Saint Bernard (definitely introduced)
Sometimes dogs may be very quiet when we are watching TV. Sitting around us watching TV, but sometimes they seem boring, so is this because it has something to do with the TV programs we watch? If so, can dogs understand TV? It turns out that there are many factors that play a role in whether dogs are attracted to pictures, but the most critical one is their eyesight.
Dogs have better flicker perception than humans, which is consistent with the claim that dogs are more sensitive to movement than humans. This also answers a rare question: Why do most dogs have no interest in TV, even when other dogs appear on TV? The reason is that the picture on the average TV screen refreshes 60 times per second, which is higher than the human flash perception ability of 55 Hz. In the human eyes, it is a continuous image that is smoothly integrated together. However, dogs can see 75 Hz light, and the pictures on TV look less realistic to dogs, making dogs pay less attention to the TV screen.
Of course, if the picture is interesting enough, some dogs seem to react to other similar and changing images that appear on the screen, regardless of whether the picture flashes or not. However, technological changes have led to more dogs watching TV. High-definition digital TVs have higher hertz numbers, and dogs see less glare. Therefore, more and more owners point out that when nature programs are broadcast on TV, their dogs are very interested in the pictures of animals moving.
However, although dogs will react to similar animals on TV or animals running fast, they are not interested in cartoon dogs, which sometimes makes owners feel very upset. Surprised. This difference illustrates how clearly and thoroughly dogs see the image of movement. When a dog sees a cartoon dog, he or she may not see an object moving, but cartoon characters and live animals move differently. Therefore, the dog sees something moving, but it knows that it is not a real dog or other animal.
For dogs, the pictures we watch on TV are somewhat unrealistic in their eyes, and sometimes the reason why they watch TV with us is probably because they are attracted by some of the characters on TV. Attracted by the sound.
