刚刚又发现不打印返回值也会一卡一卡的了

其中模块的代码

import sensor, image, time,pyb
def find_red_blob(count_flag):
    red_threshold=(1, 53, 4, 127, 127, 10)
    sensor.reset()
    sensor.set_pixformat(sensor.RGB565)
    sensor.set_framesize(sensor.QQVGA)
    sensor.skip_frames(10)
    sensor.set_auto_gain(False)
    sensor.set_auto_whitebal(False)
    clock = time.clock()
    count=0
    while(True):
        count+=1
        number=0
        img = sensor.snapshot().lens_corr(strength = 1.8, zoom = 1.0)
        red_blob1 = img.find_blobs([red_threshold],roi=(53,0,45,30))
        red_blob2 = img.find_blobs([red_threshold],roi=(0,40,45,30))
        red_blob3 = img.find_blobs([red_threshold],roi=(53,40,45,30))
        red_blob4 = img.find_blobs([red_threshold],roi=(106,40,45,30))
        red_blob5 = img.find_blobs([red_threshold],roi=(53,80,45,30))
        if red_blob1!=[]:
            img.draw_rectangle(red_blob1[0][0:4])
            img.draw_cross(red_blob1[0][5], red_blob1[0][6])
            number+=1
        if red_blob2!=[]:
            img.draw_rectangle(red_blob2[0][0:4])
            img.draw_cross(red_blob2[0][5], red_blob2[0][6])
            number+=1
        if red_blob3!=[]:
            img.draw_rectangle(red_blob3[0][0:4])
            img.draw_cross(red_blob3[0][5], red_blob3[0][6])
            number+=1
        if red_blob4!=[]:
            img.draw_rectangle(red_blob4[0][0:4])
            img.draw_cross(red_blob4[0][5], red_blob4[0][6])
            number+=1
        if red_blob5!=[]:
            img.draw_rectangle(red_blob5[0][0:4])
            img.draw_cross(red_blob5[0][5], red_blob5[0][6])
            number+=1
        #print(number)
        if count>count_flag:
            break
        return number
主函数的代码：
import sensor, image, time
import black_blob,red_blob
while(True):
    
    #print(clock.fps())              # Note: OpenMV Cam runs about half as fast when connected
    red_blob.find_red_blob(1000) 
    #black_blob.find_black_blob(1000,0,0)
    a=red_blob.find_red_blob(1000)
    #print(a)
