Patent number: 8681878Abstract: A basic pattern generating unit 81 generates a film grain basic pattern 86 in which the histogram of random noise is substantially the same as the film grain basic pattern information 53. The film grain basic pattern 86 is of (64×64) pixels and an area of (16×16) pixels is cut out and supplied to a multiplier 84. Strength information 88 is generated based on film grain strength information 54 produced on the encoding side and an average value 87 of a pixel value in the area of (16×16) pixels of decoded image information 42. The strength of basic pattern 86 is adjusted by this strength information 88. Film grain image 89 whose strength is adjusted is added to the area of (16×16) pixels of the decoded image information 42 by an adder 85 by the unit of pixel.Type: GrantFiled: December 16, 2011Date of Patent: March 25, 2014Assignee: Sony CorporationInventor: Jun Murayama

Patent number: 8611615Abstract: The present invention relates to an image processing apparatus and method, and a program that are capable of more appropriately evaluating the image-capture state of an image. A blur degree score calculation unit 23 through to a chroma score calculation unit 27 extract a feature quantity of a pre-specified feature from an input image, and calculate a feature-by-feature score indicating an evaluation for the input image on the basis of the feature. For example, the luminance score calculation unit 24 extracts, as a feature quantity, a luminance value from the input image, and calculates a luminance score indicating an evaluation based on the distribution of the luminance values in the subject portion of the input image. The overall score calculation unit 28 calculates an overall score indicating the evaluation of the image-capture state of the input image from each feature-by-feature score.Type: GrantFiled: May 31, 2010Date of Patent: December 17, 2013Assignee: Sony CorporationInventors: Masatoshi Yokokawa, Kazuki Aisaka, Jun Murayama

Patent number: 8577137Abstract: The present invention relates to an image processing apparatus and method, and a program that are capable of more easily identifying an area of a subject in an image. A luminance information extraction unit 21 through to a motion information extraction unit 25 extract predetermined information from an input image and create an information map indicating feature quantities of features possessed by an area of a subject of the input image. Furthermore, the luminance information extraction unit 21 through to the motion information extraction unit 25 subtract an average value of the pixel values of the pixels of the entire information map from the pixel value of each pixel of the created information map so as to normalize the information map. As a result, the information map can be normalized, and noise can be removed with a simple process when compared to a case in which the information map is normalized using a DOG filter.Type: GrantFiled: April 30, 2010Date of Patent: November 5, 2013Assignee: Sony CorporationInventors: Kazuki Aisaka, Masaya Kinoshita, Takashi Kameya, Jun Murayama, Masatoshi Yokokawa

Patent number: 8494256Abstract: The present invention relates to an image processing apparatus and method, a learning apparatus and method, and a program which allow reliable evaluation of whether or not the subject appears sharp. A subject extraction unit 21 uses an input image to generate a subject map representing a region including the subject in the input image, and supplies the subject map to a determination unit 22. The determination unit 22 uses the input image and the subject map from the subject extraction unit 21 to determine the blur extent of the region of the subject on the input image, and calculates the score of the input image on the basis of the blur extent. This score is regarded as an index for evaluating the degree to which the subject appears sharp in the input image. The present invention can be applied to an image capture apparatus.Type: GrantFiled: August 26, 2009Date of Patent: July 23, 2013Assignee: Sony CorporationInventors: Kazuki Aisaka, Masatoshi Yokokawa, Jun Murayama
