    Abstract: A method for sequential control of a diaphragm arrangement of a camera, the arrangement comprising a diaphragm, and an integrated IR cut filter always covering at least a portion of an aperture opening of the diaphragm, comprising: initiating closing or opening of the diaphragm; detecting an amount of incident radiation when the diaphragm has an initial aperture opening; shifting the aperture opening to an intermediate aperture opening to alter the ratio between visible light and infrared radiation passing the diaphragm; detecting an amount of incident radiation following the shift; calculating a composition of visual light and infrared radiation in the scene from the detected amounts of incident radiation and a calculated ratio between visible light and infrared radiation when having the initial aperture opening and the intermediate aperture opening, respectively; and shifting the aperture opening of the diaphragm to a new position.

    Abstract: The present disclosure relates to an imaging device and an imaging method that enable more appropriate exposure control to be performed quickly. An image sensor includes an image sensor in which an exposure detection pixel configured to output a pixel value to be used for detection of brightness of a subject and an effective pixel configured to output a pixel value effective for construction of an image are arranged in an imaging effective area to be utilized for imaging of the image; and an exposure control unit configured to control exposure time of the image sensor on the basis of the pixel value output from the exposure detection pixel. Furthermore, the pixel value of the exposure detection pixel has a higher dynamic range than the pixel value of the effective pixel. The present technology can be applied to an image sensor including AE control, for example.

    Abstract: A digital single-lens reflex camera that can reduce deterioration in image quality due to a camera shake or an object movement and easily pick up an image with a good image quality. In the digital single-lens reflex camera, when a body microprocessor judges that an object speed detected based on a detected object movement is smaller than a threshold value, a conversion lens camera shake correcting device in a conversion lens or a camera body shake correcting device in a camera body is controlled to carry out camera shake correction. If the object speed is equal to or more than the threshold value, the body microprocessor makes a digital signal gain setting unit high in gain so as to increase the ISO sensitivity or makes a shatter speed faster to set a shorter exposure time and has a plurality of images continuously picked up under different exposure conditions.
