#46225 - video picture problem |
i would like to know that if i use the CMOS sensor and the DSP controller and use 8051 to interface it,
the picture via the video putput is not sharp when i reset it and it occurs ocassionally. when the picture is ok, it is sharp, when it not ok, it will start with green color with picture and change color to normal color (i have adjust the color gain) but it is not sharp, when you put the hand before the cam,you will see the hand sharp but the sharpness is bad and you can see some floating point on the gap and you can see some green color on the edge, also, the second case, is it will from green color to sharpless and then being sharp and then normal,it also occurs ocassionally. the DSP controller have interrupt to 8051 and i have chase the program counter , but i found the P.C. is random but still have pattern, but because it chase the pc before the interrupt subroutine, but i think the PC is useless, because it is random, i have reset the CMOS sensor and it is useless, what is the reason behind that, ??? |
