Human body detecting device and an image processing apparatus of the human body detecting device

The present invention provides a human body detecting device and the like can be accurately determined approaching person. Which includes having a pair of positive and negative electrodes (10a), respectively, (10b), (20a), (20b) of the first and second pyroelectric sensor (10), (20) and the cover each pyroelectric sensor a lens (3). Formed in the detection region (6) consisting of a vertical plane perpendicular to the mounting surface is shaped (51) with a detection block (300, 301), wherein the detection block (300, 301) comprising a first pyroelectric thermal second positive field corresponding to the positive and negative electrodes and negative electrodes of the sensor corresponding to the first field of the positive electrode (100a) and a negative field (100B) and a second pyroelectric sensor of view (200a) and a negative field (200b), and the detection block (300, 301) coupled to the positive electrode of the first field and the field of view of the negative imaginary line (100c), or the extension, and a connecting second positive field and a negative imaginary line field of view ( forming 200c) intersect, or the extension, is perpendicular to the mounting surface 51, each of the virtual line is formed from the intersection of line symmetry relative to each other.
