PROBLEM TO BE SOLVED: To provide an optical pickup wherein deformation of a liquid crystal element for phase modulation due to environmental temperature change is suppressed as much as possible and desired phase distribution can be given to transmission light transmitted by the liquid crystal element. SOLUTION: A phase modulation apparatus 30 used for the optical pickup has a pair of substrates 40 and 50 (50 and 60), a first seal 31 (a second seal 32) bonding these substrates, a first liquid crystal 34A (a second liquid crystal 34B) held between the pair of substrates and a porous material 80 as a pressure relaxing member relaxing displacement of the substrates 30, 40, and 50 caused by volume change of the first liquid crystal 34A (the second liquid crystal 34B) due to environmental temperature change and provided in contact with a first liquid crystal injection port 37a (a second liquid crystal injection port 37b). Displacement of the substrates caused by volume change of the liquid crystal due to environmental temperature change can be relaxed and the phase modulation apparatus 30 can always form fixed desired phase distribution without being affected by environmental temperature change by providing the pressure relaxing member.

PROBLEM TO BE SOLVED: To provide an optical pickup and a phase modulation apparatus in which defect of a converged spot caused by existence of an injection opening of liquid crystal of a liquid crystal element for phase modulation can be suppressed to the minimum. SOLUTION: In a first liquid crystal element 30A for phase modulation, first power feeding wires 51 and 52 connected electrically to a first electrode 58 are positioned in a region in which a first liquid crystal injection opening 32a of a first seal 32A sticking a pair of substrates 40 and 50 and the first electrode 58 are connected. Thereby, in light transmitting through the first liquid crystal element 30A, a defective position caused by the first power feeding wires 51 and 52 and a defective position caused by the first liquid crystal injection opening 32a caused by variation of environment temperature or the like are almost overlapped, less defect light can be obtained.

PROBLEM TO BE SOLVED: To provide an image processing device, an image processing method and an image processing program which are able to reduce the amount of data.SOLUTION: The image processing device includes a calculation part and a correction part. The calculation part calculates depth, in an optical axis direction in a sample, of a bright point to be obtained by coloring a target included in an observation region, on the basis of a first blur image and a second blur image. The first blur image is an image of at least a part of the observation region of the sample, obtained by relatively moving an objective lens of a microscope and the sample along the optical axis direction of the objective lens. The second blur image is an image of the observation region, obtained by relatively moving the objective lens and the sample along a direction which contains a component in the optical axis direction and is different from the optical axis direction. The correction part corrects the first blur image on the basis of the depth information of the calculated bright point.

Since area detection is applied to the second image captured under the ultraviolet irradiation in addition to the first image captured under the visual light irradiation, even an area having small contract under visual light can be detected as a specimen area.

PROBLEM TO BE SOLVED: To provide an image processor, an image processing method and an image processing program capable of accurately detecting a detection object from a background.SOLUTION: The image processor of the present invention comprises: an edge detection processing unit 12; a subdivision area setting unit 13; an edge constituent index value calculation unit 14; and a detection object determination unit 15. The edge detection processing unit 12 executes edge detection processing to a detection target image which includes an image of a detection object in part so as to generate an edge image. The subdivision area setting unit 13 divides the edge image into subdivision areas. The edge constituent index value calculation unit 14 calculates an edge constituent index value indicating an amount of edge constituents included in a subdivision area with respect to each subdivision area. The detection object determination unit 15 compares the edge constituent index value with a threshold value to determine existence of the detection object with respect to each subdivision area. This image processor binarizes luminance through executing an edge detection processing to a detection target image, thus enabling detection of even a detection object with smaller difference of luminance from a background.

PROBLEM TO BE SOLVED: To provide an information processor, an information processing method, a program, an imaging device and an imaging device having a light microscope which can generate multiple images subject to which stitching processing, while suppressing deterioration of an imaged sample.SOLUTION: In an observation area provided on an XYZ stage of a light microscope, first and second photographing areas 11 and 12 which are multiple in a Y axis direction are arranged so as to be overlapped with each other in an X axis direction. The first and second photographing areas 11 and 12 are arranged so that adjacent ones are overlapped with each other at first and second overlapping areas 20 and 40, and so that the first and second overlapping areas 20 and 40 do not overlap. Thus, cumulative quantity of excitation light redundantly radiated, at the first and second overlapping areas 20 and 40, can be decreased. As a result, the multiple first and second photographing areas 11 and 12 can be photographed and images thereof can be generated while suppressing deterioration of a sample 306.
