Embodiment Construction
[0038] The present invention is to solve the problem that the image transmission rate is relatively slow in the USB1.1 mode, and to perform down-sampling and compression processing on the input image format size of the VGA image, under the premise of ensuring image quality and transmission rate, as much as possible reduce the cost of the chip.
[0039] The digital image processor involved in the present invention includes: some general image processing modules such as preprocessing module, interpolation module, automatic exposure control, automatic white balance, Gamma correction, color space transformation, contrast enhancement, color correction; In addition, the image processor It also includes a USB2.0 bus module and a USB1.1 bus module for image data transmission. In order to ensure the image data transmission of the USB1.1 mode, the present invention sets a mode based on USB1.1 in the digital image processor. The image data processing module is a functional module for pro...
