Abstract: In a case where a balloon is broken and a body fluid reversely flows into a feed/discharge tube during a suction operation of a balloon control apparatus, a pump is stopped by operation-canceling section after passing of a preset predetermined time, and the suction operation of sucking the fluid into a bottle is canceled. Thereby, the amount of recovered liquid in the bottle is limited within a predetermined capacity. Thus, even in the case where the body fluid reversely flows into the feed/discharge tube, the body fluid does not overflow from the bottle, and the body liquid can properly recovered in the bottle.

Abstract: An ultrasonic transducer for producing an ultrasonic tomographic image is included in a distal part of an ultrasonic endoscope to be inserted into an object of observation. The ultrasonic transducer is rotated. Echoes of ultrasonic waves produced by the ultrasonic transducer are detected in order to produce an ultrasonic tomographic image that is a two-dimensional image. A magnetic sensor for detecting a position is included in the distal part. A magnetic field generated by a magnetic field generator locked near the object of observation is sensed. The position and orientation of the distal part are detected, whereby information of a position and orientation relevant to the ultrasonic tomographic image is obtained. Based on the information of the position and orientation, a plurality of produced ultrasonic tomographic images is synthesized in order to produce an ultrasonic image that is a three-dimensional image. The periphery of the magnetic sensor in the distal part is made of a non-conductive material.

Abstract: A reading section optically reads a code from a recording medium having a portion on which multimedia information including at least one of audio information, video information, and digital code data is recorded as an optically readable code. A plurality of processing sections sequentially process the code read by the reading section and output the processed code as the original multimedia information. An operation switch designates the start of reading of the code. A control section causes one or a plurality of the plurality of processing sections to terminate a processing operation for a code which has been read by the time the operation switch is operated, and executes processing for data of the processed code in correspondence with another processing section on a subsequent stage, on the basis of the operation of the operation switch after the start of reading is designated by the operation switch.

Abstract: A DCT circuit converts a specific block scanning signal into DCT coefficients. An encoder quantizes and Huffman-codes the image signal converted into DCT coefficients to compress it. A code memory stores the compressed image data obtained by quantizing and Huffman-coding a specific block scanning signal at the encoder. An IDCT circuit Huffman-decodes and inverse-quantizes the data read from the code memory and converts it into image data. An in-block horizontal scanning/in-block vertical scanning conversion circuit converts the image data into an in-block vertical scanning signal. An adaptive convolution filter effects the horizontal filtering of the in-block vertical scanning signal to remove the distortion of block boundary. An in-block vertical scanning/in-block horizontal scanning conversion circuit converts the image signal from which distortion has been removed into horizontal scanning direction. An adder circuit reconstructs and outputs the original image.

Abstract: A raster/block converting section converts an input raster image signal into a block scan signal. A compressing/coding section selectively compresses and codes one of the block scan signal, converted by the raster/block converting section, and a differential signal. An expanding/decoding section expands and decodes the block scan signal compressed and coded by the compressing/coding section. A block/raster converting section converts the block scan signal, expanded and decoded by the expanding/decoding section, into a raster signal. A filter section filters the raster signal, converted by the block/raster converting section, to remove deformation at a boundary between blocks. A differentiating section substantially obtains a difference between the raster signal filtered by the filter section and the input raster image signal and supplies the difference as the differential signal to the compressing/coding section.

Abstract: In an electronic still camera system for forming one still frame image by synthesizing odd and even field images which are field-sequentially output from a CCD, an image compensation circuit is arranged to prevent a deterioration in quality of a still frame image due to an image shift between the two field images. The image compensation circuit includes an interpolation circuit for obtaining two pseudo frame images by performing field interpolation of the odd and even field images, a correlation arithmetic circuit for detecting an amount of image shift between the two field images on the basis of the correlation between the two pseudo frame images, and a shift compensation circuit for compensating the image shift by shifting one of the two field images in accordance with the detected amount of image shift. The correlation arithmetic circuit divides each field image into a plurality of blocks, and detects an amount of image shift in units of blocks.

Abstract: During a recording operation, when receiving compressed moving-picture data from the moving-picture compression encoder, the code arrangement converter rearranges the data so that the core frame data may be distribution-recorded in a particular place on each track of the tape, for example, in the head portion of the main data area. In normal reproduction, the reproduced main data undergoes error correction and deinterleaving at the format reverse-converter. The resulting date is rearranged by the code arrangement reverse-converter to form the compressed moving-picture data in the same arrangement in recording. This compressed moving-picture data passes through the moving-picture expansion decoder and appears at the output terminal. During high-speed reproduction, for example, 9-fold speed reproduction, the main data in a frame corresponding to one of core frames 0 to 8 is reproduced. The resulting signal undergoes error correction and deinterleaving at the format reverse-converter.
