Abstract
A scanning circuit having rearranged circuit modules at each end of a flat cable. After the rearrangement, the flat cable carries scanning control signals produced by a conventional IC communication interface instead of timing signals and carries digital image data instead of easily distorted and interfered analog image signals.
Claims20
An optical scanning apparatus, comprising:
- communication means for receiving scan control signals from a main circuit module;
- and
- means for generating timing control signals for extracting an analog image signal in response to the received scan control signals, wherein the timing control signals are generated at an optical sensor circuit coupled to the main circuit module via the communication means, and wherein the received scan control signals do not comprise any timing control signals.
An apparatus, comprising:
- a main circuit module;
- a connection cable;
- and
- an optical sensor circuit module coupled to the main circuit module through the connection cable, wherein the optical sensor circuit module is configured to:
- receive scan control signals from the main circuit module;
- and
- generate timing control signals for extracting an analog image signal in response to the received scan control signals, wherein the received scan control signals do not comprise any timing control signals.
