Digital image processing

Abstract

A method, module, device, and computer program product for digital imaging. Providing an image within an image sensor, selecting at least one first region within image for scaling with a first scaling rate, selecting at least one second region within the image for scaling with a second scaling rate, and providing the first and the second regions for further processing allows improved autofocusing.

Description

technical field

[0001] This patent application relates generally to digital image processing in digital imaging devices. Background technique

[0002] In the past few years, digital imaging devices such as digital cameras have played a significant role in imaging technology. Conventional cameras rely entirely on chemical and mechanical processes and generally do not require electricity to operate. However, digital cameras have one or more built-in processors, and these cameras record images entirely digitally. Due to its electrical characteristics, digital cameras (or digital camera modules) can be easily integrated with other electronic devices, of which mobile communication devices (mobile terminals) are the most common example today. Depending on the host device (ie, the device with which the camera module is integrated), the camera module may communicate with several other components and systems of the device. For example, in a camera phone, the camera module is typic...
