PAS6167 拍照插值死机

PAS6167 拍照插值死机

现象与分析：

现象为第一次拍照正常，第二次拍照死机或白屏。

原因分析：第一次拍照分配内存没有释放，第二次再插值拍照会再申请内如内存小就会分配不到内存出问题，从而导致死机问题

09a的code 容易出现“插值拍照后内存不释放”问题，这个问题23C与23D都出现过

解决方法：
修改代码，把以下代码

 #ifdef __Support_Image_Interpolate__

        if (image_interpolate == KAL_TRUE)

        {

                 kal_uint16 * inter_buff;

                 inter_buff = med_alloc_ext_mem(image_real_width*image_real_height*2);

                EXT_ASSERT(inter_buff, image_real_width, image_real_height, 0);

                 PAS6167_Interpolate(176,144,(kal_uint8 *)capture_mem_param.capture_buff_addr,(kal_uint8 *)inter_buff);

                 CAM_FREE_EXT_BUFFER();                    

                 cam_context_p->extmem_start_address = (kal_uint32)inter_buff;

                 jpg_encode.image_buffer_address = (kal_uint32)inter_buff;

                 cam_context_p->image_width = image_real_width;

                 cam_context_p->image_height = image_real_height;

        }

        #endif

  

 修改成如下：

 

 

       #ifdef __Support_Image_Interpolate__

        if (image_interpolate == KAL_TRUE)

        {

                 kal_uint16 * inter_buff;

                 inter_buff = med_alloc_ext_mem(image_real_width*image_real_height*2);

                 EXT_ASSERT(inter_buff, image_real_width, image_real_height, 0);

                 PAS6167_Interpolate(176,144,(kal_uint8 *)capture_mem_param.capture_buff_addr,(kal_uint8 *)inter_buff);                    

                 cam_context_p->extmem_start_address = (kal_uint32)inter_buff;

                 jpg_encode.image_buffer_address = (kal_uint32)inter_buff;

                 cam_context_p->image_width = image_real_width;

                 cam_context_p->image_height = image_real_height;

                 CAM_FREE_EXT_BUFFER();

        }

        #endif

修改后反复测试，没有再出现死机现象
