Embodiment Construction
[0013] like figure 1 Shown is a hardware architecture diagram of a preferred embodiment of the iris lens detection device of the present invention. The hardware architecture diagram includes an iris lens detection device 1 and a digital photography device 2 . The iris lens detection device 1 includes a microcontroller (Micro programmed Control Unit, MCU) 10 , multiple groups of light sources 11 and a display 12 . In this embodiment, the multiple groups of light sources 11 are connected in parallel to the MCU 10 . The MCU 10 includes a clock unit 100 for providing the MCU 10 with system time.
[0014] The digital photography device 2 includes: an iris lens 20 , a light sensor 21 , a System on Chip (SoC) 22 and an iris lens control circuit 23 . The MCU 10 communicates with the SoC 22 through an I2C (Inter-Integrated Circuit) bus or a console interface. The standard range of aperture magnification of the iris lens 20 corresponding to the brightness of each light source is sto...

The invention provides a detection device of an iris lens. The detection device is connected with a digital photography device, wherein the digital photography device comprises an iris lens, a photo sensor and a system single chip. The detection device of the iris lens comprises a microcontroller and a plurality of groups of light sources, wherein the microcontroller is used for receiving an order for turning on the light sources and an aperture magnifying power of the iris lens transmitted by the system single chip , controlling the light sources to be turned on according to the order for turning on the light sources, receiving an order for turning off the light sources and the aperture magnifying power of the iris lens transmitted by the system single chip when the aperture magnifying power of the iris lens is equal to 0, and controlling the light sources to be turned off according to the order for turning off the light sources. The invention further provides a detection method of the iris lens, so that the aperture adjustment of the iris lens can be exactly controlled.
Description
technical field [0001] The invention relates to a detection method, in particular to an iris lens detection device and detection method. Background technique [0002] The images taken by digital electronic products can only provide the ability of megapixels, so the automatic iris control design of the iris lens is introduced to improve the quality of photographic monitoring. The control of the automatic aperture is the average value of the light sent back by the sensing element of the sensor, and the size of the lens aperture is controlled according to the average value of the light. However, in the process of controlling the aperture size of the lens, the aperture adjustment accuracy of the iris lens usually cannot reach the preset value, so that the pixel quality of the image captured by the iris lens is not high. Contents of the invention [0003] In view of the above, it is necessary to provide an iris lens detection device and a digital photography device, which can ...
