A photographing method and apparatus for photographing a fluorescent image, composed of fluorescent light emitted by a living tissue that has been illuminated by a stimulating light, as an image having a higher S/N ratio. Fluorescent light emitted by a living tissue that has been illuminated by a stimulating light emitted from a light source and propagated along an endoscope enters an image fiber. The fluorescent light entering the image fiber is propagated along the image fiber to the output fa...

An imaging apparatus for outputting image signals by photoelectrically converting an image formed at an optical system by an image sensor array having a color filter array having several spectral transmittance disposed in front thereof, including: mode setting means capable of setting at least one mode among an all-pixel read mode for effecting readout of all the pixels of at least one horizontal line, an intermittent read mode for effecting readout in a thinned-out manner of pixels to be read o...

The invention relates to an array of sensor elements, wherein the sensor elements are provided to detect electromagnetic radiation such as X-radiation or light, and in doing so to generate a charge signal corresponding to the intensity of the radiation. A sensor element further comprises means enabling the incoming dose of radiation to be determined. In the array, the sensor elements form groups, so that the outputs of all sensor elements of a group are coupled. This on the one hand enables a de...

A binning circuit and related method, wherein pixel signals from column circuits in a sensor circuit are sampled and interpolated. The binning circuit samples analog pixel and reset signals from different sensor circuit column lines. Once a predetermined number of column lines are sampled in the binning circuit, the sampled pixel signals are averaged together in one operation, while the reset signals are averaged together in another operation.

An imaging apparatus including: a single-chip image sensor with a color filter array and capable of intermittent readout operation in horizontal and vertical directions; an intermittence control means for controlling the intermittent readout operation of the image sensor; and an interpolation means for processing signals read out from the image sensor in a thinned out pattern designated by the intermittence control means to form a reduced image consisting of trichromatic components; wherein the ...

A digital still camera includes an image pickup device for photographing a subject, and an image processor adapted to drive and control the image pickup device, to process photographic signals outputted from the image pickup device and to record the processed images in a recorder. The image processor includes digitally zooming unit for selected a part of a photographic image plane photographed by the image pickup device and digitally zooming said part of the image. The image pickup device posses...

An image pickup control unit specifies a scan area of a frame based on a scaling factor for electronic zooming. An image sensor converts incoming light signals into electric signals by performing reset scanning on each line of the specified scan area of the frame, and accumulates each of the electric signals, and reads the electric signals accumulated thereby by performing read scanning to output them as image data. In response to an instruction for changing a horizontal scanning period and a ve...

A circuit includes a decoder for receiving an address within an address space of a processor and for accessing a pixel in an active pixel sensor array based on the address. The decoder maps the active pixel sensor array to the address space. The circuit can also provide sequencing of these addresses such that a group of pixels can be read out without additional addressing from a processor. There is also provided a method of processing pixel imperfections in real time. Pixel integration can be pr...

An integrated image sensor for acquiring and processing electrical signals representative of an object comprising a photosite array configured to convert light into the electrical signals, an A/D converter configured to convert the electrical signals into digital data, and logic integral with the image sensor configured to scale the digital data by a non-integer-scaling factor. A method for acquiring and processing image data with an integrated image sensor comprising the steps of capturing, via...

In order to form a magnified image without degradation of a resolution, signals of pixels contained in a first image pickup area are read through addition of n (n is a natural number) pixels, and signals of pixels contained in a second image pickup area smaller than the first image pickup area are read through addition of m (m<n, m is a natural number) pixels or without addition.
