Image Sensors, Camera has been widely used in home electronics, industrial 4.0, medicine, as well as military, making huge contribution into these fields. An image sensor, such as OV05648-G04A, has its own application field and working principle. The OV05648-G04A image sensor is an omnivision lighting sensor, featured with five megapixels, backside illuminated CMOS image and using a 1.4um pixel BSI technology, which works in a 1280*720 resolution. The application fields of this sensor are mainly on low illumination environment. It is suitable for mobile platform, such as security cameras, car rearview cameras, smart phones.The more popular usage is found in baby monitor and surveillance cameras. In baby monitor use, it helps parents to observe the condition of the baby at night. In surveillance use, it is applied in several solutions such as police-entrance identification, fingerprint capture, facial recognition, etc. It is also capable of various video recording and photo taking. As for the working principle, the OV--G04A sensor work the same logic. The operation of the sensor is based on CMOS technology, which allows two kinds of electric charges to be contained within a single image element, that is, a "pixel". By converting light energy to electric charge and then the electric charge to digital data, the sensor can process light from its surroundings and convert it into digital information that can be interpreted by other devices connected to it. When an image is sensed by the OV05648-G04A, the sensor first captures light in the field of view. Normal photon sensors gather the photons of the visible range spectrum and create a pattern of charges — quantifying the light energy —within each pixel. The incoming light is processed and made into a uniformed digital form for transfer of the images signal onto other devices connected to the sensor. Other external devices can then collect, process and interpret the data to display the image on the screen corresponding to the light levels variations taken in by the sensor. The OV05648-G04A applications and working principle are created to maximize the performance of the image sensor for different image recognition usages and low light performance under various lighting conditions. With the help of these sensor and its technology, image recognition becomes more reliable and accurate, making it popularly used in home surveillance and security systems in modern days.
