  • Patent number: 11308318
    Abstract: An image processing apparatus generates a first image by adjusting luminance so as to preserve a signal value on a high-luminance side among signal values acquired by reading a document by a scanner, and detects a position of a region corresponding to the document in the generated first image. The image processing apparatus further generates a second image by performing adjustment so as to increase luminance of a pixel contained in the first image, and crops a document image from the generated second image based on the detected position of the region corresponding to the document.

  • Patent number: 11069068
    Abstract: To make it possible to cut out an image area corresponding to a document with a high accuracy from an image obtained by scanning a document without forcing a user to perform complicated work or without giving a feeling of discomfort at the time of performing multi-crop processing. To this end, first, position information on the document is acquired by detecting an edge component from a first image obtained by setting high the first white reference value. Then, an image area corresponding to the document is cut out based on the acquired position information from a second image obtained by setting the second white reference value lower than the first white reference value.

  • Patent number: 10455117
    Abstract: A binary image of an input image is generated, and a character region within the binary image and a region surrounding each character are acquired as character segmentation rectangle information. A thinning process is executed on a region within the binary image which is identified based on the character segmentation rectangle information to acquire a thinned image. An edge detected image of the region identified based on the character segmentation rectangle information is acquired. Whether each character identified based on the character segmentation rectangle information is a character to be separated from a background by the binarization process or not is determined based on a result of a logical AND of the thinned image and the edge detected image.

  • Patent number: 10438376
    Abstract: An image processing method for processing an image includes determining, selecting, and replacing. It is determined whether a portion, including a plurality of pixels and darker than a threshold in the image, is subject to a color replacement. One predetermined color from among a plurality of predetermined colors is selected, based on a color of at least a part of the plurality of pixels. Based on the determination, a color of the portion is replaced with the selected one predetermined color.

  • Publication number: 20150146224
    Abstract: In a case where an image and another image are integrated into one file, brightness, dynamic ranges, etc., of the images are different from each other. Consequently, an image processing apparatus obtains first image information indicative of characteristics of a first image obtained from a first device and second image information indicative of characteristics of a second image obtained from a second device that is a device different from the first device. Then, the first image is corrected based on the first image information and the second image information. The first image that is corrected and the second image are combined.

  • Patent number: 8743419
    Abstract: Provided is an image processing apparatus and image processing method that make it possible to reduce jaggedness and blurring that may occur when performing resolution conversion of an inputted image from low resolution to high resolution, and make it possible to output a high-resolution image. When performing the conversion from low resolution to high resolution, a multi-gradation signal value pattern that surround a pixel of interest for which interpolation is being performed is acquired. By performing pattern matching, a pattern that corresponds to the acquired signal value pattern is extracted from among pattern files that are prepared in advance for the acquired signal value pattern, after which the image is converted to high resolution by signal value substitution and then outputted.
