  • Patent number: 10277905
    Abstract: Blocks of a frame of a non-baseband video signal are encoded by selecting between a staircase- or sinusoidal-based transform. For each prediction mode, a prediction block for encoding a current block is generated, a residual block is generated, the residual block is transformed using a sinusoidal-based transform and using a staircase-based transform, and first and second rate-distortion value for encoding the residual block using the sinusoidal-based transform and staircase-based transform are respectively generated. One of the staircase-based transform or the sinusoidal-based transform for encoding the residual block is selected based on a lowest value of the first rate-distortion value and the second rate-distortion value among results for each prediction mode, and the current block is encoded using the selected one of the staircase-based transform or the sinusoidal-based transform.

  • Patent number: 9973661
    Abstract: An interlaced video signal can include content of different types, such as interlaced content and progressive content. The progressive content may have different cadences according to the ratio between the frame rate of the progressive content and the field rate of the interlaced video signal. Cadence analysis is performed to identify the cadence of the video signal and/or to determine field pairings when progressive content is included. As described herein, motion information (e.g. motion vectors) for blocks of fields of a video signal can be used for the cadence analysis. The use of motion information provides a robust method of performing cadence analysis.

    Abstract: The present invention relates to a system, a device, and vehicle for recording panoramic images. According to the present invention, panoramic images can be obtained using a plurality of optical cameras and light directing elements which are arranged based on a parabola. This allows a compact device to be obtained while ensuring that each camera records a partial image as if it were at substantially the same focus point as the other cameras. By arranging the plurality of cameras and light directing elements such that the respective focus points are slightly offset relative to each other, a slight overlap between adjacent field of views can be obtained to improve stitching of the partial images to from the panoramic image.

  • Patent number: 9536290
    Abstract: Some embodiments provide a novel method for tempering an adjustment of an image to account for prior adjustments to the image. The adjustment in some embodiments is an automatic exposure adjustment. The method performs an operation for a first adjustment on a first set of parameters (e.g., saturation, sharpness, luminance). The method compares the first set of parameters to a second set of parameters to produce a third set of parameters that expresses the difference between the first adjustment and a second adjustment. The method performs a third operation to produce an adjusted image. The first set of parameters quantify a set of prior adjustments to the image by an image capturing device when the image was captured in some embodiments. The second set of parameters is a set of target parameters. The third set of parameters specify the tempered adjustment of the image.

  • Patent number: 8259172
    Abstract: The picture input section 12 fetches image data from the storage device 11, and then, inputs image data on sequential n images into the section 13 for measuring correlation between sequential images and the section 14 for measuring correlation between sampled images. The section 13 for measuring correlation between sequential images measures the correlation between sequential images based on video data. The section 14 for measuring correlation between sampled images measures the correlation between sub-sampled images. The short shot determining section 15 determines short cut points by using the correlation between the sequential images and the correlation between the sub-sampled images. Otherwise, short cut points may be determined in consideration of motion amount between the sequential images or the sub-sampled images.

  • Patent number: 8102419
    Abstract: An improved method and apparatus for scanning of anamorphic film utilizes increased number of scans and combination of scan lines for video output generation. A progressive raster scan is made of the film and stored in a frame memory. The spacing between the scan lines is made smaller than for the conventional scanning of an anamorphic image. In the preferred embodiment, the spacing between the scan lines for a 2:1 anamorphic image equals the spacing for scanning of a non-anamorphic image. The scan lines are retrieved from the memory and combined, preferably with the two nearest neighbors of the scan line. Optionally, the combined lines are weighted, preferably with the center scan line having larger weight. Subsequent video output lines are formed by repeating the process. Progressive video output or interlace output is provided as desired.

  • Patent number: 8004607
    Abstract: In a method for detecting the cadence of a sequence of images, each pixel in each current field in the sequence of images is compared to at least one pixel in at least one previous field. A pixel motion phase value is assigned to each pixel in the field as a function of the result of that comparison. For each block of pixels in the current field, a block motion phase value is determined from the motion phase values of the pixels in the block. The current field is segmented into at least one region, with each region comprising a whole number of blocks, as a function of at least the determined block motion phase values. A region motion phase value is assigned to each region, based on the block motion phase values for the blocks in the region.

  • Patent number: 7986340
    Abstract: A lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, is operative for causing selected pixels in a raster pattern of scan lines to be illuminated to produce an image of high resolution in color. The direction of scanning of the scan lines is switched between alternate frames, and the resulting image is the superposition of successive frames integrated for viewing by the human eye.

  • Patent number: 7898599
    Abstract: The present invention is generally directed to automated methods and systems for converting image streams having a first frame rate to a second frame rate without the need for user intervention. Embodiments of the present invention obviate the effects of processing of a telecine process. In one embodiment, where frames are encoded by a single video field, a statistical analysis of the differences between adjacent frames reveals a telecine pattern, thereby identifying which frames to remove. In another embodiment, where frames are encoded by even and odd video fields, which are interleaved to produce the frame, a statistical analysis of the differences between adjacent fields reveals the telecine pattern, identifies which frames to remove, and identifies frames that are candidates for re-interleaving.
