Speckle imaging device, speckle imaging system, and speckle imaging method

Abstract

The present technology provides a speckle imaging device including: an irradiation condition setting unit that sets an irradiation condition for coherent light with which an imaging object is irradiated; an imaging unit that captures scattered light obtained from the imaging object irradiated with the coherent light; an image generation unit that generates a speckle-enhanced image from a captured image captured by the imaging unit; and a leveling processing unit that generates a leveled speckle image from speckle-enhanced images corresponding to two or more different irradiation conditions.

1 . An image processing system, comprising:
 an irradiation unit configured to irradiate an object with coherent light;   an imaging unit configured to capture at least two images of the object with different irradiation conditions;   an acquisition unit configured to acquire the captured at least two images;   a leveling processing unit configured to generate a leveled speckle image from the captured at least two images; and   an output unit configured to output the leveled speckle image.   
     
     
         2 . An image processing apparatus, comprising:
 an acquisition unit configured to acquire a plurality of images of an imaging object, wherein the plurality of images is captured based on at least two different irradiation conditions;   a leveling processing unit configured to generate a leveled speckle image from the plurality of images; and   an output unit configured to output the leveled speckle image.   
     
     
         3 . The image processing apparatus according to  claim 2 , wherein the irradiation conditions includes irradiation angles or irradiation positions. 
     
     
         4 . The image processing apparatus according to  claim 2 , wherein the imaging object includes fluid. 
     
     
         5 . The image processing apparatus according to  claim 4 , wherein the fluid is blood. 
     
     
         6 . The image processing apparatus according to  claim 2 , wherein the image processing apparatus is mounted on one of a surgical microscope or a surgical endoscope. 
     
     
         7 . The image processing apparatus according to  claim 2 , further comprising an analysis unit that analyzes a state of the imaging object based on the leveled speckle image. 
     
     
         8 . The image processing apparatus according to  claim 7 ,
 wherein the imaging object includes fluid, and   wherein a flow velocity of the fluid is analyzed in the analysis unit.   
     
     
         9 . The image processing apparatus according to  claim 2 , further comprising a light source unit that emits coherent light. 
     
     
         10 . An image processing method, comprising:
 in an information processing apparatus:   acquiring, by an acquisition unit, a plurality of images captured based on at least two different irradiation conditions;   generating, by a leveling processing unit, a leveled speckle image from the plurality of images; and   outputting, by an output unit, the leveled speckle image.   
     
     
         11 . A non-transitory computer-readable medium having stored thereon, computer-executable instructions, which when executed by an image processing apparatus, cause the image processing apparatus to execute operations, the operations comprising:
