[0072] figure 2 is a functional block diagram of an exemplary signal processing system including optical devices and signal processing devices. First, an overview of an optical device including a solid-state image pickup device will be described. According to the first embodiment, the optical device 2A includes a housing 21 . The housing 21 includes the solid-state image pickup device 1A and the lens unit 20 installed in the housing. The lens unit 20 is an example of an optical element. The lens unit 20 includes a single lens or a combination of a plurality of lenses.

[0073] The optical device 2A is configured such that the pixel unit 10A of the solid-state image pickup device 1A is set at the focal position of the lens unit 20 . An image of light incident through the lens unit 20 is focused on the pixel unit 10A of the solid-state image pickup device 1A.

[0074] In order to position the focal point of the lens unit 20 on the pixel unit 10A of the solid-state image pi...

Abstract

A solid-state image pickup device includes a pixel unit configured to convert light into an electrical signal, an A / D converter configured to convert a signal read from the pixel unit into a digital signal, a light modulation unit configured to modulate an externally input light beam using the signal digitized by the A / D converter and output a signal light beam based on the signal read from the pixel unit, a timing generation unit configured to generate a synchronization signal used for synchronizing input and output of signals of the pixel unit, the A / D converter, and the light modulation unit, and a controller configured to control readout of the signal.

Description

technical field [0001] The present invention relates to a solid-state image pickup device, an optical device including the solid-state image pickup device, a signal processing device connected to the optical device, and a signal processing system including the optical device and the signal processing device. Specifically, the present invention relates to a solid-state image pickup device, an optical device, a signal processing device, and a signal processing system capable of modulating an externally input light beam using pixel signals read from the solid-state image pickup device and outputting a modulated optical signal. Background technique [0002] As the processing speed and packing density of circuit boards increase, there arise problems of signal delay and occurrence of EMI (Electromagnetic Interference). Therefore, an optical interconnection technology that solves signal delay and signal degradation occurring in the electrical interconnection and electromagnetic int...
