Abstract
An image signal processing method for storing a series of image signals, which are arrayed in the array sequence of scanning lines on an image, on a recording medium or transmitting the image signals to a receiving device, and reproducing the image from the stored or transmitted image signals comprises the steps of dividing the series of the image signals into predetermined units in the course of storing or transmitting the series of the image signals, and storing or transmitting the image signals by changing the sequence of the respective units so that the units which were adjacent to each other do not adjoin each other. The image is reproduced by rearranging the units in the original sequence in the course of image reproduction.
Claims3
An image signal processing method for storing a series of image signals on a recording medium and reproducing the image from the stored image signals, wherein the improvement comprises the steps of:
- (i) dividing said series of image signals into a plurality of predetermined units;
- (ii) storing the image signals by dividing said series of image signals into a plurality of blocks, and changing the sequence of respective units within each of said blocks so that predetermined units which were adjacent to each other do not adjoin each other;
- and
- (iii) reproducing the image by rearranging the predetermined units in the original sequence in the course of image reproduction.
An image signal processing method for storing a series of image signals on a recording medium and reproducing the image from the stored image signals, wherein the improvement comprises the steps of:
- (i) dividing said series of image signals into a plurality of predetermined units;
- (ii) storing the image signals by dividing said series of image signals into a plurality of blocks, and changing the sequence of respective units within each of said blocks so that predetermined units which were adjacent to each other do not adjoin each other;
- (iii) reproducing the image by rearranging the predetermined units in the original sequence in the course of image reproduction;
- and
- (iv) in the case where an image signal error arises in the course of storing said image signals, or in the course of reading said stored image signals, the image signal at the image signal portion where said error arose is inferred from the image signals in the vicinity of said image signal portion where said error arose and used for image reproduction in the course of image reproduction.
An image signal processing method for storing a series of image signals on a recording medium, and reproducing the image from the stored image signals, wherein the improvement comprises the steps of:
- (i) dividing said series of image signals into a plurality of predetermined units, wherein a unit size of said predetermined units is determined on a basis of a difference in a size of burst errors expected during storing and reproducing operations;
- (ii) storing the image signals by dividing said series of image signals into a plurality of blocks, and changing the sequence of respective units in each of said blocks so that predetermined units which were adjacent to each other do not adjoin each other;
- (iii) reproducing the image by rearranging the predetermined units in the original sequence in the course of image reproduction;
- and
- (iv) in the case where an image signal error arises in the course of storing said image signals, or in the course of reading said stored image signals, the image signal at the image signal portion where said error arose is inferred from the image signals in the vicinity of said image signal portion where said error arose and used for image reproduction in the course of image reproduction.
