DCAM-API, which is provided as driver software, supports all Hamamatsu digital cameras, and is designed to absorb the difference in their properties and to allow control by a common calling method. Please refer to Hamamatsu software information page at the link below.




For the latest detailed information such as compatible OS, I/F card and application software, please contact your local sales representative.


The SDK is a Software Development Kit for the integration of Hamamatsu cameras with the customer software. You may develop your own application software depends on the needs, for camera control with the DCAM-SDK and for recording DCIMG files with the DCIMG-SDK. DCAM-SDK and DCIMG-SDK can be downloaded from the link below after completion of user registration.

"Dark signal non-uniformity” (DSNU) describes pixel non-uniformities under dark conditions that are independent of read noise. 

Dark current

Currents that are thermally generated even in the dark. These currents are normally generated in the bulk silicon of the detector. The dark current scales with operating temperature and exposure time. The dark current is reduced by approximately half for each 7℃ of cooling. Dark current has statistical variation called “dark noise”.


Please refer to this link if you would like to investigate the “dark noise” further.


Data transfer interface (I/F)

The protocol and hardware for transferring the image data from the camera to the computer.  The speed of the data interface can be a limiting factor in transferring image data for computer storage. 

Defect pixel correction

As all CMOS image sensors have defect pixels. To reduce the effect of the defect pixels, Hamamatsu sCMOS camera has a real-time defect pixel correction feature. This correction is performed in real-time with no impact on image readout speed. The correction function can be turned on or off using the software, and the camera defaults to the ON condition when powered up. 

Dynamic range

The term dynamic range refers to the range in which an image sensor is capable of accurately measuring the signal. Dynamic range is the ratio of maximum to minimum signal levels (detection limit) that can be detected. For an image sensor, the dynamic range is given by the full well capacity(pixel well depth) divided by the readout noise.
