Camera Module Reference

Complete API reference for camera capture and vision components.

EstuaryCamera (Example)

Example component for handling camera capture on Spectacles hardware. Listens for cameraCaptureRequest events and captures images automatically.

Location: Examples/EstuaryCamera.ts

Example Component

EstuaryCamera is an example implementation provided in the SDK's Examples/ folder. Copy it to your project and customize as needed.

Inspector Inputs

Input	Type	Default	Description
`debugMode`	`boolean`	`true`	Enable debug logging
`captureResolution`	`number`	`512`	Image resolution (smaller dimension in px)
`enableVisionAcknowledgment`	`boolean`	`true`	AI says acknowledgment before analyzing

Methods

Method	Parameters	Returns	Description
`manualCapture()`	`text?: string`	`void`	Manually trigger camera capture

Lifecycle

// CameraModule APIs cannot be called in onAwake!
// Component automatically initializes in OnStartEvent

Example Usage

@component
export class CameraController extends BaseScriptComponent {
    
    @input
    estuaryCamera: ScriptComponent;
    
    onAwake() {
        // Set up a tap to capture
        this.createEvent("TapEvent").bind(() => {
            (this.estuaryCamera as any).manualCapture("What is this?");
        });
    }
}

CameraCaptureRequest

Request object sent by the server when the AI agent decides it needs visual context. The server's LLM uses function calling to trigger camera captures — no client-side intent detection is needed.

Location: src/Core/EstuaryEvents.ts

import { CameraCaptureRequest } from 'estuary-lens-studio-sdk';

Interface

interface CameraCaptureRequest {
    request_id: string;   // Unique identifier for this request
    text?: string;        // Optional text context for the capture
}

Usage

import { EstuaryManager, CameraCaptureRequest } from 'estuary-lens-studio-sdk';

// Receiving camera capture requests from the server
EstuaryManager.instance.on('cameraCaptureRequest', (request: CameraCaptureRequest) => {
    print(`Capture requested: ${request.request_id}`);
    print(`Context: ${request.text}`);
});

EstuaryManager Camera Methods

Camera-related methods on the EstuaryManager singleton.

Location: src/Components/EstuaryManager.ts

sendCameraImage

Send a captured image to the server for AI analysis.

sendCameraImage(
    imageBase64: string,
    mimeType?: string,
    requestId?: string,
    text?: string,
    sampleRate?: number
): void

Parameter	Type	Default	Description
`imageBase64`	`string`	required	Base64-encoded image data
`mimeType`	`string`	`'image/jpeg'`	MIME type of the image
`requestId`	`string`	-	Request ID if responding to a `cameraCaptureRequest`
`text`	`string`	-	Text context to send with image
`sampleRate`	`number`	-	TTS output sample rate

import { EstuaryManager } from 'estuary-lens-studio-sdk';

EstuaryManager.instance.sendCameraImage(
    base64ImageData,
    'image/jpeg',
    'request-123',
    'What do you see?'
);

Events

cameraCaptureRequest

Emitted by both EstuaryManager and EstuaryCharacter when the server's AI agent requests a camera capture.

import { EstuaryManager, CameraCaptureRequest } from 'estuary-lens-studio-sdk';

// Via EstuaryManager
EstuaryManager.instance.on('cameraCaptureRequest', (request: CameraCaptureRequest) => {
    print(`Server requested capture: ${request.request_id}`);
});

// Via EstuaryCharacter
character.on('cameraCaptureRequest', (request: CameraCaptureRequest) => {
    print(`Server requested capture: ${request.request_id}`);
    // Capture and send image
    const imageBase64 = captureImage();
    EstuaryManager.instance.sendCameraImage(imageBase64, 'image/jpeg', request.request_id);
});
