摘要: The present disclosure provides image capture devices and associated methods that feature intelligent use of hardware-generated statistics. An example image capture device can include an imaging hardware pipeline that generates frames of imagery. The imaging hardware pipeline can generate one or more hardware-generated statistics based at least in part on, for example, the raw image data captured by the image sensor or intermediate image data within the pipeline. The image capture device can analyze the hardware-generated statistics to determine one or more metrics for the raw image data or the image. The image capture device can determine a downstream operation of the image capture device relative to the image based at least in part on the metrics determined from the hardware generated statistics.

摘要: The dynamic range of a pixel is increased by using selective photosensor resets during a frame time of image capture at a timing depending on the light intensity that the pixel will be exposed to during the frame time. Pixels that will be exposed to high light intensity are reset later in the frame than pixels that will be exposed to lower light intensity.

摘要: An imaging device and method with improved white balance control are disclosed. An image of an object is captured by an imaging element that includes a plurality of pixel output units that receives incident light that is incident without passing through either of an imaging lens and a pinhole. Each pixel output unit outputs one detection signal indicating an output pixel value modulated by an incident angle of the incident light, and on the basis of a detection signal acquired by the image capturing and acquired in the pixel output units, a white balance coefficient that is used for correcting a white balance of a restored image restored from the detection signal is set. The present disclosure can be applied to, for example, an imaging element, an imaging device, an image processing device, an electronic device, a system, or the like.

摘要: An imaging device includes: an imaging element that outputs an image signal in a nondestructive manner; an image processor that performs predetermined processing on the outputted image signal to generate image data; and a controller that controls the image processor. Under control of the controller, the image processor reads out image signals from the imaging element a plurality of times within one exposure period, calculates a target gain value based on a target level and an added signal, and multiples the added signal by the target gain value to generate the image data. The target level is calculated based on a signal level of a last read-out image signal in one exposure period. The added signal being obtained by adding up the image signals read out the plurality of times.
