Abstract

An image capturing system (10) includes an integrated circuit (18) having an interface block (22) that generates signals for controlling the readout of voltages from photodetectors (36) arrayed in an optical sensor (20). The voltage generated by the photodetector (36) in response to light at a pixel site is read and reset without destructively destroying the voltage generated by other photodetectors that surround the pixel site. Pixel elements (34) are grouped as a macroblock (20A) and the analog sense signals from the macroblock (20A) are read in real time to a sensing block (26). The sensing block (26) amplifies the analog sense signals for conversion to digital signals in YUV format.

Description of the Invention (1) Background of the Invention The present invention relates to the semiconductor industry, and more particularly to integrated image processing circuits. High-resolution systems such as scanners and digital cameras can project an object through an optical lens to an optical sensor to receive light to capture its image. The optical sensor is fabricated on a semiconductor die with an array of light-sensitive measuring devices, such as a charge junction device, a photodiode, or a photoelectric crystal. The light-sensitive semiconductor device generates a proportional phase. The method of the prime signal is to respond to the light received by the object, and the signal can be processed through an image processing circuit to generate viewable image data. The imaging system senses the proportional phase signal from the optical sensor and generates digital data in the sensing circuit. Because the data is read by the optical sensor in this way, the digital data It is stored in a format that is acceptable for compression and re-set into the data block. An image frame includes brightness and chroma information, and it must be encoded and compressed to reduce the bandwidth required to transmit image data to the user. This step, which constitutes a data block before data is compressed, will cause additional data processing operations and data delays. Therefore, it is necessary to have an improved image system that can read data in the form of blocks by optical sensors. More preferably, the data is read in a ready-to-compress format, without the need for additional data. The diagram is briefly written, and illustrated in Figure 1.

Detailed description of the diagram FIG. 1 illustrates an image capture An omnidirectional view of part 10 of the system is referred to as an imaging device or a chip in the camera. This is a part of the image capture system, where the integrated circuit 18 captures a certain Image 12 is processed, and the analog phase signal is converted into 24-bit RGB digital data in a format that can be displayed by display device 30. Further processing can convert the color space to an 8-bit 4: 2: 0 The color space of the format YcbCr (brightness, blue chroma, red chroma) is sometimes also referred to as the "YUV" format or color space. The package 28 is loaded with an integrated circuit 18 and has a cover 14 where The transparent area 16 is used to receive the light reflected from the image 12. The reflected light is received by the optical sensor 20 formed by the area of the integrated circuit 18. The optical sensor 20 is an array of photosensitive semiconductor devices. It is used as a light detector and has the function of a pixel sensor. The transparent area 6 is used as a lens 'to focus light on the focal plane'. Optical sensors are placed on it. Or, it is located on the upper cover 14 and a lens (not shown in the figure) placed between the image 12 and the optical sensor 20 to collect light on the optical sensor 20. The transparent area i 6 is projected on the optical sensor Detector 20 light detection The light on the device can be proportional to the light received from the self-image. 2 The paper size applies the Chinese National Standard (CNS) A4 specification (210 x 297 public love).

In a preferred embodiment, the light detectors in the optical sensor 20 are arranged in an array manner above the core region of the 352 by 288 action pixel position. By increasing the core area by about 20%, for example, the core area becomes 418 times 344 pixels, and the flicker compensation of the received image 12 can be obtained. The core area of the user-addressable voxel position can be expanded with additional voxel positions that can add scale and isolation to the user-addressable voxel position. Except for the optical sensor 20 In addition, the integrated circuit 18 also has an interface block 22, which can generate a signal for controlling the reading of radon by the optical detector in the optical sensor at each pixel position. The digital processor 24 can generate start and end addresses for the interface block 22, and process signals that control the horizontal transpose, integration time, and scale protocol. After receiving the analog sensing signal from the optical sensor 20, the sensing block 26 amplifies the analog sensing signal and converts the analog sensing signal into a digital representation. FIG. 2 is a block circle of the integrated circuit is as described in FIG. 1. This figure uses the same reference numbers to indicate the same elements. The integrated circuit 18 includes an optical sensor 20 divided into local areas or giant blocks 20A and 20B as shown in the figure. The purpose of adding the letters A and B after the reference number is to indicate a specific group of pixel locations within the optical sensor 20, i.e., giant blocks. Megablocks 20a and 20B may contain various numbers of pixel positions, and in a more specific embodiment, 'is set to have pixel positions of 18 by 18.

Description of the invention (4) Giant block of size 20A and 20B allow color information to be transposed between giant block boundaries. In the RGB system, the optical sensor 20 may include a device corresponding to red light in a row, a device corresponding to blue light in a row, and a device corresponding to green light in a third row. It should be noted that, the number of pixel positions in the giant blocks 20A and 20B, and the number of giant blocks in the optical sensor 20, neither of which will limit the present invention. The giant blocks 20A and 20B are located at the start and end addresses of the optical sensor 20. It should be more noted that the 'positions of the start and end addresses of the giant blocks 2 0 A and 2 0 B' can be phase-based, and the optical sensor 20 moves within. The interface block 22 receives the starting row and column addresses from the digital processor 24, and generates a signal that can control the pixel position in the optical sensor 20. For example, the interface block 22 provides a control signal to the pixel position in each of the 354 columns by 448 rows of the optical sensor 20. The interface block 22 generates, for example, a “horizontal reset” signal, a “horizontal reset” signal, and a “transpose” signal to each row in the optical sensor 20 (refer to FIG. 3), and a “vertical row "Reset" signal to each vertical row in the optical sensor 20. In this way, the interface block 22 according to the horizontal and vertical rows in the optical sensor 20, and the control signal generated by the position of each pixel can generate X-Y addressability, where X and Y are respectively Indicates the number of rows and columns. It should be noted that the X-Z addressability in the optical sensor 20 may provide the ability to access individual pixel positions in order to read the voltage generated by the photodetector at the pixel position. Generally used to obtain low-noise, high-accuracy all-crystal voxel signal sensing method is to measure the voxel twice.

Description of the Invention (5) Phases and elements 34 Firstly, the real signals accumulated on the light detector 36 (Charge) First sensing. The "horizontal reset" and "vertical reset" signals reset the element π prime 34. After the pheromone element 34 is reset to the preset “full black” or reference level state, the second pheromone element 34 sensing is performed. Previous technical inventions have provided χ-γ addressability to obtain signals at a single pixel location and reset the measurement. However, in the procedure of the prior art invention, 'all other voxel positions on the same row will be reset', thus destroying the information of these voxels in the current frame. Compared with the previous technical invention, 'the voltage generated by the photodetector 3 6 located at a particular pixel position' reads and resets it without damagingly affecting any other pixel position. The voltage 値 generated by the photodetector 36. In this way, the present invention can provide χ_γ addressability and readability, and can reset the position of each pixel. When the data transmitted from each pixel position is selected to be read, the voltage 値 generated by the light detector at the pixel position corresponding to the light source will be transmitted to a programmable program in the sensing block 26. A gain amplifier (not shown in this figure) is converted into a digital signal. Each analog sensing signal transmitted to the “vertical signal line” (refer to Figure 3) will be amplified, and its gain is determined by the control data 値. When the pixel positions are divided into groups such as the giant block 20A within the optical sensor 20, all the analog sensing signals generated by the light detector corresponding to the giant block 20A, They all have common control data, which is used to control the amplification of analog signals sent by the giant block. In general use, a programmable register (not shown in this figure) can provide "immediate" benefit control for color balance and exposure.

Description of the invention (8) The control circuit of element 3 4 can be used in a “non-destructive” manner, Read the voltage generated by the photodetector on a single element. When the voltage generated at the single pixel position is read and reset, the electricity generated by the optical debt detector at other pixel positions will not be changed. With the random access nature of the optical sensor 20, image data can be processed to perform a "zoom in" function on specific favorite areas. In addition, with the function of individual pixel reset of the optical sensor 20, the image data of single or multiple regions outside the ROI can be selected and can be read out and processed in the current frame. This allows functions such as motion estimation, flicker compensation, and focus processing algorithms to be implemented on the "sensor." The prior art sensing system reads data from the sensor, stores the data in the memory buffer, and then selects the data corresponding to the giant block from the memory buffer, and then the giant block Send to video encoder. In addition, in the "sensing system of the prior art", the data is read by the sensor in a progressive manner. Therefore, ′ is the phase information of the favorite area read by the sensor. All the sensor data above the horizontal line of the favorite area must be read and stored first. It should be noted that the process of 'reading additional data by the sensor to retrieve the desired data, storing the data in memory, and reformatting the data into giant blocks will cause the system to Delays. In other words, the data required by the prior art sensing system cannot be read directly in the appropriate macroblock format, but must be processed before sending the macroblock to the video encoder β. The processing procedure will cause a delay between reading data from the sensor and transmitting the data to the video encoder. In contrast, the present invention allows the data of specific favorite areas to be optically sensed. • This paper size applies the Chinese National Standard (CNS) A4 specification (2J0 X 297 mm).
