Portable image acquisition and compression device

The utility model relates to a portable image acquisition and compression device which comprises a CCD (Charge Coupled Device) figure camera and a host, wherein an image collecting module, a DSP (Digital Signal Processor) image processor, an image transformation and compression module, an ARM microcontroller, an image storage module and a communication module are arranged in the host, wherein the image collecting module is connected with the DSP image processor, the DSP image processor is connected with the ARM microcontroller, the ARM microcontroller is respectively connected with the image storage module and the communication module; a USB interface and a wireless interface are arranged in a housing of the host; and the CCD figure camera is connected with the host through a data wire. Because a wavelet transform image and compression technology is adopted for replacing the traditional DCT (Discrete Cosine Transform) transformation and compression technology, the portable image acquisition and compression device can realize higher compression efficiency, and is beneficial to storage and identification of image information and advanced application processing on an image in subsequent.
