Image sensors and cameras play a key role in Smart City, Internet of Things or security applications such as sensing, imaging, and video analysis. The OV02718-H77T is a new image sensor from OmniVision that provides high-resolution image capture and vivid colors with low power consumption. This image sensor is ideal for applications such as facial recognition, QR code, and Augmented Reality (AR).

The OV02718-H77T image sensor is an 8.9 megapixel (MP) high-resolution sensor that supports full-frame output or 3x3 frame output, allowing it to capture up to a maximum of 25 frames per second. The sensor also supports different aspect ratios such as 16:9, 4:3, 3:2, and 1:1. The sensor has an active array size of 2816H x 2112V and its minimum resolution is 640 x 480. The OV02718-H77T has two operating modes: normal and HDR. The normal mode is used for low-light applications and the HDR mode is used for bright scenes. This image sensor has an integrated 4-lane MIPI interface, which can be used to output outputs in 4-lane (1600 Mbs/lane) or 2-lane (800 Mbs/lane). The power consumption of the sensor is very low and it can be powered from a single power supply of 1.8V to 3.3V.

The OV02718-H77T image sensor has an integrated digital processing pipeline, which enhances image quality and reduces motion artifacts. The digital pipeline consists of a DC balancing, high dynamic range (HDR) and geometrical distortion correcting block. The DC balancing block is used to reduce the DC offset in the image signal, while the HDR block reduces noise and provides more vivid colors under low light conditions. The geometrical distortion correcting block eliminates distortions such as barrel distortion, pin cushion distortion, and vignetting by applying digital filters.

In addition to the digital processing, the OV02718-H77T image sensor can also be configured to perform digital zoom, exposure control, and exposure monitoring. The digital zoom feature can be used to zoom in or out on the image without any loss of quality. The exposure control allows the user to adjust the brightness and contrast in the image. The exposure monitoring feature can detect when the image is overexposed or underexposed and alert the user. In addition, the OV02718-H77T supports motion detection, which is used to detect motion in the image.

The OV02718-H77T image sensor is an excellent choice for applications requiring high-resolution image capture, low power consumption, and vivid colors. The integrated digital processing pipeline enhances image quality and reduces noise, while the advanced features such as digital zoom, exposure control, exposure monitoring, and motion detection make this sensor a powerful imaging solution for a wide range of applications.
