| 20090060388 | Image Processing Device, Image Processing Method, and Image Processing Program - An image processing device, which performs, on image data, image quality adjustment processing and resize processing to adjust an image size to a target size, and which outputs processed image data, including: an adjustment parameter creation unit which creates adjustment parameters for the image quality adjustment processing, on the basis of original image data; a contrast information creation unit which acquires the image size of the original image data and the target size, and creates size contrast information; a resize amount detection unit which determines the resize amount in the resize processing on the basis of the size contrast information; and an adjustment parameter modification unit which modifies the adjustment parameters in accordance with the resize amount. | 2009-03-05 |
| 20090060389 | IMAGE PROCESSING APPARATUS - From an image pickup element, pixel signals of Bayer array are outputted. A correlation calculation part calculates correlation values with respect to a specified pixel in vertical and horizontal directions. A first interpolation part performs a pixel interpolation process while evaluating the correlation highly. A second interpolation part performs a pixel interpolation process while evaluating the correlation relatively low. A complete signal of RGB outputted from the first interpolation part is converted into a luminance signal in a first color space conversion part, and a complete signal of RGB outputted from the second interpolation part is converted into a color difference signal in a second color space conversion part. | 2009-03-05 |
