| Abstract: | A method for micro-lens array focus measurement,which is based on image processing technology,is simply described.The method takes use of image processing technology to solve the problem of focus searching.Several definition appraising functions are presented and compared.From these functions,the most appropriate function is chosen to estimate the position of focus.It is testified that this method can satisfy the request of micro-lens array's focus measurement. |
