention, there is arranged at least one light source in the region of the image sensor by means of which the image cells can be illuminated.

Abstract: A three-dimensional image capturing device comprises a light emitting device and an imaging device, such as a CCD, having a plurality of photo-diodes, a vertical transfer unit and a substrate. A pulse-modulated distance measuring light beam is radiated from the light emitting device to a measurement subject and a reflected light beam, generated by the measurement subject due to the distance measuring light beam, is sensed by the photo-diodes, so that a distance information sensing operation which detects distance information of the measurement subject is executed. The data, for example, relating to the distance information or the image information of the measurement subject, which is stored in the device, is transmitted to an external computer system by an optical transmission system using the above light emitting device. A data transmitting light beam may be superposed onto the distance measuring light beam.

Abstract: A method and apparatus to secure the coupler section of a trailer provides a locking device that includes a lock housing having a hitch ball element to engage the recess in the coupler, a shackle member lockable to the housing and having a bridge section that spans the hitch ball element and, and a latch assembly to latch and unlatch the shackle member. The shackle member is shown to be U-shaped with legs that extend through and secure to the lock housing. The latch assembly provides a ratchet-type engagement to allow adjustable locking. A rotatable lock mechanism drives a cam based latch mechanism between a latch state and an unlatch state.
