A wall surface of the accommodating portion is positioned in a side where the sheet member is provided with respect to a rectilinear line connecting a rotation center of the image bearing member and a rotation center of the feeding member in a flat plane perpendicular to an axial direction of the image bearing member. The wall surface approaches the rectilinear line with an increasing level with respect to a vertical direction. The feeding member is provided vertically above a position where the cleaning member contacts the image bearing member. A rotational direction of the feeding member and a rotational direction of the image bearing member are the same.

  • Patent number: 10007846
    Abstract: An image processing method for a picture of a participant, photographed in an event, such as a marathon race, increases the accuracy of recognition of a race bib number by performing image processing on a detected race bib area, and associates the recognized race bib number with a person included in the picture. This image processing method detects a person from an input image, estimates an area in which a race bib exists based on a face position of the detected person, detects an area including a race bib number from the estimated area, performs image processing on the detected area to thereby perform character recognition of the race bib number from an image subjected to image processing, and associates the result of character recognition with the input image.

  • Patent number: 10009615
    Abstract: The present invention concerns a method of encoding an image, the image comprising a plurality of coding elements made of blocks of pixels, each block of pixels being encoded according to a coding mode out of a plurality of coding modes, the method comprising for each block of pixel to be encoded determining the coding mode to be used for the encoding of a given block of pixels by sequentially evaluating some coding modes in the plurality of coding modes; wherein the method comprises evaluating Inter coding modes and fast IBC coding modes; and no residue-test is conducted between the evaluation of the Inter coding mode and the evaluation of the fast IBC mode. Accordingly, some good predictors may be found more rapidly and the whole encoding process is speed up.
