Apparatus for arranging scan signal in a scanner having image detector arrayed linear

摘要

The scanning signal from the scanner alignment device having an image detecting element of a linear array is disclosed. Scanning signal alignment device from the scanner with an image detection element in a linear arrangement in accordance with the invention receives the scan control signal having control information for the scan signal and the analog scanning signal of the analog which is detected from the image detecting element with an external linear array indent, converting the scanning signal of the analog to digital, and accepts an addressed control signal in the first and second digital converted digital scan signal from the scan signal input, a scan signal input to 2 generates a select signal from the scan control signal, the first selection signal in response to a digital scanning signal, the first terminal or the second switch for switching output to a second terminal, the first response to a memory control signal to store the sorted digital scanning signal output to the first terminal or stored in the digital scanning signal to poison shipping is the second to the first line memory, a second memory in response to the control signal Shipping the digital scanning signal storage, or stored by sorting the digital scanning signal output to the terminal dock has a second line memory, the digital scan signal in response to a second selection signal which is read out from the first line memory or a second line memory to selectively respond to the selector, the data outputted from the selector output to the frame memory and addressing control signals to store frame by frame the digital scanning signal can be stored, is arranged on the first and the second line memory, the first and second It characterized in that it comprises a memory controller for generating a memory control signal, and may convert the two line memories, and the scan signal using a memory controller which is input to the non-alignment to form the scan signal in real-time alignment. Further, first and second, because the scan signal aligned to a line memory store, before stored in the frame memory can be performed, such as gain adjustment or offset adjustment required for pre-processing of the signal processing can be carried out effective signal processing have.
