Hi Lenin!
To convert the 16bpp 320x340 bitmap image to a single 1D array in RGB565 format, follow the steps:
- Extract the R, G and B components from the image.
R = A(:,:,1);
G = A(:,:,2);
B = A(:,:,3);
- Convert to RGB565 format to reduce the bit depth of each color component.
R5 = bitshift(uint16(R), -3); % converts the 8-bit red values to 5 bits.
G6 = bitshift(uint16(G), -2); % converts the 8-bit green values to 6 bits.
B5 = bitshift(uint16(B), -3); % converts the 8-bit blue values to 5 bits.
- Combine into a Single 16-bit Value.
RGB565 = bitshift(R5, 11) + bitshift(G6, 5) + B5;
% combines the R5, G6, and B5 components into a single 16-bit integer for each pixel.
- Convert to a 1D Array.
RGB565_1D = reshape(RGB565, 1, []); % Reshapes the 2D matrix of 16-bit values into a 1D array, which is suitable for use in C
disp(RGB565_1D(1:10)); % Displays the first ten values of the 1D array for verification purposes.

Hope this helps!
