A method for determining impedance includes receiving a time varying voltage signal from a biosensor and receiving a time varying current signal from the biosensor. The time varying voltage signal and the time varying current signal are transformed to a domain that represents complex values. The impedance representative of the biosensor based upon the transformed time varying voltage signal and the time varying current signal is calculated.

Aspects of the present invention are related to systems and methods for region-based up-scaling, and in particular, for up-scaling still images and video frames that contain graphical elements.

Methods and systems for region-based up-scaling

A method of backlighting a liquid crystal display so as to improve the quality of the image displayed by the liquid crystal display. The method may vary the luminance of a light source illuminating a plurality of displayed pixels and vary the transmittance of a light valve of the display.

Liquid crystal display with modulation for colored backlight

An upscaling (upsampling) technique for digital images and video for presentation on a display. An image at a first resolution may be separated into a plurality of channels. Each channel may be upsampled to a higher resolution. The plurality of channels may then be combined to form an image at the higher resolution.

Optimal hiding for defective subpixels

An image processing system processes light conveying visual pattern information represented by individual light rays. The system includes an optical assembly having an input surface and an output surface. The input and output surfaces define a plurality of input and output positions, respectively, for the light rays to enter and exit, respectively, the assembly. The assembly includes a light-shifting apparatus operable so that a respective one of the light rays entering a respective one of the input positions is selectively shiftable by the apparatus in a first direction and, subsequently, in a second direction angled with respect to the first direction from a preceding one to another of the output positions. The assembly is further operable so that following each shifting operation, a respective one of the light rays transmitted by the assembly from an arbitrarily selected one of the output positions is solely derived from the light received from a single one of the input positions.

A system for improving the display resolution by the reduction of chromatic aliasing.

System for improving display resolution

A technique for describing an image where a number of test areas are located on the image.

Method for image description using color and local spatial information

A system constructs a high resolution image from a plurality of low resolution images where each of the low resolution images includes a plurality of color planes. The system receives the plurality of low resolution images where the plurality of color planes of each of the low resolution images are spatially arranged in at least a partially non-coincident manner. Motion data representative of motion of at least a portion of the low resolution images is determined. The high resolution image is constructed, having a resolution greater than the low resolution images, based upon the non-coincident color planes of the low resolution images, together with the motion data.
