FIELD: textiles, paper.
SUBSTANCE: projection device has a bell-shaped stand made of semi translucent rigid plastic, connected to the photocamera by the rigid connection, providing constant mutual position and parallelism of the support pad of the lens stand and the sensing matrix of the photocamera.
EFFECT: enhanced functionality, increased efficiency of obtaining images of textile materials, increased efficiency and accuracy of positioning the photocamera, reduction and stabilisation of luminance variance and geometric distortions of the images obtained, and providing the independence of brightness of the images obtained on the external lighting conditions.
