Abstract: A testing system for an image processing algorithm including a control unit, an image processing device, an image processing hardware, and a testing device is disclosed. The control unit provides an original image and parameters. The image processing device obtains the original image and the parameters, and drives the image processing hardware to perform a first image processing procedure to the original image based on the parameters to generate a hardware-processed image. The testing device obtains the original image, the parameters, and the hardware-processed image, and performs, through a simulation software, a second image processing procedure to the original image based on the parameters to generate a software-processed image. The testing device compares the hardware-processed image with the software-processed image through a testing software to generate a comparing result that shows a pixel difference of the hardware-processed image and the software-processed image.

Abstract: A correcting method of a real-time image is disclosed and includes: continuously receiving real-time images from an image inputting device; analyzing an image feature in each real-time image; computing a motion vector of each real-time image based on a feature difference between any two time-adjacent real-time images; computing a moving trajectory predicted value of a latest real-time image based on accumulated motion vectors; computing a compensation value of the latest real-time image when determining that a difference between the moving trajectory predicted value and the motion vector of the latest real-time image is within a correction allowable range, and correcting the latest real-time image by the compensation value; and, resetting the image inputting device and outputting a default image when determining that the difference between the moving trajectory and the motion vector of the latest real-time image exceeds the correction allowable range.

Abstract: A displaying equipment at least including an image controlling module, a primary system module, and a system controlling module is disclosed. The image controlling module continuously receives an input image from an image sensitive device after activates, and directly outputs the received input image. The system controlling module constantly monitors the primary system module after activates to determine whether the primary system module activates completely. The primary system module runs an operating system after being activated to process the input image and to generate a processed image. After the primary system module activates completely, the image controlling module outputs both the input image and the processed image simultaneously. When the primary system module is abnormal, the image controlling module restores to output the input image only.

Abstract: A calibrating device of calibrating a real-time image through a dithering process including a receiving unit, a storing unit, a displacing module, a computing module, and an outputting unit is disclosed. The receiving unit receives a real-time image from an image sensor and records a time parameter of the image. The storing unit stores a hash table that records multiple hash values used to calibrate the image. The displacing module shifts the multiple hash values in the hash table to generate an adjusted hash table. The computing module obtains a corresponding hash value from the adjusted hash table for each pixel point of the image in accordance with the coordinates of each pixel point, and respectively adds the corresponding hash value to the pixel value of each pixel point of the image to generate a calibrated image. The outputting unit outputs the calibrated image.
