摘要： An attribute detecting apparatus of data signals obtains a block to which a mapped point belongs, for data signals divided into a plurality of blocks; sequentially repeats mapping processing in such a way that the mapped point belonging to the block is mapped to a similar region in the data signals previously allowed to correspond to the block (by setting an attribute detection position to an initial position of the mapped point and using the preceding mapping point as a new mapped point); and decides the attribute at the attribute detection position on the basis of position data of the mapping points obtained by the repeated mappings. An attribute detecting apparatus suitable for detecting the attributes of the fractal coded video signals can be realized.

摘要： A binary information display apparatus displays braille information with high accuracy by means of four braille pins, which are actuated by a stepping motor having a stepping angle of 45.degree. and, hence, eight step positions. The apparatus includes four pins; a triplet cam which acts on ends of three pins out of the four pins so as to independently urge such three pins to selectively project from a display surface of a pin-supporting member and to selectively retract the same behind the display surface; a stepping motor for rotating the triplet cam about an axis thereof; and a fourth cam portion which actuates the remainder of the four pins. The motor can perform consecutive seven steps at 45.degree. intervals, starting from a position where a rotation restricting projection on the fourth cam portion abuts a stopper step surface on the pin-supporting member, without causing rotation of the fourth cam portion. The state of the fourth pin is therefore not changed during such consecutive stepping of the stepping motor over seven steps. With the above-described structural arrangements and resulting operations thereof, it is possible to display eight types of braille information. Similarly, eight types of braille information can be displayed by reversing the motor. Consequently, sixteen types of braille information can be produced by the apparatus of this invention.

摘要： A detecting unit detects an object in an input image. A depth map generating unit selects a depth template corresponding to a type of the object and places a selected depth template on a depth map in accordance with a position of the object to generate the depth map having a depth value for each pixel. A correcting unit calculates a weight of at least one interested pixel and a weight of a peripheral pixel based on a relationship between pixel values to the interested pixel and the peripheral pixel and corrects the depth value of the interested pixel based on a weighted sum of the respective depth values corresponding to the interested pixel and the peripheral pixel. An image generating unit generates parallax images based on the corrected depth map and the input image.

摘要： An image processing device includes an estimator, a first calculator, a selector, a determination module, and a third calculator. The estimator estimates a motion vector to reference images of an input video from a target pixel of a process target image. The first calculator calculates candidate pixel values corresponding to positions in the reference images. The selector selects a motion vector for which the error is small as many as the number smaller than the number of motion vectors acquired for the target pixel. The determination module determines the candidate pixel values corresponding to the selected motion vectors. The third calculator calculates a pixel value after correction of the target pixel from an arithmetic average or a weighted sum of the candidate pixel value determined equal to or less than the reference and the pixel value of the target pixel.
