Here is the solution but don't forget to change condition according your requirement.

<?php

require_once '../app/Mage.php';
Mage::app('admin');

CapturePayment::createInvoice();

class CapturePayment {

    public static function createInvoice() {


        $orders = Mage::getModel('sales/order')->getCollection()
                        ->addFieldToFilter('status', array('processing'));

        foreach ($orders as $order) {
            $orderId = $order->getIncrementId();

            try {

                if (!$order->getId() || !$order->canInvoice()) {
                    echo 'Invoice is not allowed for order=>.' . $orderId . "\n";
                    continue;
                }
                $items = $order->getAllItems();
                $partial = false;
                $qtys = array();

                foreach ($items as $item) {
                    /* Check wheter we can create invoice for this item or not */
                    if (!CapturePayment::canInvoiceItem($item, array())) {
                        continue;
                    }
                    /* Get product id on the basis of order item id */
                    $productId = $item->getProductId();
                    /* If product is tablet then don't create invoice for the same */
                    /* Put your condition here for items you want to create the invoice e.g.*/
                    /* Load the product to get the release date */
                    $productDetails = Mage::getModel('catalog/product')->load($productId);

                    /* create your $qtys array here like */
                    $qtys['orderItemId'] = 'quantityOrdered'; 
                    /* NOTE: But if you don't want to craete invoice for any particular item then pass the '0' quantity for that item and set the value for $partial = true if some product remain in any order*/
                }
                /* Prepare the invoice to capture/create the invoice */
                $invoice = Mage::getModel('sales/service_order', $order)->prepareInvoice($qtys);

                if (!$invoice->getTotalQty()) {
                    continue;
                }

                $amount = $invoice->getGrandTotal();
