A semiconductor component that receives incoming light includes an integrated circuit, a package and an optics unit. The optics unit may provide a pathway, either generally or selectively, for the incoming light to the photodetector circuitry of the integrated circuit and may modify the incoming light, as well. The optics unit may be either electrically active or passive. When active, the optics unit is coupled to the integrated circuit with a conductor. The optics unit may also include a liquid crystal device, a beamsplitter assembly, a lensing assembly or other filters, and/or apertures. The liquid crystal device can act as a shutter or a display and the optics unit may be a single module or a plurality of modules. The integrated circuit may also include shutter drive circuitry and image processing circuitry.

An image processing device is provided for still and video imaging systems which use a low number of samples per image pixel, preferably a single color component per each image pixel. The device includes an edge-dependent and edge-side-dependent color interpolation process, preferably implemented within the imaging system or within a host image processing computer hardware. The process reconstructs the missing color components of each said image pixel with high accuracy, because it is based on the detection of the spatial features present in the pixel neighborhood, thus providing sharp images without artifacts and with smooth transition in hue from pixel to pixel.

Edge-dependent interpolation method for color reconstruction in image processing devices

The invention is an imaging device having a high fill factor. The high fill factor is achieved by constructing the light sensors in a vertical fashion in the imaging device. The control circuitry of the light sensor is then contained inside the integrated circuit chip, rather than taking up area that could otherwise be used for light collection. The majority of the area on the surface of the IC chip is made up of light sensing elements, since the control circuitry is embedded in the IC chip. The control circuitry is connected to the light sensing devices through vias in the IC chip. The control circuitry of the chip is mainly contained within the die, rather than on it.

Light sensing system with high pixel fill factor

A camera system employs an electronic imager such as a Charged Couple Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS) array that captures a first portion of light and reflects a second portion of light reflected from a target subject. The light reflected by the electronic imager may be reflected towards film media or a color filter, for example. The electronic imager may include an integrated circuit, or a dielectric reflecting coating that acts to partially reflect incoming light reflected from the target subject. A display, such as an LCD (Liquid Crystal Display), may be utilized to determine which images are desirable or to identify which films to develop. Film writing circuitry that allows various types of information to be written may be utilized. The camera system further features an electronic imager shutter, and a film shutter for shuttering purposes. The film shutter can provide exposure control. The camera system additionally features a processing or control system that selectively controls using the electronic imager or the film media or both simultaneously. The camera system may also have a beamsplitter such as a prism, mirror or optical coating that transmits and reflects light from a subject towards an electronic imager and/or film media, respectively. In addition, the camera system can download digital images to a computer via interface circuitry.

Camera utilizing film and reflective imager

An imager reduces lighting induced flicker by setting its pixel integration time to an integral multiple of the periods between peak intensity of the lighting. In one implementation, flicker is reduced in a 30 Hz frame rate camera capturing an image lighted with 50 Hz lighting by setting the integration time to approximately 10 ms, the period between lighting intensity peaks.

Image flicker reduction with fluorescent lighting

A video compression method is provided and implemented in a pixel processing controller of a digital solid-state imaging device for maximizing throughput of digitized video data on a link between the digital solid-state imaging device and a host computer. The method performs separate luminance (Y) domain compression of the video data on a line-by-line basis, without storing video data lines or video data frames, and separate chrominance (Cr/Cb) domain averaging of the video data on a region-by-region basis without storing video data in video frames. The Y and Cr/Cb domain compression steps are implemented in the digital solid-state imaging device hardware for real time link transmission of the compressed video data to the host computer.
