Below in conjunction with accompanying drawing the technical scheme that the embodiment of the invention provides is described.
Referring to Fig. 1, a kind of image processing method that the embodiment of the invention provides comprises step:
S101, obtain the configuration parameter information of image display.
S102, according to the configuration parameter information of image display, the image that image capture device is collected carries out pre-service.
S103, will pass through the pretreated image of step S102 and send to image display.
Preferably, the configuration parameter information of image display comprises:
The information whether video card need carry out stretch processing to image; And/or,
The information of RGB (RGB, the Red Green Blue) color mode that display screen is supported.
Wherein, When the configuration parameter information of image display comprises that video card need carry out the information of brightness or chromaticity range stretch processing to image; Then among the step S 102 according to the configuration parameter information of said image display, the image that image capture device is collected carries out pre-service and comprises:
The RGB data of [0,255] scope of the image that image capture device is collected convert Y data of [16,235] scope and the UV data of [16,240] scope into.
When the configuration parameter information of image display comprises that video card need not carry out the information of brightness or chromaticity range stretch processing to image; Then among the step S102 according to the configuration parameter information of said image display, the image that image capture device is collected carries out pretreated step and comprises:
The RGB data of [0,255] scope of the image that image capture device is collected convert the yuv data of [0,255] scope into.
The information that comprises the RGB color mode that display screen is supported when the configuration parameter information of image display; And when the RGB color mode of this display screen support is AD HOC; Then among the step S102 according to the configuration parameter information of image display, the image that image capture device is collected carries out pretreated step and comprises:
The image of the RGB24 pattern that image capture device is collected converts the image of said AD HOC into.
Wherein, the AD HOC described in the embodiment of the invention comprises: polytype color modes such as RGB565, RGB555, RGB444.If detect RGB color mode that display screen supports for for wherein a certain color mode the time, the image transitions of the RGB24 pattern that just need image capture device be collected is the image of the RGB color mode of display screen support.
In the embodiment of the invention; Can be in the image capture chip built-in figure image intensifying engine; Be used for inquiring about attributes such as local image display (like LCDs LCD) and video card processing power; And adjust the correlation parameter in the image capture chip accordingly according to these information, so that the image or the video data of picked-up obtain best viewing effect on local image display.
Referring to Fig. 2, a kind of image capture chip that the embodiment of the invention provides comprises:
Enquiry module 101 is used to obtain the configuration parameter information of image display.
Image processing module 102 is used for the configuration parameter information according to image display, and the image that collects is carried out pre-service.
Transport module 103 is used for process image processing module 102 pretreated images are sent to image display.
Particularly, transport module 103 can adopt the mode of USB will pass through said image processing module 102 pretreated images and send to image display.
Preferably, said image processing module 102 comprises one of the following units at least:
Unit 201 reduces the scope; Be used for when information that enquiry module 101 obtains comprises that video card need carry out the information of brightness or chromaticity range stretch processing to image; RGB data with [0,255] scope of the image that collects convert [16 into; 235] the UV data of the Y data of scope and [16,240] scope.
Direct converting unit 202; Be used for when information that enquiry module 101 obtains comprises that video card need not carry out the information of brightness or chromaticity range stretch processing to image, with the RGB data of [0,255] scope of the image that collects; Convert the yuv data of [0,255] scope into.
