Abstract: There is provided an information processing apparatus including a control unit that controls display on the basis of a detection value indicating a focus state of a lens acquired from a stereoscopic imaging unit, and a captured image signal for a left eye and a captured image signal for a right eye acquired from the imaging unit.

Abstract: The present disclosure relates to a control device and method, a program, and an endoscope system that are designed to be capable of shortening of the time before focusing. A target point distance calculation unit acquires an illumination intensity from an AE control unit, acquires a target point luminance value from a target point determination unit, and acquires an object reflectance from a reflectance holding unit. The target point distance calculation unit calculates (predicts) the distance to a target point, using the illumination intensity acquired from the AE control unit, the target point luminance value acquired from the target point determination unit, and the object reflectance acquired from the reflectance holding unit. Upon receipt of the target point distance from the target point distance calculation unit, the AF control unit searches for the focus position, using the received target point distance as the initial value.

Abstract: [Object] To provide an information processing apparatus, an information processing method, a program, and an information processing system. [Solution] An information processing apparatus including: a control unit configured to control display on the basis of a detection value indicating a focus state of a lens acquired from a stereoscopic imaging unit, and a captured image signal for a left eye and a captured image signal for a right eye acquired from the imaging unit.

Abstract: A detecting unit generates defference data between optical black level of digital input data and a predetermined black level and generates .gamma. characteristics selection signal. An offset signal obtained from the difference is added to the input data by an adding circuit. A .gamma. characteristics setting unit is supplied with the difference data and the output signal of the adding circuit and outputs a signal in which a white level, black level and .gamma. characteristics are corrected.
