摘要： Accurately suppress chromatic aberration arising in a subject image is described. An image signal, which is obtained by a lens and a CCD and pertains to a subject image, is subjected to white balance adjustment performed by a white balance adjustment circuit. The signal is supplied to a color-blurring detection circuit before undergoing gamma correction. The color-blurring detection circuit has a low slice circuit, a high-pass filter, and a high clip circuit; detects an edge portion of a highlight of a G signal constituting the image signal; and supplies the detected edge portion as a color-blurring detection signal to a color-blurring suppressor circuit disposed subsequent to a γ correction circuit. The color-blurring suppressor circuit corrects color-difference signals CB, CR, which have been subjected to gamma correction, by use of the color-blurring detection signal, thereby suppressing the color-blurring having arisen in the edge of a highlight of the image.

摘要： An image processing apparatus is provided which performs image restoration as necessary while a computing processing burden based on an image restoration algorithm is reduced. RAW data of a blurred image is input to an RGB interpolation section. The RGB interpolation section generates an R component image, a G component image, and a B component image based on the RAW data. The G component image is input to an image restoration processing section and the R and B component images are input to an RGB to YCC section. The image restoration processing section performs an image restoration process based on a predetermined image restoration algorithm by using a PSF image representing a predetermined point spread function. The RGB to YCC section generates a brightness component image Y and color difference component images CR and CB based on the G component image having been subjected to the image restoration process and the R and B component images which was not subjected to any image restoration process.

摘要： A flashlight-exposed region is distinguished from an unexposed region during flash (or stroboscopic) photography. A region determination section of a digital camera acquires a preview image and a preview image acquired by firing preliminary flashlight. A region where a difference between the preview images exceeds a threshold value is determined to be a flashlight-exposed region. The region determination section acquires the preview image and an image captured during firing of primary flashlight. After the preview image has been resized, the preview image is compared with the captured image, and a region where the difference between the images exceeds a threshold value is determined to be a flashlight-exposed region.

摘要： An error in a camera having angular velocity sensors is eliminated. A camera is placed on a rotating table and rotated, angular velocities are detected by angular velocity sensors, and a CZP chart is photographed. The motion of the camera is computed as a locus of motion of a point light source on an imaging plane from the outputs from the angular velocity sensors. The inclination of the locus motion is compared with the inclination of a zero-crossing line which has been obtained by subjecting the photographed image to Fourier transformation, to thus compute angles of relative inclination of the angular velocity sensors with respect to the image sensor. Further, when no coincidence exists between the zero-crossing line of the data into which a PSF has been Fourier-transformed and a zero-crossing line of the data into which a photographed image has been Fourier-transformed, a computer computes a correction coefficient from a proportion of an interval between the zero-crossing lines, on condition that an error is included in the angular velocity sensors or the focal length of a photographing lens, and the error is eliminated.

摘要： Inclinations of angular velocity sensors attached to a camera are detected, and outputs from the angular velocity sensors are calibrated. A camera is placed on a rotating table and rotated, angular velocities are detected by angular velocity sensors, and a CZP chart is photographed. The motion of the camera is expressed as a locus of motion of a point light source on an imaging plane from the outputs from the angular velocity sensors. The inclination of the locus motion is compared with the inclination of a zero-crossing line which has been obtained by subjecting the photographed image to Fourier transformation, to thus compute angles of relative inclination of the angular velocity sensors with respect to the image sensor.
