Patent ID: 8736751

Claim:
An apparatus to display an image, comprising: a base to support an object, the base including a base arm; an illumination system that includes a plurality of illuminators configured to selectively illuminate the object; a camera system coupled to the base arm, the camera system configured to: capture a plurality of images of the object, wherein each of the plurality of images is captured for the object at different illumination conditions, wherein the different illumination conditions are obtained by individual energization and de-energization of the plurality of illuminators and wherein each of the plurality of images corresponds to a different respective illumination condition of the object; determine a brightness value for each pixel for each of the plurality of images; compare the brightness value, of corresponding pixels that represent a common region of the object from each of the plurality of images, with a first threshold value; compare the brightness value, of corresponding pixels that represent the common region of the object from each of the plurality of images, with a second threshold value; average the brightness values of the corresponding pixels, if the brightness value of each corresponding pixel is between the first threshold value and the second threshold value, to obtain respective averaged brightness values of the corresponding pixels from each of the plurality of images; determine a representative pixel from the corresponding pixels from each of the plurality of the images, wherein determined representative pixels include the respective average brightness values if the brightness value of each corresponding pixel is between the first threshold value and the second threshold value; form an image from the determined representative pixels; and output the image; an illuminator control system configured to control the plurality of illuminators; and a focus control system configured to adjust a focus of the camera system.
