Embodiment 1

[0025] figure 1 It is a schematic diagram of a device for generating image mirror data provided by Embodiment 1 of the present invention. The device for generating image mirror image data can be applied to automatic teller machines or other automatic deposit and withdrawal devices. see figure 1 , the generating device of the image mirror data includes:

[0026] Temporary memory 10, used for storing the raw image data collected by the collection device;

[0027] The read address control module 30 is used to perform decremental calculations from the end address of the storage space of the original image data in the temporary memory 10 until reaching the first address of the storage space;

[0028] The data reading module 20 is configured to read data according to the address calculated by the reading address control module 30 .

[0029] Wherein, the storage space of the temporary memory includes a plurality of storage units, and each storage unit usually stores one byte of d...

Embodiment 2

[0039] image 3 It is a schematic structural diagram of the device for generating image mirror image data provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the foregoing embodiments. In this embodiment, a mirroring control module is added to enable the read address control module to perform a decrement operation.

[0040] see image 3 , in this embodiment, the generating device of the image mirror image data also includes:

[0041] The mirror image control module 40 is configured to enable the read address control module 30 to perform a decrement operation.

[0042] Since the banknotes put into the ATM are not all in the same direction, when the banknotes put in are reversed, the original image data collected by the CCD or CIS through sequential scanning is the image mirror data of the normal banknotes, no need The image mirror data is obtained by reverse reading. Therefore, in this embodiment, the control of the read address c...

Embodiment 3

[0048] Figure 4 is a schematic structural diagram of the device for generating image mirror image data provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the foregoing embodiments, and in this embodiment, the number of the temporary storages is set to be at least two.

[0049] The temporary memory usually corresponds to two working states, one is the writing state, and the other is the reading state. In the writing state or reading state, the temporary memory is in a locked state to ensure the integrity and correctness of the stored data, that is, the temporary memory cannot be written and read at the same time. Due to the above characteristics, the temporary memory cannot perform read and write operations at the same time, which seriously affects the generation efficiency of image mirror data. Therefore, in this embodiment, the number of the temporary storage is at least two.

[0050] Exemplarily, the number of temporary storag...

Abstract

The embodiment of the invention discloses an image-mirror-data generating method and device and an automatic teller machine. The image-mirror-data generating device comprises a temporary storage device for storing image original data collected by a collection device, a read-address control module for conducting decreasing calculation from a tail address of storage space of the image original datain the temporary storage device to a head address of the storage space and a data reading module for reading data according to the addresses calculated by the read-address control module. According tothe image-mirror-data generating device in the embodiment, the read-address control module achieved through programmable gate arrays inversely reads the sequentially-stored image original data, and image mirror data can be obtained. Image-mirror-data generation can be achieved in the data transmission process, the operation amount of later image processing is reduced, operation time of later image processing is shortened, and the image data treating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method, device and automatic teller machine for generating image mirror data. Background technique [0002] Automated teller machine, or ATM, refers to a small machine set up by a bank in different locations, using a tape on a credit card-sized plastic card to record the customer's basic account information (usually a bank card), so that the customer can withdraw money through the machine. Bank counter services such as remittances, deposits, transfers, etc. The automatic teller machine can store multiple banknotes and transport them to the temporary storage box through the transport path. [0003] Before the ATM machine transports the banknotes to the temporary storage box, the holographic optical image of the banknotes can be recorded by the image sensor, and the characteristic image to be identified can be converted into a basic digital signal that can be processed ...
