  • Patent number: 9293491
    Abstract: A polarization image sensor includes: photodiodes arranged on an image capturing plane; a color mosaic filter in which color filters in multiple different colors are arranged to face the photodiodes; an optical low-pass filter which covers the color mosaic filter; and polarization optical elements located closer to a light source than the optical low-pass filter is. Each polarization optical element covers an associated one of the photodiodes and makes light which is polarized in a predetermined direction in a plane that is parallel to the image capturing plane incident onto the optical low-pass filter. The color filters are arranged so that light that has passed through polarization optical elements is transmitted through an associated one of the color filters in a single color. Each color filter covers multiple photodiodes.

    Abstract: In an embodiment, a solid-state image sensor comprises: pixels arranged in columns and rows; read signal lines each connected to pixels arranged in a row direction; and output signal lines each connected to pixels arranged in a column direction. The read signal lines are classified into a first type of read signal lines each connected to a group of pixels on which R and B rays are incident, and a second type of read signal lines each connected to a group of pixels on which G rays are incident. Two pixels (R, B) on two adjacent columns are arranged on two opposite sides with respect to the first type of read signal line. Two pixels (Gr, Gb) on two adjacent columns are arranged on two opposite sides with respect to the second type of read signal line.

  • Patent number: 8780213
    Abstract: In a learning process, first, images having different resolutions are obtained from a target region of the subject (S101). Further, the subject characteristic of the target region is obtained (S102). Then, the resolution conversion rules are learned from the images having different resolutions, and those are recorded to a storage device along with the subject characteristics (S103). When converting the resolutions, the resolution conversion rules learned for the corresponding subject characteristics are applied to each region of the original image so as to convert the resolutions of the original image.

  • Patent number: 8760529
    Abstract: In an embodiment, an image sensor includes pixels arranged in columns and rows, read signal lines connected to pixels arranged in the row direction. Each pixel is read in either a first exposure time or in a second exposure time shorter than the first exposure time. Each of a first type of read signal lines is connected to a group of pixels associated with the first exposure time, and each of a second type of read signal lines is connected to a group of pixels associated with the second exposure time. In two vertically adjacent horizontal pixel lines, the first type of read signal line is shared by two horizontally adjacent pixels associated with the first exposure time, and the second type of read signal line is shared by two horizontally adjacent pixels associated with the second exposure time.

  • Patent number: 8249370
    Abstract: A recording process records low-resolution video data while obtaining a high-resolution image in a window region being a portion of an entire image. Then, the process learns, as a resolution conversion rule, a resolution increasing parameter by using the high-resolution image. In a resolution increasing process, the resolution of the recorded low-resolution video data is increased by using the resolution increasing parameter learned in the recording process.

    Abstract: The solid-state image sensor of the present invention includes: multiple different types of pixel groups, which exhibit mutually different sensitivity properties that vary from one group to another according to wavelengths of incoming light, wherein each pixel has a photoelectric converter for outputting a pixel signal that changes with the intensity of the light received, and a reading circuit, which reads the pixel signal from each of the multiple types of pixel groups and which outputs an image signal representing an image that is associated with the type of a pixel group. The reading circuit outputs the image signal with the frame frequency changed according to the type of the pixel group.

  • Patent number: 7623174
    Abstract: For a first region being a portion of a storage section (202), a read-out pulse produced by a progressive scanning shift register (206) is used to perform a progressive read-out operation of reading out signals from all rows of image-storing pixels (221). For a second region including an entire region other than the first region, a read-out pulse produced by a skip scanning shift register (205) is used to perform a skip read-out operation of reading out signals from intermittently-selected rows of image-storing pixels (221). The progressive scanning shift register (206) produces the read-out pulse so that the first region moves every frame and an entire region of the storage section (202) is scanned over a plurality of frames.

  • Patent number: 7563635
    Abstract: In the present invention, an etching hole 21 is formed in a polysilicon film 14 as a cavity-wall member. Through the etching hole 21, hydrofluoric acid is injected, so as to dissolve a silicon oxide film 13, thereby forming a cavity 22. In the cavity 22, a detecting unit 12 of a sensor is in an exposed condition. Next, by sputtering, an Al film 16 is deposited in the etching hole 21 and on an upper face of a substrate. Thereafter, a portion of the Al film 16 positioned on the polysilicon film 14 is removed by etching back, thereby leaving only a metal closure 16a of Al which closes the etching hole. The sputtering step is performed under a pressure of 5 Pa or less, so that the pressure in the cavity can be held to be low.

  • Patent number: 7535486
    Abstract: The present invention provides a display control method and a display control device capable of detecting a position and an orientation of an apparatus by a simple structure and controlling a display of a displayed image based on the detected position and orientation of the apparatus with ease. Two cameras are mounted on the apparatus. A user holds the apparatus in the hand, captures, by a first camera, a first image including the face of the user, and captures, by a second camera, a second image including a scene opposite to the user. A display control unit extracts features of the face from the first image and extracts scene feature points from the second image. Then, the display control unit compares the extracted results with reference graphics and the like, and calculates a user-to-apparatus distance ro and angles ?o, ?o which indicate a direction to the apparatus, and controls the display of the displayed image based on the calculated distance ro and angles ?o, ?o.

  • Patent number: 7352910
    Abstract: An interpolated image obtained by enlarging and interpolating an image (IN) is subjected to predetermined vector transformation to calculate an image feature vector. Also, a characteristic of a subject is obtained to calculate a physical characteristic parameter of the interpolated image. The physical characteristic parameter is used to transform the image feature vector to sharpen the interpolated image. The transformed image feature vector is subjected to transformation inverse to the predetermined vector transformation to generate an enlarged image (ELI).

  • Patent number: 7340098
    Abstract: An image feature analyzing section performs an image feature analysis with respect to an input image to output an image feature vector. A parameter output section stores a plurality of image feature vectors and a plurality of parameters corresponding to the respective image feature vectors and outputs an original parameter value corresponding to an image feature vector. A parameter operation setting section determines contents of an operation of an illumination equation parameter, depending on a prescribed image conversion. A parameter operating section operates the original parameter value in accordance with a prescription of the parameter operation setting section, to obtain a new parameter value. An image generating section generates an output image based on the new parameter value.
