US 8,630,499 B2 · Image processing apparatus and control method thereof

Abstract

When an image processing apparatus capable of connecting to a digital camera is to perform image-correction processing on irreversible-compression encoded image data acquired from the digital camera, it is determined whether the image-correction processing can be executed by the connected digital camera. When the processing can be executed, it is confirmed whether or not RAW data that corresponds to the irreversible-compression encoded image data is present in the digital camera. If the corresponding RAW data is present in the digital camera, the digital camera is requested to execute the image-correction processing based on the RAW data. This makes it possible to suppress degradation in the image quality more than when directly correcting an irreversible-compression encoded image.

Dependent claims

An image processing apparatus, comprising:

an interface that communicates with a camera;
an acquisition unit that acquires compressed image data which is obtained by compressing image data photographed by the camera from the camera via the interface;
a decompressing unit that decompresses the compressed image data acquired by the acquisition unit;
an image correction unit for performing image-correction processing according to a parameter set by a user, on the image data decompressed by the decompressing unit;
and
a control unit that controls the acquisition unit and the image correction unit in accordance with a compression rate of the compressed image data acquired by the acquisition unit,
wherein the control unit controls the acquisition unit to further acquire compressed corrected image data on which the image-correction processing has been performed by the camera from the camera in the case where:
(a) the compression rate of the compressed image data acquired by the acquisition unit is larger than a threshold value and
(b) corresponding image data, which is not compressed and corresponds to the compressed image data of which the compression rate is larger than the threshold value, exists in the camera, and
wherein the control unit further controls the image correction unit to perform the image-correction processing on the decompressed image data decompressed by the decompressing unit in the case where the compression rate of the compressed image data acquired by the acquisition unit is smaller than the threshold value.

7 more elements

An image processing apparatus comprising:

an acquisition unit that acquires compressed image data obtained by compressing first image data;
a decompressing unit that decompresses the compressed image data acquired by the acquisition unit;
an image processing unit for performing image processing on the image data decompressed by the decompressing unit according to a set parameter;
and
a control unit that executes control in accordance with a compression rate of the compressed image data acquired by the acquisition unit,
wherein if the compression rate of the compressed image data acquired by the acquisition unit is larger than a threshold value, the control unit controls the acquisition unit to acquire, from an external apparatus, compressed processed image data obtained by the external apparatus by performing the image processing on the first image data according to the set parameter.
