    Abstract: The present disclosure provides an ultrasonic imaging method and apparatus. The apparatus includes an ultrasonic signal emission source and a receiving array including ultrasonic signal receiving circuits; the method includes: turning on the source to perform emission of ultrasonic waves toward an object to be detected and causing the ultrasonic waves to propagate through the object, a depth-wise direction of which is along a propagation direction of the ultrasonic waves; after a first predetermined time period having elapsed since the source was turned on, turning on the receiving array to receive reflected echoes returning from a first section plane of the object to be detected perpendicular to the depth-wise direction; thereafter, turning off the receiving array, storing the reflected echoes by the ultrasonic signal receiving circuits and acquiring reflected echo signals, and successively reading the reflected echo signals from the ultrasonic signal receiving circuits during a reading time period.

    Abstract: An electronic device includes a pixel layer, an image display control apparatus, a photosensitive layer, and a processor. The pixel layer includes a plurality of pixel units configured to display an image. The image display control apparatus is configured to control the plurality of pixel units to sequentially display at least one corresponding first image according to at least one first image signal. The photosensitive layer is configured to receive a reflected light formed after an emergent light emitted from the pixel layer when displaying one first image at each time is reflected by an object to be photographed, and to convert the reflected light received at each time into a second image signal. The processor is configured to determine an image of the object to be photographed according to the at least one first image signal and second image signals corresponding to the at least one first image signal.
