Camera circuitry and camera device

Abstract

This application discloses a camera circuitry and a camera device. The camera circuitry includes a light collection circuit, an operational amplification circuit, an image processor and a first resistor. The light collection circuit is used to collect the brightness value and pass the collected brightness value through the operational amplification circuit and the first resistor are then transmitted to the image processor, and the image processor initiate imaging based on the brightness value. By providing an operational amplification circuit and a first resistor at the back end of the light collecting circuit, and adopting a continuous power supply mode for the light collecting circuit and the operational amplification circuit, the convergence speed of the light brightness value is effectively improved, so that accurate ambient light brightness values can be obtained faster to achieve normal camera functions.
