An image processing method and apparatus for a smart pen, and an electronic device are provided in embodiments of the present disclosure, and belong to the technical field of data processing. The method comprises: monitoring a working state of a second pressure switch provided at a pen tip of the smart pen when the smart pen is in a working state; controlling an infrared transceiver circuit on the smart pen to send an infrared signal to an area where the smart pen writes; performing feature calculation on an original image by using a first part of a preset lightweight network model; performing feature retrieval on a first feature image to obtain a trajectory identification result corresponding to the original image; and sending, by means of a Bluetooth module on the smart pen, a trajectory vector to a target object with which the smart pen establishes a communication connection.

The present invention relates to a device for skin condition analysis and skin disease diagnosis. The skin condition analysis and skin disease diagnosis device according to the present invention is an all-in-one type device that can perform not only cosmetic skin condition analysis but also diagnosis of medical skin disease items.

A method to optimize learning based upon ocular information of a subject includes providing a video camera for recording a close-up view of a subject's eye. A first electronic display shows a plurality of educational subject matter to the subject. A second electronic display shows an output to an instructor. Changes in ocular signals of the subject are processed through the use optimized algorithms. A cognitive state model determines a low to a high cognitive load experienced by the subject. The cognitive state model is evaluated based on the changes in the ocular signals for determining a probability of the low to the high cognitive load experienced by the subject. The probability of the low to the high cognitive load experienced by the subject is displayed to the instructor.

Color accuracy in an imaging device is improved.

An imaging element includes a plurality of pixels that acquires first information that is information of three primary colors and second information that is information of at least two colors different from the three primary colors and that includes at least one of complementary colors of the three primary colors.

Disclosed is a biometric information acquisition system and a processing method thereof. The biometric information acquisition system comprises a transparent substrate; a light source; a photoelectric conversion device, which is located at one side of the transparent substrate with the light source, receives light reflected by the transparent substrate and generates electrical signals; a processing device for obtaining biometric information based on the electrical signals. At least a portion of the transparent substrate is made of flexible material, and fits a predetermined portion of an organism on the other side of the transparent substrate based on a curved interface, therefore, ambient light incident to the photoelectric conversion device is reduced, an interference caused by the ambient light is reduced, accuracy of acquiring biometric characteristic information is improved. Because fitting with the curved interface can increase contact area, more biometric characteristic information of the predetermined portion can be obtained.

A method and verification system for verifying pharmaceuticals packaged within a pouch using a pharmacy packaging system. The method includes activating a first light source to illuminate the pharmaceutical pouch, capturing a first image of the pharmaceutical pouch while illuminated by the first light source, activating a second light source to illuminate the pharmaceutical pouch, and capturing a second image of the pharmaceutical pouch while illuminated by the second light source. The method further includes generating a third image based on the first image and the second image, generating a dashboard to simultaneously display first images, second images, and third images from a plurality of pharmaceutical pouches, providing a number of pills indication of a number of pills detected in the pouch against a number of pills expected in the pouch, and displaying the dashboard.

In a method for estimating thermal sensation, thermal environment information at least regarding a thermal environment of or around a person is obtained, (1) a method for estimating a first thermal sensation, (2) a method for estimating a second thermal sensation, or (3) both the method for estimating the first thermal sensation and the method for estimating the second thermal sensation is selected as a method for estimating thermal sensation, which indicates a degree of warmth or coldness of the person, on the basis of the thermal environment information, and the thermal sensation is estimated using the selected method.

An analysis method for breast image and an electronic apparatus using the same are provided. The method includes the following steps. A breast image scanned by an ultrasound wave is obtained. Based on rectangular features of the breast image, a region of interest including an aberrant region in the breast image is obtained by applying a detection model. The aberrant region is further acquired from the region of interest, and a plurality of feature parameters of the aberrant region are extracted for a property analysis of the aberrant region.
