## Abstract

Provided is a digital image signal processing method, a recording medium for recording the method, and a digital image signal processing apparatus, in which a storage area of a memory may be efficiently used and an image desired by a user can be stored even when the storage area of the memory is insufficient. According to the present invention, a scene of an image may be recognized and a resolution and an image quality may be modified according to the recognized scene, thereby efficiently using the storage area of the memory.

## Claims

### Claim 1

A digital image signal processing method comprising:
recognizing, with a processor, a scene of an image;
determining, with the processor, a resolution and an image quality corresponding to the recognized scene; and
resizing and compressing the image with the determined resolution and the determined image quality.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
measuring a storage area of a memory; and
comparing the storage area of the memory with a reference,
wherein, if the storage area of the memory is smaller than the reference, a resolution and an image quality corresponding to the recognized scene are determined.

### Claim at position 3

3-4. (canceled)

### Claim 5 (depends on 1)

The method of claim 1, further comprising generating a database including resolutions and image qualities according to scenes.

### Claim 6 (depends on 5)

The method of claim 5, wherein the database is generated according to an input of a user.

### Claim 7 (depends on 1)

The method of claim 1, wherein the determining a resolution and an image quality corresponding to the recognized scene comprises:
deducing a priority of the resolution and a priority of the image quality corresponding to the recognized scene; and
determining a resolution and an image quality corresponding to the deduced priority of the resolution and the deduced priority of the image quality.

### Claim 8 (depends on 1)

The method of claim 1, further comprising, if compressing the image with the determined resolution and the determined image quality:
calculating an available number of images that can be stored in the storage area of the memory; and
displaying the available number of images.

### Claim 9 (depends on 7)

The method of claim 7, further comprising, if compressing the image with the determined resolution and the determined image quality:
calculating an available number of images that can be stored in the storage area of the memory in which the images can be stored;
displaying the available number of images;
determining whether to compress the image;
if the image is not to be compressed, adjusting at least one of the group consisting of the priority of the resolution and the priority of the image quality to a next priority; and
deducing a resolution and an image quality corresponding to the adjusted priority of the resolution or the image quality.

### Claim 10 (depends on 1)

The method of claim 1, wherein the scene is one selected from the group consisting of a frame guide scene, a night view scene, a portrait scene, a landscape scene, a macro scene, and a white scene.

### Claim 11 (depends on 10)

The method of claim 10, wherein a resolution of the landscape scene is greater than a resolution of the portrait scene.

### Claim 12

A computer readable recording medium having embodied thereon a program for executing, with a processor, a method comprising:
recognizing, with a processor, a scene of an image;
determining, with the processor, a resolution and an image quality corresponding to the recognized scene; and
resizing and compressing the image with the determined resolution and the determined image quality.

### Claim 13

A digital image signal processing apparatus comprising:
a scene recognition unit that recognizes a scene of an image;
a database that includes resolutions and image qualities according to scenes;
a resolution and image quality determining unit that determines a resolution and an image quality corresponding to the recognized scene by deduction from the database;
a scaler that resizes the image to have the determined resolution; and
a compression unit that compresses the image to have the determined image quality.

### Claim 14 (depends on 13)

The digital image signal processing apparatus of claim 13, wherein the scaler comprises a plurality of scalers for resizing the image with different sizes, and
the compressing unit comprises a plurality of compression units that apply different compression rates to the image so as to have different image qualities.

### Claim 15 (depends on 13)

The digital image signal processing apparatus of claim 13, further comprising:
a memory that stores an image file including the image;
a measuring unit that measures a storage area of the memory;
a comparing unit that compares the storage area of the memory with a reference; and
a control unit that controls such that if the storage area of the memory is smaller than the reference, the resolution and image quality determining unit determines a resolution and an image quality of the image.

### Claim 16 (depends on 13)

The digital image signal processing apparatus of claim 13, further comprising:
a memory that stores an image file including the image; and
a restoring unit that restores the image file to deduce the image.

### Claim 17 (depends on 13)

The digital image signal processing apparatus of claim 13, further comprising an imaging device for inputting the image.

### Claim 18 (depends on 13)

The digital image signal processing apparatus of claim 13, wherein:
the database comprises:
a first database including priorities of resolutions and image qualities according to scenes; and
a second database including resolutions corresponding to the priorities of the resolutions and image qualities corresponding to priorities of the image qualities;
and wherein:
the resolution and image quality determining unit deduces:
from the first database, the priorities of the resolutions and the priorities of the image qualities according to scenes; and
from the second database, the resolutions according to the priorities of the resolutions and the image qualities according to the priorities of the image qualities.

### Claim 19 (depends on 18)

The digital image signal processing apparatus of claim 18, further comprising, when compressing the image with the determined resolution and the determined image quality:
a calculation unit that calculates an available number of images that can be stored in a remaining storage area of a memory;
a display unit that displays the available number of images;
a determining unit that determines whether to compress the image; and
an adjusting unit that adjusts at least one of the group consisting of the priority of the resolution and the priority of the image quality to a next background priority, if the image is not to be compressed,
wherein the resolution and image quality determining unit deduces a resolution and an image quality corresponding to the adjusted priority of the resolution or the image quality.

### Claim 20 (depends on 13)

The digital image signal processing apparatus of claim 13, wherein the database comprises a resolution of a landscape scene that is greater than a resolution of a portrait scene.

### Claim 21 (depends on 13)
