Problems solved by technology

[0005] Although these two methods can realize the integration of multiple image sensors into the same device, the first method is a simple accumulation of image sensors, and two or more image sensor chips transmit images through their respective data output interfaces The data is transmitted to the main control chip of the device through the same data bus. Multiple image sensors share the same data bus. This connection method can easily cause data crosstalk and affect the image signal. In addition, the two image processing units in this integration method are actually Achieve the same function, resulting in a waste of chip area
The second method makes two image sensor chips share an image processing unit. Although it can solve the problem of mutual interference between the two image sensors, the independent image processing unit and parallel interface still occupy a large chip area.
Moreover, in the above two methods, the second image sensor chip still needs to include an analog signal processing unit, which is not conducive to reducing the chip size.

Embodiment 1

[0030] Such as image 3 As shown, the multi-image sensor image processing device comprising the MIPI interface in this embodiment is a master-slave dual-image sensor device, comprising a master image sensor chip 31, a slave image sensor chip 32 and a master control chip 33, wherein the master image The sensor chip 31 includes a master photosensitive array, an analog signal processing unit, a digital signal processing unit, an analog signal input interface and a MIPI interface, and the slave image sensor chip 32 includes a slave photosensitive array and an analog signal output interface.

[0031] Specifically, the master chip 33 controls the master image sensor chip 31 and the slave image sensor chip 32 through the control bus, wherein the master photosensitive array and the slave photosensitive array respectively included in the master image sensor chip 31 and the slave image sensor chip 32 are controlled by the master chip. , alternately enter the working state. Image proces...

Embodiment 2

[0040] Image 6 It is a schematic structural diagram of a module of the present invention applied to a dual-camera mobile phone. The two cameras in a dual-camera mobile phone are generally divided into a high-resolution image sensor placed on the back panel of the mobile phone and a low-resolution image sensor placed on the front panel of the mobile phone. The high-resolution image sensor is used to capture higher-resolution scenery Or people photos, the low-res image sensor is used for lower-res selfie shots or for video calls.

[0041] The high-resolution image sensor chip includes a high-resolution photosensitive array, an analog signal processing unit, a digital signal processing unit, an analog signal input interface, and a MIPI interface. Since mobile phones have high requirements for image quality when shooting scenes and portraits, dual-camera mobile phones The image sensor on the back panel of a mobile phone is generally a high-resolution camera with 300,000 to 12 mi...

Embodiment 3

[0048] Due to the development of 3D technology, many mobile phones, computers or network cameras have 3D shooting technology, so three or more image sensor chips are often integrated in such devices; Three or more image sensor chips. The following only takes a multi-image sensor device with three image sensors as an example for illustration.

[0049] Such as Figure 7a As shown, the image processing device includes a device main control chip, a control bus, a data bus, a master image sensor chip, a first slave image sensor chip and a second slave image sensor chip. The main image sensor includes a main photosensitive array, an analog signal processing unit, a digital signal processing unit, an analog signal input interface and a MIPI interface. The first slave image sensor chip includes a first slave photosensitive array and a first analog signal output interface. The second slave image sensor chip includes a second slave photosensitive array and a second analog signal outp...

Abstract

The invention provides a multi-image sensor image processing device with an MIPI (Mobile Industry Processor Interface) and a method, which comprise a main image sensor chip for catching image data, transmitting the image data into a main control chip through the MIPI after processing the caught image data, or receiving the image data caught from the image sensor chip, and transmitting the image data to the main control chip through the MIPI after processing the image data, one or more than one auxiliary image sensor chip for catching the image data and transmitting the caught image data to the main image sensor chip, and the main control chip for receiving the processed image data transmitted by the main image sensor chip. According to the invention, the area of an auxiliary image sensor can be compressed to be minimum, so that the phenomenon of data crosstalk can not be caused, the problem that in the prior art, the area of the chip of multi-image sensor equipment is wasted is effectively solved and the cost of the multi-image sensor equipment is reduced.
