    Abstract: An image processing apparatus is provided which performs image processing of an input frame image. Contrast analyzer generates a histogram of the input frame image and calculates contrast based on the histogram. Motion-detecting threshold setter calculates a lower-limit threshold and an upper-limit threshold of a motion-detecting threshold by using an input-operated motion-detecting level and the calculated contrast. Motion detector determines that an observation pixel is moving considerably in a case where a finite difference value between frames is greater than the upper-limit threshold, and sets composite ratio K such that compositing of a preceding frame image is not performed. In a case where the finite difference value is smaller than the lower-limit threshold, the observation pixel is determined to be stationary, and composite ratio K is set such that compositing of the preceding frame image is performed at the maximum ratio.

  • Patent number: 9967490
    Abstract: The invention relates to time delay integration (TDI) image sensors. The sensor includes means for detecting a shift of the sensor with respect to the image. The pixel matrix is divided in the column direction into at least a first and a second sub-matrix (Ma, Mb). On each side of each sub-matrix are arranged groups of additional columns (GRa1, GRb1, GRa2, GRb2). The shifts (Db2?Da2, Db3?Da3, etc.) in relative position of these groups between the first and the second sub-matrices are different from each other and make it possible to detect a relative shift of the sensor during travel. More precisely, the signals originating from groups of columns of same rank associated with the two sub-matrices are compared. The pair of groups that delivers the pair of signals that are closest to each other defines the probable shift of the sensor with respect to the image: this shift is equal to the relative position difference of these two groups.

    Abstract: An image-reading device reads an image of a sheet while conveying the sheet. The image-reading device sets target lines in the image for searching an edge pixel representing a sheet edge in the image. The target lines include first and second lines that are sequentially arranged. When the first target line includes an edge pixel, a mask region is set on the image. A detection unit searches an edge pixel by sequentially referring to the target lines except the first line according to a line order from the second line and detects a positional coordinate of the edge pixel from among pixels outside the mask. Once the edge pixel is included in the first target line, the mask region is set continuously and dynamically from the first target line to a target line on which detection of the edge pixel ends.

  • Patent number: 8988743
    Abstract: According to one embodiment, a document detecting apparatus includes a light-emitting element, a photoelectric conversion element, a light-emission controller and a detection processor. The light-emitting element projects light onto a detection position of a document. The light-emitting element is not used for reading an image of the document. The photoelectric conversion element converts light projected onto the detection position into an electric signal and outputs the electric signal. The light-emission controller changes the light quantity of the light emitted by the light-emitting element during a predetermined interval. The detection processor detects the presence or absence of the document at the detection position of the document based on whether a value of the output electric signal during the predetermined interval changes in correspondence to the change of the light quantity caused by the light-emission controller.

  • Patent number: 8970920
    Abstract: The apparatus of the present invention totalizes a frequency distribution while switching frequency distributions as targets, for each region having a set width, by using a sensor which captures document image data and a setting unit which sets a region width in accordance with frequency distribution generation targets. Upon detecting the trailing end of the document, the apparatus decides a remainder region which is not a totalization target in accordance with the remaining amount of image data of the document, and does not totalize any frequency distribution in the remainder region.

  • Patent number: 8947690
    Abstract: An image reading apparatus includes a carriage, a carriage detector, and a control unit. The carriage detector outputs a detection signal of the carriage when the carriage is at the home position, and outputs a non-detection signal of the carriage when the carriage is located closer to a document size reading position than a predetermined position between the home position and the document size reading position. The control unit moves the carriage to the home position when the image reading apparatus enters a sleep mode, keeps the carriage detained while performing initialization after the sleep mode is cancelled, and moves the carriage, upon receipt of a scanning instruction after the initialization is completed, toward the document size reading position in the case where the carriage detector outputs the detection signal of the carriage.
