Abstract

An image processing device and method for reducing the line memory consumption in an image processor is disclosed. The image processing device includes an imaging unit for acquiring image data by imaging a subject, an image memory to which a first part out of first and second parts of the image data output from the imaging unit is input, and an image processor for image-processing the first part received from the image memory, image-processing the second part received without passing it through the image memory, and generating a processed image corresponding to the image data by synthesizing the processed first and second parts.

Claims

1. An image processing device comprising:

an imaging unit for acquiring image data by imaging a subject;

an image memory to which a first part out of first and second parts of the image data output from the imaging unit is input; and

an image processor for image-processing the first part received from the image memory, image-processing the second part received without passing through the image memory, and generating a processed image corresponding to the image data by synthesizing the processed first and second parts.

2. The image processing device of claim 1, further comprising a switching unit for switching an input of the first part to the image memory and an input of the second part to the image processor.

3. The image processing device of claim 2, wherein the image data includes a plurality of pieces of line data each having the first and second parts;

wherein the first and second parts of each piece of line data are divided in a same location in a line direction; and

wherein the switching unit selectively switches an input of the first part to the image memory and an input of the second part to the image processor on a line data basis.

4. The image processing device of claim 3, wherein the first and second parts have an overlapping part in which leading and subsequent pixels in the same location are included in the line direction.

5. The image processing device of claim 3, wherein the first part of each piece of line data, which is input to the image memory, is input to the image processor after being summed.

6. The image processing device of claim 1, wherein the first part is input from the image memory to the image processor after the second part is processed by the image processor.

7. An image processing method comprising:

inputting to an image memory a first part out of first and second parts of image data output from an imaging unit;

inputting the second part to an image processor without passing through the image memory and image-processing the second part;

inputting the first part from the image memory to the image processor and image-processing the first part; and

generating a processed image corresponding to the image data by synthesizing the processed first and second parts.

8. A non-transitory computer-readable recording medium having recorded thereon a computer program for executing an image processing method, the method comprising:

inputting to an image memory a first part out of first and second parts of image data output from an imaging unit;

inputting the second part to an image processor without passing through the image memory and image-processing the second part;

inputting the first part from the image memory to the image processor and image-processing the first part; and

generating a processed image corresponding to the image data by synthesizing the processed first and second parts.
