摘要： A plenoptic otoscope enables three-dimensional and/or spectral imaging of the inside of the ear to assist in improved diagnosis of inflammations and infections. The plenoptic otoscope includes a primary imaging system and a plenoptic sensor. The primary imaging system includes an otoscope objective and relay optics, which cooperate to form an image of an inside of an ear at an intermediate image plane. The plenoptic sensor includes a microimaging array positioned at the intermediate image plane and a sensor array positioned at a conjugate of the pupil plane. An optional filter module may be positioned at the pupil plane or one of its conjugates to facilitate three-dimensional and/or spectral imaging.

摘要： Systems and methods are provided for improving the visual quality of low-resolution video displayed on large-screen displays. A video format converter may be used to process a low-resolution video signal from a media providing device before the video is displayed. The video format converter may detect the true resolution of the video and deinterlace the video signal accordingly. For low-resolution videos that are also low in quality, the video format converter may reduce compression artifacts and apply techniques to enhance the appearance of the video.

摘要： A scaler positioning module may receive a video signal selected from among a plurality of video signals. The scaler positioning module may include scaler slots for arranging the signal path of the selected video signal through at least one scaler in the scaler positioning module. The scaler slots may enable the scaler positioning module to operate in three modes. The three modes may enable the scaler positioning module to output scaled data without memory operations, scale prior to a memory write, and scale after a memory read. A blank time optimizer (BTO) may receive data from the scaler positioning module at a first clock rate and distributed memory accesses based on a bandwidth requirement determination. The BTO may access memory at a second clock rate. The second clock rate may be slower than the first which may reduce memory bandwidth and enable another video signal to access memory faster.

摘要： To improve contrast ratio of the image on a backlit display plane such as a liquid crystal display (“LCD”), each area of the image that has separately controllable backlight may be given full backlight until an average or composite brightness of the image in that area is less than a threshold value at which light leakage through the image from full-strength backlight begins to be noticable by a viewer. For image areas with composite brightness less than that threshold, backlight brightness may be reduced in proportion to how much below the threshold the area's composite image brightness is. Backlight brightness may also be adjusted for other image aspects such as (1) the presence of bright pixels in an otherwise relatively dark area, (2) whether the area is adjacent to one or more other areas in which the image information is in motion, and/or (3) time-averaging of image information over several successive frames of such information.

摘要： The adaptive contrast enhancer uses an adaptive histogram equalization-based approach to improve contrast in a video signal. For each video frame, the histogram of the pixel luminance values is calculated. The calculated histogram is divided into three regions that are equalized independently of the other. The equalized values are averaged with the original pixel values with a weighting factor that depends on the shape of the histogram. The weighting factors can be also chosen differently for the three regions to enhance the darker regions more than the brighter ones. The statistics calculated from one frame are used to enhance the next frame such that frame buffers are not required. Many of the calculations are done in the inactive time between two frames.

摘要： A system and method for enhancing the detail edges and transitions in an input video signal. This enhancement may be accomplished by enhancing small detail edges before up-scaling and enhancing large amplitude transitions after up-scaling. For example, detail edge enhancement (detail EE) may be used to enhance the fine details of an input video signal. An edge map may be used to prevent enhancing the large edges and accompanying mosquito noise with the detail enhancement. Noise may additionally be removed from the signal. After the fine details are enhanced, the signal may be up-scaled. Luminance transition improvement (LTI) or chrominance transition improvement (CTI) may be used to enhance the large transitions of the input video signal post scaler.

摘要： A multi-purpose scaler utilizes a vertical scaler module and a moveable horizontal scaler module to resample a video signal either vertically or horizontally according to a selected scaling ratio. The moveable horizontal scaler module resides in one of two slots within the multi-purpose scaler architecture to provide either horizontal reduction or horizontal expansion as desired. The multi-purpose scaler is arranged to scale the video using non-linear 3 zone scaling in both the vertical and horizontal direction when selected. The multipurpose scaler is arranged to provide vertical keystone correction and vertical height distortion correction when the video is presented through a projector at a non-zero tilt angle. The multi-purpose scaler is also arranged to provide interlacing and de-interlacing of the video frames as necessary.
