CAMERA CAPTURE [scale, [x , y]]
This captures a picture from the camera (RGB565) and displays it on an LCD screen.
An SPI LCD must be connected and enabled in order for the command to work. (ILI9341 and ST7789_320 recommended).
Scale defaults to 1 and x,y each to 0 By default a 160x120 image is output on the LCD with the top left at 0,0 on the LCD. Setting scale to 2 will fill a 320x240 display with the image.
Setting the x and y parameters will offset the top left of the image on the LCD. Update rate in a continuous loop is 7FPS onto the display at 1:1 scale and 5FPS scaled to 320x240.
Assuming the display has MISO wired it is then possible to save the image to disk using the SAVE IMAGE command.
