  • Patent number: 8300956
    Abstract: A method compresses a digital continuous tone image of pixels situated on scan lines. The method includes the steps of, for a current pixel to be encoded, said current pixel having an actual pixel value, predicting a predicted pixel value based on pixel values of at least one previously processed pixel from the same image, using a fixed rule, determining a difference parameter based on a difference value of said predicted pixel value and the actual pixel value of said current pixel to be encoded, and inspecting the difference parameter for existence of an uninterrupted series of highest order bits having a value equal to zero, removing at least part of said highest order zero bits, and, if a number of bits within predetermined limits remains, generating a compression code having a predetermined fixed length, said code indicating the number of remaining bits.

  • Patent number: 8150156
    Abstract: A computer-implemented method for processing paper forms includes accepting a filled-in paper form conforming to a template at a computer system having a local memory, wherein the template is not stored in the local memory. Identification information is extracted from the filled-in paper form using the computer system. The identification information indicates a network address of a remote storage location external to the computer system, in which the template is stored. The template is retrieved responsively to the identification information by communication with the remote storage location via a wide area network (WAN). The filled-in paper form is processed responsively to the retrieved template.

  • Patent number: 8055072
    Abstract: The invention provides image display panels. The image display panel comprises a histogram generator, a tone slope generator, and an image transformer. The histogram generator receives an original image, counts the pixels of different gray levels to generate a histogram distribution of the original image, and compares the pixel counts at every gray level with a first threshold count to identify the peaks of the histogram distribution. The tone slope generator generates a tone slope based on the histogram distribution and peaks of the histogram distribution. The image transformer transforms the original image into a modified image based on the tone slope.

  • Patent number: 8055097
    Abstract: An image pick-up apparatus is disclosed which allows a reduction in degradation of images associated with a changed image magnification due to movements in a focus direction during image pick-up operation. The image pick-up apparatus has an image pick-up controller which performs a plurality of image pick-up operations for producing a single image and performs focus adjustment operation before each of the image pick-up operations to produce a first plurality of images, and an information producer which produces information on an image magnification of each of the first plurality of images. The image-pickup apparatus also has an image producer which produces a second plurality of images based on the first plurality of images and the information on the image magnification, and an image combiner which combines the second plurality of images to produce a single image.

  • Patent number: 8055076
    Abstract: A tag information production apparatus is disclosed which can apply tag information to a main image through a realistic amount of work. A time information acquisition section acquires time information of a main image selected on a working screen, and a key region setting section sets a key region at a position corresponding to a partial region in the main image specified arbitrarily by an operator. An identification information application section applies, to the set key region, region identification information which allows identification between the key region and a peripheral region. A key image production section produces a key image to which time information same as the time information of the main image is applied and in which the region identification information is applied to the key region set through the working screen.

  • Patent number: 8041131
    Abstract: A coding method, apparatus, and medium with software encoded thereon to implement a coding method. The coding method includes encoding cluster of consecutive non-zero-valued coefficients, the encoding of a cluster including jointly encoding joint events that each are defined by at least two parameters: the number of zero-valued coefficients preceding the cluster, and the number of non-zero-valued coefficients in the cluster. The encoding of the cluster also includes encoding a parameter indicative of the number of amplitude-1 trailing non-zero-valued coefficients in the cluster, in one version with the parameter indicative of the number of trailing amplitude-1 coefficients part of the joint events such that the coding is according to a 3-dimensional joint variable length coding table. The method further includes encoding the amplitudes of the non-zero-valued coefficients that are not encoded by the joint encoding, e.g., encoding the amplitudes of the other than the trailing amplitude-1 coefficients.

  • Patent number: 8041135
    Abstract: An apparatus and method encodes into block units an image in which halftone images and character and/or line images are mixed, and makes a substitution value, substituting for pixels in which pixels of a character and/or line image exist, a value whereby the occurrence of quantization errors of direct current components after frequency conversion is substantially zero, thereby minimizing block distortion of images when decoding. Therefore, a blocking unit inputs images in 8×8 pixel blocks. An acquisition unit acquires pixel data of character and/or line images as acquisition color information and acquires identification information identifying character and/or line image pixel positions. A substitution unit substitutes pixel data acquired as character and/or line images in image data of input blocks with a substitution value determined based on pixel data having halftone attributes.

  • Patent number: 8036471
    Abstract: A coding method, apparatus, and medium with software encoded thereon to implement a coding method. The coding method includes jointly encoding joint events that each are defined by a cluster of consecutive non-zero-valued coefficients, each joint event defined by three parameters: the number of zero-valued coefficients preceding the cluster, the number of non-zero-valued coefficients in the cluster, and an indication of which trailing coefficients up to a maximum number of M trailing coefficients have amplitude greater than 1, with the coding using a 3-dimensional joint VLC table. The method further includes encoding the amplitude of the non-zero-valued trailing coefficients that have amplitude greater than 1 encoding the amplitude of any remaining non-zero-valued coefficients in the clusters that have more than M non-zero-valued coefficients.

  • Patent number: 8023733
    Abstract: The grayscale of an input signal is converted without amplifying noise components thereof. A grayscale conversion portion performs grayscale conversion on an input signal IS to create a converted signal TS, a noise reduction degree determining portion determines a noise reduction degree NR that expresses a strength of noise reduction processing to be applied to the converted signal based on the input signal IS and the converted signal TS, and a noise reducing portion executes noise reduction processing on the converted signal TS based on the noise reduction degree NR. By doing this, it is possible to convert the grayscale of the input signal without enhancing the noise.
