We demonstrate new opportunities for the detection of concealed objects and of clothes components due to using of computer processing of images captured by passive THz cameras, manufactured by various companies. Computer processing of images results in a temperature resolution enhancing of cameras. We achieve good quality of the image due to applying various spatial filters to show independence of processed images on math operations. This result demonstrates a validity of observable objects. We discuss also a possibility of temperature trace observing on human skin if there is a difference in temperature inside the body. We consider images produced by THz passive cameras manufactured by Microsemi Corp., and ThruVision Corp., and Capital Normal University (Beijing, China).
