摘要： An image decoding unit (801) decodes encoded image data and stores it temporarily. An image address bus (123) and an image data bus (124) connect the image decoding unit (801) with an image display section (901). The image display section (901) stores image data of a dynamic image or the like in a frame memory (914) that is an existing circuit and superposes the image of a specific area generated by the image decoding unit (801) on the image generated on the preceding time stored in the frame memory (914) to display these images. Thus, it is possible to alleviate the traffic of a bus of a MPU (microprocessor unit) and to rapidly draw a high-capacity image of the dynamic image or the like by a relatively easy addition of functions.

摘要： An image transmission device (100) uses a receiver (101) to receive a signal transmitted through a transmission line, demodulate and compress the signal, and convert it into coded data. The coded data from the receiver (101) is decoded in a decoder (102) of a video CODEC, and then converted by an image area converter (103) so that an erect image can be displayed at full size in a display area of the screen of a display (104). The image corresponding to the image data converted by the image area converter (103) is displayed on the display (104).

摘要： A decoding unit (111) decodes encoded data inputted to video data, and outputs the video data as occasion to a video data writing unit (112). Each time a predetermined amount (e.g., one frame) of video data is outputted, a decoding end notifying signal is outputted to a video data reading unit (114) and a control signal producing unit (115). The video data writing unit (112) writes the video data in a storage unit (113) as occasion. The video data reading unit (114) operates intermittently at timings at which the encoding end notifying signal is inputted, to read a predetermined amount of video data (201) from the storage unit (113). The control signal producing unit (115) produces a control signal (206) for designation a new portion in the video data decoded by the decoding means. In response to a decoding end notifying signal (204), the video data reading unit (114) outputs the control signal (206) synchronously with the timing at which the output from a video data outputting unit (116). Without any outside accessory circuit, therefore, the video data can be intermittently transferred from a decoding device (101) to a display device (121) thereby to reduce the size and lower the power consumption of a mobile terminal device for video communication and to lighten the processing load required to monitor an MPU.

摘要： Important quantized coefficients of which absolute values are higher than a threshold value are extracted from each of quantized coefficient streams into which a digital image signal is transformed, and an important quantized coefficient stream composed of the important quantized coefficients and zero-valued quantized coefficients is produced on condition that the number of important quantized coefficients and zero-valued quantized coefficients is equal to that of quantized coefficients in each quantized coefficient stream and positions of the important quantized coefficients in the important quantized coefficient stream are the same as those in a corresponding quantized coefficient stream. Also, a lesser-important quantized coefficient stream is produced by subtracting the important quantized coefficient stream from the corresponding quantized coefficient stream. High precision type error correction codes are added to each important quantized coefficient stream and are transmitted to a decoding apparatus, and low precision type error correction codes are added to each lesser-important quantized coefficient stream and are transmitted to the decoding apparatus. Therefore, an image having a superior quality can be reproduced with a high code efficiency.

摘要： A screen control means (106) determines a priority, a scaling factor and a picture synthesizing position. A picture selecting means (101) selects a picture from among a plurality of inputted pictures in accordance with the priority. Picture processing means (102) enlarges or reduces the selected picture in accordance with a scaling factor. A movement detecting means (103) detects the parts of the picture processed by the picture processing means (102) which show no movement. A frequency analyzing means (104) detects the parts of the picture processed by the picture processing means which have no features. An adaptive picture synthesizing means (105) synthesizes the enlarged or reduced picture at a picture synthesizing position indicated by the movement detecting means (103) and the frequency analyzing means (104). With this process, even if a display object picture is added in addition to an opponent picture and a self-picture, effective synthesized display can be obtained and, even if the resolution of a display device is changed, the change can be flexibly coped with, so that it can be avoided that the main picture part on a main screen is covered by a sub-screen.

摘要： A vertical area specifying circuit (141) outputs a vertical area specifying signal according to vertical display position information, the vertical synchronizing signal, and horizontal synchronizing signal to a vertical driver (103). A horizontal area specifying circuit (142) outputs a horizontal area specifying signal according to horizontal display position information, the pixel synchronizing signal, and the vertical and horizontal synchronizing signals to a horizontal driver (102). The horizontal driver (102) outputs the inputted video signal to a video display surface (101) through the signal line at the horizontal coordinate corresponding to the number of pixel synchronizing signals counted from the timing when the horizontal synchronizing signal is inputted while the horizontal area specifying signal is effective. The vertical driver (103) holds the number of synchronizations of the horizontal synchronizing signal while the vertical area specifying signal is effective and selects the signal line at the vertical coordinate corresponding to the number of synchronizations. Displayed on the video display surface (101) is the video signal outputted from the horizontal driver (102) in the position specified by the horizontal coordinate corresponding to the signal line through which the video signal is outputted and by the vertical coordinate corresponding to the signal line selected by the vertical driver (103).

摘要： A method for encoding and decoding digital moving picture signals which can decode subframes appropriately in relation to time if a part of a bit stream is missing or an error occurs in the bit stream, and can suppress degradation of a reproduced picture if decoding of a subframe including a picture in motion in relation to time becomes unfeasible. In the method for encoding and decoding digital moving picture signals of this invention, information for one frame is encoded correspondingly to a spatial hierarchy of a frame, subframes and blocks. A subframe time position number and a subframe space number are attached to an identifier of each of the subframe, thereby resuming appropriate decoding of the subframes immediately after a trouble if an error occurs. The subframe identifiers are placed at a certain interval in the bit stream so as to give a smaller size to a subframe including a block which is in motion and difficult to be encoded, thereby suppressing degradation of a reproduced picture if decoding of the subframe becomes unfeasible.

摘要： An input picture signal is divided into blocks. The blocks are grouped into groups each having a plurality of blocks. The input picture signal is encoded into a second picture signal block by block. The second picture signal uses a variable length code. An error correction signal is added to the second picture signal for each of the groups. A signal of a start address and a signal of a location address are added to the second picture signal for each of the groups. The start address represents a position of a bit within each of the groups. The location address representing a spatial position of a block within each of the groups.
