Dot Sequential Patents (Class 348/494)
  • Patent number: 10341606
    Abstract: Systems and methods of multiplexing information from a plurality of monochrome sensors/cameras is provided. The systems and methods provided can be useful to achieve pixel-level time synchronization between information acquired by different monochrome sensors/cameras that are configured to view a scene from different viewing directions.

  • Patent number: 7408587
    Abstract: An image conversion device is provided with a first buffer area for storing either one of even field and odd field of inputted dot sequential data and a second buffer area for storing the other thereof. A data transfer control circuit controls in such a manner that, during a period in which one of the two fields is written in the first buffer area, the other field, stored in the second buffer area, is read out in a color field sequential format, and during a period in which the other field is written in the second buffer area, the other field, stored in the first buffer area, is read out in a color field sequential format. A pixel interpolating circuit carries out an insertion-interpolating process on the field read out from the image storing unit, and outputs the resulting data. Thus, it becomes possible to prevent color breaking at the time of displaying motion images on a color field sequential type display by using a buffer area having a capacity of one frame.

  • Patent number: 6459733
    Abstract: Video images including a fade transition are encoded using inter-frame prediction. A fade detector is provided to detect a fade transition by way of analyzing incoming images successively applied thereto. The fade detector generates first information indicating if the fade transition is fade-in fade-out, and also predicts fade duration and then generates second information indicating the predicted fade duration. A bit amount adjuster is provided to adjust allocated bit amount during fade using the first and second information. A motion image encoder is provided to encode the incoming images using the number of bits which has been determined by the bit amount adjuster.
