A medical stereoscopic observation apparatus having circuitry that acquires a status signal according to a status of image processing from each image processing circuit of a plurality of image processing circuits that perform the image processing on input image data through a selected image processing unit among a plurality of image processing units in the respective image processing circuit and generates output image data to be output as a right eye image or a left eye image, and causes a second image processing circuit different from a first image processing circuit to switch the selected image processing unit to match the selected image processing unit of the first image processing circuit, according to the status signal acquired from the first image processing circuit among the image processing circuits of the plurality of image processing circuits.

Medical stereoscopic observation apparatus, medical stereoscopic observation method, and program

An imaging apparatus having a projector function which is advantageous in reducing size is provided. A light source of the imaging apparatus is constituted by three semiconductor lasers which respectively frontward emit lights of red, green and blue, each slit-shaped. To a GLV (Grating Light Valve) is applied a drive voltage as modulated by a projection image signal, so that the GLV diffracts the three lights emitted from the light source, with varying the amount or intensity of each light in accordance with the drive voltage or projection image signal. A scanning mirror is disposed between a taking lens and an image pickup device, so as to reflect the lights diffracted by the GLV toward the taking lens, with having each diffracted slit-shaped light scan in a direction.

Imaging apparatus

There are provided the delay coarse adjustment circuit , the delay fine adjustment circuit , and the inverter circuit . The delay coarse adjustment circuit stepwise varies a delay amount based on the delay coarse adjustment signal S and supplies the input oscillation signal S with a coarse delay. The delay fine adjustment circuit stepwise varies a delay amount based on the delay fine adjustment signal S and supplies the input oscillation signal S with a fine delay which is smaller than a delay amount supplied by the delay coarse adjustment circuit . The inverter circuit inputs the oscillation signal S from the delay coarse adjustment circuit or the delay fine adjustment circuit . The delay coarse adjustment circuit coarsely adjusts delays. The delay fine adjustment circuit fine adjusts delays. The coarse and fine adjustments provide a precision delay to generate the oscillation output signal S . The delay coarse adjustment circuit , the delay fine adjustment circuit , and the inverter circuit are connected in a ring for stepwise controlling an oscillation signal's oscillation frequency.
