Abstract
In an image processing device such as an electronic camera having a detecting section which detects blurring of an image (movement of the image) picked up by an imaging element, a part of evaluation or calculation required for controls (AF, AE, AWB, etc.) is performed in parallel with the detection of the blurring of the image in order to speed up the controls. After completing the detection of the image blurring, an influence of the blurring is corrected to perform final calculation. In this case, an image area as a calculation object can be limited to raise a processing efficiency.

An image processing device comprising:
- a detection unit for detecting blurring of an image picked up with an imaging element;
- a simplified calculation unit for calculating an intermediate value of evaluation data of the picked-up image in parallel with a detecting operation of the detection unit;
- a memory for memorizing a calculation result of the simplified calculation unit;
- and
- a final calculation unit for calculating a final value of the evaluation data from the intermediate value of the evaluation data memorized in the memory based on the blurring detected with the detection unit after completion of the detection with the detection unit.
An image processing device comprising:
