FIG. 1 is a conceptual diagram conceptually illustrating image generation in a general full-screen transmission type image sensor, in which a separate storage area 10 having a pixel array size is allocated to a lower end of a pixel array. It is about.

As shown in FIG. 1, unlike the area sensor, a general full screen transmission type image sensor does not have a storage space for image data in the exposure surface of the sensor. Accordingly, as shown in FIG. 1, the image generation in the image sensor of the full-screen transmission method in which the storage area exists at the lower end of the sensor is performed by directly moving the image formed on the sensor surface in a vertical direction in order to separate storage area 10 at the lower part. And a pixel signal as a video signal in a horizontal direction in the storage area 10.

In view of the image generation feature of the full-screen transmission type image sensor, and proposes an image generation control device and method for controlling to generate all the video signals of the stationary or moving object in the full-screen transmission type image sensor.

The present invention generates a stationary object as an image of one m × n size (where m and n are determined by the size of the pixel array of the image sensor, that is, the number of pixels). The image is generated in m x k (where m is the number of horizontal pixels of the image sensor and k is the length of the image to be generated) without stopping.

In detail, when an image of a stationary object is generated, an image sensor of a full screen transmission type moves an image formed on a sensor surface to a storage region at a predetermined high speed, and then the pixel corresponding to the lowest line of the pixel array in the storage region. It is possible to control the signal to be generated sequentially, and when the moving object is generated, if the moving object is a very long object, it may exceed the limit of the number of pixels of the image sensor. By accurately moving the charge accumulated in the sensor in the same direction and the same speed as the moving object, the same part of the image is continuously controlled until the pixel signal corresponding to the lowest line is output.

Signal and horizontal transmission signal) to be sent to the image sensor of the full-screen transmission.

Specifically, the image generation control device of the present invention includes a vertical transmission signal generator 120 for generating a vertical transmission signal for controlling to transmit the pixel signal of each line in the vertical direction in the pixel array of the full-screen transmission image sensor; A horizontal transmission signal generator 140 generating horizontal transmission signals as many as the number of pixels in each line in order to transmit the pixel signals stored in the storage area of the image sensor in a horizontal direction and output them as actual image signals; A signal of the vertical transmission signal generator 120 and the horizontal transmission signal generator 140 in response to a mode input signal Mode indicating whether the image is in a capture mode or an image generation mode for a moving object. The state machine 100 is configured to generate first and second control signals control_v and control_h for controlling a generation operation.

Here, the image generation control device outputs an electronic shutter timing adjustment signal corresponding to the exposure time when generating an image of a stationary object to the image sensor, which is the same as that of the conventional image generation control device. Since the description is not related to the technical features of the present invention, the detailed description of the present invention and description in the drawings will be omitted.

Referring to Figure 2, the operation of the image generation control device of the present invention will be described in detail.

First, when a video generation start signal (Capture) is input to generate an image from a full-screen transmission type image sensor, and a signal to generate an image for a stationary object is input as a mode input signal (Mode), the state machine 100 is input. Outputs the first control signal control_v and the vertical transmission signal generator 120 outputs the vertical transmission signal as many as the number of lines of the pixel array in response to the first control signal control_v output from the state machine 100. In this case, the image sensor of the full screen transmission type is controlled to vertically move the image formed on the sensor surface to the storage area at a predetermined high speed. At this time, the state machine 100 maintains the first control signal control_v in an enabled state for a predetermined period of time in which the vertical transmission signal generator 120 can output the vertical transmission signals corresponding to the number of lines of the pixel array. . When the vertical movement to the storage area is completed, the state machine 100 alternately outputs the first control signal control_v and the second control signal control_h by the number of lines of the pixel array, and the vertical transmission signal generator 120 ) Outputs the vertical transmission signal in response to the first control signal control_v, and the horizontal transmission signal generator 140 outputs the horizontal transmission signal to the image sensor of the full screen transmission method in response to the second control signal control_h. . At this time, the horizontal transmission signal generator 140 generates and outputs a horizontal transmission signal corresponding to the number of pixels of the line in response to the second control signal control_h. Accordingly, the image sensor of the full-screen transmission method generates a pixel signal stored in the storage area sequentially by the vertical transmission signal and the horizontal transmission signal output from the image generation control device of the present invention to finally generate the image signal for the stationary object. Done.

On the other hand, when a video generation start signal (Capture) is input to generate an image from the image sensor of the full-screen transmission method, and a signal to generate an image for the moving object is input to the mode input signal (Mode), the state machine 100 Is alternately outputting the first control signal control_v and the second control signal control_h until the end of the movement of the moving object, and in response to the vertical transmission signal from the vertical transmission signal generator 120 and the horizontal transmission signal generator 140. And the horizontal transmission signal are alternately outputted to the image sensor of the full screen transmission method. At this time, the horizontal transmission signal generator 140 generates and outputs a horizontal transmission signal corresponding to the number of pixels of the line in response to the enabled second control signal control_h. Accordingly, the full-screen transmission type image sensor corresponds to the lowest line of the exposure area pixel array when the image signal of the moving object is generated by an appropriate combination of the vertical transmission signal and the horizontal transmission signal output from the image generation control device of the present invention. The image of the long moving object can be generated without blur by being controlled so that the same part of the image is continuously formed until the pixel signal is output.

First, when an image generation start signal (Capture) and a mode input signal (Mode) are input (200), it is determined whether the mode input signal (Mode) is a stop mode (210). The transmission signal is generated (220) and output to the image sensor of the full screen transmission method, and the vertical transmission signal and the horizontal transmission signal are alternately generated by the number of lines of the pixel array (230) and output.

On the other hand, when the mode input signal (Mode) is not in the stop mode, that is, in the movement mode, the vertical transmission signal and the horizontal transmission signal are alternately generated (240), it is determined whether the movement of the moving object is finished (250) The vertical transmission signal and the horizontal transmission signal are alternately generated until the end of the object, and the signal generation is stopped at the end of the moving object.
