Imaging device and image generation method

An imaging device comprising:

• a stage configured to place a subject;
• a detector including a plurality of linear pixels having linear light receiving surfaces extending in a first direction arranged in a second direction orthogonal to the first direction with equal intervals;
• an image formation optical member configured to form an image based on imaging light passing through the subject on a detection surface of the detector;
• and
• an image processor configured to reconstruct the image of the subject based on detection intensity of the imaging light,
• wherein the stage is scannable in a direction parallel to the first direction,
• the detector is configured to set a sampling interval equal to or less than half a time to scan a distance of a line length of the linear pixel by the stage, and outputs the detection intensity at each sampling interval, and
• the image processor is configured to:
• (i) determine that a detection intensity distribution indicating the detection intensity with respect to position coordinates of the stage is a convolution of an image intensity distribution on an extension line of the linear pixel and a window function;
• (ii) calculate the image intensity distribution for each linear pixel by deconvolution from the detection intensity distribution;
• and (iii) generate an image of the subject by disposing the image intensity distribution calculated in all the linear pixels in an arrangement direction of the linear pixels.
