  • Publication number: 20070019882
    Abstract: A makeup simulation enables a high-quality simulation image quickly and simply. A first image generator portion 20 generates n transparency layer images in which the transparency of each pixel is normalized on the basis of n layer images in a use-reference image. A second image generator portion 30 generates n color converted layer images by applying a color conversion on a frame image using color components of the layer images. A mesh setting portion 50 sets a mesh in a facial region in each frame image and a makeup pattern image. An image deformer 60 calculates a difference between vertices of meshes in both images and deforms a makeup element image in each normalized transparency layer image based on this difference to fit in the facial region of the frame image. A synthesizer 70 synthesizes color converted layer images and each frame image by alpha blending.

  • Patent number: 5909537
    Abstract: There is provided a control method of a microfilm image reader, in which a scanner reads an image in a frame recorded on a microfilm and supplies image data of the read image to a printer, for printing out image data of an original image faithfully in a relatively easy processing even if the original image largely contains middle tone portions, without either calculating a threshold value for binarization by a complicated method or performing a special image processing to be uniquely performed to a binary density image. The scanner reads the image in a multi-tone gradation and the printer prints out image data of at least one portion of the read image in the multi-tone gradation. When the image in a frame contains both a multi-tone gradation portion in a photograph area and a binary density portion in a document area, image data of the photograph area and image data of the document area are printed out in the multi-tone gradation and the binary density or gradation, respectively.

  • Patent number: 5690406
    Abstract: A control method of a microfilm image reader is provided for reducing the amount of image data to be transferred from a scanner to a host computer, making the transfer time short and hence lengthening the free time of a bus, reducing the storage capacity needed for storing the image data, and simplifying the operation procedure by omitting the process of eliminating the black frame portion when printed out. The host computer supplies the scanner with a window parameter containing a range of reading area, and the scanner detects only an image area from all the reading area to transfer image data of the detected image area to the host computer together with attribute information containing the size of the image area. The attribute information may be managed by a header system, and data on a print position of the target image may be contained in the attribute information.
