| 20100149387 | Method and Apparatus for Imaging - According to one embodiment, a shading correction circuit, which corrects for the influence of ambient light quantity shading, for input image light from three CCD sensors of R, G and B, based on a distance from the center of a screen. A shading correction circuit does not make correction for a maximum correction area which is out of a circle with a distance a from the central part of a screen, and corrects for the influence of ambient light quantity shading for a minimum correction area with a distance b from the central part of a screen, after calculating a square L | 06-17-2010 |
| 20090136088 | IMAGE PROCESSING APPARATUS AND IMAGE FORMING APPARATUS - In a watermark process section in an image processing apparatus, a visible watermark pattern read-out section reads out a visible watermark pattern that is stored in a memory. An invisible watermark generating section draws an invisible watermark on the read-out visible watermark pattern. Image data, which includes both the visible watermark and drawn invisible watermark, is multiplied by an overlay ratio. An adder section adds the visible/invisible watermark image data, which is multiplied by the overlay ratio, and input image data. Thus, watermark-overlaid image data is generated. | 05-28-2009 |
