Claims
- 1. An image processing apparatus comprising:
- a) inputting means for inputting image data;
- b) compression encoding means for compression encoding the image data input by said inputting means;
- c) memory means for storing the image data encoded by said compression encoding means;
- d) enlarging means for electrically enlarging an image size of the image data stored in said memory means; and
- e) control means for controlling an enlargement ratio of said enlarging means, said control means controlling a compression processing of said compression encoding means according to said enlargement ratio.
- 2. An apparatus according to claim 1, wherein said input means includes image pickup means for photographing an object image, thereby obtaining the image data.
- 3. An apparatus according to claim 2, further comprising recording means for recording the image data enlarged by said enlarging means on a recording medium.
- 4. An apparatus according to claim 1, further having display means for displaying the image enlarged by said enlarging means.
- 5. An apparatus according to claim 1, wherein said memory means extracts the image data the image data corresponding to a portion to be enlarged and stores the extracted partial image.
- 6. An image processing apparatus comprising:
- a) input means for inputting image data;
- b) enlarging means for electronically enlarging an image size of the image data input by said input means;
- c) encoding means for encoding the image data enlarged by said enlarging means, said encoding means including quantizing means for quantizing the image data; and
- d) control means for controlling an enlargement ratio of said enlarging means, said control means controlling a quantization step of said quantizing means according to said enlargement ratio.
- 7. An apparatus according to claim 6, wherein said encoding means includes converting means for converting the image data processed by said enlarging means into frequency component data and wherein said quantizing means quantizes the image data converted by said converting means.
- 8. An apparatus according to claim 6, further having multiplexing means for multiplexing the data encoded by said encoding means and quantization information regarding the quantization step which is controlled by said control means.
- 9. An apparatus according to claim 6, further having recording means for recording the data encoded by said encoding means onto a recording medium.
- 10. An apparatus according to claim 8, further having recording means for recording the data multiplexed by said multiplexing means onto the recording medium.
- 11. An apparatus according to claim 6, further having image pickup means for photographing an object image, thereby obtaining the image data.
- 12. An image processing apparatus comprising:

- 13. An apparatus according to claim 12, wherein said input means includes image pickup means for obtaining the image data.
- 14. An apparatus according to claim 12, further having recording means for recording the image data encoded by said compression encoding means onto a recording medium.
- 15. An apparatus according to claim 12, further having display means for displaying the image data enlarged by said enlarging means.
- 16. An image processing method comprising the steps of:
- inputting image data;
- compression encoding the input image data;
- storing the encoded image data in a memory;
- electrically enlarging an image size of the image data stored in said memory; and
- controlling an enlargement ratio of said enlarging step, said control step controlling a compression processing of said compression encoding step according to said enlargement ratio.
- 17. An image processing method comprising the steps of:
- inputting image data;
- electronically zooming the input image data;
- compression encoding the zoomed image data; and
- controlling a zoom magnification ratio of said electronic zooming step, said control step controlling a compression processing of said compression encoding step according to said zoom magnification ratio.
