| Vertical lines on the monitor screen. | Recording a very brightly lit subject can cause a vertical band to appear in the monitor screen image. | This is a CCD phenomenon known as "vertical smear", and does not indicate malfunction. Note that vertical smear is not recorded with the image in the case of a snapshot, but it is recorded in the case of a movie. |
| Out of focus images. | The subject is outside the shooting range of the camera. | Record within the allowable shooting range. |
| Digital noise in images. | Sensitivity is increased automatically for dark subjects. Greater sensitivity increases the chance of digital noise. | Use a light or some other means to illuminate the subject. |
| Color of the playback image is different from the image on the monitor screen during recording. | Sunlight or light from another source is shining directly into the lens during recording. | Position the camera so sunlight does not shine directly into the lens. |
