A display device configured to consume less power is disclosed. Said method utilizing at least the following steps: providing a strip-shaped carrier, which is populated on at least one side with a plurality of semiconductor light sources; arranging at least one electrical line on the carrier; and casting the at least one electrical line on the carrier. The connector module is mounted in the elongated housing at the inside side. The printer, onto which the sheet pack can be removably set includes an information reading unit for reading the information recorded in the recording member when the sheet pack is set onto the printer. Another method for removing contouring effects involves decoding the block-encoded signal to obtain a decoded sequence of video frames, detecting a contouring effect by evaluating the macroblock mode and DCT coefficient information from the decoded signal, and filtering one or more blocks correlating to the detected contouring effect. In the camera accessory, the accessory-side communication control device executes control so as to ensure that the signal assuming a level corresponding to the first truth value is not continuously output from the fifth accessory contact point any longer than the predetermined time length while the operating voltage supply from the camera body is provided via the first accessory contact point.
