Problems solved by technology
In other words, generally the image processing circuit can only receive and process the image data with the specific data format, if the image data generated by the image sensor does not conform to the specific data format, the image processing circuit cannot process The image data, which in turn leads to crashes or performance degradation
[0003] However, when the image processing system is first started or restarted, the image sensor is often in a relatively unstable state first, and then enters a stable state after a period of time
When the image sensor is in the unstable state, the image data generated by it often does not conform to the specific data format required by the image processing circuit, thus causing the above-mentioned problems in the image processing circuit

Embodiment Construction
[0059] Certain terms are used in the specification and subsequent claims to refer to particular components. It should be understood by those skilled in the art that hardware manufacturers may refer to the same component by different terms. This specification and subsequent patent applications do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The "comprising" mentioned throughout the specification and subsequent claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" here includes any direct and indirect electrical connection means. Therefore, if it is described in the text that a first device is coupled to a second device, it means that the first device can be directly electrically connected to the second device. second device, or indirectly electrically connected to the second device through other devices or co...

The invention relates to an image processing system comprising an image sensor, an image receiver and an image interface, wherein the image sensor is used for sensing a scene to generate an image datum; and the image interface is coupled between the image sensor and the image receiver for receiving the image datum output by the image sensor and judges the datum format of the image datum so as to selectively output the image datum to the image receiver. The invention also relates to an image processing method. In the invention, the image resolution of an image picture received by the image receiver can ensure the image picture conforming to the specification, and the problem of crash or efficiency reduction because the image receiver receives the image picture which does not conform to thespecification is avoided, thus improving the stability and efficiency of the image processing system.
Description
technical field [0001] The present invention relates to the related technical field of image processing, more specifically, to an image processing system and an image processing method for selectively outputting an image frame to an image receiver according to a data format of the image frame. Background technique [0002] In an image processing system, an image sensor is used to sense an external scene to generate corresponding image data. Then the image data will be sent to an image processing circuit for further processing the image data. Furthermore, when the image processing system is in a normal operating state, the image data is transmitted between the image sensor and the image processing circuit in a specific data format (eg, a specific image resolution). In other words, generally the image processing circuit can only receive and process the image data with the specific data format, if the image data generated by the image sensor does not conform to the specific da...
