Imaging control device, imaging control method, and imaging device for increasing resolution of an image
An imaging element of an imaging unit 24 divides the exit pupil of an imaging optical system 21 into a plurality of regions and generates a pixel signal for each region.

X-ray imaging apparatus
In an X-ray imaging apparatus (100), an image processor (5b) is configured to apply a super-resolution process to a first region (A1) in each of acquired images (Ia), the first region including a subject (S), and to increase a number of pixels according to an increase in resolution in the first region by application of the super-resolution process thereto by a simpler process than the super-resolution process with respect to a second region (A2) other than the first region in each of the acquired images.

In some examples, the disclosure describes a nano-position stage, an imaging device coupled to the nano-position stage, and a controller comprising instructions to: instruct the imaging device to capture a first image of a subject, instruct the nano-position stage to alter a position of the imaging device a distance based on a pixel size of the first image, instruct the imaging device to capture a second image of the subject at the altered position, and generate a third image of the subject utilizing the first image and the second image.
SYSTEMS AND METHODS OF IMAGE ACQUISITION
An imaging method which comprises, while a line of sight of a camera is maintained fixedly oriented towards a target, controlling the camera to acquire an image by a sensor located at a current position relative to the camera, sending a command to an actuator of the sensor, for inducing a motion of the sensor relative to the camera along at least one direction, from the current position to a new position, controlling the camera to acquire an image by each of the pixel bands of the sensor, wherein motion of the sensor is performed during a first period of time, and the sensor is retained stationary at the new position during a second period of time, wherein acquisition of the image is performed during a third period of time, wherein a majority of the third period of time is within the second period of time.
SUBPIXEL LINE SCANNING
Subpixel line scanning. A slide scanning device comprises a plurality of line sensors (112a, 112b, 112c), each comprising a plurality of pixel sensors. Each line sensor is offset from an adjacent line sensor by a fraction of a length of each pixel sensor, and generates a line image of the same field of view at its respective offset. For each of a plurality of positions on a sample, a processor combines the line images of the same field of view, generated by the plurality of line sensors at their respective offsets, to produce a plurality of subpixels for each of at least a subset of pixels within the line images of the same field of view, and generates an up-sampled line image of the position comprising the plurality of subpixels. Then, the processor combines the up-sampled line images of each of the plurality of positions on the sample into an image.

Multi-axis gimbal extended pixel resolution actuator
A multi-axis gimbal actuator includes a first tilt frame tiltably coupled to a second tilt frame. The second frame is tiltably coupled to a reference frame. The first tilt frame is offset from the second tilt frame and approximately parallel to the second tilt frame while in a neutral position. An optical element is mounted on the first tilt frame.
DETERMINING PIXEL INTENSITY VALUES IN IMAGING
In an embodiment, a method (100) is described. The method includes accessing (102) data from a sequence of images of a subject illuminated with ambient light and illumination having a sinusoidal intensity modulation in time. An imaging device is used to obtain the sequence of images and is configured such that a different spatial intensity modulation pattern is apparent in consecutive images of the sequence. The method further includes determining (104), based on a set of measured pixel intensity values in each of the sequence of images, a set of revised pixel intensity values for generating a revised image of the subject such that a reduced level of ambient lighting is apparent in the revised image compared with the level of ambient lighting apparent in at least one of the sequence of images.
IMAGE PROCESSING DEVICE AND METHOD, AND PROGRAM

When performing imaging while shifting the pixel phase of an image sensor having a two-dimensional pixel array, an image processing device adds up, for each pixel phase, a plurality of frames imaged in each pixel phase, and generates an addition frame for each pixel phase. The image processing device then combines the addition frames of the respective pixel phases. The present technology can be applied to a sensor shift imaging system.
