Abstract: In a method or device for interpolation and correction of a digital image, the source image is mapped to a target image with a FIR filter that comprises a plurality of filter coefficients, the filter coefficients comprising both information for interpolation and information for correction of the image. Both the interpolation and the correction of the image are executed in a single step.

Abstract: In a method or system for scanning a source image, the source image is scanned with a sensor that comprises multiple line arrays designed to detect a specific color such that a color separation of the source image to be scanned is generated by each line array. The color separations represent the source image in the form of pixels. The pixels of the different separations of the source image are at least partially offset relative to one another. The pixels of the color separations are separately filtered with multiple FIR sub-filters. The filtered pixels of the source image of the multiple color separations are summed into pixels of a target image.

Abstract: In a method for monitoring of a print image, a real image is electro-optically detected and digitized in individual pixels. A reference image is provided that is segmented into a plurality of segments such that respective pixels in the respective segments exhibit approximately a same color property as the respective segments, a reference value describing said color property being associated with the pixels arranged in the respective segments. Color properties of the pixels of the real image are compared with the corresponding reference values of the reference image, and given a deviation from a predetermined threshold value, a corresponding pixel is marked as an error in a result image.

Abstract: In a method for processing image data, at least one section of a form (10) is raster scanned and converted into a digital image with image points (22, 24, 26), the color of each image point (22, 24, 26) being represented as tone H, saturation S, and brightness B. Using fuzzy technology, the membership of the image points (22, 24, 26) ant their colors in color categories (UB, SF, BF) is determined by way of membership functions and a gray value GW is allocated to each image point (22, 24, 26) depending on the thus determined color category (UB, SF, BF).

Abstract: A method and apparatus for correcting a scanned image of a non-planar original that has a constant cross section in one direction, such as a book, provides for applying a coordinate system to the scanned image to align the coordinate system to the direction with the constant cross section. The scanned image is imaged onto a target image, or vise versa, using aspect factors or dilation factors. A single calculation is possible to map an image point from the scanned image to the target image and thereby remove the distortion of the non-planar original.

Abstract: The invention relates to a method and a device for the transformation of an image represented by grey tone values and/or colour valence values in a first co-ordinate system into a second co-ordinate system. According to this method, a relationship is created between the co-ordinates of source image pixels in an initial image and the co-ordinates of target image pixels in a target image, using a transformation matrix, in which co-ordinates of the target image pixels belonging to the natural value range can correspond with co-ordinates of the source image pixels which fall within the real value range and vice versa. Adjacent pixels are then taken into account in the determination of the valence values of a target image pixel, in which auxiliary co-ordinates are determined from the co-ordinates of two respective sequential source image pixels, in such a way that two target image pixels can be calculated from this.

Abstract: A retractor for a vehicle safety belt is provided, comprising a housing, a load bearing ratchet pawl supported in the housing, and a belt drum rotatably mounted in the housing. The belt drum is provided with ratchet disks at its axial ends. The ratchet disks are coaxial with the belt drum and are provided with a ratchet toothing at its outer circumference, into which the ratchet pawl can be engaged for locking the belt drum in the direction of pay-off of belt webbing coiled on the belt drum. The belt drum is further provided with energy take-up means arranged in the power transmission path between the belt drum and the ratchet disks. This energy take-up means are adapted to allow rotation of the belt drum in relation to the ratchet disks in the pay-off direction under heavy strain.

Abstract: A belt retractor is provided which comprises a housing, a belt drum mounted in the housing so as to be rotatable about an axis of rotation, and a spring drive for the belt drum. The spring drive comprises an output drive part connected with the belt drum in such a manner as to prevent relative rotation, an intermediate part arranged rotatably in relation to the belt drum and to the housing and being centered on the axis of rotation of the belt drum, a wind-up spring effective between the housing and the intermediate part, an auxiliary spring effective between the intermediate part and the output drive part, and a spring cover. The spring cover and the output drive part are provided with receiving means coaxial to the belt drum and having interlocking means for a pin. The pin is simultaneously engageable with both of the receiving means in such a manner as to prevent relative rotation. The intermediate part is rotatably mounted on the pin.

Abstract: A safety belt retractor is provided with a belt pretensioner device acting via a clamping roller coupling mechanism. A torsion rod (30) is arranged in the force flow path between the coupling mechanism and the belt drum (12) of the retractor, so that after tightening of the belt such torsion rod is twisted about its axis under the load transmitted by the belt with the consumption of energy. Owing to the plasitic deformation of the torsion rod (30), it is possible for the load peaks occurring following tightening of the belt in the belt system to be absorbed in order to increase the efficiency of the safety belt system.
