A drive signal generating unit generates an imaging synchronization signal and a drive signal based on the imaging clock. A display clock generating unit generates a display clock. A display synchronization signal generating unit generates a display synchronization signal based on the display clock. A phase comparing unit compares a phase of the imaging synchronization signal with a phase of the display clock, and controls oscillation of the display clock generating unit based on a result of the comparison.

摘要： Image-pickup sections and an image-communicating/processing section 138 are connected by a single bus. Following the output of the image data, an output-controlling section in one of the image-pickup sections outputs an image-data-ending pattern, which indicates the end of outputting the image data, to a bus. An ending-pattern-detecting section in another image-pickup section detects the image-data-ending pattern, and outputs an image-pickup-operation-starting signal. The another image-pickup section starts an image-pickup operation and output of the image data based on the image-pickup-operation-starting signal.

摘要： An image coding apparatus includes a distortion determining unit, a plurality of compression operating units, and a selecting unit. The distortion determining unit determines an amount of optical distortion of an image associated with a set of input image data. The plurality of compression operating units has different compression and coding characteristics from each other. Each of the plurality of compression operating units is configured to convert at least a part of the set of input image data into a corresponding set of compressed and coded data. The selecting unit selects one of the plurality of compression operating units with reference to the result of determination by the distortion determining unit.
