Arduino Uno with Camera and LCD
No, this is not possible.

The camera outputs a JPEG image. To display that on the TFT screen it is necessary to decompress that JPEG image and send the raw 16-bit (RGB565) colour information to the screen.

The Arduino doesn't have enough memory to do the job.

I wrote an absolute minimal JPEG decompressor a while back. It uses the absolute minimum memory possible (it operates on one macroblock at a time), and still requires around 100KB. That's 50x more than the Arduino Uno has.

Also on a 200MHz, 32-bit chip with FPU it takes about a minute to decompress a 320x240 pixel image. I can't even begin to imagine how many days that would take on a little Arduino Uno even if it did have enough memory to do the job...

As has been suggested, you need a more powerful board. And if you're going that route you may as well drop the useless OV7670 and get a Raspberry Pi with a proper Pi Camera module (or at least a USB webcam).
