A connection structure for a camera module with an auto-focus feature and a module connector that eliminates the need for wires and FPCs for connection between motor signal terminals and a printed circuit substrate, as well as the need for solder connection operations is also eliminated. A camera module with an auto-focus feature is equipped with a module base on which is disposed a camera signal contact terminal, and a main module unit on which is disposed a motor signal terminal extending from a side surface. A module connector includes an installation cavity for installing the camera module. A motor signal contact is disposed on the module connector, and the motor signal terminals are formed with a contact, which comes into contact with contacts of the motor signal contact when the camera module is installed in the installation cavity.
摘要:
An ultraviolet ray measuring method using an ultraviolet ray receiving element having a specific spectral sensitivity. The method includes: estimating an estimated value of an entire region from the spectral sensitivity of the ultraviolet ray receiving element and a solar spectral radiation spectrum; estimating an estimated value of a specific region from a specific action curve and the spectral sensitivity and the solar spectral radiation spectrum; and determining specific ultraviolet ray information by, on the basis of the estimated value of the entire region and the estimated value of the specific region, correcting an actually measured value which is measured by the ultraviolet ray receiving element. Further, specific ultraviolet information, which is obtained on the basis of sun altitude information, is also corrected.
