How to use the @zxing/library.HybridBinarizer function in @zxing/library

private decode(
        callbackFn: (result: Result) => any,
        retryIfNotFound: boolean = true,
        retryIfChecksumOrFormatError: boolean = true,
        once = false
    ): void {

        if (undefined === this.canvasElementContext) {
            this.prepareCaptureCanvas();
        }

        this.canvasElementContext.drawImage(this.videoElement || this.imageElement, 0, 0);

        // @note generates zone.js error when switching cameras
        const luminanceSource = new HTMLCanvasElementLuminanceSource(this.canvasElement);
        const binaryBitmap = new BinaryBitmap(new HybridBinarizer(luminanceSource));

        try {
            const result = this.readerDecode(binaryBitmap);

            callbackFn(result);

            if (!once && !!this.stream) {
                setTimeout(() => this.decodeWithDelay(callbackFn), this.timeBetweenScansMillis);
            }
        } catch (re) {

            console.log(retryIfChecksumOrFormatError, re);

            if (retryIfNotFound && Exception.isOfType(re, Exception.NotFoundException)) {
                console.warn('Not found, trying again...');
