The invention discloses a piezoelectric energy collector applied to a road deceleration strip and a collection circuit of the piezoelectric energy collector, and aims at solving the technical problem of low collection efficiency of an existing piezoelectric energy collector. According to the technical scheme, an impact-type cantilever beam structure is adopted by the collector; when a vehicle drives on the deceleration strip, mechanical energy of the vehicle is converted into electric energy through a piezoelectric material in the collector; and after the vehicle drives off the deceleration strip, a cantilever beam is in a free vibration state with damping and the mechanical vibration is further converted into the electric energy by the piezoelectric material, so that continuous output of the electric energy is achieved. By the matched collection circuit, input impedance can be matched with the impedance of the piezoelectric material during the period of shock and the period of free vibration separately through controlling and changing the switching period and the duty ratio of a DC-DC switching converter, so that electric energy output by the piezoelectric material is maximized. Furthermore, when no electric energy is generated, a piezoelectric energy collection circuit enters a sleep mode with extremely low power consumption, so that the energy is saved and the collection efficiency of the collection system is significantly improved.

Even if a size of a read image is large, a code search process can be speeded up to enable immediate output of a decoding result. Each time a predetermined number of lines of image data is taken, a pre-processing circuit executes pre-processing on the image data and calculates a characteristic amount indicating the likelihood of the code for each area in the image data. A processor determines a code candidate area based on the acquired characteristic amount and executes a decoding process of the determined area to generate a decoding result.
