Embodiment Construction

[0024] The present application is described below based on the embodiments, but the present application is not limited to these embodiments. Some specific detail portions are described in detail in the detailed description of the present application. The description of these detail portions without these detailed parts can also be fully understood. In order to avoid obscuring the essence of this application, a well-known method, process, and processes have not been described in detail. The drawings are not necessarily drawn to scale.

[0025] The following terms are used herein.

[0026] Multi-exposure video data: When the video data is acquired, each frame image uses two or more exposure time parameters to perform image acquisition, obtain video data including at least two image frames corresponding to different exposure time, called more Exposure video data. According to the exposure time parameters employing the camera, the multi-exposure video data may include a long exposure ...

Abstract

The embodiment of the invention provides a signal processing unit and method, an acceleration unit, electronic equipment and a system on chip, the signal processing unit is used for processing video data transmitted to a digital video interface, and the signal processing unit comprises a control unit and a pulse generation unit; the control unit is used for acquiring configuration information for multi-exposure video data, and the multi-exposure video data comprises at least two kinds of image frames corresponding to different exposure times; the pulse generation unit is used for receiving the multi-exposure video data and generating at least one frame synchronization pulse on a first frame synchronization signal included in the multi-exposure video data according to a row effective signal and configuration information included in the multi-exposure video data so as to obtain a second frame synchronization signal, and enabling the second frame synchronization signal to comprise a frame synchronization pulse corresponding to each image frame in the multi-exposure video data, and sending the second frame synchronization signal to the digital video interface. According to the scheme, the applicability of the signal processing unit can be improved.

Description

Technical field [0001] The present application relates to the field of chip technology, and more particularly to a signal processing unit, a method, an acceleration unit, an electronic device, and a chip system. Background technique [0002] With the continuous development and advancement of image processing technology, the image processing chip is widely used in visual scenarios, such as under smart speakers, brush payment and other application scenarios, face recognition by image processing chip. Under different application scenarios, the image processing chip needs to process the image data collected by different types of cameras, and the same image processing chip may need to collect image data acquired by multiple cameras as an input source, different types of cameras to collect image data. There is a difference in format, such as some camera collected images have the same exposure time, while the images collected by the other cameras have a variety of exposure times, while ...
