Title:
DISPLAY SYSTEM
Document Type and Number:
Japanese Patent JP2023058541
Kind Code:
A
Abstract:
To provide a display system, an imaging device, a monitoring device, a display device and an electronic device which reduce power consumption.SOLUTION: In a display system, an imaging device IMAG operates in first and second imaging modes. In the first imaging mode, a digital processing circuit of the imaging device converts third imaging data captured by a first pixel into digital data and supplies the data to a display device as image data. In the second imaging mode, an analog processing circuit Analog of the imaging device detects difference data and sets a determination signal to an active value when there is a difference between the first imaging data and the second imaging data. A display device DISP operates in first and second display modes. In the first display mode, the image data is updated to display an image. In the second display mode, an image is displayed without an update of the image data. The switching of the imaging mode and the display mode is performed by setting the determination signal to an active value.SELECTED DRAWING: Figure 1
