$this->input->post('photo') in model won't work to retrieve the image information. Because the images are stored in $_FILES not in $_POST. So you need to use the upload library in codeignitor like below.

In Controller:

public function update_profile() {
       $id = $this->session->userdata('id');
       $this->load->model('edit_profile_model');

       $config['upload_path'] = './uploads/';
       $config['allowed_types'] = 'gif|jpg|png';
       $config['max_size']  = '100';
       $config['max_width'] = '1024';
       $config['max_height'] = '768';

       $this->load->library('upload', $config);
       $this->upload->do_upload();//upload the file to the above mentioned path
       $this->edit_profile_model->update_db_user_info($id, $this->upload->data());// pass the uploaded information to the model
   }

In Model:

public function update_db_user_info($id, $imgdata) {
       $imgdata = file_get_contents($imgdata['full_path']);//get the content of the image using its path
       $data = array(
           'fullname' => $this->input->post('fullname'),
           'address' => $this->input->post('address'),
           'state' => $this->input->post('state'),
           'city' => $this->input->post('city'),
           'pincode' => $this->input->post('pincode'),
           'image' => $imgdata,
       );
       $this->db->where('id', $id);
       $this->db->update('userdetails', $data);
   }

To retrieve the image write a function in the model like below.

public function get_image($id){
       $this->db->where('id', $id);
       $result = $this->db->get('userdetails');
       header("Content-type: image/jpeg");
       echo $result['image'];
}

And also its not a good practice to store the image and retrieving from database. Instead of that try to store the image in a folder and store the path in the database like below.

In Model:

public function update_db_user_info($id, $imgdata) {
       $imgdata = $imgdata['full_path'];// get the path of the image
       $data = array(
           'fullname' => $this->input->post('fullname'),
           'address' => $this->input->post('address'),
           'state' => $this->input->post('state'),
           'city' => $this->input->post('city'),
           'pincode' => $this->input->post('pincode'),
           'image' => $imgdata,// change the type of image from blob to varchar or text
       );
       $this->db->where('id', $id);
       $this->db->update('userdetails', $data);
   }
