A bus packet format displaying method for a logic analyzer is disclosed. The logic analyzer fetches at least one packet of a bus of an electronic device. A computer host divides a plurality of bits of a second packet section of the packet into a plurality of message partitions according to a predetermined format defined in advance. Each of the message partitions has a value. The computer host gives a message name to each of the message partitions corresponding to the values and displays the message names and the values fetched by the logic analyzer on an operating screen.

Bus packet format displaying method for logic analyzer

A logic analyzer includes a probe, an FPGA module, a first transmission interface, a storage module, and a second transmission interface. A method of retrieving data includes the following steps: retrieving a digital signal through the probe, integrating the digital signal into a piece of signal data through the FPGA module, retrieving the piece of signal data through the first transmission interface, saving the piece of signal data in the storage module through the first transmission interface with a first transmission rate, returning the piece of signal data saved in the storage module to the FPGA module through the first transmission interface, receiving and transmitting the piece of signal data to the computer through the second transmission interface with a second transmission rate, whereby to save the piece of signal data therein. A method of performance testing includes testing multiple objects to correspondingly generate a response time triggered by a digital signal, whereby to analyze the performance of the objects.

An image cropping process of a multifunction peripheral is provided. Firstly, a top edge endpoint of an object image is searched from a band image of an original image. Then, each band image of the original image is read to search the object endpoint coordinate of a to-be-printed object image zone. The object image zone is outputted to be printed. The image cropping process further provides a strategy for detecting spots in order to enhance the accuracy of searching the object image.

Image cropping process

An image processing method, for receiving an input image and separating pixels having text characteristics and pixels having figure characteristics, includes: applying a first filtering processing for the input image to derive a first image processing result; applying a second filtering processing for the first image processing result to derive a second image processing result, wherein a distribution of filtering parameters of the first filtering processing is different from a distribution of filtering parameters of the second filtering processing; deriving a set of first reference values according to the first image processing result and the second image processing result; and determining whether each pixel within the input image is a text pixel or a figure pixel according to at least the set of the first reference values and a predetermined threshold.
