Abstract
A picture to be reproduced and displayed on a television monitor (10) is discerned as a plurality of partitioned areas in correspondence to keys labeled “1” to “9” disposed on a remote control unit (R). After having zoomed in a picture in a partitioned center area by operating a zoom key disposed on the remote control unit, a partial picture in a partitioned area corresponding to a given one of the keys “1” to “9” is zoomed in with a desired magnification factor in response to operation of the given key. Position of the zoomed-in partial picture on a full screen and the magnification factor thereof can be visually recognized by displaying cursors correspondingly.
Claims27
A picture apparatus for reading out first picture data from a recording medium and processing the first picture data to thereby derive second picture data for generating a zoomed-in picture on a screen by magnifying a partial area of a pre-zoom picture based on the first picture data, said picture apparatus comprising:
- a picture data processor dividing the pre-zoom picture into a total of M×N (where M and N are integers) partial areas indicative of selectable zoom-in areas;
- a plurality of M×N zoom-in area designating keys disposed at least on either one of a main body of said picture apparatus or a remote control unit;
- and
- a storage storing correspondence relations between said plurality of M×N zoom-in area designating keys and said M×N partial areas of the pre-zoom picture of the screen;
- wherein said picture data processor generating the second picture data corresponding to an operated one of said zoom-in area designating keys, and
- wherein relative locations of said plurality of M×N zoom-in area designating keys with respect to one another substantially correspond to relative locations of the M×N partial areas with respect to one another of the pre-zoom picture on the screen.
For a picture apparatus for reading out first picture data from a recording medium and processing said first picture data to thereby derive a zoomed-in picture on a screen by magnifying a partial area of a pre-zoom picture, a zoom processing method comprising:
- dividing the pre-zoom picture into a total of M×N (where M and N are integers) partial areas indicative of selectable zoom-in areas;
- storing correspondence relations between a plurality of M×N zoom-in area designating keys and said M×N partial areas of the pre-zoom picture of the screen, where the plurality of M×N zoom-in area designating keys are on at least either one of a main body of said picture apparatus or a remote control unit;
- and
- generating the zoomed-in picture corresponding to an operated one of said M×N zoom-in area designating keys;
- wherein relative locations of said plurality of M×N zoom-in area designating keys with respect to one another substantially correspond to relative locations of the M×N partial areas with respect to one another of the pre-zoom picture on the screen.
A computer program product comprising a computer usable medium having computer executable instructions to perform, for a picture apparatus for reading out first picture data from a recording medium and processing said first picture data to thereby derive a zoomed-in picture on a screen by magnifying a partial area of a pre-zoom picture, a zoom processing method, said program product:
- dividing the pre-zoom picture into a total of M×N (where M and N are integers) partial areas indicative of selectable zoom-in areas;
- storing correspondence relations between a plurality of M×N zoom-in area designating keys and said M×N partial areas of the pre-zoom picture of the screen, where the plurality of M×N zoom-in area designating keys are on at least either one of a main body of said picture apparatus or a remote control unit;
- and
- generating the zoomed-in picture corresponding to an operated one of said M×N zoom-in area designating keys;
- wherein relative locations of said plurality of M×N zoom-in area designating keys with respect to one another substantially correspond to relative locations of the M×N partial areas with respect to one another of the pre-zoom picture on the screen.
