no. 1 Embodiment approach

[0072] In this embodiment, judgment information is inserted between two adjacent line data in addition to the synchronization code, and by performing this process, it is detected that there is unreproducible line data.

[0073] figure 1 It is a diagram showing the configuration of the solid-state imaging device 1000 according to the first embodiment.

[0074] The solid-state imaging device 1000 is a digital camera such as a digital still camera or a digital video camera.

[0075] figure 1 The illustrated solid-state imaging device 1000 includes a solid-state imaging element 11 , an AFE unit 100 , a serial data transmitting and receiving device 200 , an image processing unit 310 , and a display unit 320 .

[0076] figure 1 The solid-state imaging element 11 and the AFE section 100 in the Figure 5 The solid-state imaging element 11 and the AFE unit 100 in 1 are the same, so detailed description thereof will not be repeated.

no. 2 Embodiment approach

[0155] In the present embodiment, when it is determined that there is line data that cannot be played back, a process of retransmitting the line data corresponding to the line data that cannot be played is performed.

[0156] image 3 It is a diagram showing the configuration of a solid-state imaging device 1000A according to the second embodiment.

[0157] The solid-state imaging device 1000A is a digital camera such as a digital still camera or a digital video camera.

[0158] image 3 The solid-state imaging device 1000A shown with figure 1 The solid-state imaging device 1000 shown is different in that it has a serial data transmitting and receiving device 200A instead of the serial data transmitting and receiving device 200 . Other than that, it is the same as that of the solid-state imaging device 1000, so detailed description thereof will not be repeated.

Abstract

A transmission unit (210) includes an insertion unit (21) which performs multiple insertion processing for inserting judgment information between each two adjacent line data of a plurality of consecutive line data included in serial image data. A data format conversion unit (13) uses a transmission path (14D) to transmit post-insertionserial image data, in which a plurality of judgment information has been inserted, to a reception unit (220). The reception unit (220) includes a data format conversion unit (15) which sequentially detects a plurality of judgment information from the post-insertion serial image data received from the transmission path (14D) and judges whether unreproducible line data exists based on at least a portion of the detected plurality of information.

Description

technical field [0001] The present invention relates to a serial data transmitting and receiving device and a digital camera for transmitting serial data. Background technique [0002] In recent years, in solid-state imaging devices such as digital still cameras and digital video cameras, the amount of image data to be processed has been increasing. Therefore, in recent years, solid-state imaging devices having circuits using LVDS (Low Voltage Differential Signaling: Low Voltage Differential Signaling) signals capable of rapidly processing data have been increasing. [0003] Patent Document 1 discloses a solid-state imaging device using a differential signal which is an LVDS signal. Next, a solid-state imaging device using a differential signal will be described. [0004] Figure 5 It is a diagram showing a conventional solid-state imaging device 500 using a differential signal. [0005] Figure 5 The illustrated solid-state imaging device 500 includes a solid-state imagi...
