An imaging apparatus acquires pixel signals for each region of a plurality of regions obtained by dividing an imaging plane having a plurality of pixels arranged in a two-dimensional pattern and detects a region among the plurality of regions in which a subject image has changed. The imaging apparatus determines an image capturing mode and controls to perform image capturing in the determined image capturing mode in response to the region in which the subject image has changed being detected and to output a captured image. The imaging apparatus determines the image capturing mode by selecting a first image capturing mode or a second image capturing mode based on the region in which the subject image has changed.

A device is operable to output, regarding a subject, a pair of captured images pertaining to binocular stereopsis. The device obtains, regarding a plurality of capturing systems arranged to be a predetermined distance apart, a group of captured images in which the subject is captured, wherein the device obtains, regarding at least one capturing system among the plurality of capturing systems, a plurality of captured images pertaining to luminous fluxes that have each passed a different pupil region, determines, regarding the pair of captured images, a baseline length to be set, and selects, from among the group of obtained captured images, the pair of captured images based on the determined baseline length to be set and output the pair of captured images.

An imaging apparatus acquires pixel signals for each predetermined-size partial region of an imaging plane and for detecting a region among the regions of the imaging plane in which a subject image has changed, the number of acquired pixel signals being less than the number of pixels included in the partial region, and controls to perform image capturing in response to detection of the region in which the subject image has changed, and to output a captured image based the pixel signals. The imaging apparatus acquires pixel signals from each partial region of the imaging plane by, when pixel signals are to be acquired from a first partial region of the imaging plane, acquiring pixel signals from a second partial region that is adjacent to the first partial region and partially overlapped with the first partial region.

An image pickup apparatus that performs accurate correction processing for a pixel that outputs a non-reproducible high-level signal having a continuity with respect to an adjacent pixel is provided. The image pickup apparatus extracts data corresponding to a pixel of an image pickup element that generates an output value equal to or more than a predetermined value, and determines, within a predetermined area of a captured image, whether a predetermined number or more of pixels that generate an output value having the predetermined level are continuously adjacent to one another in the same direction, irrespective of the color received by the pixel. Then, if it is determined that the predetermined number or more of pixels are continuously adjacent to one another in the same direction, the pixels are indicated as targets and the outputs of the target pixels are corrected.

Image pickup apparatus and control method for correcting data output from pixels of an image pickup element

An image pickup apparatus capable of accurately detecting a flicker in a short time period without regard to a state of object and a photography scene. A signal processing circuit reads out an n-th line of an image subjected to collective reset/collective transfer readout, reads out an n-th line of an image subjected to rolling readout, and subtracts an output of a pixel section of a particular column of the n-th line of the image subjected to the rolling readout from an output of a corresponding pixel section of the image subjected to the collective reset/collective transfer readout. The signal processing circuit determines that a flicker is generated, if there is a differential value not less than a predetermined threshold value between each pair of outputs from the pixel sections of the same line and if there is a periodicity in an image vertical direction.

In a radiographic imaging apparatus capable of performing a first imaging in which radiographic imaging is performed with a first X-ray dose and a second imaging in which radiographic imaging is performed at a second X-ray dose that is less than the first X-ray dose, the timing corresponding to a particular phase of a periodically moving organ as a subject to be imaged is predicted, and the first imaging performed at the predicted timing and the second imaging performed a predetermined number of times before and after the predicted timing are repeated. Through this repetition, a shift between the timing of the particular phase that is recognized from images acquired through the execution of the first imaging and the second imaging and the predicted timing is detected, and the predicted timing is corrected based on the detected shift.
