Abstract: PROBLEM TO BE SOLVED: To realize color reproduction with a higher fidelity and noise reduction.
SOLUTION: A color filter 61 of 4 colors is constituted by four filters as the minimum unit i.e., an R filter for transmitting only the red light, a B filter for transmitting only the blue light, a G1 filter for transmitting only the green light in a first wavelength band, and a G2 filter having a high correlation with the G1 filter and transmitting only the green light in a second wavelength band. Also, the G1 and G2 filters are disposed in a diagonalized position in the minimum unit. An RGB signal is generated on the basis of the four kinds of signals which transmit the filter 61 and is obtained by an image sensor. This apparatus can be applied to an image processing device such as a digital camera.

Abstract: PROBLEM TO BE SOLVED: To provide an image pattern correction method and an imaging device that can cope with image pattern correction with the same circuit, even if number of pixels of an image pickup section differs. SOLUTION: Horizontal and vertical image signals from a signal generator(SG) 1 are fed to a semiconductor imaging element (CCD) 3 through a timing generator(TG) 2. Furthermore, horizontal and vertical counts from the signal generator 1 are fed to a distance calculation block 4, where a distance from optical axis center position information received from terminals 5X, 5Y is calculated. A calculated distance(d) is fed to a converter(conv) 6, which gives a converted distance according to information of number of pixels of the semiconductor image pickup element 3 received from a terminal 7 to a look-up table(LUT) 8, from which correction coefficients corresponding to the distance from, e.g. the optical axis center position is extracted. The correction coefficient is fed to a correction block 9, which applies correction to a signal of each pixel read from the semiconductor imaging element 3. Furthermore, the corrected signal is fed to a camera signal processing block 10, in which an output image signal (Y/C output signal) is extracted at a terminal 11.

Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of change of hue. SOLUTION: In a method of image processing, histograms of luminance signal Y are generated (step S1), a cumulative histogram is generated with cumulating the histograms to generate a corrective LUT for luminance signal with a logarithmic approximation of the corrective LUT (step S2). A corrective parameter LUT for color-difference signal is generated referring to the corrective LUT (step S3). A corrected luminance signal Y0 is acquired adopting an inputted signal Y to the corrective LUT (step S4). A corrective parameter k is acquired adopting the inputted signal Y to the corrective parameter LUT (step S5). Corrected color-difference signals Cr0, Cb0 are acquired multiplying the inputted color-difference signals Cr, Cb by the parameter k (step S6).

Abstract: PROBLEM TO BE SOLVED: To conduct efficient signal processing corresponding to an operating mode. SOLUTION: A CCD interface 21a interleaves a horizontal component of image data fed from an image generating section to 1/3 in a finder mode and applies gamma correction or the like to the thinned data and gives the result to a camera DSP 21c. The camera DSP 21c applies data conversion and resolution conversion to the image data after being thinned to convert the data into image data Y, Cb, Cr, which are fed to an image memory 32 via a memory controller 22. In a recording mode, the CCD interface 21a applies thinning and gamma correction or the like to the image data from the image generating section and writes the resulting data to the image memory 32 through the memory controller 22. The camera DSP 21c reads the image data from the image memory 32 through the memory controller 22, applies data conversion to the image data and writes the resulting data to the image memory 32 through the memory controller 22.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a false color signal in an image, even in a band where a correlation cannot be detected by selecting the color difference signal whose value is the minimum among the color difference signals of interpolation pixel data in respective directions and the color difference signals of interpolation pixel data, to which the correlation values in the respective directions are added and generating an image signal based on selected interpolating pixel data. SOLUTION: An image data interpolation part 15 interpolates image data from a gamma-correction circuit 14 for respective pixels, generates respective interpolation pixel data and outputs them to a weight addition circuit 22. The weight addition circuit 22 weights interpolation pixel data in a vertical direction and a horizontal direction, based on the vertical correlation value from a correlation emphasis/reduction circuit 21, adds them and outputs them to a color difference signal suppression part 25 via a Y/C conversion part 24. The color difference signal suppression part 25 selects interpolation pixel data, whose absolute value of the color difference signal is the minimum among inputted interpolation pixel data so as to output it. Thus, the folded distortion of a color can be prevented, even in a frequency band where a correlation cannot be seen.

Abstract: PROBLEM TO BE SOLVED: To generate a luminance signal and a color difference signal, without deteriorating the resolution of an image by weighting interpolation picture element data in respective directions with correlation values in the respective directions and adding weighted interpolation pixel data, thereby generating interpolated pixel data. SOLUTION: The horizontal direction/vertical direction interpolation circuits 15a and 15b an image data interpolation part 15 calculate interpolation pixel data in a horizontal direction and a vertical direction by the use of a prescribed filter from a pixel corresponding to respective pixels, arranged in a matrix form from a gamma-correction circuit 14 and output them to a weighting addition circuit 22. The weighting addition circuit 22 weights interpolation pixel data in the vertical direction and the horizontal direction, based on the vertical correlation value from a correlation emphasis/reduction circuit 21, adds them, generates interpolation pixel data weighted in the vertical direction and the horizontal direction and outputs them to a Y/C conversion part 24. The Y/C conversion part 24 converts inputted interpolated pixel data into a luminance signal and a color difference signal.
