Abstract: PURPOSE: To realize a high density reproduction, to reduce the spherical aberration occurring on a signal recording surface of an optical recording medium and to enhance the reproducing characterstics. CONSTITUTION: A semispherical lens 7 is provided with a plane 7b confronted with a light incident surface 20a of an optical disk 20, and is a convex lens, a refractive index of which is set in a prescribed value. A converging optical system 23 converges reflected light from the light incident surface 20a and the plane 7b. A PD 15 detects the reflected light R2 from the plane 7b through the converging optical system 23. A PD 19 detects the reflected light from the plane 76 through the converging optical system 23. A subtracter 21 detects a positional relation between the light incident surface 20a and the plane 7b based on the detection output Pb of the PD 15 and the detection output Pc the PD 19. An actuator 31 for the semispherical lens drives the semispherical lens 7 in the direction of the optical disk 20 or an objective lens 6 so as to control the gap of an air layer AG between the light incident surface 20a and the plane 7b based on the output Pb -Pc of the substracter 21.

Abstract: PURPOSE:To execute high density recording without deteriorating a signal to the limit of the resolving power of film by providing a digital sound track where digital sound data is optically two-dimensionally recorded as the data which does not include an isolated pit. CONSTITUTION:The digital sound data in 8-bit units obtained by digitizing an analog sound signal is two-dimensionally recorded on the digital sound track 5(6) as the pit pattern of 4X3=12 bits which does not include the isolated pit by 8-12 modulation. The shortest repeat lengthwise or breadthwise is equal to or above 2 pits, and the digital sound data is two-dimensionally recorded on the track 5(6) of motion picture film 1 as the pit pattern whose lengthwise and breadthwise four directions are not surrounded by other kinds of pits, so that any of up, down, right and left pits becomes the same kind. Therefore, the film 1 is hardly deteriorated by diffraction at the time of recording and the diffusion of particles at the time of developing.

Abstract: PROBLEM TO BE SOLVED: To provide an imaging device capable of obtaining a natural parallax image with few restrictions by polarized light.
SOLUTION: In the imaging device 1, by switching transmitting and blocking between two regions 12L, 12R in a liquid crystal shutter 12 by the driving of a liquid crystal shutter drive unit 14, image data are captured by an imaging element 13 based on the light rays received in each of the regions 12L, 12R. The light rays transmitted by the regions 12L, 12R, respectively, have a mutual parallax because the regions 12L, 12R are mutually different regions. These regions 12L, 12R are divided into sub-regions 12L1, 12L2 for selectively transmitting first polarized light and sub-regions 12R1, 12R2 for selectively transmitting second polarized light, respectively. The light rays received by each of the regions 12L, 12R in the imaging element 13 are based on both the first polarized light and the second polarized light.

Abstract: PROBLEM TO BE SOLVED: To provide an image pickup apparatus which can measure a distance to a measuring object and generate a two-dimensional image with a higher resolution than in the case where a microlens is provided over a surface. SOLUTION: The image pickup apparatus 1 includes an image pickup lens 11, a lens substrate 12, an image pickup device 13, an image processing section 14, an image pickup device driving section 15, and a control section 16. The lens substrate 12 has a microlens 12A provided on only a part of the substrate. In the image processing section 14, a distance information extracting section 143 extracts a distance from the image pickup lens 11 to the measuring object based on pixel data 13D of a microlens corresponding region 13M out of imaging data. In a pixel interpolating section 144, pixel interpolation is performed on the microlens corresponding region 13M, so that a two-dimensional image is generated with the same number of pixels as on the image pickup device 13.

Abstract: PROBLEM TO BE SOLVED: To provide a biometric authentication apparatus can achieve biometric authentication on a high security level while holding a display image by an image display function. SOLUTION: Imaging data of a living body 7 is obtained by near-infrared light LIR of an invisible light area. Information inside the living body 7 can thereby be easily obtained, and vein authentication can be easily achieved. Further, display light (white light Lw) in a visible light area is not influenced when acquiring the imaging data. Light from the living body 7 is condensed on a light receiving element 112 by each liquid crystal microlens 113 in a microlens array 65. Resolution in the imaging data is thereby improved in comparison with conventional devices. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide an image pickup apparatus capable of applying proper interpolation processing especially in obtaining a color image by using image pickup data obtained so as to include information of a light traveling direction.
SOLUTION: A color filter 15 in which colors are arranged in a unit arrangement 15A is provided on a light-receiving surface of an image pickup element 13. Image pickup data D0 to be obtained with the image pickup element 13 are used as pixel data of a plurality of colors corresponding to the color arrangement of the color filter 15. In an image processing section 14, the pixel data of the same position are extracted and composited per pixel region corresponding to each microlens in the image pickup data D0, thereby generating a plurality of parallax component images, and color interpolation processing is executed for each of the parallax component images. Since the position of lights and information of the traveling direction thereof are the same between adjacent pixel data in an parallax component image, the information is interpolated while being correctly stored. Since the unit arrangement of colors are the same between the color filter 15 and the parallax component image, the color information of the image pickup data D0 can be prevented from being damaged.
