Abstract: A method for detecting an object utilizing a monocular camera obtains an image showing an object and determining a pixel coordinate of the object in the image and determining a spatial position of the object in the image, based on the pixel coordinate of the object in the image and a preset coordinate transformation relationship or a preset depth prediction model. The image showing the object is obtained through the monocular camera, and the pixel coordinates of the object in the image are determined. According to the pixel coordinates of the object in the image and the preset coordinates transformation relationship or the preset depth prediction model, the spatial position of the object in the image is determined, providing efficient and accurate detection. An electronic device and a non-transitory storage recording the method are also disclosed.

Abstract: An ultrasonic ranging device includes an ultrasonic transmitter, an ultrasonic transmitting/receiving circuit, and a controller. The ultrasonic transmitter includes transmitting channels arranged in a ring. Each of the transmitting channels transmits a first ultrasonic wave. The first ultrasonic wave is reflected by a target object, the reflection of the first ultrasonic wave is defined as a second ultrasonic wave. Each of the transmitting channels receives the second ultrasonic wave. The ultrasonic transmitting/receiving channel controls the ultrasonic transmitter to transmit the first ultrasonic wave or receive the second ultrasonic wave by switching between working modes. The controller obtains a distance to the target object according to a transmitting time of the first ultrasonic wave and a receiving time of the second ultrasonic wave.

Abstract: A face sensing module for a computing device includes a frame, a depth sensor, and an RGB camera. The frame includes first and second side portions and a cross portion. The depth sensor includes first and second infrared cameras, and an infrared light emitting unit. The first infrared camera is mounted on the first side portion. The second infrared camera is mounted on the second side portion. The infrared light emitting unit is mounted on the cross portion, with an infrared emitter and an infrared guide. Infrared light emitted is guided out. The RGB camera is mounted on the first side portion. The first and second infrared cameras and the RGB camera are optically aligned before being mounted together inside the housing of the computing device to ensure precise mountings and the durability of precise alignment notwithstanding handling by a user.

Abstract: The present invention provides an auto-exposure power-saving device, which comprises an image brightness calculation unit for calculating the brightness value of an image. A maximal tolerable brightness value and a minimal tolerable brightness value both set by a CPU of a digital still camera (DSC) are inputted to a first comparator and a second comparator. The first comparator is used to compare the image brightness value with the maximal tolerable brightness value and then output a first comparison signal. The second comparator is used to compare the image brightness value with the minimal tolerable brightness value and then output a second comparison signal. The CPU is then activated or not according to the first or second comparison signals. The present invention has the power-saving advantage and a longer lifetime of use.
