摘要： An image capturing apparatus includes a plurality of photoelectric conversion elements, a first selection unit, and a second selection unit. Each of the photoelectric conversion elements includes an avalanche diode and a counter. The photoelectric conversion elements have a first photoelectric conversion element and a second photoelectric conversion element. The first selection unit controls the first photoelectric conversion element. The second selection unit controls the second photoelectric conversion element. The first and second selection units are controlled by a first control line and a second control line. In a first mode, the second selection unit controls the second photoelectric conversion element to be brought into a state where no signal is read from the second photoelectric conversion element. In a second mode, the second selection unit controls the second photoelectric conversion element to be brought into a state where a signal is read from the second photoelectric conversion element.

摘要： An image sensor includes a pixel including a reset circuit and a floating diffusion node, and outputting a pixel signal that is generated based on a voltage at the floating diffusion node, the pixel signal including a reset output that is generated based on the voltage at the floating diffusion node being reset by the reset circuit. The image sensor further includes a sampler sampling the output pixel signal to generate a sampling signal having a time interval corresponding to a magnitude of the output pixel signal, and a counter counting the generated sampling signal, based on a counter clock, to generate a counting value corresponding to the time interval of the sampling signal. The sampler samples the reset output of the output pixel signal n times to generate first to n-th reset sampling signals, where n is an integer of 2 or more.

摘要： An image capturing apparatus comprises a plurality of light-receiving circuits, each outputting a pulse signal in response to a photon being incident; a plurality of counter circuits that count the respective pulse signals output by the plurality of light-receiving circuits; and a correction circuit that corrects counts from the plurality of counter circuits and outputs the corrected counts as image data. The correction circuit calculates a correction coefficient on the basis of counts obtained by the plurality of counter circuits in a state where pulse widths of the pulse signals differ or under conditions where generation frequencies of the pulse signals differ, and performs the correction using the correction coefficient.

摘要： A method and apparatus for capturing digital video includes displaying a preview of a field of view of the imaging device in a user interface of the imaging device. A sequence of images is captured. A main subject and a background in the sequence of images is determined, wherein the main subject is different than the background. A sequence of modified images for use in a final video is obtained, wherein each modified image is obtained by combining two or more images of the sequence of images such that the main subject in the modified image is blur free and the background is blurred. The sequence of modified images is combined to obtain the final video, which is stored in a memory of the imaging device, and displayed in the user interface.

摘要： The present disclosure relates to a solid-state image pickup apparatus, a correction method, and an electronic apparatus, enabled to suppress an apparent uncomfortable feeling of an image output from a solid-state image pickup apparatus in which pixels of different OCL shapes are mounted mixedly. A solid-state image pickup apparatus according to an aspect of the present disclosure includes a pixel array in which a first pixel in which an OCL (On Chip Lens) of a standard size is formed and a second pixel in which an OCL of a size different from the standard size is formed are present mixedly, and a correction section that corrects a pixel value of the first pixel that is positioned in the vicinity of the second pixel among the first pixels on the pixel array. The present disclosure can be applied to, for example, a CMOS image sensor.
