| 20080252765 | IMAGE PICKUP DEVICE - The present invention resides in an image pickup device capable of reducing the deformation of the image of the photographed object. An image pickup element included in the image pickup device has a matrix of pixels, for which the control of the charge storage and the readout of image signal data is performed on a row-by-row or column-by-column basis. The storage controller controls the charge storage operation of the image pickup element. On the other hand, the readout controller controls the readout of the image signal data from the image pickup element, while keeping constant the unit period for the readout of the image signal data from the image pickup element. A synchronization signal generator provides a synchronization signal as a timing reference for the frame-based operation of the image pickup element. The synchronization signal period controller variably controls the repetition period of the synchronization signal, while the photographing is under way. | 10-16-2008 |
| 20080273741 | Electronic Watermark Embedding Method, Electronic Watermark Detecting Method, Electronic Watermark Detecting Apparatus and Program - An electronic image into which an electronic watermark is to be embedded is divided into a plurality of image regions spatially, and pixels each having a property of being difficult to visually recognize a variation in a pixel value are extracted as adaptive pixels from each of the plurality of image regions. A variation between the pixel values of the adaptive pixels in one of the plurality of image regions and those of the adaptive pixels in an adjacent one of the plurality of image regions is produced, and the pixel values of the adaptive pixels of the plurality of image regions are varied in a time direction according to the value of an embedded bit set of the electronic watermark. An electronic-watermark-embedded image is then generated by making the variation in the pixel values of the adaptive pixels vary step by step at a boundary between the two of the plurality of image regions and/or in the time direction so that the variation makes a slow transition. | 11-06-2008 |
