Progressive To Interlace Patents (Class 348/446)
  • Patent number: 7834934
    Abstract: When television screen setting is not set and thus a television screen setting completion flag is not set, and a terminals-connection judgment pin takes a low level, an i/p selection screen is initially displayed on a progressive display device. However, the i/p selection screen is not displayed on an interlaced display device. When processing performed for the i/p selection screen is completed, or when the terminals-connection judgment pin takes a high level, indicating that the video input D-terminal of the display device is not connected to the video output D-terminal, an aspect ratio setting screen is displayed. After aspect ratio setting is completed, the television screen setting completion flag is set. This eliminates the need to perform the television screen setting again.

  • Publication number: 20100265392
    Abstract: Uncompressed video information is transmitted over a wireless communication medium from a wireless sender device to a wireless receiver device. Progressive transmission data rate adaptation is performed on original uncompressed video pixel information. The progressive transmission data rate adaptation is performed on selected pixel information to obtain a rate-reduced pixel information. The rate-reduced pixel information requires a lower transmission data rate than the original frame. The rate-reduced pixel information is transmitted over the wireless communication medium to the wireless receiver device. At the receiver, a reverse operation is performed to recover the original uncompressed video pixel information.

  • Patent number: 7227541
    Abstract: An image display apparatus has an image display including scanning lines, modulation lines and display devices driven through the scanning lines and modulation lines, a scanning circuit for supplying a scanning signal to the scanning line, a modulating circuit for supplying a modulation signal to the modulation line, and a converting circuit for converting the number of scanning lines of an input image signal. In addition, a selecting section selects a scan method of any of a first scan method and a second scan method and a changing section changes a vertical scaling filter characteristic of the converting circuit in accordance with the selected scan method. The vertical scaling filter characteristic in the case of the first scan method is a characteristic having a weaker elimination effect on high frequency components as compared with the vertical scaling filter characteristic in the case of the second scan method.

  • Patent number: 7218343
    Abstract: In an image sensing apparatus using a non-interlace scanning type image sensing element, image data as well as a signal indicating whether the image data is sensed in a mode which is suitable for sensing a moving image (field image sensing mode) or sensed in a mode which is suitable for sensing a still image (frame image sensing mode) are recorded in a recording medium. In reproducing the image data from the recording medium, in a case where the recorded image data is sensed in the frame image sensing mode and a moving image output is required, an interpolation filter controller controls an interpolation filter to generate and output field images interpolated between consecutive frame images on the basis of the reproduced even or odd line field image data of the two consecutive frame images, thereby obtaining a smooth moving image.

  • Patent number: 7176930
    Abstract: The present invention provides a system, method and computer program product for reducing fill and improving quality of interlaced displays using multi-sampling. In an embodiment of the invention, a frame buffer for a interlaced display is filled. Initially, a first multi-sample of the first line of the first field is calculated. The bottom sub-pixels of the first multi-sample are the top sub-pixels of a multi-sample of the first line of the second field. The first multi-sample is written into the frame buffer. Then, a second multi-sample of the second line of the first field is calculated. The top sub-pixels of the second multi-sample are the bottom sub-pixels of a multi-sample of the first line of the second field. Also, the bottom sub-pixels of the second multi-sample are the top sub-pixels of the second line of the second field. The second multi-sample is written into the frame buffer.

  • Patent number: 7142223
    Abstract: A de-interlacing methodology generates frames from interlaced video signals by incorporating data from multiple fields into an interpolation-based de-interlacing process. Pixels directly above and below a blank pixel location and pixels immediately before and after the blank pixel location (in the fields immediately preceding and following, respectively, the blank pixel field) can be used to interpolate a pixel value for the blank pixel location. The use of pixel data from multiple fields improves the resolution of the interpolation process, thereby improving output frame accuracy. Adjacent pixel values can also be adjusted to further improve the consistency of the visual display provided by the output frames.
