Abstract: A method for authentication data transmission and a system thereof are provided. The method is operated in a computer system that is connected to a biometric device, and a secure channel is established there-between according to a security protocol. The computer system can receive encrypted biometric feature data from the biometric device based on a request. In a secure environment built in the computer system, the biometric feature data is decrypted and biometric features can be extracted. A comparison result is generated after comparing the biometric features with feature data in a database. The comparison result can be transmitted to the biometric device. The comparison result is then encrypted in the biometric device according to the security protocol.

Abstract: The present disclosure discloses a multi-path image processing apparatus. An image merging circuit is configured to receive image frames that at least one of the image frames has a largest row number, generate redundant pixel row for each of the image frames that has a row number smaller than the largest row number such that the row number of each of the image frames equals to the largest row number, generate redundant pixel columns for each of the image frames having the number thereof determined by a size of a largest operation window, and merge each two of the image frames through the redundant columns thereof to generate a merged image frame. An image processing circuit performs image processing procedure on the merged image frame to generate a processed merged image frame, wherein at least a part of the image processing procedure is operated according to the largest operation window. An image segmentation circuit segments the processed merged image frame to generate processed image frames.

The unlocking method includes: receiving a first sound extraction request by a first processing circuit when the electronic device is in a locked mode; determining, by the first processing circuit, whether a first voice input signal is received after receiving the first sound extraction request; determining, by the first processing circuit when the first processing circuit receives the first voice input signal, whether first voice data included in the first voice input signal matches first preset voice data; and transmitting, by the first processing circuit, the first voice input signal to the second processing circuit when the first voice data matches the first preset voice data, to trigger the second processing circuit to determine whether second voice data included in the first voice input signal matches second preset voice data.

Abstract: This invention discloses a data storage chip and a data access method. The data access method is applied to a memory that includes a first area having a first range of memory address and a second area having a second range of memory address. The first range of memory address and the second range of memory address do not overlap. The method includes steps of: reading a predetermined address of the first area to obtain a control value; receiving a memory read command containing a target address; accessing the first area according to the memory read command when the target address is within the first range of memory address, and accessing the second area according to the memory read command when the target address is within the second range of memory address; and selectively sending the data read from the first area according to the control value.

Abstract: A saturation adjusting apparatus for processing a pixel, which has three color components each having a value falling within a range defined by upper and lower extreme values, of a RGB color model includes an extreme value controller and a component adjuster. The extreme value controller determines maximum and minimum extreme value thresholds for ensuring that the values of the color components of the pixel after undergoing linear color correction processing based on a correction indicator fall within the range defined by the upper and lower extreme values. The component adjuster includes a decision-making unit for choosing the correction indicator from a group of values which includes the maximum extreme value threshold, the minimum extreme value threshold, and a saturation setting. The component adjuster further includes a color corrector for performing linear color correction processing on the three color components of the pixel using the correction indicator.

Abstract: An edge detection apparatus includes a computing circuit and a determining circuit. The computing circuit includes a first multiplier block and a first adder unit. The first multiplier block includes n×m first multiplier units, wherein each first multiplier unit has a first multiplication factor. The n×m first multiplier units respectively perform multiplications on n×m pixels which are arranged as an n×m matrix to generate n×m first product values based on the corresponding first multiplication factors. The n×m pixels include a target pixel, where n is not equal to m. The first adder unit generates a first computation result according to the n×m first product values. The determining circuit determines if the target pixel is an edge pixel according to at least the first computation result.
