Systems and methods are provided for displaying images captured from a panoramic capsule camera system. The imaging unit includes a first optical element group having at least one first optical element, which contributes to the imaging. When the myocardium is penetrated by the tubes, advancement into the heart and penetration into the left ventricle by the pressure sensing tube results in a pressure increase that indicates to the physician that the drug delivery tube, by its placement relative to the pressure sensing tube is still in the myocardium and, thus, prepared to deliver the drug. Therefore, a code for artificially performing a fine adjustment of a reference voltage can be individually supplied for each chip.
