Image Signal Processor (ISP)

The world's leading mobile phone and digital camera manufacturers have chosen to work with DxO in improving image quality, adding new features, and reducing component costs. DxO imaging systems cover a broad range of digital imaging technologies, from complete image signal processors (ISPs) to feature add-ons, using processes and techniques that ensure optimal image quality.
 
Consumers and professionals now expect a high level of image quality and features while enjoying the convenience of having a single device that is lightweight, powerful, and energy efficient. For this reason DxO has developed a camera ISP for implementation within a mobile phone’s baseband or a processor or fpga, perfectly suited for a wide range of applications.
 

High quality still and video camera technologies

DxO ISP delivers high-quality images even in very low light, using all types of optics and image sensors including small pixel sensors designed for mobile devices. Benefiting from the features of its DxO Optics Pro professional photography software, DxO ISP includes a range of noise reduction techniques ensuring the highest quality images possible. Other features include adaptive real-time exposure control, focus, and white balance (DxO 3A) allowing DxO ISP to deliver consistent colors (DxO AutoCLS), contrast and details—whatever the lighting conditions.
