Abstract
A method for converting image data from serial to parallel is provided. The method has steps of: receiving serial data of an image into a line buffer according to a serial clock signal of the image, wherein the serial data at least comprises a frame start code, and a row start code; detecting the frame start code of the serial data in the line buffer to trigger a vertical synchronous signal of the image; and detecting the row start code of the serial data in the line buffer to trigger a horizontal synchronous signal of the image.

A method for converting image data from serial to parallel, comprising steps of:
- receiving serial data of an image into a line buffer according to a serial clock signal of the image, wherein the serial data at least comprises a frame start code, and a row start code;
- detecting the frame start code of the serial data in the line buffer to trigger a vertical synchronous signal of the image;
- and
- detecting the row start code of the serial data in the line buffer to trigger a horizontal synchronous signal of the image.
A method for converting image data from serial to parallel, comprising steps of:
- receiving serial data of an image into a line buffer according to a serial clock signal of the image, wherein the serial data at least comprises:
- a frame start code, for indicating that frame data of a frame of an image has started;
- a first row start code, following the frame start code, for indicating that the first row data of a first row of the frame of the image has started;
- a last row start code, for indicating that last row data of a last row of the frame of the image has started;
- and
- a frame end code, for indicating that the frame data of the frame of the image has ended;
- a first row end code, following the first row data and being followed by a second row start code, for indicating that the first row data of the first row of the frame of the image has ended;
- and
- a last row end code, being followed by the frame end code, for indicating that the last row data of the last row of the frame of the image has ended;
- detecting the frame start code of the serial data in the line buffer to trigger a vertical synchronous signal of the image;
- and
- detecting the row start code of the serial data in the line buffer to trigger a horizontal synchronous signal of the image.
An apparatus for converting image data from serial to parallel, comprising:
- a line buffer, for receiving serial data of an image-according to a serial clock signal of the image, wherein the serial data at least comprises a frame start code, and a row start code;
- and
- a code matching logic circuit, coupled to the line buffer, further comprising:
- a vertical synchronous signal generating unit for detecting the frame start code of the serial data in the line buffer to trigger a vertical synchronous signal of the image;
- and
- a horizontal synchronous signal generating unit for detecting the row start code of the serial data in the line buffer to trigger a horizontal synchronous signal of the image.
