<p>A white-balance colour temperature measurement device for an image pickup device, particularly, a white-balance colour temperature measurement device which is provided with a white or grey light penetrating sheet (2) and a colour temperature sensing element (21) in a lens light-source passage (4) or a machine body (11) of an image pickup device, such as a camera (1), a video camera, and a cellphone and a tablet personal computer which have a shooting function, wherein when focusing is conducted or a shutter is pressed in the process of shooting, outside light rays penetrate through the white or grey light penetrating sheet (2) to generate uniform neutral light rays to be transmitted onto the colour temperature sensing element (21); then, the colour temperature sensing element (21) directly sends a colour temperature signal of the sensed uniform neutral light rays into a main processor (12) of the camera (1), the video camera, the cellphone or the tablet personal computer; and the main processor (12) conducts balance and calculation processing on a chosen colour temperature value so as to obtain an accurate white-balance value, so that the colour of a shot photo or image achieves the purpose of greatly approaching to an on-site primary colour.</p> |
