Problems solved by technology
However, existing image processing methods for mobile phones with cameras have disadvantages: see figure 1 , the mobile phone with camera includes functional modules such as camera module 20', baseband module 30' and LCD module 10', wherein camera module 20' includes lens, optical sensor and image processor
Moreover, the realization of each process also requires the master controller in the baseband module 30' to control and coordinate, which undoubtedly increases the burden on the baseband module 30' and causes the load of the baseband module to be too large; and because the camera module 20' captures The image needs to be transmitted to the LCD module 10' after passing through the baseband module 30', so there is a delay of several frames of images between the image displayed on the LCD module 10' and the actual picture
The existence of these defects makes the mobile phone with the camera unsatisfactory in actual operation, so there is an urgent need for a method that enables the camera module 20' to interact with the LCD module 10' without passing through the baseband module 30'. Image processing method for image data transfer

Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] A method for image processing in a mobile phone with a camera, including a preview mode, a still image capture mode, a post-capture display mode, and a video capture mode.
[0022] see figure 2 , the steps of preview mode among the present invention are: 1) CCD / CMOS image sensor sends YUV image data to SIF / ISP unit; 2) SIF / ISP unit sends image data to image size management unit to process; 3) Image size management The image data processed by the unit is converted into YUV-RGB by the YUV-RGB converter; 4) The converted image data is stored in the frame buffer; 5) The frame buffer sends the image data to the LCD VIEW unit for Gamma correction and color depth Processing; 6) The processed image data is sent to the LCD driver interface unit and displayed by the LCD module.
[0023] Step 4) of the above preview mode further includ...

The invention discloses a kind of image process method in mobile communication terminal which has an image head, which belongs to image process filed. The invention can carry on the transmission of image data between the image model and the LCD model without through the baseband model, it reduces the burden of baseband model, eliminates the delay between the displayed image of LCD model and the actual image. The invention includes previewing mode, static image capturing mode, captured displaying mode and video frequency capturing mode.
Description
technical field [0001] The invention relates to an image processing method, in particular to an image processing method used in a mobile communication terminal with a camera. Background technique [0002] With the rapid development of digital image technology, various digital camera or image processing products have generally entered the lives of ordinary people. As the core technology of the digital image field, there are many types of image processors, and their functions are also increasingly enhanced. There are not only image processors for individual digital cameras, but also image processors for mobile communication terminals with embedded cameras such as mobile phones or personal handheld computers. It can not only help mobile phones to display images, but also Capable of image acquisition and multimedia communication through the mobile phone, this composite mobile phone improves the efficiency of applications and greatly facilitates users. However, existing image p...
