Embodiment Construction

[0027] The method of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] For chip companies that develop image sensors and support image sensors, it is generally necessary to write corresponding behavior models for each image sensor that needs to be supported, resulting in problems such as low development efficiency and heavy workload. However, after research, it is found that the image sensors that can be seen at present have common features. Based on this commonality, the present invention proposes a general image sensor template format definition, and uses a software program to automatically generate an image sensor behavior simulation model according to specific parameters of the image sensor behavior simulation model to be generated.

[0029] For the image sensor, the main function is to output corresponding signals according to the definition of the register file, according to the corres...

Abstract

The disclosed generation method for an image sensor behavior simulation model comprises: defining general image sensor template with a memory module, an interface module and a top module; building HDL file corresponding to former modules; to generate model, modifying, adding or selecting parameter by software to a template, and writing into the HDL file to execute program and obtain the simulation model. This invention can avoid repeated exploit, reduces cost, and improve efficiency.

Description

[0001] Technology area [0002] The invention relates to the field of digital image acquisition, in particular to a generation device and method for an image sensor behavior simulation model. Background technique [0003] Generally, image acquisition and processing equipment includes three key components: lens (LENS), image sensor (SENSOR) and digital signal processing chip (DSP). The light comes in from the lens, reaches the photoreceptor, and the photoreceptor converts the light into a digital signal, and then sends it to a special DSP (digital processing chip) for image processing, and then it can be saved or displayed on the screen, that is, we see video image. [0004] With the development of digital technology and network technology, the distance between people is shrinking rapidly. From text to sound to image, the network communication is not only the brains of two people, the higher demand will be to simulate the communication between people. Face-to-face real conver...
