As shown in FIG. 7, the image processing circuit may include an image signal processing (ISP) processor 740 and a control logic 750. The image data captured by the imaging device 710 is first processed by the ISP processor 740, and the ISP processor 740 analyzes the image data to capture image statistical information used to determine control parameters of the imaging device 710. The imaging device 710 may be a camera having a lens 712 and an image sensor 714. The image sensor 714 may include a color filter array (such as a Bayer filter). Each imaging pixel of the image sensor 714 may capture light intensity and wavelength information of ambient light. The image sensor 714 transmits the original image data to the ISP processor 740. The sensor 720 may provide the original image data to the ISP processor 740 based on a preset interface. The preset interfaces include a Standard Mobile Imaging Architecture (SMIA) interface, other serial or parallel camera interfaces, or a combination of the foregoing interfaces.

The ISP processor 740 processes the original image data pixel by pixel in a variety of formats. For example, each image pixel may have a bit depth of 8, 10, 12, or 14 bits, and the ISP processor 740 may perform one or more image processing operations on the original image data and collect statistical information about the image data. The image processing operations may be performed with the same or different bit depth accuracy.

The ISP processor 740 may also receive pixel data from the image memory 730. For example, the original pixel data is sent to the image memory 730 from a preset interface, and the original pixel data in the image memory 730 is then provided to the ISP processor 740 for processing. The image memory 730 may be a partial storage space of the memory, or an independent dedicated memory, and its type may be a direct memory access (DMA).

When receiving raw image data from a preset interface or from the image memory 730, the ISP processor 740 may perform image processing operations, such as filtering processing. The processed image data may be sent to the image memory 730 for further processing before display. The ISP processor 740 receives the processing data from the image memory 730, and performs image data processing on the processing data in the original domain and in the RGB and YCbCr color spaces. The processed image data may be output to a display 770 for viewing by a user and / or further processed by a graphics engine or a graphics processing unit (Graphics Processing Unit, GPU). In addition, the output of the ISP processor 740 may also be sent to the image memory 730, and the display 770 may read image data from the image memory 730. In one embodiment, the image memory 730 may be configured to implement one or more frame buffers. In addition, the output of the ISP processor 740 may be sent to an encoder / decoder 760 to implement encoding / decoding of image data. The encoded image data can be saved and decompressed before being displayed on the display 770 device. The encoder / decoder 760 may be implemented by a CPU or a GPU or a coprocessor.

The statistical data determined by the ISP processor 740 may be sent to the control logic 750 unit. For example, the statistical data may include image sensor 714 statistical information such as auto exposure, auto white balance, auto focus, flicker detection, black level compensation, and lens 712 shading correction. The control logic 750 may be a processor and / or a microcontroller, and one or more routines may determine control parameters of the imaging device 710 according to the received statistical data. For example, the control parameters may include sensor 720 control parameters (such as gain, integration time for exposure control), camera flash control parameters, lens 712 control parameters (such as focal length for focusing or zooming), or a combination of these parameters. ISP control parameters may include gain levels and color correction matrices for automatic white balance and color adjustment (eg, during RGB processing), and lens 712 shading correction parameters.
