Abstract

The invention provides an image processing device and mobile computing device having the same. The image processing device comprises: a pixel array including a plurality of pixels, wherein the plurality of pixels comprises a first pixel and a second pixel, the first pixel comprises a first photodiode and a second photodiode, and the second pixel comprises a third photodiode and a fourth photodiode, and the first to fourth photodiodes are configured to generate an image signal; an image data processing circuit configured to generate image data based on the image signal; and a processing circuit configured to extract color data from the image data and extract depth data from the image data. The first photodiode and the second photodiode are formed in the silicon substrate, the first deep trench isolation (DTI) locates between the first photodiode and the second photodiode, the third photodiode and the fourth photodiode are formed on the silicon substrate, and the second DTI locates between the third photodiode and the fourth photodiode.

Description

[0001] This application is a divisional application of an invention patent application with the title of "Image Processing Device and Mobile Computing Device with the Image Processing Device" and the application number of 201510209510.4 on April 28, 2015 as the filing date. Technical field [0002] Embodiments of the inventive concept relate to an image processing device, and more particularly to an image processing device capable of outputting color data and depth data extracted from data output from a full PAF pixel array in a parallel manner and / or a serial manner, and A mobile computing device including the image processing device. Background technique [0003] PAF stands for Phase Detection Auto Focus or Phase Difference Auto Focus. In the field of photography, the dynamic range is the range between the maximum measurable light intensity and the minimum measurable light intensity. The degree of change in light intensity depends on the device used as an image capture device, ...
