Abstract
An image processing apparatus of the present invention provides an image reader which reads image, an image memory which stores image data read by said image reader, a compressor which reads out image data previously stored in said image memory, and compresses image data reading out, and a controller which controls starting operation of said compressor so as not to complete compressing image data in said image memory before completion of storing image data into said image memory.
Claims20
An image processing apparatus comprising:
- an image reader which reads image data of an image;
- an image memory which stores the image data read by said image reader;
- a compressor which receives the image data from said image memory, and performs a compression process whereby it compresses the image data;
- and
- a controller which controls a start timing of the compression process such that said compressor begins compressing the image data while said image reader is reading the image data, but does not complete compression of the image data stored in said image memory before said image reader completes reading the image data and a last of the image data is stored into said image memory.
An image processing apparatus comprising:
- an image reader which sequentially reads first image data of a first document and a second image data of a second document;
- an image memory which stores the first and second image data read by said image reader;
- a compressor which sequentially receives the first and second image data from said image memory, and performs a compression process whereby it compresses the first and second image data;
- and
- a controller which controls a start timing of an operation of said image reader such that said image memory begins storing the second image data before said compressor completes compression of the first image data, but does not complete storing the second image data before said compressor completes compression of the first image data.
A method for processing an image comprising the steps of:
- (a) reading image data of the image by an image reader and storing the image data in an image memory;
- (b) reading the image data from the image memory and compressing the image data read from the image memory;
- and
- (c) controlling a start timing of compressing the image data so that compressing the image data begins while the image reader is reading the image data, but is not completed before the image reader completes reading the image data and a last of the image data is stored into the image memory, to prevent the process of compressing the image data from overtaking the process of storing image data.
A method for processing first and second images comprising the steps of:
- (a) sequentially reading first image data of the first image and second image data of the second image and storing the first and second image data in an image memory;
- (b) sequentially reading the first and second image data from the image memory and compressing the first and second image data read from the image memory;
- and
- (c) controlling a start timing of steps (a) and (b) so that the image memory begins storing the second image data before completion of compressing the first image data, but storing the second image data is not completed before completion of compressing the first image data, to prevent the operation of storing the second image data from overtaking the compression of the first image data.
An image processing apparatus comprising:
- an image memory that stores image data sent from an image inputting section;
- a compressor that receives the image data from the image memory, and performs a compression process on the image data, wherein a compression rate of the compressor varies depending on the image data;
- and
- a controller that controls a start timing of the compression process by the compressor such that the compression process on the image data begins while the image memory is storing the image data from the image inputting section, but is not completed before a last of the image data is sent from the image inputting section to the image memory for storing, irrespective of the compression rate.
