Abstract:
PROBLEM TO BE SOLVED: To provide an imaging device that can accurately and efficiently obtain light beam information at a desired point of view. SOLUTION: The imaging device 1 includes an imaging lens 11, a microlens array 12, an imaging element 13, an image processing unit 14, an imaging element driving unit 15, and a control unit 16. In the microlens array 12, a 3×3 pixel region 13A is assigned to each microlens 12M, with a lateral displacement d1 (=0.5Pw) being formed between the pixel region 13A and the microlens 12M. When obtaining light beam information at two points of view of left and right, influence by the edges of the microlenses can be avoided and only the necessary pixel data corresponding to, for example, the two points of view of left and right, can be selectively read out.

PROBLEM TO BE SOLVED: To provide an image pickup apparatus capable of changing the number of unit images formed on a microlens basis, in image pickup data obtained to include information in the traveling direction of a light beam. SOLUTION: This image pickup apparatus 1 includes: an image pickup lens 11; an image pickup element 13 held in the traveling direction of a light beam for obtaining image pickup data DO; a microlens array 12 with one microlens allocated to a plurality of pixels of the image pickup element 13; and an image processing part 14. The image pickup data DO include unit images U1 formed on a microlens basis. In the image processing part 14, a plurality of parallax images are generated based on the image pickup data DO by a parallax image generation part 143, and thereafter resize processing is applied to the plurality of parallax images by a resize processing part 144. In a rearrangement processing part 145, rearrangement processing is executed based on the image after the resize processing, and thereby image data having the number of unit images U1 different from that of the image pickup data DO are obtained.

PROBLEM TO BE SOLVED: To provide an optical pickup capable of reliably deciding the number of layers of an optical disk and to provide an optical disk device. SOLUTION: The optical pickup includes: a polarization optical element 18 having respective boundary surfaces at front and rear parts separated by a prescribed distance from a focused point on which focused light reflected by a focused recording layer in reflection light beams is condensed by a condenser lens 17 on the surface including optical axes of the reflection light beams condensed by the condenser lens 17 and changing the polarization direction of stray light contained in the reflection light beams by reflecting only the stray light reflected by a non-focused recording layer in the reflection light beams; a separating means 20 in which a reflection light beam emitted from the polarization optical element 18 is made incident and which separates focused light and stray light contained in the reflection light beam on the basis of its polarization direction; and a stray light detecting means 25 having a plurality of light receiving regions for detecting the light quantity of the stray light separated by the separating means 20.

Abstract:
PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of inserting an optional two-dimensional image in an optional depth direction in a stereoscopic image. SOLUTION: An image processing section 14 calculates a refocus coefficient α1 of a refocus plane which is a specified depth plane in a picked-up image corresponding to picked-up data acquired in a state where a traveling direction of a light beam is held. Further, the calculated refocus coefficient α1 is used to perform first rearrangement processing with respect to the picked-up data D1. Then composite image data D4 is generated through image composition processing for inserting predetermined two-dimensional image data (insert image data D3) into the picked-up data D2 after the first rearrangement processing. Consequently, insertion processing (the image composition processing) for the insert image data D3 is performed using the refocus coefficient α1 of the refocus plane which is the specified depth plane in the picked-up image.

Abstract:
PROBLEM TO BE SOLVED: To provide a biometrics authentication system having a small and simple configuration and implementing both of biometrics authentication and position detection. SOLUTION: The biometrics authentication system 1 includes a near-infrared light source 10, a cover glass 11, a microlens array 12, a light-receiving element 13, an image processing section 14, an authentication section 15, a position detection section 16, a light source driving section 181, a light-receiving element driving section 182 and a control section 19. When a living body 2 on the upper part of the cover glass is irradiated with light from the near-infrared light source 10, the light with which the living body 2 is irradiated is condensed by the microlens array 12, and then is sensed by the light-receiving element 13. Consequently, light-sensing data of the living body 2 is obtained. The image processing section 14 generates disparity image data, on the basis of the light-sensing data. The authentication section 15 performs biometrics authentication, on the basis of the disparity image data. The position detection section 16 performs position detection. The biometrics authentication and the position detection are performed by the same light source and detection optical system. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an input/output device displaying a high-resolution two-dimensional image and detecting a position of an object in a three-dimensional space though the input/output device is thin in thickness. SOLUTION: An input/output panel 10 of the input/output device 1 is installed with a lens substrate 12 having flat parts 12a and microlens parts 12b at a display face side of a display part 11. The display part 11 is mixedly disposed with display areas 11A and imaging areas 11B. Among them, the display area 11A is disposed opposite to the flat part 12a of the lens substrate 12, and the imaging area 11B is disposed opposite to the microlens part 12b of the lens substrate 12. An image displayed in the display area 11A is transmitted through the flat part 12a of the lens substrate 12 as image light. In the imaging area 11B, while information in an advance direction of light rays is held, imaging data D1 of a finger 100 are acquired. Based on the imaging data D1, a position (x, y, z) of the finger 100 is detected, and outputted as position data Dout. COPYRIGHT: (C)2010,JPO&INPIT
