Image processing apparatus and image processing method

摘要

An image processing apparatus includes an image processing command input section to receive image processing commands for image data written into a memory by units of one line, a line number deriving section to derive a number of lines of the image data required to execute image processing operations based on the image processing commands received by the image processing command input section, a line number indicating section to output a numerical value indicating the number of lines of the image data derived by the line number deriving section, a read timing controlling section to control read timing from the memory in response to the numerical value output from the line number indicating section, a parameter indicating section to output parameters used for the image processing operations, and an image processing section to execute the image processing operations.

1. An image processing apparatus comprising:
an image processing command input section configured to receive, as an input, one or more image processing commands for writing image data into a memory by units of one line; a storage section configured to store a table of line numbers in which at least one image processing operation is associated with a number of lines required for performing the at least one image processing operation; a line number deriving section configured to derive a maximum number of lines of the image data required to execute an image processing operation when the one or more image processing commands are received by the image processing command input section, the maximum number of lines being based on the one or more image processing commands received by the image processing command input section; a line number indicating section configured to output a numerical value indicating the number of lines of the image data derived by the line number deriving section; a read timing controlling section configured to control read timing from the memory in response to the numerical value output from the line number indicating section; a parameter indicating section configured to output parameters used for the image processing operations based on the image processing commands received by the image processing command input section; and an image processing section configured to execute the image processing operations in response to the parameters output from the parameter indicating section.
