Definitions
- the image processing chip includes a plurality of functional modules, and the abnormality information is obtained by self-testing of each functional module.
- the embodiment of the third aspect of the present disclosure proposes an electronic device, including a memory, a processor, and an exception handling program that is stored in the memory and can be run on the processor and applied to the image processing chip.
- the processor executes When applied to the exception handling program of the image processing chip, the aforementioned exception handling method applied to the image processing chip is implemented.
- FIG. 4 is a schematic structural diagram of an image anomaly detection and processing module of an image processing chip according to an embodiment of the disclosure
- the processing of the exception is mainly to directly return an error number to the hardware abstraction layer of the camera, so that the hardware abstraction layer of the camera handles the exception.
- the image processing chip finds an abnormality, it will mark the corresponding functional module that has the abnormality, and directly shut down the functional module that has the abnormality.
- the image processing chip directly shuts down and throws an exception, so that the hardware abstraction layer of the camera handles the exception.
- the image processing chip cannot detect the image abnormality, and directly outputs the abnormal image, so that the user can see the abnormality. Therefore, whether the image processing chip feeds back the abnormal type to the calling function or directly crashes, it will make the upper hardware abstraction layer visible, thus affecting the use of the upper hardware abstraction layer and the user experience effect.
- the electronic device includes an image collector, which is used to collect image data for preview or shooting.
- the image collector sends the collected image data to the image processing chip.
- the image processing chip is used to process the received image data and output it to the upper hardware abstraction layer after processing.
- the image processing chip can use its own abnormal detection mechanism to detect the abnormality and obtain abnormal information.
- the simulated current frame image can be sent to the hardware abstraction layer as the output frame image, so that the hardware abstraction layer controls the display to display the simulated current frame image, thereby avoiding the output image freeze, so that The user is not aware of the abnormality of the underlying image processing chip, which improves the user experience.
- various parts of the present disclosure may be implemented in hardware, software, firmware or a combination thereof.
- various steps or methods may be implemented by software or firmware stored in memory and executed by a suitable instruction execution system.
- a suitable instruction execution system For example, if implemented in hardware, as in another embodiment, it can be implemented by any one or combination of the following techniques known in the art: Discrete logic circuits, ASICs with suitable combinational logic gates, programmable gate arrays (PGAs), field programmable gate arrays (FPGAs), etc.

Abstract
Puce de traitement d'image, et procédé de traitement d'anomalie appliqué à une puce de traitement d'image. Le procédé comprend les étapes suivantes : acquisition d'informations d'anomalie dans un processus de sortie d'image, et détermination d' un type d'anomalie selon les informations d'anomalie (S101) ; et avant de rapporter les informations d'anomalie, selon le type d'anomalie, commande d'un module de fonction d'anomalie dans une puce de traitement d'image pour réaliser de nouvelles tentatives et/ou commander le module de fonction d'anomalie pour commuter vers un mode de dérivation, de façon à réaliser un traitement d'auto-récupération d'anomalie sur la puce de traitement d'image (S103).
