Abstract
An image processing apparatus has: a first image processing unit for generating first image data by executing a dodging processing to an image signal obtained by picking up an image of an object; and a second image processing unit for generating second image data by executing a dodging processing having a stronger effect thereof than that of the dodging processing by the first image processing unit to the image signal, wherein the first image processing unit repeats the dodging processing a plurality of times.
Claims14
An image processing apparatus comprising:
- an obtaining unit configured to obtain an image signal obtained by picking up an image of an object;
- a first image processing unit configured to generate first image data by executing a dodging processing to the image signal obtained by the obtaining unit, wherein the first image processing unit repeats the dodging processing a plurality of times;
- a second image processing unit configured to generate second image data by executing a dodging processing having a stronger effect thereof than the single dodging processing by the first image processing unit to the image signal obtained by the obtaining unit;
- and
- a low-pass filtering apply unit configured to perform a low-pass filtering processing in accordance with a number of repetition times of the dodging processing by the first image processing unit.

An image processing method comprising:
- an obtaining step of obtaining an image signal obtained by picking up an image of an object;
- a first image processing step of generating first image data by executing a dodging processing to the image signal obtained in the obtaining step, wherein in the first image processing step, the dodging processing is repeated a plurality of times;
- a second image processing step of generating second image data of an image compression method different from that of the first image data by executing a dodging processing having a stronger effect thereof than that of the single dodging processing in the first image processing step to the image signal obtained in the obtaining step;
- and
- a low-pass filtering apply step of performing a low-pass filtering processing in accordance with a number of repetition times of the dodging processing in the first image processing step.

An image processing apparatus comprising:
- an obtaining unit configured to obtain an image signal obtained by picking up an image of an object;
- a first image processing unit configured to generate first image data by executing a dodging processing to the image signal obtained by the obtaining unit, wherein the first image processing unit repeats the dodging processing a plurality of times;
- and
- a second image processing unit configured to generate second image data by executing a dodging processing having a stronger effect thereof than the single dodging processing by the first image processing unit to the image signal obtained by the obtaining unit, and
- wherein the first image data is moving image data and the second image data is still image data.

An image processing apparatus comprising:
- an obtaining unit configured to obtain an image signal obtained by picking up an image of an object;
- a first image processing unit configured to generate first image data by executing a dodging processing to the image signal obtained by the obtaining unit, wherein the first image processing unit repeats the dodging processing a plurality of times;
- a second image processing unit configured to generate second image data by executing a dodging processing having a stronger effect thereof than the single dodging processing by the first image processing unit;
- and
- a control unit configured to decrease a frame rate of the first image data when the dodging processing is performed a plurality of times by the first image processing unit.
2 more elements
An image processing apparatus comprising:
- an obtaining unit configured to obtain an image signal obtained by picking up an image of an object;
- a first image processing unit configured to process first image data by applying a gain to the image signal of low luminance, wherein the first image processing unit repeats the processing a plurality of times;
- a second image processing unit configured to process second image data by applying a gain to the image signal of low luminance, having a stronger effect thereof than the single processing by the first image processing unit;
- and
- a low-pass filtering apply unit configured to perform a low-pass filtering processing in accordance with a number of repetition times of the processing by the first image processing unit.
