Sure, it would be something like this:

local function isInView( obj, player )
   local xMin = player.x - fullw/2
   local xMax = player.x + fullw/2
   local yMin = player.y - fullh/2
   local yMax = player.y + fullh/2

   if( obj.x > xMax ) then return false end
   if( obj.x < xMin ) then return false end
   if( obj.y > yMax ) then return false end
   if( obj.y < yMin ) then return false end

   return true
end

   if( obj.x > xMax ) then return false end
   if( obj.x < xMin ) then return false end
   if( obj.y > yMax ) then return false end
   if( obj.y < yMin ) then return false end

   return true
end
