  • Publication number: 20130265615
    Abstract: An image processing apparatus of one aspect of this invention detects a specific pattern corresponding to a fine pattern in the input image data, and detects pixels corresponding to the specific pattern. Furthermore, the image processing apparatus specifies a pixel, which corresponds to the detected specific pattern, and a degree of juxtaposition color mixture of which does not exhibit a value within a predetermined appropriate range, and executes, for the input image data, image processing (blur processing) for adjusting the degree of juxtaposition color mixture, which represents a color mixture state when dots of respective colors formed using pixel values of respective colors included in the input image data are superposed on each other, of the specified pixel to fall within the predetermined appropriate range.

  • Publication number: 20130243251
    Abstract: An image processing device includes a memory unit, a candidate pupil detecting unit and a pupil determining unit. The memory unit is used in storing information regarding a pupil size. The candidate pupil detecting unit detects noncircular candidate pupils from an image in which an eye area is captured. The pupil determining unit extrapolates the shapes of the candidate pupils that are detected by the candidate pupil detecting unit and, based on the pupil size stored in the memory unit, determines a pupil from among the candidate pupils.

  • Patent number: 8335458
    Abstract: An image forming apparatus includes first and second drums subjected to image formation by exposure to light at exposure positions to form latent images and then transferring toner images, formed by developing the latent images with toner, onto a transfer material at transfer positions; first and second gears provided coaxially and integrally with the drums; a driving source for rotationally driving the drums; and a branch gear, meshable with the first and second gears at first and second mesh points, for transmitting a driving force from the driving source to the first and second gears. A sum of a time of movement of a portion of the branch gear located at the first mesh point to the second mesh point and a time of integer-time rotation of the branch gear is equal to a time of movement of the transfer material from the transfer position of the first drum to that of the second drum.

  • Publication number: 20120148315
    Abstract: An image forming apparatus of this invention transfers pattern images for color deviation detection of the respective colors for color deviation detection on an endless belt for the formation of images, and corrects color deviation occurring when each image forming unit forms an image on a recording material, in accordance with the amount of color deviation detected by a registration detection sensor. The image forming apparatus forms pattern images of the respective colors on the endless belt at the intervals determined based on the total variation obtained by totalizing each variation of the transfer and detection positions of a pattern image of each color on the endless belt from an ideal position. This enables to reduce color deviation detection errors by using pattern images for color deviation detection and improve the accuracy of color deviation correction.
