Bayer data is captured by a CCD and is store in a memory. Image data is read out from the memory in units of nine lines starting with (4n+1)-th (n: integer) line. YUV data of one pixel is formed based on 5.times.5 pixels in the read Bayer data. Thus, the YUV data is formed in units of five lines. The YUV data is enlarged by a pixel number converting unit.

An object of the present invention is to realize an image processing technique of making chromatic aberration correction excellently function and capable of efficiently correcting a chromatic aberration and to reduce storage capacity of parameters used for the chromatic aberration correction. It is constructed so that an image processing unit concurrently performs a chromatic aberration correcting process of correcting a chromatic aberration by an image capturing optical system and a color inter...

An interpolation method for generating pixel color is used for color generating of an array composed of red, green, and blue pixels so that each pixel has red, green, and blue components. After signals of the pixel array are received, the signal trends in the horizontal and vertical directions around pixels are first determined. Next, two pixels adjacent to each pixel are calculated along the direction of minimum variation to complement data of the pixel location using this calculated value. Sub...

A fast method of color interpolation of pixels of an image acquired by a color filtered digital sensor uses a very simple cost function that nevertheless produce interpolated images of good quality. The cost function is computationally simpler because it does not require the calculation of powers and square roots. The triangulation algorithm may be executed in far less time, while practically ensuring the same performance. The triangulation algorithm on average may use only two iteration steps. ...

For processing image data generated for a color filter array, classifiers are generated from the image data. A predetermined color component is determined by directional-interpolating the image data depending on the classifiers. Chrominance components are generated from linear-interpolated image data and the directional-interpolated predetermined color component. The chrominance components are directional-interpolated, and color components are extracted from the directional-interpolated chromina...

A digital camera includes a sensor (205) for sensing an image and producing a first signal. A Bayer pattern producer (210) is coupled to the sensor and structured to produce a Bayer pattern from the first signal. The Bayer pattern is then split (212) into separate color channels. A color interpolator (214) is structured to perform a modification on only one of the color channels produced by the splitter (212). A compressor (220) then compresses the interpolated and non-interpolated color channel...

A digital camera having a single image sensor made up of an array of filtered photosites used to capture non-visible light wavelengths in addition to the standard red/green/blue (RGB) or other visible light intensity values is presented. Essentially, this is accomplished using a separate filter disposed over each photosite that exhibits a light transmission function with regard to wavelength which passes only a prescribed range of wavelengths--some passing light in the visible light spectrum and...

Through an image pick-up lens 1, image light is focused on an image pickup surface of an image pickup unit 2 for which a primary color filter is provided. An electrical signal removed from the image pickup unit 2 is supplied to an A/D conversion circuit 3 to be converted into raw data of each primary color and is supplied to a first camera signal processing circuit 61 without any change. In the first camera signal processing circuit 61, only basic video signal processing such as gamma-correction...

Camera signal processing comprising interpolating, at least on two directions, pixel data based on an imaging signal from a solid-state image sensor in which an imaging light enters through a color filter having a different spectral characteristic for each pixel separately generating interpolated pixel data in the directions, detecting a correlation value indicative of a degree of correlation in each of the directions of the interpolated pixel data, normalizing the correlation value of each of t...
