Image coding and decoding method and device and electronic equipment

The embodiment of the invention discloses an image coding and decoding method, an image coding and decoding device and electronic equipment. The image coding method comprises the following steps: acquiring to-be-coded image data; obtaining a segmentation mode of the to-be-coded image data, and segmenting the to-be-coded image data based on the segmentation mode to generate a plurality of sub-image data; creating session control matched with the number of the sub-image data; and encoding the sub-image data based on the respective corresponding session control. According to the method, encoding is performed by segmenting the image and creating the matched session control, and the mode is realized through software side program scheduling and is not limited by the hardware performance of the encoder. 本公开实施例公开了一种图像编码及解码方法、装置和电子设备。该图像编码方法包括：获取待编码的图像数据；获取待编码的图像数据的分割方式，并基于分割方式对待编码的图像数据进行分割，生成多个子图像数据；创建与子图像数据的个数匹配的会话控制；将子图像数据基于各自对应的会话控制进行编码。本申请中通过分割图像并创建匹配的会话控制进行编码，该方式通过软件侧程序调度实现，无需受限于编码器的自身硬件性能。
