Imaging device and control method
First Claim
1. An imaging device, comprising:
- a pixel configured to;
receive first light from a light source; and
convert the received first light to a current value of the pixel by photoelectric conversion; and
a detector configured to;
detect a change of the current value of the pixel;
detect an instruction trigger based on;
the change of the current value of the pixel, anda temporal change of the received first light of a same color and a same frequency from the light source,wherein the instruction trigger includes a first combination of changes of the current value of the pixel; and
issue an operation instruction based on the detected instruction trigger.

Abstract
The present disclosure relates to an imaging device and a control method that achieve low electric power consumption. A light source is of a wavelength received by an OPD pixel which is a pixel that detects light exposure, and its light emission is controlled by a PC or the like. The OPD pixel is a pixel specialized to detect a brightness of an imaging environment, and converts a received light amount to a current value, without electric power consumption, by utilizing photoelectric conversion. A detector detects a change (light intensity, light reception time, blinking pattern, etc.) of the current value of the OPD pixel, and upon detection, issues an operation instruction to another device (not depicted) or a solid state imaging device, by supplying a detection result to a control unit. The present disclosure can be applied to the solid state imaging device that includes the OPD pixel, for example.
