A camera image display system (100, 200), comprising: a camera unit that includes a camera, an image dividing unit generating divided images (p) by dividing an entire image captured by the camera, an encoder respectively converting the divided images (p) into JPEG divided images, and a wireless transmitter transmitting the JPEG divided images wirelessly; a wireless receiver that receives the JPEG divided images transmitted by the wireless transmitter; a current position detector that detects a current position of a vehicle having the wireless receiver; a display unit that displays images; a decoder that decodes the JPEG divided images received by the wireless receiver; an image display controller that controls the display unit to respectively display the decoded divided images at positions on the display unit corresponding to positions of the divided images (p) in the entire image; a transmission-and-reception status detector (18, 32) that detects a transmission-and-reception status of the JPEG divided images between the wireless transmitter and the wireless receiver; a channel-switching controller (19, 19', 33, 33') that has at least three channels in a wireless frequency band used by the wireless transmitter and the wireless receiver, wherein the channel-switching controller (19, 19', 33, 33') controls the wireless transmitter and the wireless receiver to sequentially switch the at least three channels based on the detected transmission-and-reception status, and changes a switching order of the at least three channels in accordance with a MAC address of the wireless transmitter, and wherein the channel-switching controller (19, 19', 33, 33') determines whether the detected current vehicle position is within a predetermined area and controls the wireless transmitter and the wireless receiver to switch the channels when the detected current vehicle position is within the predetermined area; and an image quality adjuster that adjusts at least one of an image size of the JPEG divided images, a compression rate for encoding the divided images into JPEG format, and a frame rate based on the detected transmission-and-reception status. a camera unit that includes a camera, an image dividing unit generating divided images (p) by dividing an entire image captured by the camera, an encoder respectively converting the divided images (p) into JPEG divided images, and a wireless transmitter transmitting the JPEG divided images wirelessly; a wireless receiver that receives the JPEG divided images transmitted by the wireless transmitter; a current position detector that detects a current position of a vehicle having the wireless receiver; a display unit that displays images; a decoder that decodes the JPEG divided images received by the wireless receiver; an image display controller that controls the display unit to respectively display the decoded divided images at positions on the display unit corresponding to positions of the divided images (p) in the entire image; a transmission-and-reception status detector (18, 32) that detects a transmission-and-reception status of the JPEG divided images between the wireless transmitter and the wireless receiver; a channel-switching controller (19, 19', 33, 33') that has at least three channels in a wireless frequency band used by the wireless transmitter and the wireless receiver, wherein the channel-switching controller (19, 19', 33, 33') controls the wireless transmitter and the wireless receiver to sequentially switch the at least three channels based on the detected transmission-and-reception status, and changes a switching order of the at least three channels in accordance with a MAC address of the wireless transmitter, and wherein the channel-switching controller (19, 19', 33, 33') determines whether the detected current vehicle position is within a predetermined area and controls the wireless transmitter and the wireless receiver to switch the channels when the detected current vehicle position is within the predetermined area; and an image quality adjuster that adjusts at least one of an image size of the JPEG divided images, a compression rate for encoding the divided images into JPEG format, and a frame rate based on the detected transmission-and-reception status.
