  • Patent number: 12225222
    Abstract: The present invention relates to an image encoding/decoding method and device. The image decoding method according to the present invention comprises the steps of: decoding a prediction mode index; determining whether the prediction mode index indicates function-based intra prediction; inducing a parameter (s) for generating a function, when the prediction mode index indicates the function-based intra prediction; generating the function on the basis of the induced parameter (s); and performing intra prediction by using the generated function.

  • Patent number: 6452143
    Abstract: A driving mechanism for linearly and reciprocatingly moving items in a heating chamber of a microwave oven is provided. The driving mechanism includes a rectangular tray for loading thereon an item to be heated within a heating chamber and a driving motor for generating a rotational force. A cam is provided for converting the rotational motion of the driving motor into a linear and reciprocating motion of the tray. The driving mechanism also includes a roller assembly mounted between the bottom of the heating chamber and the tray, the roller assembly including rollers for supporting the tray so as to linearly and reciprocatingly move the tray. Convex portions are formed on the bottom surface of the heating chamber on which the rollers move, and the tray can move in the vertical direction by means of the rollers passing over the convex portions. By moving the item both horizontally and vertically, the item can be uniformly heated, and the space within the heating chamber can be more efficiently used.
