To suppress a difference in brightness and darkness in a captured image caused by a difference in an exposure start time by a rolling shutter even if the exposure period is not changed. Provided is an imaging device including a gain setting unit configured to set a gain for each line in which a plurality of pixels is arrayed, the plurality of pixels being two-dimensionally arranged in a matrix in an image sensor, on the basis of diaphragm drive information regarding a diaphragm drive locus representing a time-series change in a diaphragm value. Thereby, the difference in brightness and darkness in a captured image caused by the difference in an exposure start time by a rolling shutter can be suppressed even if the exposure period is not changed.

Disclosed are devices, systems and methods for capturing an image. In one aspect an electronic camera apparatus includes an image sensor with a plurality of pixel regions. The apparatus further includes an exposure controller. The exposure controller determines, for each of the plurality of pixel regions, a corresponding exposure duration and a corresponding exposure start time. Each pixel region begins to integrate incident light starting at the corresponding exposure start time and continues to integrate light for the corresponding exposure duration. In some example embodiments, at least two of the corresponding exposure durations or at least two of the corresponding exposure start times are different in the image.

An image processing apparatus comprises a processing unit configured to provide an image containing a first object and a second object, with a lighting effect from a virtual light source, a setting unit configured to set a parameter of the virtual light source; and a designating unit configured to designate the first object and/or the second object, based on a user's operation, wherein, in a case in which the designating unit has designated at least one of the first object and the second object, the first object and the second object are provided with an effect of virtual light from a same direction, and in a case in which the designating means has not designated any object, the first object and the second object are provided with an effect of virtual light from different directions.

In some implementations, a service qualification system may receive, from a user device, a set of images that depict a window. The service qualification system may perform an image-based analysis of the set of images to determine a reflectivity score associated with the window. The reflectivity score may be indicative of a quality associated with a signal of the service being received through the window. The service qualification system may determine, based on the reflectivity score, a service qualification metric that is indicative of a capability of receiving the service within the unit. The service qualification system may perform an action associated with the service qualification metric.

The light source is configured to provide multiplexed illumination to an object in a plurality of color channels, the imaging unit is configured to capture a first image and a second image of the object in the plurality of color channels, and the control unit is configured to determine an estimated motion of pixels between the first image and the second image in a first color channel, and to generate a first motion compensated image by extrapolating the estimated motion of pixels between the first image and the second image to at least another one of the plurality of color channels.

There is provided a system for performing image motion compensation. The system comprises a light source configured to provide pulsed illumination to an object, an imaging unit configured to capture a plurality of images of the object including a first image, a second image, and a third image, and a control unit configured to: determine a first motion map indicating an estimated motion between at least a section in the first image and at least the corresponding section in the second image, determine a second motion map indicating an estimated motion between at least the section in the first image and at least a corresponding section in the third image, or an estimated motion between at least the corresponding section in the second image and at least a corresponding section in the third image, and generate an at least partially motion compensated image.

An imaging system includes a scattering assembly with a scattering medium positioned a first distance from an object to be imaged. The scattering medium includes a plurality of particles suspended in a suspension medium and at least one field source generating an electromagnetic field to manipulate an orientation, concentration, spatial distribution, and/or other properties of the plurality of particles. The imaging system further includes a detector including a plurality of detector elements positioned a second distance from the scattering medium and an image processing system configured to reconstruct an image of the object from an object image signal detected by the detector using object light scattered by the scattering medium and incident on the detector.

A device and method for phase imaging and element detection based on wavefront modulation are provided to overcome the disadvantages of an existing interferometry such as twin image elimination, limit resolution, under-sampling wavefront measurement, and multi-modal measurement. From the perspective of light field encoding, the accurate measurement to a complex amplitude of a light field to be measured is completely achieved by the iterative calculation, and at the same time, a twin image problem may be effectively eliminated, and it has the multi-modal (multi-wavelength) reconstruction ability. Theoretically, it is able to reach the diffraction limit resolution, may be widely used in phase imaging, optical element surface-type detection, polarization distribution measurement and the like, and it has a wide range of applications.

A multi-point measurement of a scene captured in an image frame may be used to process the image frame, such as by applying white balance corrections to the image frame. In some examples, the image frame may be segmented into portions that are illuminated by different illumination sources. Different portions of the image frame may be white balanced differently based on the color temperature of the illumination source for the corresponding portion. Infrared measurements of multiple points in the scene may be used to determine a characteristic of the illumination source of different portions of the scene. For example, a picture that includes indoor and outdoor portions may be illuminated by at least two illumination sources that produce different infrared measurements values. White balancing may be applied differently to these two portions to correct for color temperature of the different sources.
