  • Patent number: 9877390
    Abstract: A multilayer substrate including a multilayer body formed by laminating a plurality of insulating layers including via holes in the insulating layer as an uppermost layer of the multilayer body so as to pass through the insulating layer, and via conductors formed by filling the via holes with a conductive paste. The via holes are formed through lower end positions, upper end positions, and intermediate positions between the lower end positions and the upper end positions such that a diameter enlargement degree toward the upper end positions from the intermediate positions is larger than a diameter enlargement degree toward the intermediate positions from the lower end positions. By forming the via holes as described above, when the via holes are filled with the conductive paste from openings at the small diameter side of the via holes, exudation of the conductive paste from openings at the large diameter side is prevented.

  • Patent number: 7750950
    Abstract: An image combined high sensitivity image and low sensitivity image is provided with well-adjusted white balance and broad dynamic range. The image is obtained by multiplying the combined data by total gain that depends on scene. A white balance is adjusted with gain value calculated from of high output image data. Lv value representing luminance is calculated and compared with a threshold to decide whether or not the high sensitivity image and the low sensitivity image should be combined. First gamma correction unit performs gamma-correction for the image signal derived from the high sensitivity signal with first gamma character, second gamma correction unit performs gamma-correction for the image signal derived from the low sensitivity signal with second gamma character that is different from the first gamma character, and addition unit combines the image signal from the first gamma correction unit and the image signal from the second gamma correction unit.

  • Patent number: 7630573
    Abstract: Noise reduction processing in accordance with frequency band is executed. To accomplish this, a image data dividing circuit divides image data into image data having frequencies in a low-frequency region, image data having frequencies in a low- to intermediate frequency region and image data having frequencies in a low- to high-frequency region. These items of image data thus divided on a frequency-band basis are input to respective ones of noise reduction circuits that have been set to respective ones of parameters suited to noise reduction of image data having frequencies in the low-, low- to intermediate and low- to high-frequency regions, respectively. The items of image data that have thus undergone noise reduction processing conforming to frequency band are input to an image data combining circuit. The latter combines the image data so as to obtain image data representing one frame of an image.

  • Patent number: 7586525
    Abstract: CCD-RAW data obtained by sensing the image of a subject is applied to a first noise reduction circuit via a offset correction circuit, a gain correction circuit, a linear matrix circuit and a gamma correction circuit. Uncorrelated noise is removed from the CCD-RAW data in the first noise reduction circuit. The CCD-RAW data is subjected to synchronization (color interpolation) in the synchronization processing circuit, and luminance data Y and color difference data C is generated by an RGB-YC conversion circuit. The generated luminance data Y and generated color difference data C is subjected to noise reduction processing on a per-frequency-component basis in the second noise reduction circuit. Suitable noise reduction processing conforming to the state of image data before and after synchronization processing is executed.

  • Publication number: 20090051781
    Abstract: A CCD including primary photosensitive pixels that have a narrower dynamic range and secondary photosensitive pixels that have a wider dynamic range is used to obtain first image information from the primary photosensitive pixels and second image information from the secondary photosensitive pixels at one exposure, then the first image information and the second image information are stored as two separate files having names associated with each other. A user can select through a predetermined user interface whether or not the second image information should be stored and a dynamic range for the second image information. The dynamic range information for the second image information is stored in the file of the first image information and/or the header of the file of the second image information.

  • Patent number: 7400355
    Abstract: A received light quantity detection device where high-sensitivity pixels and low-sensitivity pixels are formed is used for photometry. It is possible to perform measurement over the low range (for example, 0[EV] through 8[EV]with a single occasion of photometry. In the case that both the high-sensitivity pixels and the low-sensitivity pixels are saturated, it is possible to perform further measurement over the high range (for example, 8[EV] through 16[EV]) by narrowing the aperture or increasing the electronic shutter speed for retried photometry with a retried photometry. This reduces the time required to calculate a correct exposure value on image pickup apparatus such as a camera.

  • Patent number: RE41161
    Abstract: When a picture image recorded by a digital camera is reproduced, a high quality picture image is immediately reproduced without repetitive test prints for enhancing a picture quality or repetitive minor adjustments based on a confirmation via a monitor. Recording is carried out by a digital camera having a function of adding recording information representing a recording condition (a recording information adding unit) to digital image data obtained by the recording. A set-up processing unit in an image reproducing apparatus carries out image processing on the image data obtained by the recording for enhancing a picture quality using the recording information added to the image data, and the image reproducing apparatus reproduces the image data in the form of a print or a display on a monitor.
