摘要： An imaging apparatus includes a first output unit configured to output, outside the imaging apparatus, a first image that an image sensor, an imaging region of which is divided into a plurality of regions, has captured while an exposure condition is controlled for each of the plurality of regions, and a second output unit configured to output, outside the imaging apparatus, exposure information for each of the plurality of regions, the exposure information indicating the exposure condition to be applied to the corresponding one of the plurality of regions when the first image is captured. The second output unit is configured to complete outputting exposure information for a region to be subjected to exposure correction processing in the first image, out of the plurality of regions, before the first output unit completes outputting an image of the region to be subjected to exposure correction processing.

摘要： Pixel values are read out of an OB pixel region under a predetermined exposure condition, and predetermined processing is performed on the pixel values to derive a dark current component value. The dark current component value of a segmented pixel region is estimated from the OB dark current component value by taking into account the difference between the exposure conditions of the OB pixel region and the segmented pixel region. Specifically, a conversion ratio for calculating the dark current component value from the OB dark current component value is derived based on the ratios between exposure time and gain in the exposure conditions of the two pixel regions. This conversion ratio is applied to the pixel values of the OB pixel region or the OB dark current component value calculated from them to thereby calculate an estimated dark current component value for the exposure condition of the segmented pixel region.

摘要： An imaging device 100 comprises an imaging unit 120 including a plurality of pixels 10, respectively including photoelectric converters 13 and charge accumulation nodes 41 that accumulate signal charge therein, and a signal readout circuit that reads out signals corresponding to the signal charge accumulated in the charge accumulation nodes 41. The imaging unit 120 outputs image data based on the signals. The imaging device 100 comprises an image processing unit 140 that processes the image data output by the imaging unit 120. The imaging unit 120 sequentially outputs a plurality of pieces of image data in one frame period by performing readout nondestructively. The image processing unit 140 generates difference image data by determining a difference between two pieces of image data, selects output image data IS from initial image data and the difference image data, and combines the output image data IS and normal readout image data IL included in the plurality of pieces of image data, to generate combination-result image data IHDR.

摘要： A photoelectric conversion device includes a photoelectric converter, a first node configured to be supplied with charges from the photoelectric converter, an amplification transistor configured to output a signal corresponding to a voltage of the first node, a first transistor configured to open/close a path between the first node and a second node not included in a path from the electric converter to the first node, and a second transistor configured to open/close a path between the second node and a third node. A second capacitance which is added to the second node when the second transistor is set in a conductive state is larger than a first capacitance which is added to the first node when the first transistor is set in a conductive state.

摘要： Provided is an imaging device capable of adaptively acquiring a captured image according to an imaging condition. An imaging device (1) according to an embodiment includes: an imaging unit (10) that includes a pixel array (110) including a plurality of pixel groups each including N × N pixels (100) (N is an integer of 2 or more), and outputs a pixel signal read from each pixel; and a switching unit (14) that switches a reading mode in which the pixel signal is read from each of the pixels by the imaging unit, in which the switching unit switches the reading mode between an addition mode in which the pixel signals read from the N × N pixels included in the pixel group are added to form one pixel signal and an individual mode in which each of the pixel signals read from the N × N pixels included in the pixel group is individually output.

摘要： The present disclosure relates to a solid state image sensor and electronic equipment that enable degradation in image quality of a captured image to be suppressed even if any pixel in a pixel array is configured as a functional pixel for obtaining desired information in order to obtain information different from a normal image.
In a plurality of pixels constituting subblocks provided in an RGB Bayer array constituting a block which is a set of color units, normal pixels that capture a normal image are arranged longitudinally and laterally symmetrically within the subblock, and functional pixels for obtaining desired information other than capturing an image are arranged at the remaining positions. The present disclosure can be applied to a solid state image sensor.
