Patents by Inventor Masanori Harasawa

Masanori Harasawa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9735190
    Abstract: There is provided a solid-state imaging device which includes a plurality of pixels including an imaging pixel for generating a captured image and a focus detection pixel for detecting a focus, in which the focus detection pixel includes a microlens, a photoelectric conversion unit which receives light incident from the microlens, a light-shielding unit which shields a portion of light incident on the photoelectric conversion unit, and a dimming filter which dims the light incident on the photoelectric conversion unit and is formed to contain a black pigment. The present technology can be applied to, for example, a CMOS image sensor.
    Type: Grant

  • Patent number: 8779541
    Abstract: A solid-state imaging device including a plurality of pixels arranged two-dimensionally, wherein each of the pixels has at least a planarizing film formed on the upper side of a photoelectric conversion element, a filter formed on the upper side of the planarizing film, and a microlens formed on the upper side of the filter. The filter of some of the pixels is a color filter permitting transmission therethrough of light of a predetermined color component, whereas the filter of other pixels is a white filter permitting transmission therethrough of light in the whole visible spectral range. The refractive indices of the white filter, the microlens and the planarizing film have the following relationship: (Refractive index of white filter)?(Refractive index of microlens)>(Refractive index of planarizing film).

  • Publication number: 20070287087
    Abstract: The present invention provides a colored photosensitive resin composition which causes a small change in exposure when a pattern is subjected to projection exposure. Disclosed is a colored photosensitive resin composition comprising a dye, a photo acid generator, a curing agent, an alkali-soluble resin, a solvent, and a compound represented by the formula (I): in the formula (I), R1 to R3 each independently represents a hydrogen atom, a linear alkyl group having 1 to 6 carbon atoms, a branched alkyl group having 3 to 12 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms or an aryl group having 6 to 12 carbon atoms, and a hydrogen atom on the linear alkyl group having 1 to 6 carbon atoms, a hydrogen atom on the branched alkyl group having 3 to 12 carbon atoms, a hydrogen atom on the cycloalkyl group and a hydrogen atom on the aryl group may be substituted with a hydroxyl group, provided that at least one of R1 to R3 represents a group other than a hydrogen atom.
