A tissue-sensing adaptive radar method of detecting tumours in breast tissue uses microwave backscattering to detect tumours which have different electrical properties than healthy breast tissue. The method includes steps for reducing skin reflections and for constructing a three-dimensional image using synthetic focusing which shows the presence or absence of microwave reflecting tissues.

In one embodiment, a system for custom-polarized photolithography illumination includes an illuminator operable to generate an illumination pattern of light, a polarizer unit operable to variably polarize the light, and a mask pattern defining photolithographic pattern features in two dimensions. The mask pattern is associated with a mask capable of transmitting at least a portion of the variably polarized light through the mask pattern.

An apparatus projecting 3D autostereoscopic images viewers. The apparatus includes a projector array with projectors each receiving an input image such as digital video and projecting an image based on the input image. A beam splitter with first and second surfaces is positioned such that the projected images strike the first surface and a portion (e.g., 50 to 95 percent) is transmitted through the beam splitter toward a screen with a retroreflective surface. The retroreflective surface reflects the splitter-transmitted portion back along the same path but with increased brightness. The light reflected from the retroreflective surface strikes the second surface of the beam splitter and is reflected toward a display viewing zone provided at about the focal points of the reflected projectors. A 3D image is perceivable to a viewer who positions his eyes at or near any of two or more viewing locations proximate to the projection surface.

A multi-display apparatus including a display unit 1 constituted by plural displays 11 detects that a viewer who is watching an image showed on the display unit 1 is present in a near region, and shows an image with the size thereof adjusted based on the detected result on the display unit 1. For example, the multi-display apparatus shows a small image on the display unit 1 by reducing the number of displays 11 used for image display when a viewer is present in the near region, allowing the viewer in the near region to easily see the image. Moreover, the multi-display apparatus shows a large image on the display unit 1 when no viewer is present in the near region, allowing a viewer outside the near region to easily see the image.

A transmitter for transmitting signals to targets and a receiver for receiving signals reflected from targets are included. The transmitter outputs CW signals for detecting direction and velocity of the target. The receiver performs: a function of receiving signals reflected from targets with a plurality of receiving antennas at the same time as transmitting from the transmitter, and performing spectral analysis with respect to receiving signals to thereby classify them by velocity component; a function of correlating signals of the receiving antenna systems; a function of integrating the signals correlation-processed; and a function of obtaining phase fronts of signals made incident on an antenna face from the phase differences of signals between receiving antennas, and performing two-dimensional FFT to the outputs to thereby measure the direction and velocity of the target.

In a face image capturing device, a focal point of a fixed-focus in-vehicle camera is set to a position where a circle of confusion with respect to a foremost face position is larger than the circle of confusion with respect to a rearmost face position. The rearmost face position is where the driver's face is positioned when a driver's seat is moved to the rearmost limit. The foremost face position is where the driver's face is positioned when the driver's seat is moved to the foremost limit. When the focal point of the in-vehicle camera is set to the above position, the focal point can be moved rearward to reduce the blurring of a face image at the rearmost face position. Even if the blurring of the face image at the rearmost face position is increased, a driver condition can be accurately determined at all times.

An image stabilizer has a base block, an inner frame for holding a CCD, an outer frame, a pair of horizontal leaf springs, a pair of vertical leaf springs, voice coil motors (VCMs) and a flexible printed circuit (FPC). Upon a shake of a digital still camera due to hand-held shooting, the VCMs shift the inner or outer frame while bending the horizontal or vertical leaf springs so that the CCD is shifted to counteract the camera shake. The FPC connected to the CCD and the VCMs is routed from the inner frame, through the horizontal leaf spring, the outer frame and the vertical leaf spring, and pulled out above the base block. The FPC is glued to the horizontal and vertical leaf springs, and elastically bent together with the horizontal and vertical leaf springs.

A CCD support mechanism includes a CCD holder for holding a CCD, a first printed circuit board having a first printed coil, a second printed circuit board having a second printed coil, a pair of horizontal leaf springs, and a pair of vertical leaf springs. When a camera shake occurs by hand-held shooting, a VCM composed of the first printed coil and a first stationary magnet shifts the CCD, while bending the horizontal leaf springs, to counteract the camera shake in a Y-axis direction. A VCM composed of the second printed coil and a second stationary magnet shifts the CCD, while bending the vertical leaf springs, to counteract the camera shake in an X-axis direction. Current values of the VCMs are determined by feedback control by using an output signal from a shake detector as a target value and a present position from a position detector as a measurement value.

A lens position adjustment system (10) permits adjustment of the position of a projection lens (5) relative to a projector (100) for making a Scheimpflug adjustment. The projection lens (5) has an optical axis (6). The system (10) comprises: a first support part (20) for fitting to, or forming part of, the projector (100); a second support part (40) for fitting to, or forming part of, the projection lens (5); and a connecting part (30). The connecting part (30) is pivotally connected to the first support part (20) and pivotally connected to the second support part (40) and configured to permit independent adjustment of the second support part (40) relative to the first support part (20) about two axes of rotation (7, 8) which intersect, and are perpendicular to, the optical axis (6) of the projection lens (5). A locking mechanism (28, 29, 51-58) is provided for securing a position of the second support part (40) relative to the first support part (20).

Disclosed is an imaging lens having a small F-number, high resolution, a sufficiently wide angle of view, and a small size.An imaging lens includes: a first lens with a meniscus shape having a concave surface facing an object side; a second positive lens; a third negative lens with a meniscus shape having a convex surface facing an image side; and a fourth lens having a convex surface facing the object side. The first to fourth lenses are arranged in this order from the object side. The imaging lens satisfies the following conditional expression:0.25<D / f<4.0(where D indicates the distance between the first lens and the second lens on the optical axis and f indicates the focal length of the entire system).

A camera body includes a body mount to which the lens unit can be mounted, a metal main frame supporting the body mount, an imaging element configured to convert an optical image of the subject into image data, an intermediate part disposed along a thermal conduction path formed between the main frame and the imaging element, and a metal heat radiating member connected to the intermediate part.

A camera body includes a body mount, an imaging element, an imaging element circuit board, a main circuit board, and a metal heat radiating plate. The body mount allows the lens unit to be mounted. The imaging element is disposed on the opposite side of the body mount from the side where the lens unit is mounted, and converts an optical image of the subject into image data. The imaging element circuit board is electrically connected to the imaging element and controls the imaging element.
