Abstract
An electronic stereoscopic imaging system having right and left image pick-up devices and right and left image data memories has a memory control module that is adapted to shift read start addresses of the right and left memories for horizontal pixel lines of right and left solid state image sensors to lower and higher addresses, respectively, according to object distances detected or visually determined so as thereby to vary a convergence angle of the right and left image pick-up devices with respect to the object according to the object distances apparently similar to a specified convergence angle suitable for natural stereoscopic vision.
Claims6
An electronic stereoscopic imaging system comprising:
- a pair of right and left image pick-up means for gathering right and left optical images of an object and converting said right and left optical images into right and left image signals, respectively, each said image pickup means comprising an objective lens system and a solid state image sensor;
- a pair of right and left memory means for storing said right and left image signals at addresses specified correspondingly to pixels of said solid state image sensors of said right and left image pick-up means, respectively;
- memory control means for controlling read of said right and left image signals out of said right and left memory means, respectively, for one frame;
- video signal processing means for performing processing of said right and left image signals read out of said right and left memory means, respectively necessary for color video images and alternately providing said right and left image signals to a monitor which displays alternating right and left video images corresponding to said right and left image signals, respectively;
- and
- wherein said control means shifts read start addresses of said right and left memory means for horizontal pixel lines of said right and left solid state image sensors to lower and higher addresses, respectively, according to distances of said object from said right and left image pick-up means so as thereby to vary a convergence angle of said right and left image pick-up means with respect to said object according to said distances apparently similar to a specified convergence angle suitable for natural stereoscopic vision.
