Embodiment Construction

[0023] As mentioned in the background art, currently, a multi-camera mobile device usually needs to configure an ISP chip for each camera, which will occupy additional space on the motherboard.

[0024] In addition, if the platform does not have enough data interfaces to connect corresponding multiple cameras, it is necessary to expand the camera interface through a MIPI switch. Usually, the MIPI switch can link the output terminals (transport, TX for short) of two different cameras. And connect the data to the input terminal (receive, RX for short) of the platform, and realize the switching between the two cameras by controlling the MIPI switch to select the data of one of the cameras during work. Or you can add the ISP chip between the MIPI switch and the platform, so that two cameras can share one ISP chip through the control of the MIPI switch.

[0025] However, the inventor found through research that using multiple ISP chips to support multiple cameras, or using a combin...

Abstract

The invention discloses an image signal processing device and a terminal, and the image signal processing device comprises an input module, a receiving module, an image processing module and a transmitting module. Wherein the input module is used for receiving image signals of a plurality of image signal sources, selecting one image signal and transmitting the image signal to the input end of the receiving module; the input end of the image processing module is connected with the output end of the receiving module, and the image processing module is used for processing the received image signal; the input end of the sending module is connected with the output end of the image processing module, and the output end of the sending module is used for outputting signals to the outside. The device can save the main board space of the multi-camera mobile equipment.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image signal processing device and a terminal. Background technique [0002] With the rapid development of mobile devices such as mobile phones, the camera function has attracted more and more people's attention. In order to make the camera effect of mobile phones closer to that of professional SLR cameras, it has become a trend to configure multiple cameras on one mobile device. Multiple cameras means that the platform needs to support multiple Mobile Industry Processor Interface (MIPI) camera interfaces, such as D-PHY, C-PHY, and only high-end data processing platforms (hereinafter referred to as platforms) can natively support 4 to 5 1 camera interface, where these cameras can include 1 front camera and 3 to 4 rear cameras; while the low-end platform has only 2-3 camera interfaces, which can support 1 front camera and 1 to 2 rear cameras camera. [0003] ...
