So, what about you give more details, like the code, target device, clock rate, etc...?

thank you for your answer.
i attached my code. but just simple code for all 1's pixel count.
actually i want to count only linked 1's pixel count. but i can't.
=================================
library ieee;
library cycloneive;
use ieee.std_logic_1164.all;
use ieee.std_logic_unsigned.all;
use ieee.numeric_std.all;
use cycloneive.all;
entity img_processor is
port(
CLK10KHz : in std_logic;
line_scan_data : in std_logic_vector(4 downto 0);
qty_1_pixel : out std_logic_vector(7 downto 0)
)
end entity;
architecture rtl of img_processor is
type img_array is array(0 to 4) of std_logic_vector(4 downto 0);
signal img : img_array;
begin
process(CLK10KHz)
begin
if CLK10KHz'event and CLK10KHz = '1' then
img(0) <= line_scan_data;
for i in 0 to 3 loop
img(i+1) <= img(i);
end loop;
qty_1_pixel <= ((("0000000"&img( 0)(0) + img( 0)(1) + img( 0)(2)) + ("0000000"&img( 0)(3) + img( 0)(4)))
+ (( "0000000"&img( 1)(0) + img( 1)(1) + img( 1)(2)) + ("0000000"&img( 1)(3) + img( 1)(4)))
+ (( "0000000"&img( 2)(0) + img( 2)(1) + img( 2)(2)) + ("0000000"&img( 2)(3) + img( 2)(4))))
+ ((("0000000"&img( 3)(0) + img( 3)(1) + img( 3)(2)) + ("0000000"&img( 3)(3) + img( 3)(4)))
+ (( "0000000"&img( 4)(0) + img( 4)(1) + img( 4)(2)) + ("0000000"&img( 4)(3) + img( 4)(4))));
end process;
end rtl;
