Abstract
An array of light sensors is integrated with a circuit to control the selection of each light selector and to digitized the amplitude of the light impinging on each sensor. Each light sensor is addressable by an external microprocessor.
Claims26
An integrated multi-element sensor device, comprising:
- an array of light sensor elements for detecting light impinging thereon and for outputting a voltage representative of the impinging light intensity, each of the light sensing elements being individually addressable;
- a mode select circuit for activation of a select function to specify each light sensing element that is to be addressed;
- a controller circuit for selecting each light sensing element that is to be addressed;
- and
- an analog-to-digital converter for digitizing the amplitude of the output voltage of the selected light sensing element.
