    摘要： An image-taking apparatus generates an output image from a photographed image obtained by photographing and displays this output image on a display screen of a display section. The image-taking apparatus includes a recognition processing section for recognizing a specific subject (facial region of a person, or a facial component such as eyes) included in the photographed image. Referring to results of this recognition, the image-taking apparatus evaluates the dimension of the specific subject in each photographed image. If the dimension evaluated is relatively large, a relatively small magnification ratio to be employed upon the generation of the output image from the photographed image is provided. If the dimension evaluated is relatively small, a relatively large magnification ratio to be employed upon the generation of the output image from the photographed image is provided. As a result, the dimension of the specific subject in the output image is kept substantially constant.

    摘要： The exposure time calculator calculates exposure time of image sensor based on an aperture value corresponding to a diaphragm and brightness of an object. The predetermined time calculator calculates predetermined time based on a focal length of a lens and a predetermined coefficient. The shooting mode determining unit determines execution of multiple-exposure shooting to obtain a composite image of the object by obtaining multiple object images and then combining the multiple object images in a case where the exposure time is equal to or longer than the predetermined time. The motion detector detects motion among the multiple object images in the multiple-exposure shooting. The predetermined coefficient calculator updates a predetermined coefficient based on the detected amount of motion.

    摘要： There is provided an imaging apparatus and an imaging method capable of matching coordinate positions of a plurality of images to be synthesized with each other when generating an image having a wide dynamic range by synthesizing the plurality of images each having a different exposure condition. When a luminance adjustment circuit adjusts a luminance value of each of reference image data and non-reference image data, a displacement detection circuit detects displacement between the reference image data and non-reference image data. After a displacement correction circuit corrects coordinate positions of the non-reference image data on the basis of the detected displacement, an image synthesizing circuit generates synthesized image data composed of reference image data and non-reference image data.

    摘要： A black level correction circuit for a video camera using a solid state image pickup device includes: means comparing an average luminance on each horizontal line in an optical black region of a reference black image with an average luminance on the corresponding horizontal line in an optical black region of an input image to thereby obtain a gain on the horizontal line in order to equalize an optical black level of the reference black image with an optical black level of the input image; means multiplying each of pixel values on each horizontal line in an effective pixel region of the reference black image by the obtained gain on the corresponding horizontal line; and means subtracting each pixel value obtained by the multiplication from a pixel value of the corresponding pixel in the effective pixel region of the input image.
