摘要:
A video coding device comprising: lower-layer coding means for coding a video sequence at a lower frame rate; upper-layer coding means for coding one or more specified part-areas of the video sequence at a higher frame rate; and synthesizing means for synthesizing a video sequence of the upper-layer with a video sequence of the lower-layer by using part-area-information representing the specified part-area; characterized in that the synthesizing means generates a lower-layer frame for synthesizable frame in absence of the lower-layer frame corresponding to the temporal position of the synthesizable frame in order to fill the absence, by using the lower-layer frame existing temporally before the synthesizable frame and a second part-area-information of a lower-layer frame existing temporally after the synthesizable frame, and by using the lower-layer frame existing temporally after synthesizable frame for a portion of only the first part-area, and by using the lower-layer frame existing temporally before the synthesizable frame for a portion of only the second part-area. A corresponding decoding device is also provided.
摘要:
In a video coding device capable of making coded data have a hierarchical structure, a specified area of each frame is selected, the position and the shape of the selected area are encoded, a pixel value of the selected area is encoded as lower-layer coded data, a pixel value of a whole image is encoded as first upper-layer coded data by using pixel values of already decoded images of the lower-layer and the first upper layer and a pixel value of the selected area is encoded as second upper-layer coded data by using pixel values of already decoded images of the lower-layer and the second upper layer. By the video coding device and video decoding device mentioned above, decoding a part of coded data makes it possible to reproduce only a selected area of a lower image-quality or reproduce a whole image of a lower image-quality or reproduce a whole image with a selected area of a higher image-quality and other areas of a lower image- quality. In encoding and decoding a background video-sequence and a plurality of foreground part-video- sequences, a coding device (101, 102, 103, 122, 123, 120) encodes position information of part-video-sequences and a decoding device (105, 106, 107, 108, 109, 110, 124, 125, 121) prepares weight values necessary for weighted-mean image synthesizing on the basis of the coded data of the position information data, whereby each part-video-sequences is synthesized with the background video-sequence by using the weighted mean values. And in laying a plurality of part-video-sequences over a background video-sequence by using weighted mean values, an amount of coded data can be reduced because the weighted mean values are prepared from binarized information. Furthermore, a synthesized video-sequence has a smoothed boundary between the part images and the background image can be smoothly synthesized without any visual defect since the weighted mean data prepared from the binarized information gets a value of 0 to 1. In synthesizing an lower-layer frame from preceding and proceeding lower-layer frames by using a first part-area-information and a second part-area-information of lower-layer frames existing temporally before and after the synthesizable frame, the temporally preceding and proceeding lower-layer frames previously averaged with weight is used for synthesizing an overlapped portion of a first part-area with a second part-area or an area not belonging to the first part-area and the second part-area on the synthesizable frame, the temporally proceeding lower-layer frame used for synthesizing an area belonging to the first part-area only and the temporally preceding lower-layer frame is used for synthesizing an area belonging to the second part-area only. By the video coding device and video decoding device with the synthesizing method as above described, the synthesyzing image is free from the distortion occurred in the prior art image aforementioned.

A sensor based automated cooking apparatus (2) is provided. A humidity sensor measures the moisture content within a cooking cavity. An output of the sensor is provided to a digital filter (20) to remove noise therefrom before being passed to a feature extraction means (21) which performs a data compression step and extracts salient features relating to the shape of the humidity versus time characteristic. The parameters are analysed by a neural network (22) to estimate a degree of doneness of the food. A controller (24) uses the degree of doneness to estimate the remaining cooking time and appropriate power level. The cooking apparatus (2) then operates in an open loop mode for the remainder of the cooking time using the appropriate power level.

An active matrix liquid crystal display comprises a rectangular array of picture elements (1) driven by data and scan drivers (2, 3). Each picture element (4) comprises a liquid crystal display element (9) connected to the output of a unity gain buffer amplifier (11). The input of the amplifier is connected to a hold capacitor (5) and to series connected gate transistors (6a, 6b). The gates of the transistors (6a) are connected to a scan electrode (8) and the transistors are connected in series between a data electrode (7) and the input of the amplifier (11). The output of the amplifier (11) is connected to the connection between the transistors (6a, 6b).

A retention memory (7) retains 2D image data picked-up and output by camera portion (3) in association with corresponding thumbnail image data (60). The 2D image data retained in the retention memory (7) is converted to 3D image data formed of image data for left-eye (L) and for right-eye (R) for stereoscopic vision of the image as desired. A retention portion (5) creates thumbnail image data (60) with a shrunken image based on this 3D image data and stores the created thumbnail image data and the 3D image data in the retention memory (7) in association with each other. The thumbnail image data (60) is created, for example, by reducing the left-eye image data (L) and the right-eye image data (R) of the 3D image data to satisfy a thumbnail size. A listing of thumbnails based on the thumbnail image data (60) in retention memory (7) is displayed on a display portion (10) so that the retained image can be recognized at a glance.
