Camera Hal OEM模块 ---- 3dnr算法流程( 三 )

生活百科流程


3，me 流程 3.1 构建
使用 in 参数的地址
orig_image.gpuHandle = out->private_data;orig_image.bufferY = (unsigned char *)in->src_frame.addr_vir.addr_y;orig_image.bufferU = orig_image.bufferY + threednr_handle->width * threednr_handle->height;orig_image.bufferV = orig_image.bufferU;
3.2 构建
使用 ->，即在中通过 -> 申请的，并且在 ess 中 作为scale的dst
small_image.cpu_buffer.bufferY = (unsigned char *)threednr_handle->small_buf_vir[cur_frm];small_image.cpu_buffer.bufferU = small_image.cpu_buffer.bufferY + threednr_handle->small_width * threednr_handle->small_height;small_image.cpu_buffer.bufferV = small_image.cpu_buffer.bufferU;small_image.cpu_buffer.fd = threednr_handle->small_buf_fd[cur_frm];

Camera Hal OEM模块 ---- 3dnr算法流程

文章插图
3.3 构建
使用上面的和
process_param.proc_param.cap_new_param.small_image = &small_image;process_param.proc_param.cap_new_param.orig_image = &orig_image;process_param.callWay = 1;
3.4 跑
是去执行降噪算法的指令，之前所有的准备工作都是为了这步
ret = sprd_mfnr_adpt_ctrl(threednr_handle->proc_handle, SPRD_MFNR_PROC_CAPTURE_CMD, (void *)&process_param);
到这里，3dnr的算法流程已经全部走完了，我们通过一个实际暗环境拍照的log来巩固下这个流程
