Abstract
An imaging device receives from a host device image data and commands including a normal command, an image data command associated with a parameter indicative of a data length of the image data to be processed, and a real-time command to be processed prior to the normal command. The imaging device comprises a receiver configured to receive the image data command and subsequently the parameter from the host device; and a processor configured to process the parameter without processing the real-time command, even if a data sequence identical to a byte stream of the real-time command is included in the image data, after processing the image data command.
Claims4
An imaging device adapted to receive from a host device image data and commands including a normal command, an image data command associated with a parameter indicative of a data length of the image data to be processed, and a real-time command to be processed prior to the normal command, the imaging device comprising:
- a receiver configured to receive the image data command and subsequently the parameter from the host device;
- and
- a processor configured to process the parameter without processing the real-time command, even if a data sequence identical to a byte stream of the real-time command is included in the image data, after processing the image data command.
A method of controlling an imaging device adapted to receive from a host device image data and commands including a normal command, an image data command associated with a parameter indicative of a data length of the image to be processed, and a real-time command to be processed prior to the normal command, the method comprising:
- (a) receiving the image data command and subsequently the parameter from the host device;
- (b) after step (a), processing the image data command;
- and
- (c) after step (b), processing the parameter without processing the real-time command, even if a data sequence identical to a byte stream of the real-time command is included in the image data.
