摘要： Automatic exposure adjustment control that is not affected by smear. An image pick-up device control system of an electronic shutter, a lens aperture and an automatic gain control. Smear amount is calculated precisely even if weak smear phenomenon does not reach a saturation level. When smear is detected, a first electronic shutter speed and a first lens aperture value are measured and first color information integral values of red, green and blue are measured in a predetermined color measurement area of an effective pixel region of an image pick-up unit. The electronic shutter speed is slowed to a predetermined amount to provide the same exposure as the exposure at the first electronic shutter speed and first lens aperture, and the lens aperture is narrowed only to that amount to measure the second color information integral values of the red, green and blue in the color measurement area. The smear amount is calculated from the color integral values of the red, green and blue.

摘要： A distance calculation method and an imaging device that can be applied to a digital camera. The method includes calculating a distance between a point corresponding to an optical axis of a lens sub-system of the imaging device and an input point, and using the calculated distance to correct defects such as shading that occur in formed images due to peripheral light fall-off in the lens sub-system. The distance is approximated by a polygon having five or more sides, preferably having 8 or 16 sides. The distance is calculated by a disclosed function having constant coefficients, so that distances can be calculated by simple hardware.

摘要： When pixel signals are separately read from a plurality of horizontal signal lines to achieve high-speed processing, color difference in image signals and stripes are eliminated. In the operation of reading the pixel signals from the (2n)th row, the pixel signals from R pixels on odd columns are output to an output system A through a horizontal signal line (60A). On the other hand, the pixel signals from Gr pixels on even columns are output to an output system B through a horizontal signal line (60B). In the operation of reading the pixel signals from the (2n+1)th row, the pixel signals from Gb pixels on the odd columns are output to the output system B through the horizontal signal line (60B) by the switching operation in a switching circuit (50). Similarly, the pixel signals from B pixels on the even columns are output to the output system A through the horizontal signal line (60A) by the switching operation in the switching circuit (50).

摘要： The present invention relates to apparatuses and methods for image processing, recording media, and programs in which extraction processing utilizing all pixels can be conducted. When a horizontal-component low-pass filter performs (1, 0, 1, 0, 1)/3 filtering with one of the green pixels in the first line as a target pixel, green pixels are multiplied by 1, red pixels are multiplied by 0, and the sum of the pixel values is divided by 3. As a result, a simple average of the target pixel and the adjacent green pixels is calculated. When one of the red pixels in the first line is defined as a target pixel, a simple average of the target pixel and the adjacent red pixels is calculated in the same manner. Similarly, green and blue pixels in the second line are filtered. Every third pixel of the horizontal components is then extracted in a 1/3 horizontal-extraction unit to generate an extracted-pixel group composed of pixels each having the simple-average value of every third pixel as a target pixel and the adjacent pixels of the same color. The present invention is applicable to digital cameras.

摘要： The present invention relates to an image processing apparatus and method in which more faithful colors are reproduced and noise is reduced, and to a method of manufacturing the image processing apparatus. A four-color color filter 61 is formed of a total of four filters, that is, an R filter that allows only red light to pass through, a B filter that allows only blue light to pass through, and a G1 filter that allows only green light in a first wavelength band to pass through, and a G2 filter, having a high correlation with the G1 filter, that allows only green light in a second wavelength band to pass through, the four filters defining a minimum unit. The G1 filter and the G2 filter are arranged at mutually diagonal positions within the minimum unit. RGB signals are generated in accordance with four kinds of signals which are transmitted through the four-color color filter 61 and which are obtained by an image sensor. The present invention can be applied to an image processing apparatus such as a digital camera.

摘要： A picture taking apparatus and a chromatic aberration correcting method are provided in which a satisfactory correction processing can be performed even when the camera shake correction is simultaneously performed. An output signal from a camera-signal processing circuit 4 is selected by a selector switch 5 and is supplied to a chromatic aberration correcting unit 6. On the other hand, an angular velocity due to the camera shake is detected using sensors 7P, 7Y and the detected signal is supplied to a camera shake correcting vector calculating unit 9 in control microcomputer 8. A driving state of a camera lens 1 such as a zoom focal length and focal position is supplied to a conversion-ratio calculating unit 10. An optical axis centered shift vector of camera lens 1 is obtained from the camera shake correcting vector and is supplied to the above unit 6. A conversion ratio of each color is supplied to the above unit 6. A signal corrected by the above 6 is compressed by data compression circuit 15 and supplied to a recording medium of a recording and reproducing unit 17 for recording. A signal reproduced therefrom is decompressed by a data expansion circuit 18 and supplied to the selector switch 5. Accordingly the picture-quality deterioration caused in the miniaturized camera lens can be compensated by processing the captured image signal, and also a satisfactory correction processing can be performed even when the camera shake correction is performed simultaneously.

摘要： A wafer of the invention is a silicon wafer of 0.02 &OHgr;cm or less in resistivity for deposition of an epitaxial layer, and the number of crystal originated particles (COP) and the number of interstitial-type large dislocation loops (L/D) are respectively 0 to 10 per wafer. A wafer of the invention is an epitaxial wafer having an epitaxial layer being 0.1 &OHgr;cm or more in resistivity and 0.5 to 5 &mgr;m in thickness formed on this wafer by means of a CVD method. A wafer of the invention is OSF-free and hardly makes traces of COP and L/D appear on the surface of an epitaxial layer when the epitaxial layer is formed. By heat treatment in a semiconductor device manufacturing process after the epitaxial layer is formed, BMDs occur uniformly and highly in density in the wafer and a uniform IG effect can be obtained in the wafer.
