Patent number: 9672605Abstract: To increase the processing speed when median processing in the time direction is performed on color images, pixel values of each channel (R, G and B values) are extracted from multiple temporally consecutive frame images; subsequently, identifiers (index numbers) corresponding to frame images from which the pixel values are extracted are assigned to the pixel values; subsequently, a sorting process is performed on a set of pixel values of one channel (G values) to obtain an identifier assigned to a median value thereof; subsequently, a pixel value to which an identifier identical with that assigned to the median value is assigned is selected as a median value of each channel; and subsequently, a median image is generated on the basis of the median value of each channel obtained for each pixel.Type: GrantFiled: September 26, 2013Date of Patent: June 6, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Yoshiyuki Matsuyama, Kenji Tabei

Publication number: 20120213452Abstract: An image processing apparatus 100 selects one of multiple low-resolution images as a reference image candidate and determines transformation matrices for aligning the other aligning low-resolution images; conducts coordinate-transforming the other low-resolution images with the transformation matrices and plotting the reference image candidate and the coordinate-transformed low-resolution images on to a mapping image to generate a reconfigured image for reference image selection; gives a higher evaluation value to the reference image candidate as the number of pixels of the reference image candidate and the other low-resolution images plotted on the mapping image is larger. This image processing apparatus can select a reference image appropriate for generating a high-quality, high-resolution image from among multiple low-resolution images.Type: ApplicationFiled: February 14, 2012Publication date: August 23, 2012Applicant: PANASONIC CORPORATIONInventors: Yoshiyuki Matsuyama, Kenji Tabei

Patent number: 6142374Abstract: An optical character reader is provided for detecting frame lines of a character entry frame printed on a medium in which a character is written. The optical character reader includes a scanner, a frame width determining circuit, and a frame line equation defining circuit. The scanner scans the medium to produce a bit-mapped image of the medium including a character entry frame image represented with black pixels. The frame width determining circuit determines a width of the frame lines of the character entry frame based on a histogram of the number of black pixels continuously arranged over one of the frame lines in a direction perpendicular to the length of the frame lines. The frame line equation defining circuit defines line equations representing side boundaries of each of the frame lines according to a least squares method using set of pixels arranged on sides of each of the frame lines over the width of the frame lines to determine locations of the frame lines on the bit-mapped images.Type: GrantFiled: January 20, 1998Date of Patent: November 7, 2000Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Yoshiyuki Matsuyama
