Abstract: A deformable mirror device compensates the spherical aberration caused by the difference of thickness of the cover layers covering recording layers of an optical disc. Circular projections are concentrically arranged on a flexible member (2) where a mirror surface (3) is formed to produce a strength distribution pattern (2a). Attractive force is generated as electrostatic force between an upper electrode (8) and a lower electrode (9) according to the voltage applied from a drive circuit (10) so as to contract the second space (7) and accordingly expand the first space (5) in order to deform the mirror surface. At this time, the profile of the mirror surface is deformed to show a desired profile that can compensate the spherical aberration by the pattern formed on the flexible member (2) as strength distribution pattern (2a). With this arrangement, only a single drive actuator (10) is needed to deform the mirror surface to simplify the configuration and the control operation.

Abstract: A focus control apparatus conducts a focus control with respect to an imaging apparatus configured to vary the focal point using a deformable mirror. An imaging unit first obtains image data via imaging elements and imaging optics provided in the imaging apparatus. A controller controls the driving of the deformable mirror such that, during a first image reading period wherein the reading of an image signal is periodically executed by means of the imaging elements, a focus drive state is achieved whereby an in-focus point that has been found in advance is set as the current focal point. During a second image reading period different from the first image reading period, the deformable mirror is controlled so as to achieve a focus drive state for in-focus point search.

Abstract: When a two-dimensional display section including a plurality of pixels of p colors and a lenticular lens slanted with respect to a pixel array are combined to emit a plurality of light rays corresponding to a plurality of viewing angles into space by surface segmentation at the same time. Moreover, relative positional relationship between each cylindrical lens and each pixel of the two-dimensional display section is periodically changed to periodically displace the emission direction of display image light from each pixel via each cylindrical lens. Images corresponding to a unit frame of a three-dimensional image are time-divisionally displayed on the two-dimensional section, and a timing of time-divisional display in the two-dimensional display section 1 and a timing for changing relative positional relationship are synchronously controlled. Thereby, stereoscopic display with higher definition using a combination of a surface segmentation system and a time-division system is performed.

Abstract: In the three-dimensional display, a two-dimensional display section generates a two-dimensional display image based on an image signal, and a lens array converts the wavefront of the display image light from the two-dimensional display section into a wavefront having a curvature which allows the display image light to focus upon a focal point where an optical path length from an observation point to the focal point is equal to an optical path length from the observation point to a virtual object point, so a viewer can obtain information about an appropriate focal length in addition to information about binocular parallax and a convergence angle. Therefore, consistency between the information about binocular parallax and a convergence angle and the information about an appropriate focal length can be ensured, and a desired stereoscopic image can be perceived without physiological discomfort.

In addition, the shielding means is formed from an absorptive or reflective film placed in a region outside the prescribed optical path or through machining the region outside the prescribed optical path.

Abstract: Disclosed are an optical disk recording and reproducing apparatus, a remote controller, and a content management method capable of allowing a user to easily confirm contents recorded on an optical disk, wherein an optical disk is integrally provided with a read-only RFID tag that records only a disk ID to identify the optical disk as an individual. When a content is recorded on the optical disk, a video recorder records disk management information including the disk ID of the optical disk and index information about the content. After the content is recorded, a remote controller noncontactly reads the disk ID from the RFID tag of the optical disk and transmits the disk ID to the video recorder. The video recorder extracts index information corresponding to the received disk ID from the disk management information and displays the index information in a list.

Abstract: An evaporator is constructed such that bundles of heat exchanger tubes for flowing cold water are disposed inside a container for admitting the cooling medium. When a total cross sectional area of the heat exchanger tubes at various locations in a flow passage of the cold water is compared, the total area in a downstream location is less than a total area in an upstream location of the flow passage. Therefore, even though the temperature differential between the cold water and the cooling medium is small, the flow speeds of the cold water in the downstream tubes become faster than that in the upstream tubes, so that the heat flux is increased and heat transfer rate is improved.
